GEA Heating & Refrigeration Technologies is expanding its semi-hermetic product portfolio. The company will launch two new screw compressor models, the GEA CompaX 350 and 400. In addition, it has announced new GEA Grasso X semi-hermetic screw compressor packages. And in the case of the Blu X chiller, there will be significant technical improvements and adaptations for the optimal implementation of the compressors.

The two models, GEA CompaX 350 and 400, with a volume flow of 321 and 372 m³/h (at 2,940 rpm), expand the semi-hermetic screw compressor range from large to medium and also to the smallest capacity requirements. They combine the best efficiencies through the use of ammonia as a natural refrigerant, a wide and wirelessly adjustable variable internal volume ratio and a wide speed range, as well as the highest level of safety and reliability through decades of experience in the development of this type of compressor. The compact design combined with the high degree of integration also make the GEA CompaX a cost-effective and space-saving product.

In the introductory phase, the new GEA CompaX 350 and 400 models are available as packages and chillers. These new GEA Grasso X semi-hermetic screw compressor packages offer maximum flexibility and efficiency with minimal overall footprint and cost. Customers can choose between a single version and a multipackage. The multipackage can optionally be configured with two, three or four identical CompaX 350 or 400 units in a parallel arrangement.

In combination with the wide speed range of each screw compressor, the GEA Grasso X configuration provides industry-leading availability, redundancy and efficiency at the highest level over almost the entire full and part load range. Cooling capacities range from approximately 200 to 1,900 kW (NH3, -10/+35 °C).

New compressors

The existing GEA Blu X semi-hermetic chiller series is also expanded with the new compressors. GEA BluX includes all the functions and advantages of the unit. The proven set of state-of-the-art heat exchangers completes the product with a compact, highly efficient and safe plug-and-play solution. With refrigerant inlet and outlet temperatures of +12/+6 °C and condensation at room temperature (+35 °C), the capacity range of the GEA BluX extends from approximately 350 kW cooling capacity with 1x CompaX 350 at 3,000 rpm to around 1,530 kW with 2x CompaX 400 at 6,000 rpm. The larger capacities are covered by the GEA Blu X with the existing large CompaX 700 and 900.

"The compact, safe and reliable products in combination with their high efficiency result in lower total costs and a more sustainable solution," says Ron Hoffmann, GEA Screw Compressor Product Manager. In addition, GEA systems require very little maintenance. "We like to convince our customers with the performance and efficiency figures of our machines. We are proud to have more than 50 years' experience in the development and production of screw compressors on the market with our time-tested and new products".

The new GEA CompaX series and the other product lines described are developed by GEA Heating & Refrigeration Technologies.
