Information about the device
Value Protection Range technology (VPR+)
If properly dimensioned and operated, the dehumidifiers of the
VPR+series keep the humidity level steady around the clock
and, if needed, neutralize a great number of offensive smells.
The humidity is automatically regulated to the set level that
reliably prevents corrosion, condensation and mould formation.
A relative humidity between 45 and 50% provides better
protection than any other measure against corrosion and rust.
Rust mainly occurs at inaccessible, hardly visible spots.
In addition to the dehumidification and odour elimination, the
process air is further freed from dust and/or soot depending on
the used filter model.
The integrated pump ensures the discharge of the accumulating
condensate even over differences in height.
The fan comes with two stages to adjust the device
performance to the contaminations and conditions in the room.
Description of the device
The dehumidifiers of the VPR+ series use the principle of
condensation to automatically dehumidify rooms.
The fan sucks damp room air through the air inlet(3), the
evaporator and the condenser located behind it. The air is
cooled at the cold evaporator until it is below the dew point.
Water vapour contained in the room air precipitates on the
evaporator fins as either condensation or rime. The
dehumidified, cooled air is rewarmed at the condenser and
blown out at a temperature of approx. 5 °C above room
temperature.
The drier air thus conditioned mixes with the air in the room via
the air outlet(1). The humidity in the room where the device is
positioned is reduced as air constantly circulates through the
device. Depending on the air temperature and the relative
humidity, the condensed water either drops into the
condensation tray continuously or only during the defrost
phases.
To set the desired humidity level, a hygrostat with control
dial(8) is provided in the device's interior. This control dial can
be easily accessed once the filter flap(3) has been removed.
The device can reduce the relative humidity of a room to approx.
30%.
At a room temperature of 15°C, the devices emit 1.6 to 3 times
of their power consumption to the room air in form of heat (see
chapter Technical data, COP). Because of the heat dissipation,
which develops during operation, the room temperature can
therefore rise by approx. 1 to 3°C.
A high humidity level in the air (starting at 70%RH) provides
the perfect breeding ground for mould. However, the room air
must not be too dry either (<40%RH). Materials such as
leather or rubber become porous, and wood becomes brittle and
fissured.
For the storage of vehicles we recommend a relative humidity
between 45 and 50%. For other material-specific humidity
values please refer to the respective manufacturer's instructions
for the stored goods.
Additionally, the device comes equipped with an ionizer which
eliminates odours and bacteria from the room air, if required.
Depending on the model an integrated filter absorbs dust and /
or soot in the room air.
The incorporated pump helps to discharge condensate; in doing
so, it is possible to overcome a difference in altitude of up to
10m. That way, it is possible to discharge condensate across
several storeys.

Important information regarding the dehumidification performance and drying rate
The dehumidification performance depends on:
• the layout of the room
• the individual usage behaviour
• the room temperature
• the relative humidity
The higher the room temperature and relative humidity, the
greater the dehumidification performance or drying speed at
which a wet vehicle dries.
For use in living rooms, a relative humidity of approx. 50% is
sufficient. In store rooms and archives, the humidity should
generally not exceed a level of approx. 50%.
Dehumidification of garages
For the storage of vehicles we recommend a relative humidity
between 45 and 50%. For other material-specific humidity
values please refer to the respective manufacturer's instructions
for the stored goods.
How the room temperature influences the dehumidification
performance?
In the winter at decreasing mean temperatures of below 15°C
the dehumidifier's capacity and thus the room volumes to be
covered are disproportionately reduced.
This circumstance results from the physical correlations
between the room air's moisture absorption capacity at low
temperatures and the performance curve of condenser dryers
that may appear complex to the layman. In order to render these
complex correlations comprehensible for the typical user we
endeavour to briefly describe the recommended course of action
on the subject of capacity and performance limits of the DH-VPR
+ devices at low temperatures:

* The time for drying moisture
accumulated in the car body,
at the underbody and inside
the engine compartment as
well as in ribbings and
hollows could even be
significantly extended if there
is no air circulation!
