Hey what are you guys using to move large quantitys of refrigerant?? Like 1500 lbs in hours not days..
Big hoses. I use a 3/8" hose on 100 pounders. I'd be looking for a 1/2" hose for a 1500 pounder. The 3/8" hose will typically empty a 100 pounder in under 10 minutes.
We call a refrigerant handling company. They take care of it all and we don't have to invest in the equipment.

on a what? chiller? field built up system? i push 1000's of pounds around. i can drain a 1000 pounder in about 50 minutes or so.
boBert, it was you who started the thread and I surfed & searched to find cool refrigerant transfer machines. Posted links and all that, you never even responded if you bought one or not. I could have been looking at porn all that time but NOOOOOO I wanted to help someone!
i use 1/2'' hoses. i have shanghaied a blue oval pump out off a dead XL and put it on a cart. we just ordered some hi pressure liquid pumps from nrp, should have them tuesday. http://www.nrproducts.com/products/pdf/refpumps.pdf http://www.reftec.com/shop/item.aspx?itemid=13 just ordered a hi pressure transfer unit, with 3/4 hoses. it's about 3 weeks away. http://www.reftec.com/shop/category.aspx?catid=1
there you go.............. i'm getting ready to move around an ocean of r22............ if the stress doesn't kill me, or i quit.
you can safely pump out a chiller in 2 days, 1st day get the liqwid, and pull vapor down to 34 degrees. let it break back over nite, and depending how far she comes up, get the rest of the vapor in the morning. i do it all the time, and i do not have the luxury of running a chw pump.
Everyone knows that I've been in this business since the ice age. Back when all the recovery regulations first started to come into existence I made a recovery machine out of an old Brunner belt driven refrigeration condensing unit. When the EPA phased in the requirement to have "approved" recovery machines they left a little lope hole in the regulation that grandfathered existing equipment used for recovery. At the time I registered my contraption. It was approved with a rubber stamp and we have been using it ever since. We transfer refrigerant from the field rec. cylinders to the 125 lbers.
I did about the same thing except I used a York automotive compressor, worked great, but a usual I mad the damn thing way too heavy, but it worked good in the shop, and they approved mine too One time my buddy and I were drinking beer before they even started the recovery thing and I told him we ought to start making the machines, they are gonna make us do it, but we just drank beer and that's as far as it got I remember the first ones were just a 1/3 condensor and people would pay like $1800 for them figured somebody that was in the business could figure out the machines aren't that complicated
