Description
Temperature test chambers focus on the required temperature simulation test from 4 optional low temperature -70 °C; -60°C; -40°C; -20°C to high temperature 180 °C.
Chambers with Single-stage Refrigeration systems are capable of achieving workspace temperatures down to -20°C. This is fine for many commercial and industrial tests that require low temperatures of typically 0°C, -10°C or -20°C. A single-stage system uses one compressor to directly cool the workspace.
Chambers with Cascade Refrigeration systems are capable of achieving workspace temperatures down to -40°C~-70°C depending on model. This is required for many ruggedized industrial, automotive and military test procedures that require low temperatures of typically -40°C, -55°C or -65°C. A cascade system uses two interdependent compressors.
