Description:
The whole system is a closed liquid circulation system with the expansion of container, expansion of the container and the liquid circulation is adiabatic, and do not participate in liquid circulation, only mechanical connection, regardless of the temperature is a high temperature or low temperature, the tank temperature is limited to 60℃.
The cycle is closed, there is no oil mist at high temperature and no water vapor at low temperature; Wide working temperature range of heat transfer oil; The entire circulation system without the use of the mechanical and electric valve.
The cycle is closed, there is no oil mist at high temperature and no water vapor at low temperature; Wide working temperature range of heat transfer oil; The entire circulation system without the use of the mechanical and electric valve.
FEATURES:
1. Wide working temperature range with cooling and heating function, temperature range: -55~250℃.
2. With 2pcs of LED display controller, can show the setting temperature & actual value, and alarm value for overtemperature.
3. Efficient fast, simple topping up liquid.
4. Ensure fast cooling at high temperature and can achieve 250℃~-55℃ temperature control continuously.
5. The cycle system is closed, there is no oil mist and water vapor happened, so as to assure the lab safety and heat transfer fluid lifetime.

The cooler is a very important part of the screw air compressor. The main function is to cool the lubricating oil of air compressor and the compressed air. If it's blocked, then the temperature will go up. A main cause of the air compressor failure at high temperature is the blockage of the cooler.
So what are the causes of the blockage of the cooler?
Dust is the most common cause of air compressor cooler blockage. It usually happens when there is no dust cleaning for air compressor cooler for a long time. On the other hand is the dusty environment around the air compressor.
If the place of air compressor station is harsh, and it is not well protected, blockage also occurs. For example, things as the broken thread of textile industry, sawdust of furniture factory, iron filings of steel works float in the air and stick to the cooler will lead to blockage.
Some users bought bad-quality air compressor lubricants out of their bargin-loving heart. Or if the air compressor runs in a high temperature for a long time, the inside of the cooler will form carbon and cause blockage. Reducing the amount of lubricating oil flowing through the radiator, results in poor heat dissipation.
There are three main reasons for the blockage of air compressor cooler, and we'd like to inform you to prevent the clogging of the cooler, ensure the normal operation of the cooler and improve the production efficiency. At the same time, it also requires users to clean the coolers daily, do the maintenance work in time, and find professional after-sales staff to deal with the problem.
