1 Buran Refrigeration Compressed Air Dryers

2 Buran Refrigeration Compressed Air Dryers Trust Donaldson to deliver a complete range of compressed air purification solutions that improve air quality throughout your plant from compressor rooms to all points of use. With over 30 years of expertise in compressed air filtration and separation, Donaldson manufactures a complete line of refrigeration, adsorption and membrane compressed air dryers to help produce clean, dry air and comply with air purification requirements. The unique mechanical design and control logic of Buran refrigeration compressed air dryers provide peak energy efficiency. When operating at 100% capacity, Buran dryers with Ultrapulse technology are more efficient than traditional dryers, and cost much less than thermal mass style dryers. Buran dryers also offer power savings when operating at less than 100% capacity, which is often the case in real-world operation. All standard Buran refrigeration dryers are equipped with a load controlled solenoid valve and cover a volume flow range of 50 to m 3 /h. Intelligent Design Components of Buran refrigeration dryers have been designed, specified and integrated to incorporate advancements in compressor life, heat exchanger design, computer control and real-time operating conditions. Intelligent Control Ultrapulse technology not only controls the dryer s operation in reaction to load changes, but also continuously tracks and anticipates load trends, adjusting the refrigeration circuit accordingly. This advanced control logic optimizes performance by avoiding dew point spikes commonly associated with cycling dryers. Intelligent Operation Buran dryers with Ultrapulse technology provide three function modes: Standard, Summer and Flex providing high flexibility, low energy consumption and consistent compressed air quality. The Buran Advantage Generously sized air-to-air and refrigerant-to-air TRISAB heat exchanger provides for the highest heat transfer efficiency possible (from SD 0080 AP onwards) Integral condensate separation with load control eliminates the need for external condensate removal Low pressure drop saves energy costs Corrosion resistant all aluminium construction (from SD 0080 AP onwards) High thermal mass for wide range thermal efficiency increases power efficiency while reducing compressor cycling Ozone friendly and environmentally safe R134a refrigerant Ultrapulse energy saving controller comes standard Multi-functional display allows for easy monitoring of real-time operations Dew point temperature display in C or F Load controlled energy consumption with no compromise on air quality Optional dry contact for alarm signal & analog signal 0-10V for dew point temperature enables centralized monitoring system Withstands the harshest external operating conditions (Max operating parameter, inlet temp. 60 C, ambient temp. 50 C for whole series) Compact cabinets for easy installation and mobility

3 Refrigerant Compressor Unlike lower quality refrigeration dryers, Buran dryers are designed with an operating cycle that activates the compressor based on actual load, eliminating the need for a hot gas bypass valve. Users benefit from reduced energy consumption and lower operating costs. TRISAB Heat Exchanger Buran dryers (models SD 0080 AP through SD 1650 AP) are built with Ultrafilter s TRISAB heat exchanger and take advantage of its aluminium mass for energy storage. The ability to store and use cooling energy adds to the power efficiency of Buran refrigeration dryers. TRISAB is a three-stage aluminium block heat exchanger with integral pre-cooling of the process air, final cooling to the required dew point and internal condensate collection. A microprocessor-based controller gives Buran dryers (models SD 0080 AP through SD 1650 AP) their energy efficient intelligence. The controller is programmed to measure and respond to critical operating parameters, and to track and anticipate demand. Ultrapulse operating logic avoids dew point spikes while operating at the most energy efficient cycle. Buran Ultrapulse Microprocessor Controller Monitors all critical input and output parameters Calculates actual conditions of dryer for continuous control Continuous indication of operating parameters on multifunction display Three modes of operation for highest flexibility and lowest power consumption The Multi Functional Display shows all relevant parameters: Current pressure dewpoint Operation mode Normal/Summer/Automatic Power consumption related to the whole life time Alarm signal Alarm history Maintenance intervals Operation status of the drain Operation hours Refrigerant compressor on/off Actual energy consumption
