Climate chamber THR

thermostatictemperaturehumidity

Overview

Product summary: ASLI walk-in climate chambers (THR Series) provide large-capacity environmental test space for whole-product aging, reliability and combined temperature–humidity tests. Available as modular foam-panel assemblies or fully welded solid rooms to suit site, thermal load and change-rate requirements.

Drive-In climate Chambers (THR Series) — key capabilities

Key capabilities: Integrated piping and ducting, touchscreen controller with PLC, configurable room dimensions to match DUT and lab layout. Commonly used in electronics, automotive, LED, PCB and home-appliance testing where whole-product exposure and cart access are required.
