Overview

Purpose & Application

The ENV-01-1 chamber is engineered for hot and cold steady-state testing at any set point within the rated range. Single-stage refrigeration is used down to -40 degC, while cascade refrigeration handles temperatures below -40 degC. The chamber meets virtually every national and international environmental specification used by Indian Defence, Aerospace, Space and electronics laboratories.
