Energy Efficiency Air Drying Process for Dehumidification Applications

Bryan Kilgore for Zondits, April 6, 2015

A new, high efficiency, dehumidification process has been developed by Nanocap Technologies using capillary condensation and osmosis through a semi-permeable membrane. Compared to typical refrigerated drying, this new air-drying process uses 20%‒35% less energy. Additional benefits include isolation of humidity and cooling control, and lower costs. This process of air drying has the potential for various end users, including commercial, industrial, residential buildings, and air conditioners used in automobiles. Nanocap Technologies will initially be licensing this technology for use in dehumidification processes.


Nanocap Technologies Develops Revolutionary Air Drying Process for Air Conditioning Systems and Other Dehumidification Applications

PRWeb, March 5, 2015

Nanocap Technologies, LLC ( announces the Nanocap Process, which uses capillary condensation and then osmosis through a semi-permeable membrane to dry air. Based on nanopore technology and available for immediate licensing, this green process is considerably more efficient than the current method of dehumidification – in use since 1902! The current system squanders a large amount of energy by cooling air down to the dew point to get water vapor to condense and drip off refrigerated coils. It then heats the air back up to a comfortable temperature. Nanocap’s transformative process avoids wasting energy to cool and reheat the air. The Nanocap Process may be viewed here:

Energy Savings

  •     Energy savings of 20-35% expected during typical air conditioning use
  •     Air is pre-dried, separate from the cooling process
  •     There is no need to cool air to the dew point and then reheat it to comfortable temperatures
  •     Air conditioning would be used much less in cool, high humidity weather
  •     Helps meet current and future government-required efficiency standards

Increased Customer Comfort and Satisfaction

  •     Lower operating costs
  •     Humidity control is independent of cooling so air is neither too warm nor too cold
  •     “Comfort-stat” will have humidistat and thermostat controls for individual comfort
  •     Air won’t be “muggy” in very humid spaces, including exercise rooms, schools, and convention halls
  •     Noise levels are significantly reduced
  •     Environmentally friendly

Lower Production Costs

  •     Condensers and compressors are smaller so air conditioners are cheaper to produce
  •     Standard air conditioning cycle is used to cool dehumidified air
  •     Dehumidifier may be incorporated in air conditioning systems either as embedded technology during the manufacturing process, or as a simple retrofit to existing systems
  •     Essential components are commercially available
  •     Polymer membranes are flexible, compact, and inexpensive
  •     Membranes are long-lasting and do not degrade
  •     Using membranes and salt solution to dehumidify results in large cost savings
  •     Moving parts are minimized
