Nitrogen Welding Refrigeration Tech Temperature And Humidity Chamber For PBC Testing
Nitrogen welding Refrigeration Technology Temperature Humidity Chamber for PBC testing
1. High Performance Temperature Humidity Chamber Application
Applicable to environmental adaptability and reliability test in such industrial units as electronics, electrical appliance, battery, plastics, food, paper product, vehicle, metal, chemistry, building material, research institution, inspection and quarantine bureau, university etc..
Insulation box:
wall material: high-quality carbon steel with static color spray
inner wall material: SUS304 # matte stainless steel plate
Insulation materials: rigid polyurethane foam insulation layer + glass fiber.
Door:
Heating wire was installed at the door frames to prevent condensation at low temperatures.
Humidifier:
Basin heated humidification
Stainless steel sheathed heater
Heater control: non-contact period, such as pulse width modulation, SSR (solid state relay)
Water level control devices, anti-dry unit heater
Refrigeration Technology
Nitrogen welding, two-stage rotary vane vacuum pump, ensure that the internal cooling system clean and reliable.
water tray located at the bottom of the compressor to ensure condensate water drain through pipe freely at the rear of the chamber.
