High & Low Temperature Series

Rapid Temperature Change Test Chamber

Rapid Temperature Change Test Chamber

Features

• R404A and R23 environmentally friendly refrigerants with zero ozone damage are used.

• All pipeline welding is protected by nitrogen gas to ensure that the inside of the pipeline is not oxidized, and the surface of welding joint and pipeline is coated with anti-corrosion protective layer.

• Using intelligent microcomputer PID+SSR and FUZZY control, the control accuracy is stable and precise, which can fully meet customer test requirements.

• The multi-blade blower is used for strong air circulation to avoid any dead angle and ensure uniform distribution of indoor temperature and humidity.

• The box circuit system, water system and refrigeration system are modularly distributed to ensure safe and reliable operation.
