Van Gas Technologies HLSX heatless regenerative desiccant dryers are designed to protect pneumatic equipment, controls and processes from the harmful and costly effects of moisture in compressed air and natural gas lines. All electrical components on HLSX dryers are housed in explosion proof enclosures, ideal for operation in areas classified as hazardous.

Van Gas HLSX regenerative desiccant dryers operate on the principle of pressure swing adsorption, where a fraction of dry gas is used to regenerate the off-stream tower. No heat or exhaust power is required for desiccant bed regeneration. In natural gas applications, purge exhaust can be diverted to compressor suction or used as fuel.

HLSX dryers deliver a -40ºF pressure dew point with models rated for 55, 80, 120 and 150 SCFM. All models in the HLSX series have a maximum working pressure of 280 PSIG. No yellow metals are used in the construction of HLSX dryers.

For over 60 years, Van Gas Technologies has been an industry leader in absorbent desiccant, and gas dehydration and filtration technology. Please contact us today with any questions you may have or to place your order.
