We’ve used ADT across a few different projects. What keeps us going back is they actually know how our sites work, and work with us to find the best solutions.

Heatless regenerating adsorption dryer
HPSA Heatless Desiccant Air Dryers
- One Year Warranty (parts & labour)
- Electrical Panel to 17th Edition IEE Regs
- Stainless Steel Pipework
- Independent Switching Valves
Product detail
Everything you need to specify
This proven technology is designed and built in Burton-upon-Trent factory by a highly skilled team of engineers working to EU engineering standards.
HPSA dryers are sold as “Plug and Play” and come skid mounted with their own filtration package with pre and after filters as standard.
These dryers use positively driven valves and full flow non-return valves and have no shuttle valves as fitted within inferior quality dryers.
Designed for a long trouble free service life, each HPSA uses Dri-Zorb 27 desiccant media which delivers constant low dewpoints whilst using the lowest possible amount of regeneration air.
The digital control panel which has LED display as standard, can be upgraded to include digital dewpoint display and dewpoint control. It can communicate with most BMS systems and compressors for automatic stop/start or timed duty.

Why it matters
Clean, dry air pays back
The right filtration and drying shows measurable returns across the whole facility.
– Air loss
20-30%
Reduction in total air loss when leaks are properly sealed and repaired.
British Compressed Air Society
– ENERGY SAVINGS
~7%
Energy savings per bar of pressure drop recovered when filters are clean & dryers cleared
Hayley Dexis
– ELECTRICITY REDUCTION
10-15%
Electricity reduction as compressed air accounts for up to 30% of a facility’s total electricity bill
British Compressed Air Society
– INCREASED LIFESPAN
20-30%
Increase in the lifespan of pneumatic tools. Clean, dry air prevents this internal wear and tear.
