GEA Heating & Refrigeration Technologies continues to expand its semi-hermetic product portfolio. Two new screw compressor models, the GEA CompaX 350 and 400, will be launched in the second quarter of 2022. GEA is also launching the brand-new 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.
The two GEA CompaX 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. They combine the best efficiencies by using the natural refrigerant ammonia, a wide, stepless adjustable, variable internal volume ratio, and a wide speed range as well as the highest safety and reliability through decades of experience in developing screw compressors. The compact design and the simultaneously high degree of integration also make the GEA CompaX a cost-efficient and space-saving product.
In the introductory phase, the new GEA CompaX 350 and 400 models are available as both packages and chillers. The new GEA Grasso X semi-hermetic screw compressor packages are offering maximum flexibility and efficiency with a minimum footprint and overall cost. 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 a parallel arrangement.
Combined with the wide speed range of each screw compressor, the GEA Grasso X setup provides industry-leading availability, redundancy, and efficiencies at the highest level over nearly the entire full and part load range. Refrigeration capacities range from approximately 200 to 1,900 kW (NH₃, -10/+35 °C).
The existing GEA BluX semi-hermetic chiller series is also extended by the new compressors. GEA 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. With refrigerant inlet and outlet temperatures of +12/+6 °C and condensing at ambient temperatures (+35 °C), the GEA 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. Larger capacities are covered by the GEA BluX with the existing large CompaX 700 and 900 types.
"The compact, safe and reliable products in combination with their high efficiency lead to reduced total costs and a most sustainable solution," says Ron Hoffmann, product manager for screw compressors at 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. 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."
The new GEA CompaX series and the other product lines described are developed by GEA Heating & Refrigeration Technologies.
