Copeland Scroll ZFD*/ ZBD* Digital for MT & LT

Copeland ZBD and ZFD scroll digital compressors provide stepless continuous capacity modulation in medium and low temperature refrigeration applications. Digital scroll technology - based on the unique Copeland compliant scroll design - is a simple modulation solution that can easily and quickly be implemented into any existing system design as no other components are required. Digital scroll technology provides continuous, stepless modulation from 10% to 100% with no operating envelope restriction. As result, system pressures and temperatures are tightly controlled. These compressors provide optimum performance for refrigeration units, refrigeration packs, process and agricultural units.
