Information for Systems Using POE Oil Lubricant

POE Oil, or Poly Ester Oil, is a synthetic oil that can be used to lubricate refrigeration compressors. 

 

When using Corzan CPVC piping in Hydronic Heating and Cooling applications, it is important to note that Polyol Ester (POE) lubricants are incompatible with CPVC and will likely cause cracking of the fittings and/or pipe if they are released into the recirculating fluid or condensate drain.(See HVAC Design Guidance for steps to take should such a release occur.)While refrigerant and/or compressor lubricant should not normally enter the recirculating fluid in a properly operating system, they may be released into the recirculating fluid and/or condensate drain in the event of a rupture of the heat exchanger.

 

If a specified chiller within an HVAC system will be using POE oil, it is imperative that the system designer verifies with the Chiller Manufacturer that compressor oil will not enter the recirculating fluid or condensate drain. Lubrizol is not aware of any failures of HVAC piping systems that have been caused by other types of compressor lubricants including mineral oils, polyvinyl ethers (PVE), polyalkylene glycols (PAG) or polyalpha-olefins (PAO).
