GEA Adia-DENCO®: short amortization periods owing to low operational costs in computer centers

The GEA Adia-DENCO® cooling system has been especially designed for HVAC use in data centers. The system, with its extremely low energy consumption, is based on the proven GEA CAIR range of air-handling units. It exploits the principle of free cooling in combination with adiabatic humidification, to effectively reject heat. On the basis of the very slight number of hours in the year with temperatures above 29 °C (e.g. in Central Europe), power consumption for compressor-based cooling is reduced to an absolute minimum. With the GEA Adia-DENCO®, data center operators can save up to 70 percent energy and can accordingly lower their operating expenses.

GEA Multi-DENCO®: precision climate-control units for constant temperature and relative humidity

At China Refrigeration GEA will show the new range of precision climate-control units GEA Multi-DENCO®. These units are designed for circulating air operation and will be available with approximate cooling duty of 5 to 130 kW. Thanks to the use of CFD simulation and inverter technology, GEA engineers succeeded in optimization of the air-treatment performance of the system, and in appreciably improving efficiency in comparison to its predecessor ranges. The new GEA Multi-DENCO® range will replace the GEA Denco T and E ranges in future.

New GEA Grasso V series: reciprocating compressors that challenge total cost of ownership

During the development of the new V series reciprocating compressors GEA Refrigeration Technologies continually put itself in the position of the end user. This resulted in one of the most efficient industrial compressors available on the market with extended as well as flexible service intervals combined with highest achievable reliability. A small standard fitted microprocessor monitors the required service intervals. The series comprises in the meantime a complete range of single and two stage (compound) models for industrial cooling and freezing applications.

GEA Maxi-Stack: freezing and chilling solution to increase product output

GEA Maxi-Stack spiral freezers and chillers by GEA Refrigeration Technologies minimize the required footprint and height as a result of their new self-stacking belt system. The robust design of GEA Q-belt™ ensures a reliable stacking system. With fully welded stainless steel floors and structures, the GEA Maxi-Stack is designed to be efficiently cleaned by a Clean-In-Place (CIP) system assuring top quality and safety for food products.

Semi-hermetic compressors: extended and optimized range

GEA Refrigeration Technologies reveals the HG46 CO2 T, biggest semi-hermetic reciprocating compressor for transcritical CO2 applications on the market. With displacements from 21,8 to 30,2 m³/h, it features an outstanding COP of over 1,85 for normal cooling.The CO2 compressor range will be rounded off by the HG12e, an efficiency-optimized version of the compact 2-cylinder compressors series.

New open type piston compressor: 8-cylinder model F18

In industrial and maritime applications, system operators often use open type piston compressors with an external drive for reliability, flexibility and operational safety. For these application fields, GEA Refrigeration Technologies presents the new GEA Bock compressor model F18, of the established GEA Bock F-series. It combines know-how of the small and medium output range with skills in the higher output series.

The F18 uses a plasma nitrocarburized crankshaft to drive its eight pistons. The compressor also features the GEA Bock mexxFlow® valve system, a flow-optimized double-ring valve plate design in combination with a special cylinder head. The system raises energy efficiency of compressors by around 15%. Currently, the F18 compressor is available for standard refrigerants. A version for the use of NH3 (Ammonia), an established refrigerant for industrial systems, will follow during 2013.

Semi-hermetic air-cooled compressors for deep-freezing

Compressors rapidly reach their temperature limits due to the rise in temperature of the suction gas caused by the drive motor resulting in a decreasing refrigeration capacity. With the GEA Bock HA principle by GEA Refrigeration Technologies, compressor suction gas is fed directly to the compressor without being diverted through the motor. The motor is cooled by an integrated ventilation unit. With precise airflow it also cools the compressor and the cylinder heads. Lower discharge gas temperatures make applications with improved refrigeration capacity (deep freezing) possible.

GEA FK series compressors for air-conditioning of buses

With the development of the Chinese bus market, more and more bus users focus on energy saving as well as cost control during the whole life of the buses. GEA Refrigeration Technologies provides the market with traditional GEA Bock FKX40/655K and FKX50 compressors, which are suitable for 11-12 meter AC buses and longer AC buses respectively. They feature compact design, strong components, include a reliable oil lubrication system, a K-Valve plate as well as a simple but reliable shaft seal system.
