Compressors
The majority of the Heatcraft Parallel systems incorporate the
Copeland compressor. Other brand compressors are available
upon customer request. The compressors are solid mounted
to a base frame or mounted on the refrigerant receiver. All
reciprocating compressors incorporate oil oats. Crankcase
heaters will be installed and wired. Cylinder head cooling fans
will be installed on all low temperature reciprocating systems
or as directed by the specic compressor manufacturer. A high
pressure cutout and oil failure control are installed and wired
for each compressor.
Many compressors are available with unloading for capacity
control. The unloading of a compressor adds many capacity
steps to those normally available to an electronic controller.
Usually, the more steps available the better the load can be
matched.
