Market leader Sabroe has always been at the forefront of new developments in industrial refrigeration, with a focus on efficiency, reduced energy consumption and minimal environmental impact. In 1990, Sabroe launched the first reciprocating compressor for high-pressure operation, and has subsequently also investigated other new areas for applying high-pressure technology. This research led to the reintroduction of carbon dioxide (CO2) in a wide range of industrial refrigeration installations with evaporating temperatures below -35°C. CO2 is not chemically active, is non-flammable, non-toxic and does not contribute to ozone depletion It therefore fulfils all the key requirements for a financially viable, future-compatible refrigerant. The first modern CO2 installation for industrial refrigeration was put into operation by Sabroe five years ago and has proved to be a great success. At the IKK 2004 trade fair (the International Trade Fair for Refrigeration, Air Conditioning and Ventilation), Sabroe will be presenting the unparalleled high-pressure reciprocating compressor that uses CO2 as refrigerant. This Sabroe HPC compressor provides an extremely compact, efficient alternative for customers in search of refrigeration equipment for use in low temperatures. This is because a CO2 compressor has a capacity 8–12 times greater than similar units with traditional refrigerants, making the low-temperature compressor much smaller, and the whole unit significantly more compact. The Sabroe HPC compressor operates at a pressure of up to 40 bar. This high pressure makes it possible for customers to exploit the benefits of using CO2 as refrigerant to an even greater extent. Forward-looking companies throughout the world are rapidly introducing CO2 in their installations, to exploit the advantages of this natural refrigerant. A refrigeration compressor that uses CO2 also provides the following clear benefits • up to 45% reduction in power consumption compared with alternative solutions • a compressor on the CO2 side needs only 10% of the swept volume compared with ammonia at the same temperatures • up to 33% more freezer capacity due to shorter freezing time • improved product quality due to quicker freezing • low installation costs For further information, please contact Mr Torben Ude Petersen, Director Sales, Marketing & Engineering +45 87 36 72 16 or at Torben.Ude.Petersen(at)remove-this.jci.com.
