POE
R448A & R449A
R404A
The POE oil RL46HB(215PZ) is an ISO VG 46
synthetic polyol ester (POE) lubricant formulated
specifically for use in refrigeration and air
conditioning compressors using HFC refrigerants.
This product provides effective wear protection
for steel and aluminum surfaces for increased
system life and improved efficiency and is
suitable for both initial fill and service fill. The
combination of low temperature characteristics
and unparalleled chemical and thermal stability
enable the use of RL46HB over a wide operating
temperature range.
R448A and R449A are two HFO-based
refrigerants with similar properties. Both have a
GWP below 1500 and comply with the EU F-gas
regulation.
They can be used as alternatives to R404A
refrigerants in MBP application.
R448A&R449A have zero ozone depletion
potential (ODP = 0). R448A&449A are especially
suitable for low evaporating temperature
applications but they can also be applied to
medium evaporating temperature applications.
R448A &449A are mixtures and have big
temperature glide, and therefore must be
charged in their gas phase.
R404A is an HFC refrigerant. R404A has zero
ozone depletion potential (ODP = 0). R404A is
also suitable for low evaporating temperature
applications but it can also be applied to medium
evaporating temperature applications. R404A is a
mixture and has a very small temperature glide, and therefore must be
charged in its liquid phase, but for most other
aspects this small glide can be neglected.
Because of the small glide, R404A is often called a
near-azeotropic mixture.
