With step-less capacity modulation from 10% to 100%, the medium temperature range now offers a cooling capacity up to 26kW while the low temperature range with vapour injection technology offers up to 12.5kW cooling capacity.
The compressors are said to be ideal for multi-evaporator applications or any applications needing a broad range of capacity modulation such as multiple cold rooms in food service, small retail condensing units and compressor packs, as well as precision cooling or light industrial systems.
As well as efficiency gains and low noise operation, the low temperature model ZFD41K5E offers the capability of both liquid and vapour injection.
Models are approved and qualified for traditional refrigerants R404A, R407A/F and R134a as well as for low GWP alternatives such as R448A and R449A.
Emerson says that its compressors from the ZBD and ZFD range all have the same footprint, which makes their integration into different refrigeration systems easier for equipment manufacturers when used in a rack with existing fixed speed Summit K5 models.
Individual model performance data for the new ZBD76K5E, ZBD114K5E and ZFD41K5E is available for all refrigerants in Emerson’s Selection Software.
