Safety Features

Supervisory Safety Monitoring System has been introduced for additional Safety measures. Individual additional micro – controlled is used for this supervisory system. If the temperature value crosses set Hi & Low limits for either or both parameters, safety control action will be taken over by this controller. If the parameters sets within the limit value, main control action will resume automatically.

ELCB, MCB for Compressor, Air heater & Mains.

2 Min. Compressor ON delay time for safety of compressor

Special Care

Suitable K.V.A. Servo Controlled Voltage Stabilizer is strongly recommended.



To comply with the documentation requirements, we provide IQ, OQ & PQ protocols to be executed before taking the chamber in to for regular use, and support the supply with the following documents with the detail operational and service manual.

Standard Operating Procedure (SOP) Operational Manual for Controller IQ,PQ,OQ protocols certificate. Calibration certificate of all controlling modules with traceability.
Certificate of MOC. Test Report of chamber prior to supply with mapping certificate. wiring diagram for ease of service maintenance.

Refrigeration System

A hermetical sealed compressor with CFC free refrigerant & optional stand by refrigeration system for uninterrupted operation. The both system can be operated alternately for a certain period, thus increasing the life of the system & In case of break down the alternate stand by system can be
operated for uninterrupted services.
