2. Set-up

2.1 Air-tight housing

The housing of the ComfoAir XL has a unique quality.
The double seals on the panels ensure that the
housing is perfectly air tight. The housing comprises
a self-supporting structure that is made from double­walled panels with internal insulation that is 44 mm
thick. The panels are produced from sendzimir sheet
with a weatherproof Plastisol coating (Goosewing
Grey – RAL 7044) applied to the outside. A special
polyester coating (RAL 7035) is applied to the inside.
These panels are free from thermal bridges and
guarantee excellent insulation of the housing. The
draft focusses on compliance with the Passive House
Directive (internal and external leaks lower than 3 %).
An overview of the specifications is provided below.

2. 2 Fans

The ComfoAir XL series consists of directly driven,
energy-saving EC fans with backward-curved blades.
These fans achieve an energy saving of more than
25% compared to conventional AC fans. These fans
are mounted vibration-free onto a mounting bracket.
This obviates the need for flexible sleeves to ensure
a vibration-free connection of the air ducts.

Error message

An alarm function is included in the control board as
standard. This alarm function is activated if a fan
fails. The error message can also be activated by
measuring the pressure difference via the supply air
filter if desired.

2.3 High-performance plate heat
exchanger

The HR cross-counterflow heat exchanger (HR plate
heat exchanger) is made of high-grade aluminium
and has a thermal efficiency of approx. 90 %
depending on the outside temperature and the air
humidity in the rooms. The exchanger is corrosion­free and resistant to seawater and can be fully
recycled.

Benefits of a high-performance plate heat exchanger:

■ No wear

■ Easy to maintain

■ 100 % separate air streams

■ Low risk of contamination

Frost protection

Under certain circumstances, condensate can freeze.
To prevent this, frost protection is incorporated. This
shuts down the supply fan when there is a risk of
frost and can deactivate it for a short period.

2.4 Siphon

A siphon is installed to remove condensate that
forms in the plate heat exchanger.
An external diaphragm siphon must be connected to
remove the condensate that forms on the cooler. The
siphon can be kept frost-free by using an insulated
ribbon heating element. The contact for supply and
control can be set in the software.

2.5 Bypass

ComfoAir XL is equipped with a 100 % bypass. The
control unit of the ComfoAir XL automatically brings
the bypass valve to the closed and open positions.
This bypass is located near the heat exchanger and
is controlled by a counter-rotating bypass valve,
which is controlled automatically by a servo motor.
When the bypass valve opens, the extract air flows
around the high-performance plate heat exchanger
and no thermal transfer takes place. The filter system
continues to work, however. In this way, it is possible
to use what is referred to as 'free cooling' or night
ventilation in the evening and during the night.

Please also refer to the block diagram in chapter 1,
section 4 for details of bypass operation.

Supply air

Open/closed or modulating bypass

ComfoAir XL can be equipped with an open/closed
or modulating bypass. The servomotor regulates the
modulating bypass and ensures that the temperature
of the supply air is constant. This is particularly
important when the unit has a cooling battery.

2.6 Filter

Two types of filters are available for filtering the
supply and exhaust air flows: one cellular filter and a
bag filter. The supply air flow is equipped with a F7
filter as standard, the exhaust air flow is equipped
with a G4 filter. With the newly developed filter
clamps, the filters are mounted onto the filter frame,
which minimises leaks. The units are equipped with a
filter monitor as standard. This is achieved with
pressure sensors that measure the resistance via a
filter to issue dirt notification.

7

2.7 Batteries

The ComfoAir XL series can optionally be equipped
with a pre-heater and post-heater or cooler.
The battery connections are attached outside the
unit. The control unit for these batteries is set up to
be equipped with several power relays (230 V) and
0-10-volt outputs via the connection board of the
unit. The connection board issues a 0-10 V signal to
control the two-way valve. The power relay (230 V) is
used to supply the circulation pump.
The batteries must be connected to an externally fed
cold and/or hot water supply. All batteries must be
selected on a project-related basis.

Pre-heater

A pre-heater can be attached to
pre-heat the cold outside air in winter.
This heating battery is positioned in
front of the heat exchanger and can be
used as a frost protection system. The
preheater is calculated on the basis of
the water/glycol medium to prevent the
battery from freezing.

Cooling battery

A cooling battery is used to cool
the supply air. This battery is
positioned behind the heat
exchanger like the post-heater.
The cooling battery is mounted on
the drain plate to collect
condensate. A polypropylene
droplet catcher that runs to the
drain plate is positioned behind
the cooling battery in the direction
of air flow.

2.8 Flaps

Flaps can be used to protect the unit
against outside influences when it is
not in operation. The intake can be
equipped with a lockable flap either
for the outside air or the exhaust air.

Post-heater

The post-heater increases the
temperature of the supply air. In this
way, air can be blown in at a higher
comfort temperature. The post-heater
is located behind the heat exchanger
in the direction of the air flow.

SAG 0-3V

ComfoAir XL keeps the air volume constant. Output
can be programmed in three air volume stages via a
display. The SAG 0-3 CV switch can then be used to
select the stages high, medium and low.
The housing is white (RAL 9010) and ideal for
installation in a fitted housing with a depth of 40 mm.
A surface-mounted housing is available for mounting.

CO

sensor

2/s

ComfoAir XL can also be controlled using a CO
sensor. A CO2 sensor measures the CO2
concentration in the ambient air at the position to
which it is attached. The CO
vent stage on the basis of the ventilation requirement
in the room. If the CO

2

ventilation stage is increased automatically. If the
CO

concentration is low, the ventilation stage is

2

reduced automatically.

Diaphragm siphon

A diaphragm siphon does not have a gooseneck;
instead it comprises a non-return valve made of
silicone rubber, which opens as soon as water
presses against the membrane and closes again due
to the vacuum in the unit. The siphon can be
equipped on request with a heating cable to protect
against frost or the formation of ice.

Siphon heater

Siphons are sensitive to frost. Siphon heating
reduces the risk of frost damage.

Joining piece

All units are delivered with rectangular connections
and tubtaras. They can be used to connect a drain
from rectangular to round.
