Dryers

Installing a dryer is an essential step in treating compressed air and gases. By using economical and customized system solutions, Donaldson helps you not only to produce the required quantity of compressed air, but also provides your with dryers to reach the defined purity criteria according to the application. A range of heat-regenerated, heatless-regenerated, electrical and pneumatic dryers, oil vapor absorbers, breathing air systems as well as complete packages for the purification of compressed air can be chosen from.

Donaldson has designed system engineered solutions to achieve a real payback wherever compressed air is correctly filtered and dried. Whether is be high-efficiency dryers, dryers for large volume flows, water or air cooled, processor controlled, high pressure, complete plants or other requirements you may have, Donaldson supplies you with the right equipment. The range of refrigerant dryers we offer are easy and flexible in use, low in maintenance, highly efficient and environmentally friendly.

Ultrapac® 2000 Superplus / Standard

Ultrapac® 2000 heatless desiccant dryers (midi & mini) provide clean, dry air at pressure dew points of -40º C and -70º C. Their turnkey modular design includes a preinstalled coalescing pre-filter and particulate after-filter. 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. Information regarding the operating status, fault indications and maintenance intervals can be seen on a easy-to-read text display. A capacity control adjusts the adsorption cycles to the actual water inlet load therefore saving regeneration and at the same time reducing operating costs. An Economizer provides on-line information regarding the optimum exchange point for filter elements.

Ultrapac® HED / ALD / MSD

Ultrapac® Classic HED/ALD/MSD heatless desiccant compressed air dryers benefit from decades of design and fabrication experience by Ultrafilter. Our dryers are designed to consistently provide quality air with high energy efficiency in a flow range from 5 to 8750 m³/h at 7 bar g. Operation is fully automatic with a guaranteed outlet dew point at one of three pre-selected settings: HED, –20°C pdp; ALD, -40°C pdp; MSD, -70°C pdp. Each dryer in the 5-8750 m³/h flow range is enclosed in a protective cabinet with easy-to-remove panels. All Ultrapac® Classic dryers are supplied with preinstalled pre-filters and after-filters. The coalescing pre-filter 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.

Oilfreepac® 2000 & Oilfreepac® OFP

In addition to having all of the attributes of our Ultrapac® 2000 and Ultrapac® HED/ALD/MSD heatless dryers, Oilfreepac® 2000 (mini & midi) and Ultrapac® OFP dryers (sizes 0005-1000 to 1350-8750) include integral activated carbon filters for removing hydrocarbon and other vapours for critical applications for which the demand is oil-free and odour-free air.
