Re POE oil & R507.
I was looking for more than that article actually. As far as rotary Valve seats I don't know. But in Herms & Simi herms The valve seats arent harded, Sort of like when cars went from Leaded gas to unleaded gas. running unleaded in a engine with out hardened seats they run normal for a while but wears the seats and valve face. Hence the oil being carried by the refrigerant. replaces the hardened seat and provides a cushion so to speak( like the lead in leaded fuel did in a automobile engine). Mixing the charge may help to a degree. Like lead additives did for auto engins .
This is just what we have seen with refrigeration compressors in walk in freezers. and chiller systems. Like i said as far as rotaries I dont know. But if seal deterioration occurs it also contaminates the oil in a sealed system . Hindering its ability to lubricate the bearings and seals , valves.
Also POE oils are better suited for lower temps before the velocity is compromised . Just sucks that they absorb moisture at a lot faster rate. Therefore a leak on the Low side. esspecialy in a phase unit that works in a vacuum sometimes (or all the time) will accumulate moisture faster. and remain in the oil instead of collecting in the drier filter . To a point where if can displace the oil ( in a bad leak Faster than Acid formation can occur.
Ok I am ranting now Sorry.
Hope this helps or makes sense

Hey Scott, the guys over at NBOC have said some great things about you and your phase units. I would like to talk to you about getting in line for the next unit after Ricks and Maadaawg's. It would be kewl to get you over there at least to familiarize your product to the rest of our HWBot team and forum. Please contact me at your earliest convienance

Hello sdumper - This is rickss69 (Rick). MaadDaawg (Jim) phoned me and said you were thru with his phase unit and that I should get in touch. Are you in a spot where you could build me one like his? Been using chilled water and have gone as far as I can go with it. Benching is all I intend to use this for. I am ahead of Jim in points for the moment, but he is gonna blister me shortly lol. Let me know what info you need.
