Quieter, more compact and with frequency control

Kaeser boost­ers with dri­ve pow­ers rang­ing from 22 to 45 kW are now avail­able in a com­plete­ly new design: as com­pact and space-sav­ing com­plete units opti­mised for low vibra­tion and noise emis­sions. Future ver­sions will also fea­ture option­al­ly avail­able fre­quen­cy con­trol. Many addi­tion­al enhance­ments, such as opti­mised cool­ing, fur­ther reduce over­all sys­tem and ener­gy costs.

Pre­vi­ous­ly this size of boost­er was only avail­able in con­ven­tion­al ver­sions – with­out Sig­ma Fre­quen­cy Con­trol (SFC). The new dri­ve func­tion ensures supe­ri­or har­mon­i­sa­tion of the boost­er on the input side with the upstream com­pres­sor out­put. This in turn allows for reduc­tion of the rel­a­tive­ly high switch­ing fre­quen­cy char­ac­ter­is­tic of some boost­er appli­ca­tions. It’s pre­cise­ly because appli­ca­tions do not always work with the same pres­sure that boost­ers must pro­duce sig­nif­i­cant­ly greater pres­sure than is actu­al­ly used in the appli­ca­tion. The pow­er­ful SFC func­tion­al­i­ty helps adjust the free air deliv­ery as con­sis­tent­ly as pos­si­ble to the needs of the sys­tem. This reduces switch­ing dif­fer­en­tials on both sides, as well as poten­tial­ly result­ing over­pres­sure, leaks and machine load – all of which con­tribute to ener­gy savings.

Plug & run

The dynam­ic appear­ance of the new, com­plete-unit design is not just cos­met­ic: it saves space (the foot­print has been reduced to just 2.3 m² from 5 m²) and makes main­te­nance even more straight­for­ward thanks to intel­li­gent com­po­nent lay­out. Despite their enhanced per­for­mance, the new boost­ers run notice­ably qui­eter thanks to the enclo­sure with inte­grat­ed after­cool­ing as well as the low-vibra­tion basic struc­ture. For added con­ve­nience, the boost­ers are ready for imme­di­ate elec­tri­cal con­nec­tion upon deliv­ery, there­by great­ly min­imis­ing instal­la­tion time and costs.

Controller monitoring

The inte­grat­ed Sig­ma Con­trol 2 con­troller is equipped with spe­cial boost­er soft­ware to ensure opti­mal sys­tem oper­a­tion whilst also enabling con­ve­nient con­nec­tion to mas­ter con­troller sys­tems via Eth­er­net. Since all indi­vid­ual com­po­nents can be per­fect­ly coor­di­nat­ed with one anoth­er, the entire sta­tion can be opti­mised to pro­vide max­i­mum effi­cien­cy and per­for­mance. Inte­gra­tion is also pos­si­ble with­in an Indus­try 4.0 environment.