Rule of thumb:
The higher the room temperature, the sooner will the
dehumidifier DH-VPR+ have "dried" the room air and therefore
all the vehicles in the garage. In contrast, the lower the room
temperatures, the longer will it take to completely dry wet
vehicles. To be sure, even at low temperatures the DH-VPR+
can quickly dry the air in the garage to the desired level, the car
and floor however remain moist.
On principle, it takes a disagreeably long time to dry wet
vehicles at temperatures below 15°C (up to several days), this
is particularly problematic considering the instant corrosion. It is
not due to the dehumidifier DH-VPR+ that the vehicle will not
dry, but rather the physical circumstances of humidity combined
with the evaporation behaviour (drying rate) of water.
A consequence of low temperatures is that on surfaces water
evaporates very slowly even at an ideal room climate of
50%RH. In simplified terms, this is due to the fact that at low
temperatures – insofar as relative humidity (%RH) is concerned
– the gradient of vapour pressure between the dry room air and
the water surface is very large, in terms of the absolute
humidity (g/m³), however, it is very small.
As a result, the water at wet vehicles situated in cold garages
evaporates very slowly even though the DH-VPR+ devices are
running at full capacity.
** Additional ventilation has a
favourable impact on the drying
duration for residual moisture
accumulated in the car body, at
the underbody and inside the
engine compartment as well as
in ribbings and hollows.
EN 8
Operating manual – dehumidifier / climate manager DH 30 VPR+ / DH 60 VPR+
Here a worst-case scenario:
A modern car wet with rain is parked in a garage along with a
classic vehicle. The room temperature is 4°C. Attributable to
evaporation of water at the still warm, wet vehicle, the relative
humidity in the garage quickly rises to 95%.
95% of relative humidity at 4°C mean that in absolute terms
only about 6g of water are bound in a cubic metre of air, for
that is the physical limit that can be absorbed.
For comparison:
At a room temperature of 21°C and 95%RH, 17g of water
are retained by a cubic metre of air. In other words, for every
100m³ of room air in the garage the air contains over 1litre
more of pure water (than at 4°C) in the form of water vapour.
This quickly adds up to several litres of water in the garage! And
it results in the DH-VPR+ withdrawing next to none of the water
from the room air at these low temperatures, because it is
unable to extract any. Hardly any water is bound in the room air,
rendering dehumidification a physical impossibility.
The higher the room temperature, the more moisture
can be absorbed by the room air
Temperature in the
garage:
Relative humidity:
4 °C 21 °C
50 % 95 % 50 % 95 %
3 g/m³ 6 g/m³ 9 g/m³ 17 g/m³
Moisture retained
by the room air:
(absolute humidity)
Consequence for
drying wet
vehicles:
With 95% the relative humidity given in our example is rather
high. The vehicle's corrosion and the mould formation at the
walls started immediately. It does not take a great amount of
absolute humidity in the air to get the processes of corrosion
and mould growth going. It is enough if water is bound as
vapour, even though expressed in absolute terms (g/m³) the
values are not very impressive.
Vapour pressure
difference:
3 g/m³
Low drying speed
(minor vapour pressure
difference)
Vapour pressure
difference:
8 g/m³
High drying speed
(great vapour pressure
difference)
And there is another aspect:
Due to the minor absolute vapour pressure differences, the
drops of water on the wet car do not evaporate. It stays wet
despite the DH-VPR+ operation. And the situation is the same:
Low temperatures --> minor differences in the air's moisture
content with regard to the absolute humidity level (g/m³) in spite
of large differences regarding the relative humidity.
Even at low temperatures, the DH-VPR+ keeps the room climate
at the desired level. If new water enters the scene at these low
room temperatures by way of a wet vehicle and the temperature
remains low, the wet vehicle will dry very slowly, hence causing
the humidity inside and at the car to rise to a corrosion-prone
level. Dry keeping is not a problem. Quick drying, however, is a
physical impossibility.
