Peak Performance for the Entire Control Range

HBS screw blow­ers set a new bench­mark in com­pres­sor tech­nol­o­gy for the 132 to 250 kW pow­er range, with flow rates from 60 to 160 m³/min and dif­fer­en­tial pres­sures up to 1100 mbar. These pow­er­hous­es not only fea­ture excep­tion­al con­trol char­ac­ter­is­tics, qui­et oper­a­tion, opti­mised foot­print and low main­te­nance require­ment – they also deliv­er con­sis­tent­ly high effi­cien­cy across the entire con­trol range.
The effi­cien­cy of the HBS screw blow­er remains con­sis­tent across the entire con­trol range, not just at cer­tain spe­cif­ic lev­els, which will make this machine an espe­cial­ly attrac­tive alter­na­tive to tur­bo com­pres­sors. This new screw blow­er for the low-pres­sure range draws on Kaeser’s many decades of exper­tise in the devel­op­ment of high­ly effi­cient rotary screw com­pres­sors and automa­tion tech­nol­o­gy, through to smart machines, in order to meet the needs of Indus­trie 4.0 envi­ron­ments. The new screw blow­ers from Kaeser are up to 35 per­cent more effi­cient than con­ven­tion­al rotary blow­ers and also deliv­er sig­nif­i­cant ener­gy advan­tages com­pared to many screw blow­ers and tur­bo com­pres­sors avail­able on the market.
The blow­er block of the HBS screw blow­er is dri­ven by a loss-free direct dri­ve, mean­ing the HBS com­bines high­ly effi­cient oper­a­tion with low main­te­nance require­ment. In addi­tion, these machines are designed for space-sav­ing instal­la­tion and excep­tion­al­ly qui­et operation.
A fre­quen­cy con­vert­er is inte­grat­ed for dynam­ic adjust­ment of the flow rate to actu­al demand. More­over, the fre­quen­cy con­vert­er and motor are specif­i­cal­ly coor­di­nat­ed to deliv­er con­sis­tent­ly opti­mal over­all efficiency.
As assur­ance that the pre­dict­ed high sav­ings are actu­al­ly achieved, Kaeser guar­an­tees the pow­er con­sump­tion per unit of flow rate (spe­cif­ic pow­er con­sump­tion in kW per pro m³/h) in accor­dance with the nar­row tol­er­ances of ISO 1217, Annex E. Cus­tomers there­fore enjoy the peace of mind that comes with ensured accu­ra­cy of the pro­ject­ed sav­ings and amor­ti­sa­tion periods.
The inte­grat­ed Sig­ma Con­trol 2 con­troller ensures oper­a­tional reli­a­bil­i­ty and smart com­mu­ni­ca­tion via inte­gra­tion into process con­trol sys­tems, includ­ing those with Indus­trie 4.0 require­ments. The Sig­ma Air Man­ag­er 4.0 mas­ter con­troller is rec­om­mend­ed for blow­er sta­tions with mul­ti­ple blow­ers as it fea­tures con­trol and reg­u­la­tion algo­rithms spe­cial­ly devel­oped for the needs of low-pres­sure appli­ca­tions. This enables even greater ener­gy sav­ings and sim­pli­fi­ca­tion of automation.
Appli­ca­tions with espe­cial­ly high ener­gy require­ments, such as pro­duc­tion of aer­a­tion air for waste­water treat­ment and biore­ac­tors, as well as for flota­tion and flu­idi­s­a­tion, are sure to ben­e­fit from this advanced automa­tion and com­pres­sor tech­nol­o­gy from Kaeser.
