EFC / EFCe Extension of production programme Electronic Frequency Control Systems
EFCe system - Electronic Frequency Control
Continuously variable speed control using frequency converter
technology
The EFC-System is optionally available for all Pluscom compressors HG(HA)12P,
22P, 34P.
NEW: EFCe-systems are optionally available for the compressors of the
series HG4 bis HG8.
With the EFC system Bock offers the most efficient means of adapting the
capacity of the compressor to current refrigeration plant requirements:
“Progressively adjustable speed control using frequency converter technology“.
Up to 25 % less power consumption!
EFC-systems are compactly mounted on the compressor, wired and connected
ready for use. It is activated by a pressure transducer mounted on the suction
side. The adjustment range can be set individually.
EFCe systems are also optimally adjusted to the compressor at the factory and
programmed with the necessary control settings. Due to their size, however, they
are not directly on the compressor but are instead intended to be set up
individually. The device is controlled via a pressure sensor arranged on the
intake side, or via an external control signal.
The trigger for the system (start/stop) is via a pump down pressostat. The
control range can be adjusted on an individual basis. The device is designed for
mounting on the wall or switch cabinet.
Thanks to the oil pump lubrication all Bock compressors are ideal for speed
control, in particular also for low frequencies.