Conclusion:
Using DH-VPR+ devices classic cars can be stored and
showcased during the winter to a temperature of 0°C. Yet the
capacity is disproportionately reduced (see table Correlation
between the temperature in the garage and duration of the
drying process).
However, if both the storage and a quick drying of wet vehicles
are required – also during the winter – you will additionally have
to ensure heating in order to increase the drying rate for wet
vehicles so as to effectively prevent corrosion and mould
growth.
So, if the classic car garage is used all through the year and/ or
there are often wet cars inside, we recommend room
temperatures of at least 15°C. If water only sporadically enters
the garage, there is no need for permanent heating. It will be
sufficient to heat the garage to a level between 15°C and 20°C
during the drying phase lasting several days. On these grounds,
we recommend a general on-demand heating option to achieve
a reasonable temperature for drying the garage quickly.
Depending on the temperature, a heating phase of 3 to 7days
should normally suffice to ensure a fail-safe drying process.
This period can be considerably reduced by the use of fans.
Especially for a quick drying in the car body, at the underbody
as well as in ribbings and hollows we always recommend the
use of fans for wet classic cars (see table Correlation between
the temperature in the garage and duration of the drying
process).
The more frequently and extensively the cars are used, the
higher should be the average temperature in the garage so as to
attain a quick and fail-safe drying process and thus to prevent
corrosion and mould.

• The condensation drain hose should be no longer than
25m.
• The end of the condensation drain hose must always be
free and may not protrude into the water.
• While laying the condensation drain hose, make sure that
– even at low temperatures – the water inside the hose
cannot freeze.
Switching the device on
1. Ensure that the condensation drain hose has been laid and
connected properly. Do not create tripping hazards.
2. Ensure that the condensation drain hose is not bent or
jammed and that there are no objects on the condensation
drain hose.
3. Ensure that the condensation can run off properly.
4. Insert the mains plug into a properly secured mains socket.
Regulating the room humidity level
1. Set the desired humidity level via the control dial(8) of the
hygrostat.
2. Turn the control dial to the middle of the word NORMAL.
After 2days a humidity level between 50 and 55% should
be reached.
3. Then check the humidity level by means of a
thermohygrometer. If the air is too dry (insufficient humidity
level), turn the hygrostat control approx. 1cm to the left, if
the air is too humid (excessive humidity), turn it approx.
1cm to the right (towards the word DRIER).
4. Every time you have changed the hygrostat setting wait for
2days, then repeat the procedure until the desired humidity
level is reached.
Automatic defrost
If the room temperature is lower than 15°C, the heat exchanger
will freeze during dehumidification. The device will then carry
out an automatic defrost. The duration of the defrost process
can vary depending on the room temperature. The lower the
temperatures, the longer the defrost period.
Ionization
Ex factory, the dehumidifier DH-VPR+ comes equipped with a
special, high-quality NTP air purification unit. In its plasma zone,
airborne odours, pollutants and microorganisms, as are found
primarily in the recommended fields of application for the VPR
+series, can be neutralized efficiently through oxidative
conversion.
When contaminated air flows through the ionizer unit, it is
neutralized by means of electrical excitation to form singlet
oxygen with broken down hydrogen and oxygen molecules,
which are harmless for humans and nature.
The ionizers employed in the VPR+series are able to
continuously neutralize most types of these application-specific
odorous substances in the room air. As a consequence the
odour nuisance is reduced slowly, but steadily.
Ionization control
The ionization function can be switched on via button10. When
the ionization function is activated, the button(10) is
illuminated.
The device comes with a controller for 5intensity levels(11).
With the settings 1 to 4 the production of singlet oxygen can be
ð Upon reaching the desired humidity value, the compressor
switches off automatically.
ð The fan keeps running to ensure a permanent air circulation
for filtering the air, neutralizing possible odours and
monitoring the humidity level.
ð If the set humidity level is exceeded, the compressor will
automatically be activated to dehumidify the room air once
again.

adjusted from the minimum to the maximum value for the
standard permanent treatment.
Beyond that, an additional 5th level is available for short-time
intensive treatments.
