Carrier efficiency boost for CO2 racks

GERMANY: Carrier Commercial Refrigeration’s new CO2 efficiency booster skid is said to offer an energy efficient upgrade for refrigeration racks.

The CO2OLtec CO2 efficiency booster skid is said to have been engineered to deliver a reduction in energy consumption of up to 10% compared to conventional CO₂ booster systems, whether equipped with or without an eco-compressor. 

It is said to rely on its ability to optimise semi-flooded mode, allowing cabinets and cold room evaporators to operate with increased efficiency while reducing defrost need. Payback is said to range from one to three years.

Tailored to cover the capacities of all food retail projects, the CO2 efficiency booster skid comes in a range of sizes and takes up less than one square metre of floor space.

The unit is said to seamlessly integrate with Carrier’s MiniCO2OL or MaxiCO2OL racks or existing racks from other brands, making it a versatile solution for both new projects and retrofits.

With a high-standstill pressure design of 60bar, the CO2 efficiency booster skid is also available with a lower rated pressure relief valve to adapt to the site. Its design incorporates a liquid ejector on medium temperature modules and a liquid/gas heat exchanger for low temperature modules.
