Description
Ecodry K-MT 10-95 Efficient compressed air adsorption dryers
K-MT 10-95 heatless adsorption dryers are designed to dry industrial compressed air reliably and efficiently down to a pressure dew point of -70 °C. The units are constructed in a compact manner and designed to be free-standing. They are equipped with built-on pre- and after filtration and are sized for volumetric flows of up to 940 m³/h (suction capacity of the compressor referring to a compression of 7 bare).
Compressed air first enters the validated GL pre-filter. Continuing on, the air flows into one of two twin-vessels; both filled with molecular sieve – a renowned drying-agent, where the air is dried. During the drying process, the second vessel undergoes regeneration: At the start of the drying-cycle, this vessel is open to atmosphere and a small proportion of dried compressed air passes through the adsorption bed, transporting the humidity out. When this procedure is complete, the vessel is re-pressurized in readiness to repeat the drying procedure. Continuous, uninterrupted operation is maintained utilising so-called pressure-swing technology together with individually operated main- and exhaust valves. Dry compressed air finally exits via a validated GL after-filter preventing the migration of particles into the downstream compressed air network.
The K-MT 10-95 adsorption dryer series operates a fixed, timed, changeover-cycle between the two dryer vessels. Where the application calls for a unit able to cope with variations in operating pressure and load, the installation of a dew point sensor at the outlet of the dryer is available as an option: In such an operating mode, the changeover-cycle between vessels only takes place when required, and is dependent on the required dew-point being achieved: Only on reaching this adjustable set-point does changeover to the pre-dried vessel occur. This feature enables the drying phase to be lengthened and thus avoids the unnecessary use of purge air for regeneration. Compressed air can be selectively dried to meet a dew point of -25 °C up to -70 °C.
