Low temperature test chambers structure

• Material:
  Outside material is High quality coldroll steel sheet with electrostatic powder coating treatment. Inner chamber adopts imported SUS304 stainless steel plate.
• Component Part:
  This equipment integrates its main box, refrigerating unit and electric control parts. Unit is at the bottom of main box, control cabinet is on the right, blower motor is at the top and low temperature pipe section is installed at the top of its back.The main box includes working room and airconditioning chamber, which contains fan blade, heater, evaporator and sensor from top to the bottom.
• Thermal Insulation Material:
  Hard high and low temperature resistance polyurethane foam and superfine glass wool with good thermal insulation performance to ensure the test chamber surface with no frosting and condensation.
• Inspection Window:
  Rectangle multilayer electric heating hollow glass window to prevent condensation.
• Cable Port:
  Two through-hole are made of low heat conduction material with a diameter of 80mm, two insulation plugs are matched on the two sides.
• Floodlight:
  Low pressure light.
• Gate and Seal:
  Door frame adopts high and low temperature resistance silicone rubber seal strip, and frame is designed with safe voltage electric heating tape to prevent condensation.
