Slmple Design with 649o Fswer PaÉs
Fewer parts than an equal capacity
reciprocating compressor means
significant reliability and efficiency benefits. The single orbiting scroll eliminates the need for pistons, connecting
rods, wrist pins and valves. Fewer
moving parts, less rotating mass and
less internal friction means greater
efficiency than reciprocating compressors, too. And the scrollcompressor has
been proven reliable in one of the most
rigorous test programs in the air conditioning industry.
Low torque Variation
The 3-D scroll compressor has a very
smooth compression cycle with torque
variations only 30% of a reciprocating
compressor. This means the scroll
compressor imposes very little stress on
the motor for greater relíability. Low
torque variation results in less noise and
vibration, too. Inherently smooth 3-D
scroll compressor operation allows the
use of industrial solid motor mounts
rather than less reliable spring mounts
required in many reciprocating compressors.
Exclusive Electronic Protestion
Advanced microelectronics protect the
compressor motor. The protection
system monitors compressor discharge
temperature and motor temperature.
Also protects against current overload.

reliability is further optimized with this
