Boreas Refrigeration Compressed Air Dryers with Variopulse
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 utilise environmentally friendly R-134a refrigerant and are available in either air- cooled or water-cooled configurations. Volume flows of 1.800 to 28.500 m³/h are covered by the Boreas series.

Bora HPD High Inlet Pressure Dryers
Bora HPD dryers can accept compressed air at inlet pressures up to 45 bar in ambient temperatures up to 50ºC. The maximum inlet temperature is 60°C. 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. Volume flows of 40 to 6.000 m³/h are covered by the Bora series.

Ultrapac® 2000 Superplus / Standard Heatless Regenerated Adsorption Dryers
Ultrapac® 2000 heatless desiccant dryers (midi & mini) provide clean and 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 an 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 Heatless Adsorption Dryers
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 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 5-1000 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.

Membrane Compressed Air Dryers VarioDry / FRL
For maintenance units it also applies that the requirements for compressed air determine the components for the processing. As opposed to central processing where the compressed air is kept on the high quality level of the demanding area of application, the processing directly at the consumer only requires the components needed on site. Decentralised processing saves energy and costs especially when only a part of the generated compressed air needs to fulfil high requirements.
The compact FRL units can processes volume flows of 2 to 150 m³/h. |

Ultrapure ALG20 Breathing-Air Systems
The portable ALG20 breathing air unit is used when the breathing air is contaminated by the working process e.g. during sandblasting. 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. 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.

Ultrasorp AKC Activated Carbon Adsorption Dryers
The AKC is an activated carbon absorber for the removal of oil vapours and hydrocarbons. It has a residual oil indicator with an accuracy of smaller than 0.01 ppm. The AKC models cover volume flows of 5 to 8.750 m³/h and have been built and tested for temperatures up to 50°C. The installation of a sub-micro filter on the inlet side of the AKC prevents oil carry-over to the activated carbon.

Ultradryer HRC Heat Regenerated Adsorption Dryers
The HRC adsorption 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. Units with the sizes 600 to 60.000 m³/h have already been built. |