When using this fifth setting, a small amount of ozone is
generated inside the device, however, if used as intended,
this concentration is neither a health hazard nor is it
damaging to the material.
Recommended procedure for standard treatment
(settings 1-4)
The perception of odours is subjective. Besides, fluctuating
climate parameters such as the humidity level and room
temperature influence not only the diffusion of odour particles in
the room, but also the reaction potential for the oxidative
conversion of airborne odours and pollutants.
For this reason it is not possible to specify a linear reference
value e.g. depending on the room size. Instead we recommend
an individual, active levelling geared to the local circumstances
and your personal requirements:
1. Before the first application, air the room out thoroughly.
2. To begin with, set the ionizer to level3 and the fan to
stage1 and let the device run with these settings for up to
7days.
3. During or at least at the end of the treatment there should
be either a perceivable reduction of the odour intensity
and/or a slight ozone odour.
If so, you can now turn the ionizer down by 1level and, if
required, repeat this step according to your odour
perception until you have reached level1.
4. If after a period of 7days you cannot observe a reduction of
the odour intensity or an ozone smell, increase the
operating level one by one up to max. level4 and treat the
room again for up to 7days. Before using level5 (intensive
treatment), first read the Procedure for intensive treatment.
Note:
• Any time you reduce or increase the setting by one level,
wait for at least 7days before making another change.
After every interval and before any level adjustment air the room
out exhaustively!
For the standard treatment the fan should be set to stage1.
Procedure for intensive treatment
In case of considerable odour nuisance – e.g. from long-lasting
sources such as drains, fuel odours or the smell of mould or
intensive one-time sources like tobacco, animal smells or musty
odours in the car etc. – and if the previously performed standard
treatment was not successful, it is appropriate to carry out a
short-time intensive treatment at level5 to effectively eliminate
the cause.
1. Make sure that all surfaces in the room to be treated are
freely accessible for the circulatory air of the DH-VPR+
(open windows, boot and bonnet of vehicles, open wardrobe
doors, shut the curtains to provide the best possible
effective surface). If possible, remove car mats and carpets
in the passenger compartment and boot and spread them
out on the floor of the garage. The better the air circulation
at the surfaces to be treated, the better the chances for a
successful odour elimination. To achieve optimum results,
the room temperature during the intensive treatment should
be in a range of 20 to 25°C. This generally serves to ensure
a diffusion of the odorous substances. During the intensive
treatment the room temperature must not exceed 28°C!
2. Set the ionizer to level5 and the fan to stage2 and let the
device run with these settings for 24hours.
3. After this treatment period set the intensity switch from 5
back to a lower level and see to a thorough 15-minute
ventilation (rush airing) of the room. The ozone smell is
usually evaporated after 2 to 3 intermittent ventilation
processes.
4. If after the 24-hour treatment the reduction in odour
intensity is not satisfactory, repeat step2 up to five times as
the circumstances require.
5. After a successful odour reduction repeat step3 and
continue with the standard treatment (levels1-4).
6. Also set the fan to at least stage1.
Small amounts of ozone are generated within the device during
the intensive treatment. In the room air the ionizer does not
produce ozone concentrations exceeding the generally
applicable limit values. For reasons of safety and due to
individual sensitivities however, there must be no person or
animal present in the room to be treated. Entering the room as
well as brief visits to switch the device on and off are as
harmless as the short-term exposure to the ozone smell that is
sometimes subjectively perceived as intense.
Note:
• If an ozone odour becomes noticeable in the room (not just
at the outlet opening) during the standard treatment,
gradually turn the intensity down until the smell is no
longer perceivable (Remember to air the room every time
you lower the intensity level).

Operating manual – dehumidifier / climate manager DH 30 VPR+ / DH 60 VPR+
Ozone smell
If used as intended and for appropriate room sizes in inhabited
rooms such as basements, garages, halls or libraries our ionizer
does not produce harmful concentrations exceeding the max.
allowable concentration at the workplace (MAC limit value) even
if set to the highest level(5).
