High And Low Temperature Alternating Test Chamber

Equipment Function Summary:

The equipment is suitable for the electrical and electronic products, other products, parts, materials and various electronic components for high and low temperature test, low temperature and storage.

Equipment Construction:

The equipment is mainly consist of chamber, water cooling system, heating system ,air circulation system and control system.

The insulation system uses superfine glass fiber or hard polyamine fat foam to fill the insulation area to ensure the internal temperature of the box.

Independent heating and cooling system makes the equipment more effectively improve the heating, cooling, efficiency.

The refrigeration system is an automatic control and safety protection coordination system.

Adopt multi-wing powerful air supply circulation to avoid any dead corners and make the temperature distribution in the test area uniform.

Air circulation air return air design, wind pressure and wind speed are in line with the test standards, and can make the door instant temperature return time fast.
