2 General Contents DC Single fan row version DCD Double fan row version DCV V version Certifications and reliability The lfa Laval quality system is in accordance with ISO 01. ll products are manufactured to CE rules. For different fin materials, the following relationship shall be applied: Fins material l l painted Cu Factor F5 1 0,97 1,03 Nominal Capacity = Nominal capacity (2) x Fin Material Factor Nominal conditions The nominal capacities indicated in the catalogue refer to standard EN 1048 (Eth.Glycol 34%, T air =25 C, T IN = 40 C, T OUT = 35 C. For water, instead of Eth. Glycol 34%, the capacity and pressure drop at the standard conditions shall be calculated as follows: Noise level The noise pressure level shown in the table, is the weighted average of the values measured at 10 m, on the parallelepiped surface with reflecting plain. ny background noise and the acoustical conditions of the site installation, can usually influence +/- 3 d(). Nominal Capacity (water) = Nominal capacity (E.G. 34%) / 0.95 Pressure Drop (water) = Pressure Drop (E.G. 34%) / m 10 m 10 m 2 lfagreen - Dry Coolers

4 Dry Coolers DC pplication: refrigeration, process industry, air conditioning Range capacity kw Heat exchanger Innovative heat exchanger gives excellent heat transfer with minimized fluid volume, thanks to the new fin corrugation, developed by lfa Laval, combined with smooth tubes. Heat exchanger manufactured from aluminum fins and copper tubes with nominal diameter 3/8, for series with 500 mm fan diameter, and nominal diameter 1/2" for series with 630, 800 and 910 mm fan diameter. The fin spacing is 2.1 mm. Fan motors High efficiency fans with low power consumption are used. Four different fan diameters available: 500, 630, 800 and 910 mm with three-phase motors 400V-50Hz. The motors are with external rotor, made in accordance with VDE 0530/ Protection class IP 54 according to DIN Integrated thermal protection by thermo contacts provides reliable protection against thermal overload. New bell mouths optimize the performance of the fan motors and minimize the noise level. 4 lfagreen - Dry Coolers

Heat exchanger manufactured of aluminum fins and copper tubes with nominal diameter 1/2". The fin spacing is 2.1 mm. Double connections provide opportunity for two completely independent heat exchangers. Fan motors High efficiency fans with low power consumption are used. Two different fan diameter available: 800 and 910 mm with three-phase motors 400V-50Hz. The motors are with external rotor, made in accordance with VDE 0530/ Protection class IP 54 according to DIN Integrated thermal protection by thermo contacts provides reliable protection against thermal overload. New bell mouths optimize the performance of the fan motors and minimize the noise level. 14 lfagreen - Dry Coolers

20 Dry Coolers DCV pplication: refrigeration, process industry, air conditioning Range capacity kw Heat exchanger Optimized V type design provides large capacity with compact size. Innovative heat exchanger design gives excellent heat transfer with minimized fluid volume, thanks new fins corrugation, developed by lfa Laval, combined with smooth tubes. Heat exchanger manufactured from aluminum fins and copper tubes with nominal diameter 1/2". The fin spacing is 2.1 mm. Double connections provides opportunity for two completely independent heat exchangers. Fan motors High efficiency fans with low power consumption are used. Fan motor diameter 910 mm with three-phase motors 400V-50Hz. The motors are with external rotor, made in accordance with VDE 0530/ Protection class IP 54 according to DIN Integrated thermal protection by thermo contacts provides reliable protection against thermal overload. New bell mouths optimize the performance of the fan motors and minimize the noise level, besides thanks specific V design this series minimizes the fan motor power consumption. 20 lfagreen - Dry Coolers

21 56 standard models Double heat exchanger and double fan row Frame and Casework Casework made with galvanized steel sheets pre-painted with epoxy finish, RL 02, while supports and frame made with thicker galvanized steel bars provide high rigidity also for heavy applications. New system protects perfectly the heat exchanger tubes during transportation and operation against vibrations and thermal expansion. Simplest heat exchangers maintenance thanks full accessibility of the unit with fan motor bell mouths easily removable.
