HLK SERIES
Pressure Swing Desiccant Air Dryers
HLK 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.
Share
- Consistent outlet pressure dew points Large desiccant beds produce, -40(℃) pressure dew point
- Minimum purge air usage-saving the heat of adsorption maximizes the moisture holding capacity of the purge air, minimizing the amount required
- Long desiccant life-beds sized to prevent fluidization plus slow and complete regeneration prevent desiccant movement and deterioration
- Heavy duty purge exhaust muffler for quiet operation
- Non-lubricated, soft seated control valves
- Stainless steel support screens and air diffusers-filters out gross contaminants, protects valves
- Furnished in cabinet for easy wall mounting completely assembled, piped, and wired shipped with full charge of desiccant only hook-up of utilities is needed to operate
- Vessels are constructed to meet the requirements of ASME code, Section Ⅷ, Division 1 and stamped (55 scfm larger)
Shuttle Valve-HL 10K-HL600K
- Consistent outlet pressure dew points Large desiccant beds produce, -40(℃) pressure dew point
- Minimum purge air usage-saving the heat of adsorption maximizes the moisture holding capacity of the purge air, minimizing the amount required
- Long desiccant life-beds sized to prevent fluidization plus slow and complete regeneration prevent desiccant movement and deterioration

Wall Mount Dryer-HL 10K-HL35K
- Stainless steel support screens and air diffusers-filters out gross contaminants, protects valves
- Furnished in cabinet for easy wall mounting completely assembled, piped, and wired shipped with full charge of desiccant only hook-up of utilities is needed to operate
- Vessels are constructed to meet the requirements of ASME code, Section Ⅷ, Division 1 and stamped (55 scfm larger)
- Compressed air enters the dryer and is directed to vessel 1 by valve and then to the dryer outlet through shuttle valve. A portion of the dried air is throttled to near atmospheric pressure by means of orifice.
- This extremely dry, low pressure air flows through and regenerates the desiccant in vessel 2 and is exhausted through purge/repressurization valve and exhaust muffler to atmosphere.
- After a set time, the automatic solid state timer closes purge/repressurization valve allowing vessel 2 to repressurize slowly.
- At the end of 5minutes(when operating on a 10minute cycle, 2minutes on a 4minute cycle), valve shifts and purge/repressurization valve re-opens. The main air flow is now dried by vessel 2 while vessel 1 is being regenerated
