Static process, optimum efficiency
PENTAIR series membrane dryers are designed for low-flow compressed air networks requiring a pressure dew point between +15 and -40°C.
These dryers are completely static. They operate without a power supply and generate no condensate. Their compact size makes them particularly suitable for installation inside production machines. They are ideal for end-of-line over-drying of equipment requiring a dew point lower than the general air quality on site. The range comprises 6 models and covers flow rates up to 110 m3/h.
Important: The compressed air at the inlet to membrane dryers must be perfectly filtered, de-oiled and free of condensate. In the case of lubricated compressors, an additional activated carbon filter is recommended to protect the membrane from oil vapours.
(*) 1) Flow rates indicated in m3 /h at 1.013 bar absolute, 40°C compressed air inlet, 7 bar relative pressure, pressure dew point +5°C. (2) Flow rates indicated in m3 /h at 1.013 bar absolute, 35°C compressed air inlet, 7 bar relative pressure, pressure dew point +3°C. Minimum air quality required at dryer inlet: filtered to 0.01 ppm and 0.01µ
PENTAIR series membrane dryers use advanced selective separation technologies on polymer membranes to separate water vapor from compressed air.
Air circulates inside thousands of hollow, pressure-resistant, membrane-coated fibers. This ultra thin film membrane - patented technology - lets water molecules pass more than 20,000 times faster than air molecules. A small part of dry compressed air is taken at the outlet and injected against the current on the external part of the membranes in order to reject the water vapor outside the hull. This completely static process requires no external energy source and makes these dryers particularly attractive.
