Temp & Humidity Series

Walk-in Constant Temperature & Humidity Room

Walk-in Constant Temperature & Humidity Room

Features

• The walk-in constant temperature and humidity chamber is mainly composed of a control panel, a switchboard, a thermal insulation board, a blower, a heater, a humidifier, and a freezer.

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

• Convenient and fast automatic water supply system, filtered by reverse osmosis pure water machine, automatically replenishing humidification water without manual operation.

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