AACHEN (GERMANY), October 15, 2014 – Emerson Climate Technologies, a business of Emerson (NYSE: EMR) presents its range of Copeland Scroll ZO compressors with new re-rated stand still pressures 30 bar suction and 52 bar discharge for R744 (CO2) subcritical applications at Chillventa trade fair in Nuremberg.
With the recent release of the Digital Scroll ZBD compressor range for R134a, Emerson is now able to offer advanced scroll compressors for cascade systems in combination with Copeland Scroll ZO compressors for CO2 subcritical applications:
- For medium-temperature applications, Emerson provides scroll compressors for supermarket packs up to 90 kW cooling. The Copeland Scroll ZB and ZBD compressor range offers 19 models with cooling capacities from 2 kW to 15 kW with R134a including Digital Scroll models, which are able to modulate capacity from 10 to 100%.
- For low-temperature applications, Emerson provides scroll solutions for supermarket packs with cooling capacities of up to 60 kW. The Copeland Scroll ZO and ZOD compressor range offers eight models with cooling capacities from 4 kW to 23 kW for R744, also featuring Digital modulation. The Scroll range is designed to provide the best performance for the low temperature side of CO2 booster and R134a/ R744 cascade systems used in retail refrigeration.
The use of scroll and Digital modulation technologies in these cascade systems supports our customers and end users to offset the additional capital costs. These cots are related to R134a and R744 compared to standard HFCs such as R404A.
Cascade systems using R134a and R744 provide opportunities to reduce CO2-equivalent greenhouse gas emissions and to improve the energy efficiency of the equipment. They also represent a strong alternative to systems using common refrigerants, especially in consideration of the upcoming F-Gas regulation (R404A GWP=3.922; R134a GWP=1.430; R744 GWP=1).
