BERLIN, Germany, 14 October 2020: GEA said it has increased the maximum top speeds for several of its reciprocating and screw compressors. The reciprocating compressor models, GEA Grasso V 700, V 1100, V 1400, and V 1800, formerly at maximum speed of 1,200 rpm, can now be operated with NH3 up to 1,500 rpm, GEA claimed through a Press release. For GEA Grasso LT screw compressor types R, S, and T, the allowable speed for NH3 will increase from a previous maximum of 3,600 rpm to 4,500 rpm, the company said.

The respective compressor models, like their smaller-sized counterparts, are and have been designed for higher speeds in the first place, the company said. The V 700, V 100, as well as the LT type R are integrated in the company’s Blu chiller series and have been running successfully at 1,500 rpm and 4,500 rpm respectively for 10 years already, it said. Additionally, intensive, long-term tests of all models have shown that they can be operated at 1,500 rpm and 4,500 rpm, respectively at the same reliability and without additional engineering or maintenance efforts, the company said. The release of the new maximum speeds, therefore, applies to bare compressors and to packaged compressor unit, too, it added.

The speed increase provides clients with a significant increase in capacity, the company claimed. Owing to the proportional correlation of compressor speed, swept volume and resulting capacity, 25% more capacity can now be gained using the same models with the same financial outlay, it claimed. That returns a significant improvement (reduction) of the relative price, as in Kilowatts per Euro, because the additional investment required is in the single-digit range, it said.

Looking at this from a different angle, users with a specific, fixed capacity requirement can benefit from the higher speeds by allowing them to achieve the capacity demands with smaller compressor equipment, meaning less investment and less service expenses, the company said.

Higher speeds, without more frequent service intervals, the company said, enables its customers the use of smaller compressors and the reduction of total costs of ownership. Screw compressors, in addition, can be regulated better in a wider speed range, returning improved part-load efficiencies, it said.

Higher speeds, GEA said, enables its customers the use of smaller compressors and a reduction of initial investment cost. On multiple stack orders, it said, customers can save up to 20% on footprint, construction, piping and electrical arrangement costs.
