Three Hankison Technology Platforms for HPRplus and HES Series Refrigerated Dryers

Since L.E. Hankison patented the Condensifilter, (forerunner to the refrigerated air dryer) in 1943, Hankison International's engineers have set the industry standard for refrigerated dryer technology.

A Reliable 38°F (3°C) Pressure Dew Point-There is a Difference!

An advanced Multi tubes-in-tube design offers three times more surface per unit length than other designs. Splitting the air flow into multiple tubes enhances teh heat transfer rate which provides the thermal cooling nexessary for consistent 38°F (3°C) dew points.

Many under-sezed modular heat exchanger designs, which have been borrowed from commercial applications, do not provide sufficient thermal cooling. At 1000 scfm, the difference between a 38°F (3°C) and 60°F dew point can result in 75 gallons of liquid water going downstream....every week. Be wary of performance claims that do not guarantee a pressure dew point (vs. a "lowest air temperature" claim).

Reduce Capital and Operating Costs by using Hankison Smooth-tube Designs

Compressed air poses a unique challenge to heat exchangers in the form of high inlet concentrations of airborne contaminants such as dirt and rust scale. These particles can potentially block the head exchanger causing costly increases in pressure drop and require the installation of additional pre-filtration.

Hankison-design heat exchangers feature smooth-tube, copper heat exchange durfaces which are non-fouling. Airborne contaminants have no place to get trapped and are swept through the heat exchanger by the compressed air.

Hankison heat exchangers do not require pre-filters. Every filter added to an installation adds to pressure drop costs. Many heat exchangers, originally designed for commercial refrigeration applications, require pre-filtration which increases capital and operating costs. This is because the narrow air paths present many surfaces to which airborne contaminants can adhere themselves to over time.
