Van Air HI Series internally heated regenerative compressed air dryers protect pneumatic equipment and processes from the harmful effects of moisture within the air lines. Our HI Series air dryers utilize a multiple-element heater located within the desiccant tower to heat the purge air for the regeneration of the adsorbent desiccant.

Individual heater thermostats and adjustable purge flow rates allow you to adjust the HI Series heated regenerative air dryer to meet your operating requirements. Low watt density heaters contained within the desiccant towers prevent hot spots which could cause fusing and other damage to the adsorbent desiccant beads. The -40° F / C dew point achieved with a Van Air HI Series compressed air dryer virtually eliminates internal pipe corrosion, adding years to your air system piping.

Constructed and tested to the most demanding standards, our HI Series internally heated regenerative compressed air dryers are built in-house and made to last. All HI Series desiccant vessels are ASME certified. Separate valves for hot purge air prevent thermal shock and extend valve life. Standard on all HI Series compressed air dryers, our patented Interlock valve ensures the most reliable tower cycling on the market.

Factory startup, training and on-site assistance are also available. Let our experienced technicians get your compressed air system up and running hassle-free. Plus, we can train your plant personnel on the ins and outs of your dryer's operation so they can maintain this key element of your air system with confidence.
