Hankison Modernizes HPR and HPRN Series of Refrigerated Compressed Air Dryers

Hankison, a premiere brand of SPX FLOW, has streamlined the HPR and HPRN refrigerated compressed air dryers to offer flow rates of 5 – 1,200 scfm (17 to 2,040 m3/h). The updated range consists of the HPR5/10 – HPR50, providing 5/10 – 50 scfm; and the HPRN75 – HPRN1200, providing 75 – 1,200 scfm. The range also meets growing customer demand for low voltage compressor room ready refrigerated compressed air dryers, capable of 5 scfm – 150 scfm in 115 voltage, single phase power; and 200 scfm – 1,200 scfm in 460 voltage, three phase power.

The HPR and HPRN series of refrigerated compressed air dryers from Hankison, a brand of SPX FLOW.

The expanded line-up enables compressed air customers to treat a greater range of air flows than ever before, in more readily available industrial voltages, provided for by the majority of compressor room electrical infrastructures. The new HPR and HPRN Series continue to build on Hankison’s expertise in refrigerated compressed air treatment, providing optimal dewpoint performance at 0 - 100% load. As a result, the Hankison HPR and HPRN series of refrigerated air dryers achieve moisture removal to ISO 8573-1: 2010 Air Quality Class 4 to 5 pressure dew points and are certified for quality and safety to UL1995/CSA 22.2 No. 236-95.

The Hankison HPR and HPRN Series of refrigerated air dryers also have an updated user interface providing more instrumentation and control for at-a-glance readings, and the ability to conduct drain maintenance directly from the control panel, reducing maintenance time by 80% on average.

Hankison HPR and HPRN refrigerated compressed air dryers are designed and built to be long-lasting and reliable and as such are supplied with the following warranties:

  • HPR Series 5 – 10 and 15 scfm: standard one-year warranty parts and labor
  • HPR 25 – 50 scfm: standard two-year warranty parts and labor
  • HPRN 75 – 2000 scfm: standard two-year warranty parts and labor

As an extra measure of protection, customers who select a dryer with Filtration Package and the annual purchase of a maintenance kit receive an additional three years protection, parts and labor – giving five years protection and peace of mind. All major components are covered.
