MORE THAN TECHNOLOGY
Foreword
You are about to choose an environmental
test chamber that will meet your test requirements. Technically perfect, equipped with
long-life silent compressors, it guarantees
years of trouble-free, reliable performance.
Perhaps you already possess one or several
chambers that are working fine, but you may
have complained about excessive noise, bad
humidity control and condensation, slow
temperature/humidity variations, unbalanced
air distribution inside the chamber, complicated programming systems. These can be
the results of a hurried, somewhat superficial
choice.
So now take your time and let us introduce
to you the 3
rd
generation of HYGROS
®
chambers and the new CHALLENGE MY05
series chambers. We believe that they will
turn out to be a valuable investment over
time and will help you to carry out repeatable, comparable environmental tests.
How to choose
an environmental
test chamber
There are several factors influencing the
choice of a good chamber:
standard manufacturing processes allow-
ing short-term deliveries
hermetically-sealed, silent compressors
using ecologically friendly refrigerants
air temperature variation and quick adap-
tation of specimens to it
innovative design, whose impact is particu-
larly important in modern laboratories
a wide range of accessories, both optional
and standard
friendly, flexible, up-to-date control and
management systems.
HYGROS
®
e CHALLENGE MY05
chambers
After analysing the factors determining the
choice of a good chamber, try and identify
among the new HYGROS
®
and CHALLENGE
MY05 chambers (59 models for every family!)
the one that best suits your test needs. HYGROS
®
and CHALLENGE MY05 chambers
have been actually designed and produced to
fulfil all your expectations ...and possibly more.
Why
We have been manufacturing cooling equipment since 1932. We have been producing
environmental test chambers since 1952
and our export - more than 80% of our total
production - places us among the largest
manufacturers in Europe.
In addition, we are among the three world
leading companies in the field of space simulators (working down to 10°K, that is down
to –263°C!).
The acquired ‘know-how’ has helped us to
achieve important goals throughout the
years and today our staff and ideas are perfectly tuned to customers’ needs. More than
600 employees working in 7 production and
commercial units are constantly studying the
right solutions, developing new ecological,
smart, innovative-design test equipment for
you.With the future in mind.

AND CHALLENGE MY05 CHAMBERS:
B
ORN UNDER THE SIGN OF TOT AL QUALITY
All HYGROS®and CHALLENGE MY05
chambers are manufactured following the
principles of Total Quality , according to the
ISO 9001 and ISO 14001 standards.
HYGROS®and CHALLENGE MY05 chambers:
environmental protection
Our refrigeration systems only use those refrigerants that have not been forbidden by
the Convention of Montreal and by the London and Copenhagen amendments (R404
a, R23).
New-concept CFC-free polyurethane foam has been used for thermal insulation since
it ensures, unlike glass wool, stable performance over time.
All connections and welding in the refrigeration systems have been carefully checked
by means of helium leak detectors (mass spectrometers) to ensure perfect seal.

1 Heated inspection window: a fully-
transparent double heating film allows the
test compartment to be easily and clearly
inspected and prevents condensation from
forming on the glass (optional on CH).
2 Control system: consists of a µPLC and PC
interface with Kratos SW (Hygros) or touch
panel (Challenge). In 5 languages (Italian,
English, French, German, Spanish), it allows
a perfect interaction between the equipment
and the user.
3 Double ceiling: prevents any condensation
drop from falling onto the specimen.
4 Dehumidifier: operates down to –20°C dew
point.
5Centrifugal fan: reaction-type , it allo ws a
better distribution of air and helps specimens
adapt to temperature variations.
6 Interfaces: RS232 or RS422.
7 No. 6 analog inputs + no. 4 inputs for PT100
probes (Hygros).
8 Digital min./max. thermostat: in case of
malfunctioning, the specimens under test
may be disconnected.
9 Humidity: open/close circuit for
humidification water complete with
mechanical filter.
10 Wheels: they allow the chamber to be easily
moved
11 Rounded corners: they allow a better
drainage of condensation drops and easier
cleaning.
12 Water tank:for the humidification system, it
is accessible by simply opening the lower
door of the chamber.
13 Humidification system:it is fed with normal
running water.Dry-vapour-type double
generator to prevent condensation from
forming onto specimens.
14 Double pump:it allows the recycling of the
water needed by the humidification system.
It is equipped with a protection device in
case of water shortage.
15 Innovative design in two different colours:
standard RAL 5015 and RAL 7035.
16 Double floor:it improves the distribution of
air inside the chamber.
17 Front panel in plastic material: to reduce
the chamber weight and to ensure better
endurance to corrosive agents.

The new range of climatic chambers (temperature and humidity control) and thermostatic
chambers (temperature control only, marked
with the suffix T) offers 66 (sixtysix) basic
models whose nominal capacity varies from
16 to 2000 litres.
These chambers may be divided into two families: HYGROS
®
(H) and CHALLENGE MY05
(CH) chambers, both available in the following
versions: with single-stage compressors
(–40°C minT) and with cascade compressors
(suffix C, –75°C minT). The two models basically differ according to the user’ s interface:
• equipped with PC with front monitor for
HYGROS
®
chambers;
• touch panel for CHALLENGE MY05 cham-
bers.
Control and management system:
µPLC-based, it allows chambers to be
managed completely through analogue
and digital interfaces.
Chamber lining:
stainless steel with vapour-proof welding (all models).
Drip cap:
invisibly placed under the door, it is extremely efficient.
80mm port hole:
available on all models.
Noise reduction system:
installed in the machine compartment, it
reduces the chamber noise (59 to 68 dB
according to the compressors size).
Further noise reduction may be provided upon request.
Double ceiling and double floor:
they allow a better air distribution inside
the chamber avoiding condensation or
dripping over the specimen.
Air treatment system:
it ensures a precise control of the climatic parameters inside the chamber
with minimal thermal inertia; a powerful
reaction-type fan allows rapid temperature variations of both air and specimen.
Refrigeration system:
simple and reliable, it ensures optimum
thermodynamic performances at any
temperature.
Network connection:
several chambers may be connected to
a master PC for both local and remote
centralised supervision, storage of test
cycles and data logging.
Structure:
the equipment modularity allows easy
servicing and upgrades.
Ergonomics:
it allows easy access to the chamber
wherever placed; the control interface is
mounted on the front panel; the water
tank is easily filled from the lower front
panel.
Design:
all protrusions have been carefully eliminated in order not to break the purity of
the chamber style.

Humidification system (climatic version):
it offers two great advantages:
• correct functioning without the need of
distilled or demineralised water;
• the use of ‘dry’ vapour in order to avoid
condensation on the specimens and to
reproduce real environmental conditions.
Humidity control (climatic version): the
principle of the Assman psychometer (dry
bulb - wet bulb) was applied to allow the
microprocessor to correctly determine relative humidity and setting parameters.
For low-humidity continuous tests, a control system equipped with a capacitive
probe is also available.
*For temperature only versions
(without R.H. control) add the
suffix T .
Example: H250 T (–40/+180°C)
with 224 litres capacity; H1200
TC (–75/+180°C) with 1152
litres capacity
➀ Without wheels (when wheels
are mounted, from 50 mm to
70 mm must be added to the
chamber height)
