When soldering flux is used to remove oxides from the metal surface, this property makes the flux potentially very aggressive. How water is heated in a heat exchanger depends on the design features of the equipment. Repeat for the other side. For evaporators, it is practical to measure the water temperature inside the heat exchanger. The chamber in which the pipes are held are made out of plastic or coated with thermal insulation to keep heat from escaping. Not beneficial for large fluid temperatures.
This will give a faster response when there is a small load. This means that refrigerant will enter the evaporator in connection F1 and gas will leave the evaporator from connection F3.

Also, it is characterized by an increased flow rate of the coolant. The expansion device should be positioned not less than 150-200 mm from the connection (S3). In addition, tighten and configure each plate pack to ensure maximum performance and reliability in the exchanger.
Excessive cycling amplitude of pressure and temperature can lead to leakage after some time as a result of fatigue phenomena. The material's structure can be altered if the temperature is too high, resulting in internal or external leakage at the connection. The tightening torque for the 5/16″ bolts is 90-105 in-lb; for the 3/8″, it is 195-221 in-lb.
