Have a lower initial cost than heated type dryers. Simple and reliable due to no heaters or blower to maintain. No thermal or dew point spikes after tower switch over and ensure 4.8 seconds contact time plus 30% extra desiccant provided consistent outlet pressure dew point and temperature is easy available. To world standard of ISO 8573.1.
For different P.D.P. requirement we design 4min/10 min cycle mode. 10 minute cycle produce -42 . 4 minute cycle produce -72 . (outlet concentrations of 1 ppb @ 7kgf/cm2 )
It takes about 72 hours to reach required P.D.P. when first use.
Standard Purge Economizer ( 25%~100% ) is able to match purge air use to the demand on the dryer.
Tower design saves 98% of the heat of adsorption helps to minimize purge air required -13.5 % minimum purge air use, the lowest in the industry.

FAQs of Heatless Desiccant Compressed Air Dryer:

Q: How does a heatless desiccant compressed air dryer operate?

A: This dryer utilizes a pressure swing adsorption (PSA) process where compressed air passes through a vessel containing activated alumina or silica gel desiccant. The desiccant adsorbs moisture, delivering dry air with dew points as low as -40C (or optionally down to -60C). Regeneration occurs without heat; a portion of dried air purges moisture from the off-line vessel, enabling continuous operation.

Q: What are the benefits of using a heatless desiccant air dryer in industrial applications?

A: Heatless desiccant air dryers provide reliable moisture removal, protecting sensitive equipment and processes from corrosion, contamination, and operational issues. Their low-maintenance, energy-efficient design (no external heating required) makes them cost-effective for industries demanding high air quality, such as pharmaceuticals, paint shops, and food processing facilities.

Q: When should I consider installing a heatless desiccant compressed air dryer?

A: Install a heatless desiccant dryer when your compressed air systems require ultra-dry air with dew points of -40C or lower to prevent moisture-related damage in end-use applications. This is particularly important in critical operations like chemical manufacturing, electronic assembly, and automotive spray painting, where even slight condensation can compromise product quality or cause equipment failure.

Q: Where can this type of dryer be installed and what are the installation requirements?

A: These dryers are designed for indoor, floor-mounted installation in industrial environments with ambient temperatures ranging from 5C to 50C. They connect easily to air systems via NPT/BSP threaded connections (from 1/2" up to 4" sizes, depending on the model). Ensure location has adequate clearance for maintenance and is close to a 220V AC, 1-phase, 50Hz power supply.

Q: What is the maintenance process for a heatless desiccant compressed air dryer?

A: Routine maintenance primarily involves inspecting and replacing the desiccant (activated alumina or silica gel) as per manufacturers guidelines, cleaning filters, and periodically checking the control system for any faults. Regular maintenance ensures optimal dew point performance and extends the dryers service life.

Q: What applications benefit most from this technology?

A: Industries requiring consistently dry, contaminant-free compressed airsuch as pharmaceuticals, food processing, chemical plants, automotive workshops, and paint shopsderive the greatest benefit. The dryers robust construction and capability to operate under continuous loads make it ideal for demanding industrial environments.
