As part of VortEx compressor equipment, which is directly related to the VSD compressors series, reliable frequency converters from German manufacturers are used. Thanks to the use of frequency converters, the operation of engines at frequencies up to four hundred Herz is possible. Structurally, Vortex compressors differ in that they have a separate ventilation system for electrical equipment and for the compressor. Such an optimal solution makes it possible to operate VSD compressors in conditions of quite rigid when the ambient temperature reaches forty -five degrees in a plus scale. The development of VSD units is performed taking into account high performance, reliability, simplicity of maintenance.
