Fridge compressor questions!

Unread postAuthor: pipeboyswe » Tue Jun 21, 2011 8:43 am

Hi guys! :D
Q1: What compressor would be best for high pressure (200-500psi)
They are all Danfoss, TL2, TL2.5 or the TL4?

Q2: And if i would connect them in 2stage witch two would feed to the third for the highest pressure?

Q3: When i plugged in my TL2 the first time ALOT of oil sprayed out, and when i connected it with a gauge it pumped very slow and only to 250psi and everytime i use it it pumps even less... :( , so if i would put in new oil (same oil that is used in regular compressors) would it pump faster and higher pressure or it is broken or something?

I culd only find TL2.5, 3 and 4
each model has different displacement and motor.... theoretically speaking all of them should be able to reach more less the same pressure (as higher displacement versions have stronger motors & because they all use the same refrigerant) so I'd choose model TL4 as it will pump whatever you want faster

supposedly yes, but I never tested that

what do you mean by
ALOT of oil sprayed out
add some engine oil and see if it helps... if oil is essential for sealing of the pison or something then even just a little bit of it added through the inlet while the compressor is working should fix that... if not that's not the problem and it is broken
