ZX Series Scroll Condensing Unit by Rishabh Enterprises

Reliable equipment and lower energy costs are at the top of the list of needs for the food service and industrial operators. By combining the proven reliability and efficiency of Copeland Scroll™ compressors with the existing benefits of the Copeland™ condensing units these needs can be met.

Scroll condensing units are available for medium and low temperature foodservice refrigeration applications and optimized to work with HFC refrigerant R-404A, a reliable alternative to HCFC.

R-22. For the industrial segment the units are available in high and medium temperature and optimized to work with HFC refrigerants R-404A and/or R-134a, both reliable alternatives to HCFC R-22.

FEATURES

The fixed capacity ZXL low temperature units come with Emerson Climate Technologies’ highly successful “E2 Controller”. The E2 controller provides real-time monitoring of compressor operating conditions and initiates actions to keep the compressor within the safe zone. When fault conditions are detected, the controller initiates temporary shutdowns and sends specific warning signals to facilitate service. In the event of continued errors, the controller will shut down the unit thereby preventing costly equipment failure and send alarm signals. ZX low temperature units applies vapour injection technology. This allows an economizer cycle on scroll compressors. Vapour injection significantly improves the low temperature operational efficiency and extends the low temperature envelope

ZXD Series

The ZXD range of Digital modulated medium temperature units benefit from patented Digital scroll technology. This allows a simple and very reliable variable capacity system.

The Digital modulated variable capacity ZXD medium temperature unit comes with Emerson Climate Technologies proven “EC2-552” controller. The EC2 controller provides real time load estimation and controls the delivered capacity by changing the Digital modulation rate. The controller also provides the basic protection including the high discharge temperature trip. The controller also displays the suction pressure, saturated evaporating temperature based on the suction pressure, modulation rate and discharge line temperature.
