HI-PLEX – DUAL TECHNOLOGY DRYERS Hybrid Energy Saving Compressed Air Treatment BESPOKE DRYERS BUILT FOR YOUR APPLICATION HI-PLEX dryer system follows a two stage Drying process. First the Compressed air enters a refrigerant Dryer that reduces the Dewpoint to +3 Degrees C (approx. 80% of the incoming water loading). The remaining 20% is enough to achieve the heat of adsorption required in the Desiccant Dryer to achieve pressure Dewpoints more than -40 degC. Regeneration of the Desiccant vessels is by a vacuum/heatless process, the most straightforward method of Adsorption drying. With the pressure swing process, moisture is adsorbed in one vessel and desorbed in another simultaneously. HI-PLEX high performance dryers utilise the natural property of the high porous drying agent i.e., the fact that it is always in equilibrium (sorption) with the environment. HI-PLEX high performance Dryers use a side channel vacuum pump to strip out any moisture during the regeneration phase. A small bleed of dry air is introduced on the outlet pipework which causes a desorption effect within the desiccant. The small amount of remaining water vapour is removed by the vacuum pump via a silencer back to the atmosphere from where it came. HI-PLEX high performance Dryers use only approx. 1- 2% purge as opposed to 13% for a standard Heatless Desiccant Dryer. Considerably more savings can be achieved if Dewpoint Control (AEMS) is added to the HI-PLEX Dryer system. Hi-line Industries Ltd.
