Heating lnsulation Suitable for Brazed Plate Heat Exchanger

Brazed plate heat exchanger in brazing connection must pay attention to maintain the heat exchanger welding surface clean, no dirt, no grease. Before heating, dry nitrogen must be used to replace the air in the pipe and heat exchanger, and a wet cloth with water must be wrapped around the root of the short tube of the heat exchanger to protect the heat exchanger. In the brazing connection, it is necessary to use a special silver content of more than 45% of the electrode, the flame must be weak flame, so that the solder can be evenly fused into the stainless steel, while the heat exchanger connector only needs to be heated to the low temperature required for brazing, and should be cooled quickly after brazing. Note that the entire brazing and cooling process must be run under nitrogen protection, and the parts cannot be immersed in water for cooling. A wet cloth can be used to wipe the parts to accelerate cooling.

Heating insulation for a brazed plate heat exchanger is important to minimize heat loss and improve the overall efficiency of the system. 

When the temperature of any heat exchanger is below zero degree Celsius, the water in the heat exchanger has the possibility of freezing. In order to prevent the heat exchanger from freezing due to low temperature, the air conditioning unit must be installed with a drainage valve. When using, pay attention to keep the water circulating and heating, and the water should be drained when not in use.
