GEA expands semi-hermetic product portfolio
DUESSELDORF, Germany, 17 May 2022: GEA Heating & Refrigeration Technologies said it is expanding its semi-hermetic product portfolio, with two new screw compressor models – the GEA CompaX 350 and 400 – set to be launched in the second quarter of 2022. Making the announcement through a Press release, GEA said it is also launching the GEA Grasso X semi-hermetic screw compressor packages. For the BluX chiller, there will be major technical enhancements and adaptations for optimal implementation to the compressors, it said.
The two models, 350 and 400, with a flow volume of 321 and 372 m³/h (at 2,940 rpm), extend the semi-hermetic screw compressor series from larger to medium and also smaller capacity requirements, the company said.
They combine best efficiencies by using the natural refrigerant, ammonia, a wide, stepless adjustable, variable internal volume ratio and a wide speed range as well as highest safety and reliability through decades of experience in developing screw compressors, the company claimed.
The compact design and the simultaneously high degree of integration also make the CompaX a cost-efficient and space-saving product, the company further claimed.
In the introductory phase, the 350 and 400 models are available as both packages and chillers, the company said. The new Grasso X semi-hermetic screw compressor packages offer maximum flexibility and efficiency with a minimum footprint and overall cost, the company said. Customers can choose between a single version and a multipackage. The multipackage can optionally be configured by the customer with two, three or four identical CompaX 350 or 400 units in parallel arrangement, the company added.
Combined with the wide speed range of each screw compressor, the Grasso X setup provides availability, redundancy and efficiencies at the highest level over nearly the entire full and part load range, the company claimed. Refrigeration capacities range from approximately 200 to 1,900 kW (NH3, -10/+35 °C), it added.
The existing BluX semi-hermetic chiller series is also extended by the new compressors, the company said. The BluX includes all the features and benefits of the unit. The proven, state-of-the-art heat exchanger set completes the product to a compact, highly efficient and safe plug-and-play solution, the company claimed. With refrigerant inlet and outlet temperatures of +12/+6 °C and condensing at ambient temperatures (+35 °C), the BluX capacity range extends from approximately 350 kW cooling capacity with 1x CompaX 350 at 3,000 rpm to circa 1,530 kW with 2x CompaX 400 at 6,000 rpm, the company said. Larger capacities are covered by the GEA BluX with the existing large CompaX 700 and 900 types, it added.
“The compact, safe and reliable products, in combination with their high efficiency, lead to reduced total costs and a most sustainable solution,” said Ron Hoffmann, Product Manager for screw compressors, GEA. In addition, GEA systems require a minimum of maintenance. “We like to convince our customers with the performance and efficiency figures of our machines, Hoffmann said. “We are happy to bring over 50 years of expertise in the development and production of screw compressors to the market with our proven and new products.”
