CLIMATIC (ENVIRONMENTAL) CHAMBER

Salient Features

• Heat proof and electrical shock resistant design
• Automatic cycle commencement on press of a button
• Digital display of humidity and temperature data
• Ramp & soak profile controller
• Capacitance type Humidity sensor enables direct display of RH and temperature
• Highly ergonomic door handle with unique key lock

Heating system

Easily removable U-shaped jacketed air heaters connecting with Teflon wires. Interlocking for preventing the operation of heating system without air circulation. The heaters will be placed in the conditioning plenum such that there is no direct radiation from the heaters on to the test specimen.

Refrigeration system

Air-cooled semi sealed refrigeration system. Ozone friendly refrigerant. The system is provided with adequate safety protection against excessive and low pressure and temperature. Pressure gauges provided to indicate suction and head pressure. HP/LP cutoff switch and overload protection for the system. Oil separators with oil return & hot gas defrost system. All refrigeration components like expansion valve, driers, oil separators, pressure gauges and vibration eliminators provided. Reputed company make like Danfoss - Denmark, Wika - Germany.

Door & Gasket

Robust type hinges fitted on the right hand side of the chamber with front opening single door.  Leak proof double lined silicon gasket will be provided. The inner surface of the door will be provided with pre - polished stainless steel and will be mounted such that conduction is avoided.

Viewing window
