Insulation:

70mm polyurethane insulation (PUF)/ fiberboard to ensure better insulation and less leakage of temperature or RH from inner body to the surroundings.

Air Circulation:

Temperature is maintained by a quiet running blower circulation air throughout the chamber. Forced air circulated vertically down and re circulated throughout the chamber for uniform temperature and humidity.

Humidity:

Humidity created by steam injection method. The boiler tank is fitted in the back side of the chamber for better servicing, Electromagnetic switch for controlling the wet heater from burning off if water level is not adequate. Float valve provided to control water level in the boiler tank. 

Heating & Cooling System:

1. Long lasting SS tubular heaters used as heating element. The stainless steel fins provided to ensure better heat transfer.
2. Hermetically sealed compressor CFC free compressor (134 A gas) coupled with evaporation coil and condenser.

Trays for samples:

1. Removable Wire Mess/Perforated/S.S. Rod trays
2. Capable to with‑stand heavy load of test specimens
3. Such trays also facilitates better air circulation
4. The distance between trays will be 15‑20 centimeters

Control:

Microprocessor based Digital Auto‑Tune PID temperature and direct RH digital controller. Humidity directly measured in % RH by electronic sensor.

Safety Features:

1. High temperature safety cut off
2. Low water level boiler cut off
3. Electrical overload cut off
4. Time delay for compressor switch ON
5. Electrical circuit breaker
