Overview

Purpose & Application

The ENV-01-2 chamber executes both temperature cycling and steady-state regimes within the specified envelope. Ramp rates between 1 degC/min and 10 degC/min are supported as average or linear profiles. Single-stage refrigeration is used down to -40 degC; cascade refrigeration runs below -40 degC. Selectable Eurotherm 2604 or PLC-HMI program controllers enable complex multi-segment cycles for IS 9000, JSS 55555 and MIL-STD-810 testing.
