Our Inverter-driven models are the first in the industry to
use hard alkyl benzene
(
HAB
)
oil — a unique refrigerant
oil that degrades very slowly— for refrigeration. Em-
ploying our exclusive cleaning-free technologies such
as a specially developed high-efficiency oil separator
and optimum distribution of heat exchangers to prevent
oil stagnation, we have made it possible to reuse previ-
ously installed pipeworks.
PUHZ-RP71 Features
New HAB Refrigerant Oil
The refrigerant oil
(
ester oil
)
used for the 10.0–25.0kW
models will degrade when mixed with chemicals such
as chloride found in existing pipes. To prevent oil deg-
radation and make it possible to reuse existing pipes,
Mitsubishi Electric has developed an exclusive replace-
ment filter that uses activated charcoal to soak up
chlorides.
