FAQ
Q. What applications does the vacuum pump cover?
Ans. In refrigeration, a vacuum pump is used to remove air, moisture and other gases from the refrigeration system before it is charged with refrigerant. This process, often referred to as “evacuation”, is crucial to ensure the proper functioning of the refrigeration system.
Q. Why is the vacuum pump an important tool for evacuating refrigeration systems and heat pumps?
Ans. The refrigerant works reliably in only a clean system and makes full use of its physical advantages. The vacuum pump ensures that the system is freed from disruptive influences such as foreign gases and moisture before filling.
Q. What additional functions does the vacuum pump offer?
Ans. Additional functions are the integrated vacuum gauge for displaying the vacuum achieved, easy checking of the oil level on the pump through a sight glass and the gas ballast valve to reduce the disruptive effects of moisture on the oil and the resulting corrosive effect on the components of the vacuum pump. The connection block facilitates the connection of different hose sizes to the pump.
Q. How can the vacuum pump contribute to improving the efficiency and reliability of refrigeration systems?
Ans. By evacuating refrigeration systems and heat pumps quickly and thoroughly, the vacuum pump helps to remove moisture and contaminants, which improves the efficiency and reliability of the systems. This can lead to a longer service life of the systems and less downtime.
