Customised "Walk-In" Chambers

Walk-In chambers have been developed for special applications, when the need of performing climatic tests on complex, sometimes huge equipment (cars, refrigerators, computers, and telecommunication systems) arises. Walk In chambers are usually tailored to suit the specific customer's requirements with the help of the versatility and high-technology levels achieved by ACS in the field of environmental testing.

Walk In chambers can be divided according to the four different climatic systems used, those temperatures range from -70°C to + 120°C (R.H. range: 10%-98%)

• Air-evaporator system for low performance chambers operating at fixed climatic parameters
• Reach-In systems with external air treatment for standard climatic cycles
• System with internal air treatment for high performances (fast cycles)
• ACS - patented indirect system used for explosion-proof high precision tests for humidity control in the presence of high dissipation

Features:

• Sandwich panels with interior in AIS304 stainless steel and insulation obtained by means of ecological materials
• Different door versions available: side hung, sliding,swinging, motor driven
• Pressure regulation by means of digital vacuum-meter
• Self draining floor (ACS patented) for the automatic drain of condensation
• µPLC-based control and management system with users interface ( to be chosen between keyboard and display or PC and dedicated software)
• High flexibility in the supply of special accessories upon customer request
• Air flow optimization system by means of fluido-dynamic devices aimed at making the climatic conditions inside the test compartment uniform

UC31-5080 IND

Walk In Chamber for Telecommunications

• It can simulate the environmental conditions, including high low humidity, to which is subjected a radio base station dissipating 5KW.
• The cooling is performed through a single phase indirect system.
• Capacitive and pt100 probes are used for the measurements in the test chamber, allowing an extremely precise control of the programmed values.

Rolling Bench

• The system is used to check efficiency and performance of the complete car under climatic stress during the typical cycles defined by automotive norms.
• The tests require to run the engine and to interface the wheels with road simulator systems (rolling benches) in order to drive the vehicle at various speeds.
• An air pressure regulation system provides the pressure balance of the exhausted gas in order to ensure a correct working of the car engine.
• To check the vehicle emissions a hydrocarbon system is installed.

Walk In Chamber for Accelerated Corrosion Test

• It has been specially designed and manufactured for the Electricité De France.
• It is a very large chamber, 700 m3, for accelerated testing of external High Voltage Insulators (300 KV).
• The system includes temperature, humidity, salt fog, rain and solar simulation.
