Chillventa 2010 in Nuremberg - Cooly thought-out

This ACR Compressor functions with operational pressure up to 130 bar. These characteristics make it ideal for application in supercritical CO2 systems in refrigeration facilities or in heat pumps.

The new safety valves from the company GEA AWP: thanks to their response pressure of 63 bar, they are particularly effective for CO2 refrigeration plants.

GML heat exchangers are designed for high pressure applications and therefore suitable for CO2 refrigeration systems.

The AU Range was developed for slaughterhouses. The cooling stream of air is directly guided to the product hanging below.

GEA Refrigeration Technologies and GEA Heat Exchangers at Chillventa 2010 in Nuremberg - 13 to 15 October 2010, Hall 4, Stand 4-318

Bochum, Germany, 24. August 2010 – At the Chillventa trade fair in October, GEA Refrigeration Technologies and GEA Heat Exchangers, both Segments of GEA Group, will show technical innovations for cooling, climate control, and heat exchange – well as the ways that synergism develops in the Group.

GEA Refrigeration Technologies
specializes in industrial refrigeration systems for the food and beverage industry, maritime applications, the oil and gas industries, building services, and leisure facilities. Thanks to their increasing use of natural refrigerants such as NH3 and CO2, as well as enhanced energy efficiency, these systems contribute to greater climate protection in industrial processes.

One example is the ACR Compressor from GEA Grasso (see illustration), with up to 130 bar of operating pressure for transcritical CO2 systems. This product opens new possibilities for refrigeration technology and for heat pumps, and has already proven satisfactory in practice. This new compressor is employed in the HHS 1000 heat pump from the thermea company – a solution that, on the basis of its energy efficiency, received the 2009 Refrigeration Prize of the German Federal Ministry for the Environment.

One example for maximum efficiency with a minimum of operating expense is provided by the reciprocating compressors in the V Range. These compressors were optimized for low life-cycle costs: 
made possible by lowered energy consumption and halving of oil usage with respect to predecessor models, as well as by optimization of maintenance intervals and cost with the aid of their Maintenance Monitor. Because of the great demand for models V700 and V1100, the V Range is being expanded by adding two further models with greater compression duty. These models, the V1400 and V1800, will be available beginning in 2011. Planning is also for rounding off the GEA Grasso V Range toward lower duty levels. In addition, preparations are being made to place dual-stage models on the market within the coming years.

With its latest range of AWP Safety Valves (see illustration), GEA contributes to the trend toward environmentally benign refrigerants. These valves offer response pressures of up to 63 bar, compared to a maximum of 28 bar for their predecessor range. As a result, these new valve fittings are optimally suited for CO2 refrigeration systems, since compressors with the natural refrigerant CO2 operate at pressures substantially greater than with compressors using conventional refrigerants. With respect to selection of materials and effectiveness of seal, GEA developers have also taken into account the medium CO2 in order to achieve greater efficiency and long service life. The new valve fittings are available in the version AWP SVA as backpressure-dependent valves, and as version AWP SVU as backpressure-independent models.

The GEA Heat Exchangers Segment will show selected product models to demonstrate how environmental friendliness can go hand in hand with an increased process profitability.

In accordance with trends in its sister Segment, GEA Heat Exchangers offers new brazed plate heat exchangers. Produced by GEA PHE Systems the GML Range (see illustration) is designed for high pressure applications and therefore suitable for CO2 refrigeration systems.

The GEA Goedhart heat-exchanger solutions are directed to other applications. The AU Range (see illustration) was developed for slaughterhouses. These coolers are designed to be suspended from ceiling rails, and their cooling stream of air is directly guided to the product hanging below. This assures great cooling effects with low energy consumption and contributes to meat production with a minimum of pathogens.

For application in fruit storage facilities, GEA has developed slender Goedhart Air Coolers. They offer optimal air circulation at low temperature differences, and act against dehydrating effects in fruit and the rooms in which it is stored. Electronically commutated motors assure power-economical operation.

In the area of climate control of computer centers, GE offers with its Denco Range solutions for the particular requirements in this field. Denco systems ensure constant temperatures and humidity in climate-controlled rooms: 
e.g., in IT facilities. In the new Denco models being presented at Chillventa, developers have minimized internal pressure drop on the water and air sides. The result is reduction of fan energy consumption by approximately 50 %. When employed in high-performance service environments, the combination of climate-control facilities with an automatic pressure-controlled system provides exact regulation and optimization of the pressure prevailing under raised floors. This solution enables further reduction of power consumption and effectively prevents the dreaded hot spots in a server suite.
