How to choose the appropriate refrigeration equipment/freezer/industrial water unit?

The commonly used auxiliary accessories for industrial cold water electricity include the following, The first one is the water flow switch, which is used for flow control or cutoff protection in the pipeline. When the fluid flow reaches the set value, the switch will automatically cut off. The second one is a pressure controller, which is used for pressure control and protection. There is a controller for low and high pressure, which is used to control the pressure. When the system pressure reaches the set value, the switch will automatically cut off. The third one is the pressure difference controller, which is used to control the pressure difference. When the pressure difference reaches the set value, the switch will automatically cut off. The fourth one is a temperature controller, used for control and protection of equipment. When the temperature reaches the appropriate value, the switch automatically cuts off the circuit. The fifth one is the solenoid valve. When the compressor is stopped, the circuit of the system is cut off to avoid the generation of a hydraulic machine in the next use. It is generally used in larger intelligent systems.The commonly used auxiliary accessories for industrial cold water electricity include the following, The first one is the water flow switch, which is used for flow control or cutoff protection in the pipeline.
