UNBELIEVABLE ENERGY EFFICIENCY!
A GAUTENG METERING COMPANY WAS RECENTLY CONVINCED THAT THEY HAD FOUND A FAULT WHEN A LARGE RETAIL STORE “INCREASED IN SIZE BY 50% BUT REDUCED ENERGY CONSUMPTION BY 30%”
Bitzer compressors were selected for their energy efficiency and reliability to be at the heart of the new co2 refrigeration system in the Woolworths Crowthorne store.
When Woolworths was redesigning and expanding their Crowthorne store , Commercial Refrigeration Services (CRS) looked to BITZER as a natural choice in compressor to create exceptional energy efficiencies and drastically cut back on power usage.
At the heart of the system are 7 BITZER CO2 compressors that are incorporated into a new parallel compression design.
The system was designed and installed by Commercial Refrigeration Services in Johannesburg, and Wynand Groenewald explains further: “The system uses seven Bitzer C02 compressors. Five of these are medium temperature compressors together with two low temperature compressors. Of the five medium temperature compressors we have designed a new format system that use 2 of these to provide parallel compression, which achieves much better energy efficiencies”
The new system has proved so effective the Groenewald reports that the metering company recently paid a surprise visit to the store to check for a fault. “They were convinced that there was a fault because they saw that the store had increased in size by 50%, but that they had a 30% reduction in energy usage!”
This would be music to any retailers ears and CRS is monitoring the store for power consumption reduction over a longer period of time.
“We feel that this new type of parallel compression system is the way forward for C02 in Africa”, said Groenewald.
BITZER is the world’s largest independent manufacturer of refrigeration compressors and they work closely with OEM’s, consultants and contractors to ensure that the end user gets a refrigeration system that is reliable, energy-efficient and that will provide customers with the best return on their investment in the market.
