Manufactured using quality tested mild steel sheets with three coats of paints; the Environmental Test Chamber has reliable performance. We are reliable Manufacturer, Exporter and Supplier of Environmental Test Chamber from New Delhi, India. The offered Environmental Test Chamber is double walled and the interior chamber is insulated with 150 mm thick glass wool and puff insulation all around for limiting the radiation within the chamber only.

Construction

• Chamber : Double Wall
• Exterior Chamber : Made of 18swg CRC MS sheet with three coats of paint OR 18swg Stainless Steel Sheet 304 grade.
• Interior Chamber : Made of 18swg Stainless Steel Sheet 304 grade.
• Insulation : The Interior Chamber is insulated with 150 mm thick glass wool and Puff Insulation all around for ordering to limit radiation.
• Door : A full front opening door, double walled insulated and interior lined with Stainless Steel will be provided for ensuring full access to the working space inside the chamber.
• Gasket : Two gaskets, one on the chamber and the other one for leak proofing at the door, are fitted.
• Locking System : The door is also provided with heavy duty hinges & latches with toggle type locking arrangement.
• Portability : Trolley mounting with casters for easy portability.

Air Circulation
The homogeneous condition of temperature inside the chamber maintaining by a forced blower with continuous duty rated TEFC motor for circulation. The conditioning space in the main chamber is baffled and heater and cooling coil is located in the conditioning space. The refrigeration unit is fitted under the chamber so as to ensure minimum space utilization.
Heating System
Low surface loading sealed tubular heaters conforming to IS-4159 provided to add heat in the chamber. The heaters are located in the conditioning space and there will not be any direct radiation of heat on the item under test.
Humidity System
Low-pressure moisture generator will be provided to generate moisture and add humidity in the chamber. The generator will be of minimum water level controller and mechanical float type refilling arrangement. Soft water will be used for the moisture generator.
Refrigeration System
Two-stage air cooled cascade refrigeration system will be provided working on freon 22 and 13 as refrigerants with evaporative cooling attachment for working in high summer ambient condition. The system is fitted with HP/LP cut off switch, overload protector, backup fuse protection etc. Low RH condition is maintained by smooth tube evaporation coil dehumidification arrangement.
Instrumentations
Dual loop microprocessor programmer with direct RH display is provided to carry out steady state as well as cyclic damp heat test. Solid state relay proportional control for heaters is fitted.
Control Panel
Control Panel will be provided at the lower side of the Chamber, which will house Microprocessor Based Programmer with direct RH display with Printing Facility, On/Off Switches, Fuses, Contactors, Indicating Lamps etc.
Wiring
All the channel type wiring will be as per IS code.
