Environmental Test Chamber


The exposure to sunlight can damage your product, decrease its performance and shorten its life; so it is crucial to understand in advance which would be the reaction to solar, humidity and temperature variation.
If your product during its life will be exposed to this phenomenon, ACS solar radiation test chambers are the right solution: they have been designed to understand the specimen reactions in its normal context of use.
Performance, insulation, noise, resistance to physical and mechanical loss are some of the investigated parameters.
The ACS Solar Radiation chambers is a wide product range, available in basic version, energy saving and 5 K/min with different volumes, to fit the customer's needs.
The lamp structure is made of anodized aluminium, while the assembly components are made of stainless steel.
The percentage of the lamp intensity can be adjusted using the touchscreen control panel, it takes approximately 3 minutes to reach the requested output.
We provide a plug for the chamber interior; it can be easily removed and/or installed to use the chamber in standard configuration, without the solar lamp.

general features

Solar lamp
The lamp structure is made of anodized aluminum and the assembly components are made of stainless 
The percentage of the lamp intensity can be adjusted using the touchscreen control panel. It takes approximately 3 minutes from the moment the lamp is turned on for it to reach the requested output.

Internal chamber plug

The internal chamber plug is easy to remove and/or install and makes it possible to use the chamber in its standard configuration without a lamp.

Porthole cover panel

An easy to remove and/or install inspection porthole cover panel is provided for installation in the chamber door.

Electrical power system (EPS)

This unit provides a permanent regulation of the power output. The irradiance selected will therefore be stabilized by means of voltage and current parameters. This device is positioned on top of the chamber.


The light bulb is easy to change thanks to the handy clamps provided.

Control and management system and interfaces

Controlled by PLC and Advanced HMI

Remote access

There is a wide range of possibilities thanks to the built-in MyKratos™ and MyAngel24™; multichamber control also available upon request.

Electromagnetic closing system

Ensures the security of environmental tests.

Air treatment system

Ensures a precise control of the climatic parameters inside the chamber with minimal thermal inertia; an axial fan allows rapid temperature variations of both air and specimen.

Humidification system (only climatic version)

The humidifier with a self-contained heater and dedicated controlling S/W offers two great advantages:

  • it does not require distilled or demineralised water to operate properly
  • it uses ‘dry’ vapour in order to avoid condensation on the specimens and to reproduce real environmental conditions

air treatment system

System includes the following components:

  • Cooling evaporator
  • Heating system
  • Dehumidification system (only climatic version)
  • Thermoregulation air circulation fan
  • Temperature and humidity probe


Mechanical cooling based on single stage system (-40°C) or cascade systems (–70°C). The cooling system is realized with semi-hermetic alternative type compressors including an automatic injection-type protection system. This protects the compressors when they are cooling down from high temperatures.


The chamber is heated by means of electrical heaters, protected by safe thermostats that disconnect overall chamber main power components (such as compressors, fans and heaters) in case of accidental over-temperature.

humidification and dehumidification (climatic models)

Direct humidification occurs through an electrical vapour humidifier.
The chamber is equipped with a water storage tank (about 18 l capacity) and a water connection on the back of the chamber for automatic refilling.

There are three ways to ensure the water supply needed for any kind of climatic tests:

  • Connecting the chamber to normal tap water network by means of suitable water connection
  • Manually refilling the tank with demineralised water
  • Connecting the chamber to demineralised network

In order to reduce water consumption, water recycling can be activated through a button on the control panel (only possible when the specimen does not contaminate the water during the test).
Dehumidification is performed by the condensation cooler (dew point cooler) directly connected to the refrigeration circuit. This principle permits high stability of parameters in conjunction with energy-efficient dehumidification.

humidity control

Temperature Measurement with Pt100 thermal probe Class A, max precision 0,3K.
Relative humidity measurement with Assmann psychrometric system complete with Pt100 thermal probes. The psychrometric principle (dry & wet bulbs) is used for the measures in the test chamber. This allows the set and measurement of relative humidity expressed directly in % R.H.
Relative Humidity range from 10% to 90% within the temperature range [+10°C; +90°C], in standard configuration (without solar lamp and with internal cover). 

  •          AREA 1, Range without radiation (with covers), DEW POINT(A)(B) +5 ÷ +87°C
  •          AREA 2, Range with radiation, DEW POINT(A)(B) +5 ÷ +71°C

The values refer to the basic version at room temperature of +22°C, with temperature and humidity measurement made in the air inlet.

 NOTE (A) Performance measured at room temperature of +22°C and empty working space

NOTE (B) Dew point temperature range (for continuous tests) only for climatic chamber


The chamber is equipped with a PLC (Programmable Logic Controller) for managing all the chamber’s functions and safety interlocks. The HMI system consists of a 10'' on-board panel and a remote control via mobile and desktop devices. MyKratos™ software (including MyAngel24™ Interactive Assistance System), is available both from the on the on-board panel and remote devices with the same user-friendly graphical interface. 

On-Board Panel: 10'' Touch Panel, 16 M colours with a touch menu with related pop up screens, allowing the control of all the chamber functions.
