Most walk-in chambers are limited to 85°C or less, but EWS “solid” models can go to 150°C to accommodate extreme test conditions. Also desirable for temperature-cycling faster than 10°C/min.
EWS chambers are solid, one-piece construction, using fiberglass insulation and an angle-iron frame. The stainless steel interior liner is reinforced and continuously welded, including leak-testing for integrity. Conventional chambers (like our EWP models) are built using panels with foam insulation that cannot withstand higher temperatures and are more susceptible to leaks at the seams under extreme conditions, such as fast temperature cycling.
The angle-iron frame provides enough structural strength to allow a full-opening door for easy loading of large arrays without restriction. A full-opening door can also allow floor-space saving over panel chambers.
Overall temperature range:
-65°
85° Conventional panel chamber
-65°
150° EWS solid chamber
Allowable temperature change rate:
0°C/min.
10°C/min. Conventional panel chamber
0°C/min.
15°C/min. EWS solid chamber
Note: Actual change rate capability is determined by selection of heating/cooling system based on your requirement.
