Remove the Sight glass recharge to 4 PSI Suction Test at 180 watts for ten min, monitor temp every 1 min write it down, remove charge to 2 psi suction repeat, when charging let it run for 10 min...

Never use a sight glass in a capillary tube system, you do not want a full liquid line, capillary tube systems utilize the cold suction line to provide cooling to condense the final portions of the...

Two things,, Reducing the refrigerant inthe system will lower the capacity and the temperature, lengenthinging the capillary tube and keeping the same volume of charge will appear to do the same. You...

basically you can't, you need to inject enough liquid back into the suction side of the scroll to cool it, currently a special TXV is used it senses the temperature on the top of the compressor this...

Compliant scrolls are not good candidates for high vacuum systems. if oyu want a real high vacuume compressro we use to use a schanaki belt drive 120 cuin displacment, these had a five to 25 hp motor...

OK n o worries.. Think its bad there I am from Western Maine Mountians,, you happen to know of the bases north west of you .. rangley tomahawk target range,, my old fishng grounds.. enough off topic...

1, Large size, noise, starting ( use a potential relay and a 200uF start cap you will need an adjustable universal potential relay because there are none manafacturered for that compressor...

Put the larger compressor in the second stage and add a large air cooled condenser before the HX it will increase the effeciency

Critical data.... 5512 EXA
the first letters are family and config
second five, decimal places in BTU rating
12 is the first two numbers in the btu rating
so 12,000 BTU or one ton...

Use a standard reversing valve,,, ranco makes them for about $100 USD you can get coils for the pilot valve in ac and dc voltages from 24 to 460V usually used in heatpumps for swiching the evaporator...

Cap tube, and if you want a challenge add a phase seperator and a second stage gas.. how about using off the shelf gasses like R154A From fry's (cleaning fluid) and BBQ gas, See what this will do, of...

First stage use R290 and R507 Use the R290 to subcool the 507 and remove the oil from the evaporator this will add capacity to the system also subcooling the liquid line wiht the returning...

1.375 was the original,, the new hold down uses none. you can make one by flattening a # 10 copper wire drawn into a circle.

I have R503, R23, R1150, Iceon89, R116, R14, and about 15 others Now I can mix up some R508 for you but I can only get the blend within a few percent of correct. Costs per pound is astronomical the...

anyone tried a craftsman vacume cleaner?? simple air pump...

I have a 2.2 CFM 3PH 208V Carlyle (About 2 hp) smallest one I have ever seen.

Tring to make time to get back in here and fix that ;)

LOng time .. At it still I see:)

R1150 has -109C boiling point at ATM so with a -.1 BAR you have a delta of 10C not bad, Delta is everything, so for a lower temp you need a lower pressure and a greater flow rate, larger displacment...

How about this, I and my Helper will build a single stage. He has never done an entire cooler from the ground up and has only a rudimentary understanding of refrigeration systems in general. I will...

THanks. Well just thought you might get some inspiration having one of these olittle evaps and hold down kits setting on your shelf if nothing more than an interesting conversion piece... Ha ha just...

R152A appears to be ventable. (It is used to clean electronic components :) ) and one advantage is that it is misicible with mineral oil. it does wirk as R12 replacment but I am not sure about...

sorry is this a 220V 50 HZ compressor?
