The ECO CONTROL 2 controller saves considerable energy especially with variable flow rates, pressures or temperatures. The dew point trend recognition control is more cost-effective and secure than conventional dew point controllers since it reacts to changes in the desiccant temperature differential instead of responding only when the pressure dew point at the dryer outlet increases. New measurements and relative temperature differential comparisons are carried out for each new cycle. As chamber switch-over occurs only after the desiccant has been used to its full potential, the adsorption phase can be extended by up to 30 minutes, based on workload, to save purge air.
- The Kaeser system not only makes a costly pressure dew point measuring device superfluous,
- but also eliminates the associated regular calibration and maintenance costs.
- Unlike dew point measuring devices, temperature sensor functionality can be easily checked thanks to reliable open circuit monitoring.
