The useful life of the products and their components could be affected by solicitations received during the packaging phase, transportation and depot operations in general which could determine a failure caused by arising defects not visible or predictable in the production phase. Moreover, the environment in which the products «operate» is affected by sudden temperature variations, which often generate quality problems. ACS, thanks to its wide experience, has developed a huge range of products to test different type of specimen on different application fields, to detect unpredictable future defects and to verify the specimen behaviour under controlled temperature and humidity variations.
E-Eco series The Discovery ”E” series chambers have the essential environmental chamber performances and are specifically designed for general purpose applications where extremely high temperatures or fast ramp rates are not required. The “E“ series is ideal for climatic tests at steady states. It is ideal for a wide range of applications such as Tropical tests on Pharmaceutical products, and for wide range of tests in the plastics, rubber, paper and semiconductor industries.
ES-Environmental Screening series The Discovery “ES” series now has even more environmental performance, whilst maintaining the same footprint and volume of the lower specification versions. Discovery “ES” has been designed for Environmental Stress and is ideal for reliability growth processes where temperature changing rate of 5 Degrees a minute are required. All of the chambers in the “ES” range are equipped with air condensers, except for the 340 l model where water condensation is required to maintain a compact foot print.

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
MyKratos™ and MyAngel24™: top of the line HMI for remote control
Inspection window: multiple-crystal, with double heated transparent film, 550h X 450 mm size
Self feeding system (tap water through chamber embedded softener)

AIR TREATMENT SYSTEM
System includes the following components:
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.
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 98% within the temperature range [+10°C; +95°C].
Dew Point range:
AREA 1, from +4°C to +94°C for continuous tests
AREA 2, down to -3°C for limited periods based on starting conditions and foreseen testing time
The values refer to the basic version at ambient temperature of +22°C, with temperature and humidity measurement made in the air inlet.
CONTROL SYSTEM AND USER INTERFACE
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.