And yet, even this low concentrated ozone odour is often
perceived as very disagreeable. The factor between the odour
threshold perception of 40µg/m³ and the valid exposure limit
values at the workplace based on the MAC value (maximum
allowable concentration) of 0.2mg (200µg)/m³ of room air
amounts to 5.
With ozone concentrations of as little as 40µg/m³ or slightly
above many a person perceives this ozone smell as offensive
and very disagreeable. Up to the MAC limit value variations in
the ozone concentration can hardly be discerned by way of
smell, which means that even with completely uncritical
concentrations the reek of ozone is distinctive.
However it also indicates that at the same time strong
odoriphores are being effectively neutralized, e.g. tobacco,
animal or mould odours diffusing from leather, textiles, carpets,
wood or other porous materials.
Room temperatures and odours
Also important for a successful application beside the correct
dosing is the temperature at which the treatment takes place.
Heat increases the rate at which odorous substances diffuse
from materials. Once the odour is in the air, it is bound by
oxygen.
If during the wintertime the room temperature is too low (below
12°C), the odour might come back all of a sudden in the
summer. Additional heating in the cold season helps to improve
the release of not yet diffused odour particles. Hence, the
correct temperature for an effective treatment is to be attained
by trial and error.
It is easily conceivable, that you only need to use the ionizer
after the winter season, when the fuel evaporation of vehicles
with carburettor increases, odours from textile coverings begin
to diffuse or else only after extreme precipitation periods, when
the basement begins to smell musty owing to the increasing
moisture penetration in the brickwork.
Individual odour perception
The odour perception and rating differs from one individual to
another.
Because of this individual perception, a general across-theboard recommendation for dosage and usage is not feasible,
therefore every user can only achieve his odour balance by
actively and patiently levelling out the intensity levels.
Whether it concerns the smell of mould in a vault cellar, fuel
odours in the garage or the musty smell in a historical library –
every person feels differently about it. Mostly, it is not the smell
per se that is regarded as bothersome, but the intensity.
Subtle smells, generally associated with the respective
collector's item, are often desirable and even perceived as
quaint – an automobile enthusiast for instance might just love a
whiff of gas in the garage whereas his wife will probably take to
her heels once a certain intensity is reached. For an oenophile
an old wine cellar may well smell a little musty and old, but
never foul. There are many other examples we could add to the
list.
To ensure an adequate efficiency of the device as well as your
individual satisfaction, active tuning of the intensity level over
several weeks bringing it closer to your personal odour balance
cannot be avoided.
An odour neutraliser is no odour improver
Nevertheless, you should always bear in mind that this device is
an odour neutraliser, not an odour improver as may be
commonly used for the active scent marketing in department
stores. Pure neutralization through the electrical oxidation or
chemical bonding of odours does not imply a subsequent
fragrance or pleasant smell in the air.
From experience: in some cases it is also possible that after the
successful neutralization of primary odours other smells, which
have previously gone unnoticed, become apparent and are then
in turn individually perceived as objectionable.
Odour is and will remain an extremely distinct issue greatly
influenced by the personal sense of smell and the perceptual
sensitivity.
With a device of the VPR+series you have chosen a
professional tool to improve the storage conditions for your
valuables.
We are not in a position to improve the existing state of
materials and objects, but, if applied correctly, our products can
contribute to their permanent preservation by protecting your
valuables from corrosion, dust, mould and bacterial
decomposition.

Ozone treatment for similar applications
A (highly concentrated) ozone treatment is carried out for
example in the professional car valeting. Especially in case of
pre-owned cars, unpleasant odours inside the passenger
compartment (e.g. former smoker's vehicle) can be eliminated
in this manner.
The oxidising effect of ozone turns odorous substances into
odourless substances. Germs and odour-causing bacteria are
killed in this process – even at otherwise inaccessible locations
such as under seats or in ventilation openings. As a result of this
treatment the vehicle is disinfected and usually odour-free.
