Refrigerating compressors
Copeland Scroll™ compressors
Copeland Scroll compressors are available in 3 different ranges:
For high temperature applications
, ZR type compressors, suitable for evaporating temperatures of +12.5°C down to -20°C and cover models from 1.5 to 30 hp
For medium temperature applications
ZB type compressors, suitable for evaporating temperatures of +7°C down to -30°C and cover models from 1.5 to 30 hp.
For high temperature applications
ZF type compressors, suitable for evaporating temperatures of +7°C down to -40°C and cover models from 3 to 15 hp
Today CopelandScroll™ experience
Today Copeland’s experience of millions of scroll compressors installed world wide makes the advantages of this leading technology widely recognized in refrigeration
- designed to meet the specific needs in refrigeration
- offer
an improved design to reach the level of seasonal efficiencies
that no other technology can provide for medium and low temperature applications.
- this equates to
the lowest energy costs
- the broad application envelope of scroll allows quick pull-down operation and
ensures that temperature set-points are reached faster
- high efficiencies all year round: Scroll
does not suffer from gas reexpansion
typically found in reciprocating technology
- Copeland’s patented Compliant Scroll™ design operates under continuous scroll flank contact, maintained by centrifugal force; this
minimizes gas leakage and maximizes efficiency
- the dynamic discharge valve installed in the compressors allows the
discharge gas to reach the desired pressure
, considerably improving the efficiency of the compressor at high compression ratios by avoiding gas re-compression
the injection of vapour at intermediate pressure directly in the compression stage
allows demonstrate efficiencies comparable to reciprocating compressors for low temperature applications
Copeland Scroll Digital™
is an innovative technology that allows to precisely match capacity to the desired load of the equipment at minimum power consumption
the weight is reduced by up to 50%
compared to standard semi-hermetic technologies
- all scroll compressors undergo severe
qualification tests during their design
phase
to ensure maximum reliability during their life cycle. Conditions under which they are tested are well beyond the most demanding refrigeration applications found in the field
- all Copeland Scroll™ compressors use
Teflon coated bearings
that significantly improves the reliability of the compressor; even in demanding applications Teflon acts as a lubricant if the oil film disappears in case of poor oil return to the compressor
- scroll compressors
throw less oil in the system
than other technologies
