HYBRITEC - Double efficiency


Outstanding efficiency with low pressure dew points
KAESER HYBRITEC dryers offer an exceptional level of standardisation for both the desiccant and refrigeration drying stages, yet ensure outstanding flexibility when it comes to providing a tailored solution in order to meet the needs of a specific application. Moreover, such standardised processes ensure consistent production quality. KAESER is the only compressed air systems provider to offer combination solutions in this way.

   Seasonal temperature profile
The HYBRITEC’s combination approach for applications requiring frost protection has clear energy advantages both over stand-alone desiccant dryers and separate components installed in series. 
   Energy-saving modulating control
The modulating control systems, fitted as standard, enable additional energy savings. Digital scroll control is used with the refrigeration dryers, whilst cylinder shutdown is also used to precisely control the refrigerant compressor. Desiccant dryers feature a PDP sensor and a corresponding regulator to adjust cycle times.
   Long desiccant service life
As the air entering the desiccant dryer section has already been dried to a PDP of +3 °C, it burdens the desiccant to a far lesser extent than untreated compressed air. Desiccant service life of up to 10 years is therefore possible as a result and consequently reduces costs.

   10-year desiccant service life
The reduced thermal and mechanical demands that are placed on the HYBRITEC's desiccant dryer section not only significantly extend desiccant service life, but also mean that less desiccant material is actually required. Service costs are therefore kept to an absolute minimum.
