SHA Series - Heatless Modular Desiccant Air Dryers
SHA Series - Heatless Modular Desiccant Air Dryers
Product Type:
DRYERS - COMPRESSED AIR / DESICCANT COMPRESSED AIR DRYERS
SHA Series Modular Desiccant Air Dryers are ideal for point of use, laboratories and confined areas. They provide a continuous supply of dry compressed air by automatically cycling the flow of air through two desiccant beds.
FEATURES
Hankison’s HSHD Series Modular Desiccant Air Dryers protect moisture sensitive applications requiring low-pressure dew points. Delivers dew points of ISO 8573-1: 2010 Class 1 (-100°F, -70°C) and Class 2 (-40°C) with flow rates of 7 to 40 scfm (12 to 68 nm3/h). Critical applications include labs, hospitals, pharmaceutical manufacturing, and other high-tech installations.
The HSHD Series Dryers incorporate a time-proven design, with superior features and reliability, in a compact and easy to install package. Standard features include:
THEORY OF OPERATION
Compressed air enters the dryer and is directed to Tower 1 by valve (A), and then to the dryer outlet through shuttle valve (B). A portion of the dried air is throttled to near atmospheric pressure by means of orifice (C). This extremely dry, low-pressure air flows through and regenerates the desiccant in Tower 2 and is exhausted through purge/repressurization valve (D) and exhaust muffler (E) to atmosphere. After a set time, the automatic solid state timer closes purge/repressurization valve (D) allowing Tower 2 to repressurize slowly. At the end of 2 minutes, valve (A) shifts and purge/ repressurization valve (D) reopens. The main air flow is now dried by Tower 2 while Tower 1 is being regenerated.
