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 Im 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.

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. my question is that if we have no solinide valve or seprate system for purging as shown in video then what is method? we just have a valve for purging manually

Very good demonstration. Would appreciate if U cover Automotive HVAC system as well, Since most of the people would be needing this.

Why on the reciever in this video, is there only one pipe going by the reciever and not in and out like the video on single stage
