Test Holes
|
Can be used for connect external test power cord and signal (diameter 50 mm) |
Machine pulley |
Pulleys are movable and positioned with strong bolts (200Kg/wheel) |
Insulation Layer |
Rigid polyurethane foam (its advantages are: 1. High efficiency and energy saving, seamless after filling, strong bonding after curing. 2. Seismic and compressive resistance, no cracking, no decay, no falling off after solidification. 3. It has ultra-low temperature heat conductivity, weather resistance and heat preservation. 4. High efficiency insulation, sound insulation, waterproof and moisture-proof after curing. 5. waterproof performance is good, because the foam hole is closed, the sealing rate is 95%, and the rainwater will not permeate through the hole. |
Inner rack |
Movable adjustable grids and two stainless steel strip grids (5.0 cm per grille) |
Box door |
Double-channel heat insulation and tight gas to effectively isolate external temperature leakage |

Fault Abnormal Protection |
Cut off control power supply and fault reason indication and alarm output signal when abnormal fault occurs. |
Active Water Shortage Indicator |
Initiative prompt for lack of water on machine. |
Dynamic High and Low Temperature Protection |
Dynamic adjustment of high and low temperature protection value with setting conditions. |
Normal Temperature Protection |
After shutdown, the test area of the machine will be protected automatically by lowering to the normal temperature. |
Control Mode
|
1. The control system automatically adjusts the operation of the refrigerator according to the test conditions, so that the equipment is in the best energy-saving condition. 2. The refrigeration capacity of the evaporator is switched by the solenoid valve driven by the control system. 3. Compressor return air cooling circuit. |
