Dry cooler BDP AlfaBlue - Power Dry Cooler AlfaBlue Power Dry Cooler Application The AlfaBlue Power Dry Cooler is designed for Industrial Cooling (water or other fluids cooling) in many applications: • Diesel/Gas engines in Power plants • Gas turbine cooling system • Direct process cooling and Indirect cooling (using an intermediate Plate Heat Exchanger) of process liquid (hydraulic oil, air compressor, etc) Heat exchanger The innovative heat exchanger gives excellent heat transfer thanks to the new fins corrugation, developed by Alfa Laval, combined with smooth tubes, not sensitive to dirt and with a long stability of the performance values. In the standard execution, the heat exchanger finned coil block is manufactured from copper tubes and aluminum fins with spacing is 2.5mm. A new floating system, used in all AL air products, protects perfectly the heat exchanger tubes during transportation and operation against vibration and thermal expansion. The design is modular to fit the required cooling capacity. The combined model (two coils in sandwich), designed for Power Industry, permits to cool two different circuits (i.e. LT and HT engine circuit) in a unique, compact liquid cooler. Each heat exchanger undergoes a pressure and leaking test with dry air at 10bar (Design pressure is 9bar). Fan Motor The fan propellers are direct driven to reduce the maintenance and the fan blade available materials are: aluminum, galvanized steel or fiber glass to match every ambient conditions. The motors are squirrel-cage type, particularly designed for: outside installation, vertical position shaft, protection class IP 55, protection/working class is F/B or H/F. Each motor is completely wired by the factory to an isolating safety switch on-off, fixed with a top protection cover. Frame and Casework Casework is made with galvanized steel sheets to guarantee higher rigidity in heavy industrial application. All the casing parts are double painted in high quality level or, in alternative, top horizontal casing parts could be in hot dip galvanized steel. The AlfaBlue frame design permits: the installation on a steel frame (a platform) avoiding the warm air recirculation risk, installation time and cost saving and the Alfa Laval handrails kit fast installation.
