GEA1August2016From October 11 to 13, 2016, Chillventa will turn the trade show fairgrounds in Nuremberginto an international meeting point for the world of refrigeration, HVAC, and heat pumps. “Let’s create your success!” is GEA’s motto at this year’s Chillventa. Analogous to the classical Tangram puzzle with its infinite opportunities, the products and solutions from GEA offer virtually unlimited possibilities for individual customer requirements in a great diversity of applications and industries. GEA will present innovative products in its range of commercial and industrial compressors, ice generators, solutions along the entire cold chain as well as product animations in hall 7, booths 306 and 504. Furthermore the Service team is looking forward to show the comprehensive range of service for the first time and will be available during the days of the exhibition.

Efficiency enhancement with the semi-hermetic compressors in the GEA Bock HG series

The HG series of semi-hermetic compressors – the GEA Bock HG22e, HG34e, HG44e, HG56e, HG66e, HG76e and HG88e models – have now been optimized and offer top efficiency as well as optimized running quietness. These compressors profit from an efficient valve plate system, electric motors from the latest generation, and improved gas passage – which enables them to achieve optimal efficiency. The oil pump lubrication system enables a greater control range with frequency inverters.

Whereas the models already on the market have been optimized, the GEA Bock HG56e represents a completely new 6-cylinder series. The new HG56e series replaces the previous 4-cylinder HG5 series and the smallest series of the HG6 compressors. It offers greater efficiency and optimized running quietness, and its three model sizes cover the displacement range from 73.8 to 100.4 m³/h (at 50 Hz).

The compressors HG22e, HG34e, HG44e, and HG56e operate with an optimized standard valve plate design. The two series HG66e and HG76e, to be launched on the market, will feature the proven-successful mexxFlow design concept. The combination of the double lamellar ring design of the mexxFlow valve plate, featuring flow-optimized characteristics, with a cylinder head especially designed for this valve plate, has enabled an efficiency increase of the compressors by up to 20%, depending on application.

Minimum space requirement and top performance: the new GEA RedAstrum heat pump

GEA3August2016An innovation in the heat pump range will soon go into production: the GEA RedAstrum, a new series of standardized ammonia heat pumps designed for indoor installation. With this system, the refrigerant ammonia remains in the machine room. The distribution of heat to the user takes place via a water circuit, which extends the application range of the heat pump. The performance of RedAstrum and the heat it supplies, at temperature levels between 55 and 80 °C, makes it ideal for industrial applications – especially for heating water in industrial processes – or for feed of heat into nearby or remote district-heating networks. In addition to its outstanding efficiency, the RedAstrum impressively applies a further advantage: thanks to its compact design, it can be effectively installed and operated in machine rooms. Speed-controlled screw compressors contribute to low power consumption in full- and part-load conditions as well as a high COP with their optimal internal volume ratio and heat exchangers that had already been used in the GEA Blu chillers. These heat exchangers ensure very good heat transfer from the ammonia to the water circuit.

Sustainable compressor technology for natural refrigerants: the GEA Bock HG series

For subcritical and transcritical CO2 applications, GEA offers a range of compressors that now includes a displacement of 6.2 to 38.2 m³/h (at 50 Hz), with 2, 4, or 6 cylinders. These compressors are characterized by great reliability, excellent running behavior, a broad frequency band for minimal part-load requirements, slight oil carry-over, and outstanding efficiency. The semi-hermetic 6-cylinder piston compressor HG46 CO2 T, for example, is currently the largest of its kind for transcritical CO2 applications and offers long-standing field experience. In addition to its displacement up to 38.2 m³/h, it is also impressive owing to its outstanding coefficient of performance (COP). The great efficiency of transcritical GEA CO2 compressors has been confirmed by ASERCOM certification for a number of compressor models.

GEA also offers efficient solutions for hydrocarbons: the HC range (HC = hydrocarbons), with displacement of 5.4 to 279.8 m³/h, satisfies all stipulations of the F-Gas Regulation. This provides planning assurance to plant contracting companies, operators, and investors. In addition to the already optimized and well-establish model HG44e HC, GEA will present new 6-cylinder compressors for hydrocarbons: the GEA Bock HG56e HC series, with three models, covers the range with displacements from 73.8 to 100.4 m³/h. HC compressors for applications with hydrocarbons are available in an extensive displacement range, including ATEX applications, Zone 1 and Zone 2.

The GEA Grasso M series: extended portfolio for smaller capacities

GEA5August2016With its new, smaller screw compressors, GEA now rounds off its GEA Grasso M series downward by adding smaller output ratings. The former spectrum of offerings began at volumetric displacements of 471 m³/h (at 2,940 rpm) and extended to 870 m³/h. The expanded series now begins at 231 m³/h. The new small models benefit from the proven and energy-efficient design: they are engineered for the speed range from 1,000 to 6,000 rpm, which allows them to cover a broad load range. The internal volume ratio (Vi) can be controlled in an extended range, which allows energy-optimized operation even at reduced condensation temperatures.

In addition, the pressure-activated check valve ensures minimal pressure drop on the suction side. The GEA Grasso M series furthermore offers an integrated suction filter and an adaptive coupling casing, which simplifies integration into a package. The GEA Grasso M series represents the development of an industrial screw compressor that differs above all from conventional screw compressors in reliability and efficiency.

The GEA Splitpack – a GEA Geneglace ice generator and GEA Bock Plusbox, perfectly matched

The GEA Splitpack combines the GEA Geneglace ice generator with the GEA Bock Plusbox to provide a complete solution. The split system allows the ice generator to be installed on the shop floor, near the process. In contrast, the Plusbox, a complete outdoor condensing unit, is installed outside at a distance of up to 20 m from the ice generator.

GEA6August2016The Plusbox features proven semi-hermetic GEA piston compressors, with maximum displacements of 18.8 to 33.1 m³/h. A speed-controlled fan at the condenser ensures efficient ice production, even with high outdoor temperatures, since it assures a constant temperature of condensation. The GEA Splitpack operates with the refrigerants R404A or R134A and is available with GEA Geneglace ice generator F15, F30, F90H, or G100. Maximum production is 400 to 2,200 kg/day, depending on the ice generator used.
