What is POE oil used for?
Polyolester (POE) – the primarily synthetic oil for refrigeration systems using HFC refrigerants. It is also suitable for refrigeration systems using CFC, HCFC refrigerants and being evaluated in CO2 systems.
Is ester oil and POE oil the same?
POE/ESTER OIL The transitional solution was polyol ester oil (“ester” oil or POE). Ester oil is often called “retrofit oil” because it mixes with both R-12 and R-134a. Like PAG oil, Ester oil is a synthetic lubricant.
Are there different types of POE oil?
However, not all POE oils are the same. There are a variety of POE oil types and grades and it is important to know which POE oil is in the system being serviced. Mixing incompatible POE oils may create problems and lead to compressor failure.
Is R22 compatible with POE oil?
Doing so could save you a considerable amount should your system develop a leak in the years ahead. All new compressors use POE oil and are compatible with R407c and most other R22 replacement refrigerants.
Is POE oil toxic?
: Under normal conditions of storage and use, hazardous reactions will not occur. No known significant effects or critical hazards. No known significant effects or critical hazards. Repeated or prolonged exposure to spray or mist may produce respiratory tract irritation.
Can you mix mineral and POE oil?
Can I mix Polyol Ester (POE) and Mineral Oil (MO) together? When using CFC or HCHC refrigerants, POE and MO can be mixed. The exception is R12 that only uses MO or Alkyl Benzene Mineral Oil (ABMO) blend.
What is the biggest concern with POE oil?
One major concern with POE oils is that they are hygroscopic. If they remain in contact with air, they have the ability to absorb its moisture. For a technician, this means that when a repair requires opening a system, it should only be left exposed to the atmosphere for as long as necessary to complete the repair.
Is Poe oil toxic?
Can I replace R22 with r410a?
The extensive system changes are required because R-22 and R-410A refrigerants are not interchangeable and cannot be mixed in the same HVAC system. These products have very different heat-transfer properties and use chemically incompatible lubricating oils.
Is Poe oil flammable?
Flammable limits : Not available.
At what temperature does POE oil breakdown?
Mineral oil will start to decompose at approximately 350ºF (400ºF for POE oil). As temperatures increase above this threshold, the oil starts to polymerize.