The ozone treatment is also a worldwide standard method for
odour neutralization and disinfection in the hotel industry, used
in smoking rooms or for other substantial odour nuisances.
In the sector of fire, water and sewage damage restoration
ozonization has been the most commonly used standard method
for many years.
Employed for these applications are however pure ozone
generators with concentrations of 5g/m³ and more, which
cannot be compared with the NTPgenerator built into the
VPR+series.
Should you have similar requirements or be unable to get the
odour sources under control despite the application of the
VPR+ionizer, please contact our specialist consultants. We'd be
happy to advise you and we offer ozone generators of every
performance class for the professional odour neutralization. If
necessary, we will refer you to proven experts in your region.
Neutralization of fuels
Generally, the fuel odour in garages can be neutralized
sufficiently. Within 2weeks the objective of a sufficient
neutralization rate is usually achieved.
With extreme evaporation rates however (many sources of
evaporation, sports carburettor, leaky tank lines or gaskets and
high room temperatures) in some cases the neutralization
performance of the (or an) ionizer is not sufficient to produce the
desired success. An ozone concentration well beyond the max.
allowable concentration at the workplace (MAC limit value)
would have to be emitted in the room.
Leaving aside the fact that fuel vapours of this concentration are
hazardous to health, low-dose ionizers can solve this special
problem only in part.
In order to successfully eliminate such extreme fuel odours,
mechanical and chemical bonding of the vapours has to be
effected in addition to the electrical neutralization.
For this purpose we offer mechanical air cleaners that have
activated carbon filters specifically designed for extreme fuel
odours. Combined with the ionizer we achieve a satisfactory
solution in 99% of cases with extreme fuel odours. Often
another separate ionizer can also be helpful in such cases.
Please contact our consultants as needed.
Air filter
As standard, devices of the VPR+series are delivered with 2air
filters:
• 1 x air filter dust (standard)
• 1 x air filter dust/soot (combination filter)
The technical data given for the air volume freely blowing refers
to the air volume at the device outlet without filter. Every air
filter applied reduces the amount of circulated air depending on
the type of filter and its filtration efficiency.
All filters are adapted for the devices of the VPR+series and
work together perfectly.
Owing to the more efficient 2-stage filter ladder, the dust/soot
combination filter reduces the amount of exhaust air to a greater
extent than the standard air filter. The circulating air
performance depends on the contamination level of the
combination filter: with a new air filter it is reduced by 15%, if
the filter is heavily contaminated with soot the circulating air
performance will be reduced by up to 99%. Soot contains oily
products from incomplete combustion and clogs the filter
surface excessively – especially when combined with the dust
from the room air. On these grounds and in case of a high dust
and soot pollution it is especially important to regularly check
the air filter for dirt and to replace it if necessary.
The two stages of the fan permit an individual adjustment of the
circulating air performance to the respective room size and
odour nuisance. The selected filtration method must be
observed, since the attainable air flow rate varies depending on
the used filter type (standard or combination filter). The table
below contains the model-specific air flow rates for the fan
stages1 and 2 including all filter combinations:
DH30VPR+:
Fan stage Freely blowing Standard filter Combination filter
Stage 1 502 m³/h 455 m³/h 420 m³/h
Stage 2 745 m³/h 685 m³/h 635 m³/h
DH60VPR+:
Fan stage Freely blowing Standard filter Combination filter
Stage 1 745 m³/h 675 m³/h 590 m³/h
Stage 2 1,065 m³/h 985 m³/h 900 m³/h
In garages with modern vehicles, where corrosion is of minor
importance, in museums, libraries or wine cellars, thus all
rooms in which the emission of soot can normally be ruled out
and where the prevention of mould and bacteria is paramount, it
is advisable to use the standard air filter. The standard air filter
has less impact on the reduction of circulated air volume than
the combination filter. Consequently a higher air circulation is
achieved when using the standard air filter. Albeit, for the filter
change the same rules apply as for the combination filter.
A dirty air filter significantly reduces the dehumidification
performance, the equipment's lifetime and the efficiency of
odour neutralization.
