  • Heat Exchanger provides a 5 PSI or less pressure drop across the whole dryer, even with the standard inlet filter. Specially designed for the compressor dryer industry.

Drying Systems - 301 Series

Today's ultra competitive business climate makes every dollar crucial in order to stay competitive. The Ultra Air 301 Series Thermal Mass Cycling Dryer offers energy savings that benefits that all-important bottom line. As its name implies, it cycles the refrigerant compressor on and off only in times of need. With standard, non-cycling refrigerated dryers the compressor remains on whether there is a high or low load.

Features:
  • Standard suction and discharge gauges on all units for easy detection of pressures. Standard electronic control panel for all models.
  • The compact, high efficiency counter-flowing evaporator minimizes the compressor size allowing for maximum energy savings.
  • Fan has sealed bearings, keeping it maintenance free for many years to come.
  • The glycol tank uses welded fittings, assuring zero leakage.
  • Standard liquid line filter dryer assures a clean, dry refrigerant system.
  • Powder coat paint finish.
  • Circulation pump - the wet rotor design allows it to be maintenance-free and minimize the energy consumed.
  • Zero Loss Drain - Does not allow expensive compressed air to pass
  • Heat Exchanger
  • Standard Delta Series™ 1 micron inlet filter removes oil and particulate, keeping the heat exchanger efficient for many, many years.

Drying Systems - UA Series

UA Series refrigerated air dryers use refrigerant to lower the temperature of compressed air, therefore lowering its dew point. As the air temperature and dew point drop, the moisture condenses into a liquid and is separated from your compressed air and drained away. The end result is cool, clean, dry compressed air ready to work for you and not damage your pneumatic equipment.

Drying Systems - UDR Series

The UDR Series High Temperature Refrigerated Air Dryer provides clean, dry, compressed air for auto body repair shops, auto service centers, dental offices, and small manufacturers without the need for an aftercooler or separator. The hot contaminated air first enters the standard coalescing filter capturing damaging dirt, water and compressor oils. The air then enters the dryer where it is cooled by R134a or R22 refrigerant (R134a and R22 are environmentally acceptable and contains no ozone depleting CFC's). As the air is cooled, the remaining water vapor is condensed into a liquid form. The liquid is then separated from the air stream and drained away providing the ideal air necessary to protect downstream components.

Features:
  • All copper constructed tube in tube heat exchanger to cool your compressed air stream.
  • 2 year warranty, 5 year heat exchanger warranty
  • Top quality refrigeration components
  • Electronic automatic condensation drain with push to test button on prefilter and separator.
  • 0.3 micron inlet coalescer oil removing filter.
  • Ambient air filter (standard).
  • R134a refrigerant for single phase units and R22 for 3 phase units.(Environmentally acceptable - no CFC's)
  • Refrigerant analyzer gauge.
  • No aftercooler or separator required.
  • Made in the USA

Drying Systems - LFT/LFE/LFA Series

Ultra Air Heatless Regenerative Dryers delivers a -40 F PDP, a dewpoint lower than that required by the Instrument Society of America. In colder climates, weather can negatively affect productivity by literally freezing and completely blocking outdoor air lines. Instrument air requires a quality of air that only a Regenerative type dryer can deliver. Therefore, whenever lower dewpoints are required for outdoor piping, instrument air, process air or gas drying, the Ultra Air Regenerative Dryings are the perfect solution.

Features:
  • Generous quantities of activated alumina desiccant
  • Centrally mounted pressure gauge and relief valves on each tower
  • ASME inspected and stamped and CRN registered pressure vessels (100 CFM and above)
  • Purge air mufflers to reduce exhaust noise
  • 115-160, NEMA 4x electrical
  • Repressurization of regenerating tower before it goes on drying cycle to prevent desiccant dusting.
  • -40º F pressure dewpoint (lower dewpoint available)
  • Control air filter
  • Low pressure drops (3PSID maximum)
  • Fail safe mode
  • Dryer sequence lights
  • Reliable and proven inlet air control valves and purge valves assure years of reliable shifting of towers and proper dryer operation (Lifetime Warranty) LF Series 25-620 CFM.
