The structure of JC-GDW410:
      The high and low temperature test box of JC-GDW410 motor is designed as an integral composite structure. The front of the box is the front door of the box, and the refrigerating unit is installed in the mechanical room at the back of the tank, the air cooling condenser, the forward wind and the rear air. The controller and the over temperature protection setting device and the lighting switch are arranged on the control panel.
      Outer wall material: 1.5mm cold rolled steel plate, sprayed with surface (pure white);
      Inner wall material: 1.2mm SUS304 stainless steel plate;
      Thermal insulation material: 125mm rigid polyurethane foam + superfine glass fiber;
      Bearing capacity: 100Kg/m2 (uniform load);
      Single open door hinge: hinge in the box on the left side (facing the box), the door inside by temperature resistant silicone rubber seal and anti condensation heating device, the door below the water pan, prevent the condensed water door wall low on the ground outside. On the door heat distribution, anti condensation hollow glass observation window (W400 * H500mm), the observation window is composed of multilayer insulating glass, the electric heating film can prevent the glass surface condensation and frost.
      JC-GDW410 high and low temperature test box at the back of the air circulation channel, from the upper and lower air supply, the passage of the installation of centrifugal fan, heater, refrigeration evaporator, drainage devices.
The unit box includes refrigeration unit, water supply and drainage device, fan and so on.
Total power supply, leakage circuit breaker, controller, power distribution board, heat radiation fan.
      Sample rack: 2 layers (SUS304), bearing 25Kg/ layer (uniformly distributed load).
      Lead hole: diameter 80mm Phi 1 (each with silicone rubber sealing plug 1).
      Location: lead hole center distance in the bottom of 450mm, horizontal uniform layout.
      Lights: 1 moisture-proof lamp 20W/DC24V, independent switch control.
      Casters: four casters can be installed to facilitate the movement of the box.
Heating system:
      Nickel chromium alloy electrothermal wire heater.
      The selection of high heat and corrosion resistant stainless steel plate and high quality nickel chromium alloy heating wire, a unique production process and the detection of advanced and refined, with fast heating, uniform cooling, reliable work, long service life and convenient installation.
Solid state relay (SSR) is used for contactless zero crossing triggering, driving heater work, no contact spark and noise, and long service life.
Anti integral saturation PID control heating power to achieve continuous adjustable power.
Refrigeration system:
      Structure: the refrigeration system is located in the lower part of the equipment unit, and the surrounding plate can be disassembled. The structure is compact, the layout is reasonable, and easy to maintain and maintain.
      How to work: mechanical compression refrigeration
      Evaporator: fin heat exchanger
