Industrial Refrigeration

Industrial refrigeration provides cooling for large scale processes. Ammonia systems are a well established solution for industrial refrigeration due to their superior energy efficiency and ability to chill to very low temperatures.

Ammonia has been used in the industrial refrigeration market for many decades. Recently developed low change ammonia systems are helping to address safety concerns. Propane and carbon dioxide are also used for cold storage applications with popularity increasing for cascade systems using carbon dioxide and ammonia.

Beginning in 2002, the British supermarket chain ASDA had Star Refrigeration replace all refrigeration units that use the hydrochlorofluorocarbon (HCFC) R-22 at its distribution centres as part of a long-term modernization program. Star Refrigeration designed an ammonia/CO2 cascade system. At one of ASDA’s major distribution centers in Lutterworth, UK, the refrigeration system provides efficient refrigeration for the 270,000 m³ premises. Areas requiring refrigeration are: a frozen food cold store at -25°C and several chill rooms at temperatures between 1°C and 13°C. The chill rooms are cooled with carbon dioxide as a volatile secondary refrigerant.

Reported energy savings of 10%.

Axima Refrigeration has developed an advanced ammonia cooling system for the Belgian Ice cream Group (BIG). BIG, as an ice cream manufacturer, is part of an industry that relies on superior cooling. Following pasteurization and homogenization, a mixture of cream, sugar and other ingredients is frozen and beaten up to ice cream in continuous freezers. The finished products, from cones and desserts to sorbets are sent to ducts for ultra fast freezing, after which they are packed. They are then placed in freezer storage (over 90,000 m²) at a constant temperature of -30°C. Axima Refrigeration was the first in Belgium to use a Powerdrive frequency converter with a permanent magnet synchronous motor during the installation of a new screw compressor at BIG, giving 10% better energy efficiency.

CO2 refrigerant is being used to provide cooling at Bergen Harbour’s Ship Terminal in Norway, previously cooled by an R-22 system. The UNESCO World Heritage site uses the refrigerant to provide cooling for 44,132ft2 of chilling and freezing areas, located on the mezzanine on the landsides for cargo from the ships. Heat waste from the systems is then recovered to provide heating in the terminal and offices.
