Type EPL is a unit suitable for the control of integrated compressor packs and
associated condensing and defrost systems. The unit measures up to 3 suction
pressures and maintains each pressure within adjustable limits by running or
stopping compressors or by including or excluding steps of compression as
appropriate. Discharge pressure is also monitored and is maintained within
adjustable limits by increasing or decreasing steps of condensing as appropriate.
Type CP4C guards against compressor short-cycling, aims to maintain total running
hours for the compressors equal throughout the lifetime of the pack and
monitors fault conditions on each compressor.

Type CP4C may be used for externally compounded packs with a controlled satellite or standard dual temperature
packs.
Up to 6 defrosts per day can be achieved on each of the refrigeration systems associated with the pack by setting
a schedule of defrost start times, defrost durations and defrost patterns.

Compressors, condensers and defrosts are controlled and monitored by connecting JTL compressor pack interface
units to CP4C (see separate sheet IFx-x for details).
Suction and discharge pressures together with simple alarm messages can be indicated locally using JTL display units.
Type CP4C provides comprehensive alarm reporting, data-logging, remote data access and remote control of
defrosts at JTL refrigeration controllers when connected to a JTL Communications Unit.
