Application range

2.4.1 Qualified refrigerants and oils

IMPORTANT
It is essential that the glide of refrigerant blends (primarily R407A and R407F)
be carefully considered when adjusting pressure and superheat controls.
Oil recharge values can be taken from Copeland Scroll compressors brochures or Copeland™
brand products Select software available at www.climate.emerson.com/en-gb.

2.4.2 Comparison between ZB*KCE and ZB*K5E compressors

ZB*KC and ZB*K5 models are based on the same compressor platform, but there are slight
differences. Table 2 hereunder explains the differences and similarities between ZB*KCE and
ZB*K5E models:

2.4.3 Application limits

CAUTION
Inadequate lubrication! Compressor breakdown! The superheat at the
compressor suction inlet must always be sufficient to ensure that no refrigerant
droplets enter the compressor. For a typical evaporator-expansion valve
configuration a minimum stable superheat of at least 5K is required.
The application envelopes for the refrigeration Scroll compressors with various refrigerants can
be found in Copeland brand products Select software available at
