The unique mechanical design and control logic of Buran cycling refrigerated air dryers sets them apart from the competition in energy efficient operation. Even when operating at 100% capacity, Buran dryers with Ultrapulse technology consume less energy than traditional dryers utilizing hot gas bypass valves, and considerably less than thermal mass style cycling dryers. Power savings become even more apparent when operating at less than 100% capacity, as is often the case in real-world operation. All Buran cycling dryers are equipped with Ultramat zero-loss condensate drain valves.

The proprietary design of Boreas heat exchangers incorporates large flow channels for low pressure drop, which translates into low operating costs. A built-in cyclone separator with our Ultramat zero-loss drain valve allows for the removal of condensed water without wasting any compressed air. The space-saving design brings cooling air in the front and out the top, allowing the unit to be placed next to a wall with other equipment on either side. All Boreas dryers utilize environmentally friendly R134a refrigerant and are available in either air-cooled or water-cooled configurations.

Bora HPD dryers can accept compressed air at inlet pressures up to 650 psig in ambient temperatures up to 120¼ F. They utilize a two-stage stainless steel plate style heat exchanger for optimal heat transfer in the air-to-air and air-refrigerant circuits. Power consumption is reduced as less energy is required than conventional heat exchanger designs.

Ultrapac 2000 heatless desiccant dryers can provide clean, dry air at pressure dew points of -40¼ F and -100¼ F. Their turnkey modular design includes a preinstalled coalescing prefilter and particulate afterfilter. The desiccant is contained in easy-to-replace cartridges. The microprocessor controller alerts the operator of the optimal time to replace filter elements, keeping maintenance and operating costs at a minimum.

Ultrapac Classic ALD/MSD heatless desiccant compressed air dryers benefit from decades of design and fabrication experience by Donaldson Ultrafilter. Our dryers are designed to consistently provide quality air with high energy efficiency in a flow range from 3 to 5,000 scfm. Operation is fully automatic with a guaranteed outlet dew point at one of three pre-selected settings: ALD, -40¼ F pdp; MSD, -100¼ F pdp. Each dryer in the 3-600 scfm flow range is enclosed in a protective cabinet with easy-to-remove panels. All Ultrapac Classic dryers are supplied with preinstalled prefilters and afterfilters. The coalescing prefilter is equipped with the Ultramat zero-loss condensate drain. The compact design of Ultrapac dryers takes up a minimum of floor space, having one of the smallest footprints in the industry.

Ultratrockner HRE and patented HRS-L heated blower purge desiccant dryers consume less energy than heatless dryers by utilizing an external heater and ambient air for regeneration. The HRS-L zero purge air dryer saves additional energy by utilizing our patented process for vessel cooling in lieu of compressed air.

VarioDry membrane dryers are ideally suited for point-of-use applications that require compressed air at a higher purity level than that provided by the plant air system. When operating at full capacity, VarioDry membrane dryers reduce, or suppress, the dew point of inlet air by 36¼F. Dew point suppression will go up as flow is reduced. Our membrane dryers have no moving parts, do not require electrical power and are constructed with materials highly resistant to corrosion.
