What is the reason for non condensable gas in the condenser of ultra-low temperature cooling water c
When the ultra-low temperature cooling water chiller is running, it is necessary to pay attention to the gas state generated by the condenser under a certain temperature and pressure. The existence of these gases affects the operation of the ultra-low temperature cooling water chiller. What is the reason? 1. The refrigeration system is not fully drained before charging refrigerant Before the ultra-low temperature cooling water chiller is charged with the refrigerator, the compressor cylinder,...

How to use the reactor thermostat？
The reactor thermostat is generally heated by a resistance wire, cooled by a compressor, and is supplemented with a PID controller to maintain a relatively standard temperature, so as to achieve the purpose of the experiment. The shell is made of metal plate, and the control box is directly installed on the water tank. There are two water inlets and outlets for the condensate pipe next to it, and the water pump is used as the circulating power in the water tank, which solves the problem of un...
