Glycol Cooling Heating Control System

Glycol Cooling Heating Control System

  • Glycol Cooling Heating Control System
Glycol Cooling Heating Control System
  • Product Description
  • Knowledge Center
Application:

The tested object is attached to a test platform adapter.
The inside of the part was cooled and heated by an aqueous solution of ethylene glycol.

The test component needs to undergo a specific temperature profile and record changes in temperature. Temperature variations typically range from -40 to 100 degrees.
When performing a tolerance test, it usually takes an infinite loop.

Antifreeze temperature from -40 degrees to 100 degrees
Very steep temperature gradient change
Export temperature limit
Visualization, data storage, and reporting analysis
Temperature control equipment can be flexibly connected to other test platforms

Equipped with a powerful circulation pump while ensuring the delivery of highly viscous liquids.

Control the flow output with a proportional control valve to achieve high-precision control of the total range 5% to 100% adjustment

Maintenance of Glycol Cooling Heating Control System
Apart from the attention needed during the daily use, the regular check and maintenance of Glycol Cooling Heating Control System are also very important. In order to help all of you learn to use Glycol cooling heating more efficiently,   Guanya Refrigeration sort out related maintenance, so that you can use it in time.

Screw Compressor

Screw compressor is a very important part of ethylene glycol refrigerator, and the compressor is directly related to the stability of the unit. If the compressor has something wrong, In view of the high precision of the assembly precision of the screw compressor, the factory is usually required to carry out the maintenance, so it needs to be paid more attention in the ordinary use process in using.

Condensers and Evaporators

Is there is something wrong with the Glycol cooling heating control system, in view of the high precision of the assembly precision of the screw compressor, the factory is usually required to carry out the maintenance, so the compressor needs to be paid more attention in the ordinary use process.

Washing of condensers and evaporators

The cooling water of the water-cooled condenser of glycol refrigeration unit is open loop circuit. The circulating water is usually used by the cooling tower. When calcium the content of salt and magnesium salt in water is large, it is easy to decompose the fouling between the pipe and rock, and the heat transfers. Once the scale of the condenser of glycol cooling system is too thick, the cross section of the cooling water will decrease, the water volume will decrease and the condensing pressure will increase. Therefore, when the water quality of the cooling water is poor, the cooling water pipe should be washed at least once a year to remove scale and other contaminants. Of course, not only glycol cooling system but other other related cooling equipment used for a period of time, their maintenance knowledge is needed to learn in everyday use.
