Utilizing twin towers filled with premium grade activated alumina, Hankison Heatless dryers are available with different application-specific control systems to meet the needs of the industry with economy and performance.  

HHL Series heatless desiccant dryers provide consistent outlet pressure dew points to -70°C. 

Standard Instrumentation 

  • Left and right tower pressure gauges 
  • Purge pressure gauge 
  • Moisture indicator - alerts operator of elevated dew point 
  • The throttling valve provides accurate purge pressure adjustment. 
  • With inlet and outlet filters as standard  
  • HHL 91 – HHL 901 standard up to 16 bar 
  • HHL 1051 – HHL 9001 standard 10 bar (g) 16 bar on request   

Controller Options 

Level 1 

Pure and Simple 
HHL Series presents traditional heatless drying technology. Using a simple timer-based controller, these are designed to deliver maximum value to applications that operate at or near full capacity. Automatic time-controlled bed regeneration cycles offer consistent performance and economy of purchase. 

LX Controller 

It is a Standard SPS Controller with a PDP Sensor and an Energy Saving feature
