Air cooled condensers AlfaBlue BCM / BCD Application The Alfa Laval Condenser can be used in refrigeration and air conditioning equipment. Heat exchanger Innovative heat exchanger gives excellent heat transfer with minimized refrigerant charge, thanks to the new fi ns corrugation, developed by Alfa Laval, combined with advance cross fi n tubes. In the standard execution, heat exchanger manufactured from copper tubes and aluminium fi ns with spacing is 2.1 mm. In the BCD, double connection provides opportunity for two completely independent heat exchangers. Each heat exchanger undergoes a pressure and leaking test with dry air at 34 bar (Design pressure is 31 bar), and fi nally supplied with a nitrogen pre-charge. AlfaBlue, BCM and BCD Fan Motor On the BCM, four different fan diameters are available: 630, 800, 910, 1000 mm; on the BCD, 800, 910, 1000 mm with three-phase motor 400V-50Hz. The motors are with external rotor, protection class IP54 according to DIN 40050. Integrated thermal protection by thermo contacts provides reliable protection against thermal overload. These Axial Condensers BCM and BCD are available in fi ve noise levels fan motor, (S) standard, (L) low, (Q) quiet, (R) residential and the new (T) high performance fan Frame and Casework Casework made with galvanized steel sheets painted (corrosion resistance class C4). New design frame provides high rigidity also for heavy applications. New system protects perfectly the heat exchanger tubes during transportation and operation against vibration and thermal expansion. Support manufactured in galvanized steel, with optimised length to permit uniform air suction in the coil.
