Dry Cooler VDD / VDD6 Alfa V 800, 910 & 1000 mm Applications Refrigeration and air conditioning applications: – water / glycol cooling – free cooling Industrial applications: – cooling of water or other different liquids – food, power, process and general industry. Heat exchanger Optimized “V type” design provides large capacity with compact size. Innovative heat exchanger design gives excellent heat transfer with minimized refrigerant charge, thanks to the new fins corrugation, developed by Alfa Laval, combined with two different tube sizes 1/2” (VDD series) and 5/8” (VDD6 series). In the standard execution, heat exchanger manufactured from copper tubes and aluminium fins with spacing 2.1 mm. Double connection provides opportunity for two completely independent heat exchangers. Each heat exchanger undergoes a pressure and leaking test with dry air at 11 bar. Fan motor Three different fan diameters available: 800, 910 and 1000 mm with three-phase motor 400V-50Hz. The motors are with external rotor, made in accordance with VDE 0530/12.84, IP54. These Dry Coolers are available in five noise levels fan motor, (S) standard, (L) low, (Q) quiet, (R) residential and the new (T) high performance fan dry coolers VDD/VDD6 800 and 910 are available in 4 noises level fan motor, (S) standard, (L) low, (Q) quiet and (R) residential. Dry Coolers VDD/VDD6 1000 are available in 3 noises level fan motor, (L) low, (Q) quiet and (R) residential. New bell mouths optimize the performance of the fan motors and minimize the noise level. Each fan chamber is separated by internal baffle plates which enables optimal capacity control by separate running of the fans. Frame and casework Casework made with galvanized steel sheets painted (corrosion resistance class C4) with epoxy finish, RAL 9002. New design frame provides high rigidity also for heavy applications. New system perfectly protects the heat exchanger tubes during transportation and operation against vibration and thermal expansion. Support manufactured in galvanized steel.
