[X]   | Outstanding efficiency with low pressure dew points
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 currently the only compressed air systems provider to offer combination solutions in this way. If pressure dew points of <+3 °C are required for flow rates from 20 m³/min, then it is seriously worth considering the use of a Hybritec system, especially in view of the significant savings that can be achieved. KAESER’s experts are able to provide a detailed cost analysis comparison for any application and will advise the customer accordingly as to which method / system is the most efficient to meet his / her needs.

[X]   | 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. These advantage become even more pronounced with rising energy prices and shorter, less frequent periods of frost and sub-zero temperatures.

[X]   | Energy savings
Hybritec dryers can provide significant savings compared with single-stage heat regenerated desiccant dryers. With an assumed frost period of 4 months a year for example, it is possible to reduce energy costs by up 67 %. Even if the system is used to provide a pressure dew point of - 40 °C year-round, the energy saving potential can still be as high as 50 %.

[X]   | Modulating control
The modulating control systems, fitted as standard, enable additional energy savings. Digital scroll control is available for refrigeration dryers with flow rates up to 66.7 m³/min, whilst cylinder shutdown is also used to precisely control the refrigerant compressor. In addition, the desiccant dryer features a PDP sensor and a corresponding regulator to adjust cycle times.

[X]   | 3x longer cycle time
Due to the lower temperature and significantly reduced moisture content of the air coming from the refrigeration dryer, Hybritec systems require far less desiccant than conventional desiccant dryers, as the desiccant’s adsorption capacity is optimised. In fact, more desiccant is used than is actually required, because the compressed air has to maintain certain flow rates. This saves energy, as the extra desiccant considerably extends the Hybritec’s drying cycle time to 16 hours (PDP: – 40 °C); this is typically 2.7 times longer than for conventional desiccant dryers. This longer cycle time means that the drying process does not have to be switched between the Hybritec`s chambers as frequently and thereby minimises the volume of dried compressed air that is purged into the ambient surroundings each time this process takes place.
