Description

Description

Walk-in test chamber is an ideal chamber for large or irregular shaped test objects and for fast temperature change rates, high humidity and explosion resistant applications.

Product Features

Double door easy access design

Setting or program operation modes

Standard water cooled cooling mode

Single-stage or cascade stage refrigeration system with semi-hermetic compressor

Balanced temperature and humidity control system

A combination of control panel, electric switchboard, insulation board, forced fan, heater, humidifier and refrigeration unit

Mainly 7 standard room sizes of 28 different test specifications

Refrigerator uses original Europe/America compressor and CFC free refrigerant

Refrigeration system adopts cascade low temperature circuit design

Integrated board units for easy assembly and disassembly

Shell is made of high quality stainless steel (SUS304). Solid, waterproof and elegant structure

Multiple wings air supply mode and the horizontal diffusion and ventilation heat exchange circulatory system keeps interior chamber temperature and humidity uniformity

When an exception occurs, controller screen will automatically display fault status in real time, cut off the power supply switch and provide troubleshooting techniques

Doors and chamber uses dual-layer insulation gasket to ensure chamber sealing quality
