Thanks to ACS Air Conditioning Unit Chamber, it is possible to simulate the desired temperature and humidity inside the chamber and push the moisture into an external testing unit.
The chamber can operate in either stand-alone mode, in which the chamber functions autonomously with its temperature and humidity control, or in remote unit mode, where the chamber acts as an air conditioning generator.
The chamber models indicated in the table below can be provided in Air Conditioning Unit configuration:

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 circulation system:
This system is equipped with an air circulation fan that draws air from the chamber environment and sends it to the external unit.
Flexible hoses:
The flexibility of these hoses allows the customer to position the external unit according to his needs; their insulation guarantees optimal performance.
Service panel:
The system is equipped with a PT100 temperature probe that can be moved to any area of the external unit, and an electronic chamber alarm thermostat.
System includes the following components:
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.
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:
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.
Temperature Measurement with Pt100 thermal probe Class A, max precision 0,3K.
Relative humidity measurement with Assmann psychrometric system complete with Pt100 thermal probes.
Relative Humidity range from 10% to 95% within the temperature range [+10°C; +90°C].
The values refer to the basic version at ambient temperature of +22°C, with temperature and humidity measurement made in the air inlet.

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 an on-board panel (Keykratos Evo) and a remote control (MyKratos™ including MyAngel24™) connected to the chamber.
On-Board Panel (Keykratos Evo) consists of 3.5 inch Analog Touch Panel 65,536 colours with a touch menu with related pop up screens, allowing the following activities: main chamber's parameter setup, manual control, possbility to start the last stored profile, visualization of eventual alarm notifications.
MyKratos™ control software makes it possible to manage, monitor and assist the chamber anywhere, at any time, in multiple ways (Wi-Fi, Ethernet, mobile network) via mobile and desktop devices. The chamber wireless (Wi-Fi) connection permits operation using tablets and smartphones (iOS 8 or Android 4.2.1 compatible). The operator interface can also be remotely accessed through a chamber connection to the client’s LAN or via mobile network (on activation of SIM card data). It includes the MyAngel24™ remote-assistance system.
MyAngel24™ is an online diagnostic and remote servicing system included in the chamber basic configuration, activation is possible on Customer demand. Once activated, Angelantoni Server acquires data coming from the chamber, allowing ACS Service Staff to grant a remote assistance 24h.
ACS service staff can identify the problem and if possible, solve it remotely, or at least identify parts that may need to be replaced and check their stock availability in order to schedule an utmost efficient on-site intervention.
