  • Knowledge Center

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.


FEATURES:

1. Wide working temperature range with cooling and heating function, temperature range: -20~200℃.
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 acheive 200℃ ~ -20℃ temperature control continuously.
5. The cycle system is closed, there is no oil mist and water vapor happend, so as to assure the lab safety and heat transfer fluid lifetime.
6. Use copeland brand compressor, circulation pump, stable performance and reliable quality.
7. Self-diagnosis function; freezer overload protection; high-pressure switch, overload relay, thermal protection device, liquid low level protection, high temperature protection and temperature fault protection.

The related accessories of Heating And Cooling Systems

The selection of heating and cooling system is quite important, not only price and temperature control, but also quality should be taken into consideration. Besides, you should also pay attention to the accessories of heating and cooling system.

Filter:
The installation of the filter in the pipeline is necessary, for it can effectively prevent the pipeline blockage, the deterioration of heat conduction media and other problems. The negligence about it may cause property loss and safety accidents. What's more, the filter needs to be cleaned or replaced regularly.

Pressure gauge:
The pressure gauge is the key in the cooling and heating equipment. It closely records the pressure of the pipeline and discovers the pressure state of the pipeline in time. It can find the high and low pressure problems in the pipeline in real time and modify it.

Pipe bypass:
The outlet and inlet of heating and cooling system should be connected by three-way and manual valve, then make a proper diversion according to piping pressure.

Manual valve:
Put manual valves on the connection of heating and cooling system and both ends of the components installation, thus the heating and cooling system can be easily disassembled in maintenance, so that reducing the loss of heat conduction medium, and the related valves can be closed in time when in trouble.

The parts of the heating and cooling system are not fully included above. In order to ensure the stable operation of the equipment, we should take full consideration of the temperature range, the pressure range, the use of the environment and other specific knowledge of the components.
