Evaporative condenserStainless steel brazed plate heat exchanger
Throttling deviceThermal expansion valve, capillary tube
Refrigerator control methodThe PLC (Programmable Logic Controller) of the control system automatically adjusts the operating conditions of the refrigerator according to the test conditions


Compressor return air cooling circuit

Energy pressure regulating valve

RefrigerantUsing environmentally friendly refrigerant R404A+R23 with an ozone depletion index of 0
Refrigeration system characteristicsThe pipelines of the whole system are tested for leak detection by venting and pressurizing 22kg.
The heating and cooling systems are completely independent.
Equipped with the company’s professional technical characteristics, it can prevent the damage of the high-temperature and high-pressure airflow co-current cooling machine.
All operating procedures of the refrigeration system are completely controlled by the microcomputer controller.
There is a drip pan at the bottom of the compressor, which can collect the condensation water produced by frost.
The compressor has its own PTC temperature sensor, when the compressor is over-temperature, it can realize over-temperature protection.
The compressor has its own oil pressure protector to realize compressor oil pressure protection.
The high and low pressure protection device monitors the pressure of the refrigerant during the working process of the equipment. Once the pressure of the refrigerant is higher than the limit pressure of the system or lower than the minimum pressure set by the system, an alarm will be issued immediately and the power supply will be cut off until the fault is eliminated .
The refrigeration system all uses imported brand accessories, which are reliable in quality and ensure the stability of the system.
Humidification & Dehumidification System
Replenishment methodThree-stage filter filtration, water pump lifts automatic water supply, circulating filtration and recovery
