My question is how do these gasses get into the system? and what rate, we talking purging a tiny tiny amount out every month or we talking this is a 24h operation?

Hi Simon, it's going to result from leaks, service work and chemical reactions so each system is different. This unit runs and monitors the system 24/7 and utilizing control algorithms developed by Danfoss, the controller determines when the collected air is pure enough to open the discharge solenoid valve.

In industrial systems, suction pressure might be set to around -0,2bar to reach a colder temperature in the evaperator, hence increasing the efficiency. This has the unfortunate side-effect of sucking in air in the cold side of the system. Although a system is tested to be completely sealed with positive pressures, that might not be the case with negative pressure. An air purger is often the solution

Most purgers use high pressure liquid ammonia and an expansion valve to condense the ammonia in the foul gas off the top of the HPR if I’m not mistaken. I usually deal with Hansen purgers and have even seen one on a Frick 150 ton screw package running on R22 serving a spiral freezer. Great video though! Cool seeing what other equipment is out there! Do you know what Danfoss does to avoid corrosion of the piping in the purger refrigeration circuit? Is the evaporator coil stainless or steel?

What's the benefit of Danfoss using a separate refrigerant system in their purger? Hansen and Parker models use HPL ammonia and house suction to cool the discharge gas & non-condensables.
