All return gas is routed over the motor.
This managed motor cooling allows the Duration compressor to run 35 degrees
cooler than other hermetics leading to longer life and lower operating cost.
Withstanding the test of time
What’s so special
about the
Duration compressor?
Well, first of
all it’s
designed for
the extreme
stress conditions
of heat pump applications.
A compressor used
in a heat pump must be
able to
overcome higher
operating temperature,
Liquid refrigerant flooding,
adverse electrical stress,
and the stress
of longer
operating hours.
The Duration
compressor’s reputation
was built
on its
ability to
handle these tough
conditions. Of
course, these
features also
benefit the
air-conditioning application
as well.

All critical
system, components go through
three stage of testing:
as a
component, as a
compressor, and
as the
final unit.
For quality
assurance, the
Duration compressor is
tested and retested in our
System Extremely
Environmental Test Center (SEET),
which tortures it
with 16
weeks of
intensified wear
and tear,
duplicating five
years of
actual field
stress.
In fact, compressor
reliability is
directly related
to its
ability to
handle stress.
Stresses encountered by hermetic compressors
can be
typically categorized
as thermal,
mechanical, electrical
and chemical.
Many of
these stresses
are interrelated,
and any
of them
can impact
unfavorably on the life of
a compressor. The Duration compressor is uniquely designed to
withstand these stresses. Nobody builds a better compressor , these things
are built to last. Excellent design and quality construction are hallmarks
of these machines.
