The Buran Refrigeration Compressed Air Dryers are suitable for volume flows up to 1,650 m³/h. They are available in 4 sizes. With this sizes I to III represent a compact plug & play solution with integrated pre- and post-filters in a robust metal housing. Filters and condensate drains are more accessible considerably facilitating installation, maintenance and replacement most noteworthy.

The proprietary design of Boreas heat exchangers incorporates large flow channels for low pressure drop, which consequently 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 above all.

Bora DHP dryers can accept compressed air at inlet pressures up to 50 bar in ambient temperatures up to 50 ºC. The maximum inlet temperature is 60 °C. They utilize a two-stage heat exchanger for optimal heat transfer in the air-to-air and in the air-refrigerant head exchanger as a result.

Ultrapac 2000 heatless desiccant dryers (midi & mini) provide clean and dry air at pressure dew points of -40 ºC and -70 ºC. Their turnkey modular design includes a preinstalled coalescing pre-filter and particulate after-filter. The microprocessor controller alerts the operator of the optimal time to replace filter elements, therefore keeping maintenance and operating costs at a minimum. A capacity control adjusts the absorption cycles to the actual water inlet load therefore saving regeneration and at the same time reducing operating costs as a result. An Economizer provides on-line information regarding the optimum exchange point for filter elements.

Furthermore Ultrapac Classic HED/ALD/MSD heatless desiccant compressed air dryers benefit from decades of design and fabrication experience by Donaldson. Our dryers are designed to consistently provide quality air with high energy efficiency in a flow range from 5 to 8.750 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. Even more the compact design of Ultrapac dryers takes up a minimum of floor space.

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 1.350-8.750) 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.

A two-phase respectively three-phase filter stage provides the purification solution. The unit includes a microprocessor-controlled differential gauge and Economizer for optimum filter exchange indication. While the standard units include a sub-micro and activated carbon filter. With a flow rate of 60 m³/h, four persons can be provided with breathing air.

In addition the three heat regenerated absorption dryer ranges provide for a multitude of individual customer solutions. Analogue measuring and control units provide maximum operational safety at optimal energy consumption. A wide variety of standard options for e.g. the additional energy saving control Ultraconomy rounds off the offering. The standard rage for dew points up to –40 °C covers units from 375 m³/h to 13.600 m³/h. Larger capacities are available on request.

Finally the HRS absorption dryer range uses the absorbed moisture of heat caused by the compression process for desorption. The units therefore operate oil free, two-stage compressor without additional energy requirements. The total drying and regeneration cycle takes place under operating pressure. Heat exchange pressure of the desiccant and all other components therefore does not occur. This guarantees a long service life of components.
