5 General Specifications of STATIC Chilled Water Fan Coil Units Structure: Made from 0.8 mm thick (22gauge) galvanized (G90) steel sheet. All parts in direct contact with the treated air are insulated thermally and acoustically with 6 mm thick closed c ell foam insulation. The insulation is UL listed Drain pan: Made from 0.8 mm thick galvanized (G90) steel sheet, polyester powder coated for corrosion resistance as standard. Stainless steel drain pan can be provided as an option. Drain connection is ¾ steel pipe without thread for all units. Drain pipe can be left or right side of the unit looking at the air outlet. Drain pan is extended outside the cabinet and is insulated with 6mm closed cell foam insulation Heat Exchanger: Made from 3/8 " plain copper tubes, mechanically expanded into saw type aluminium fins. Heat Exchangers are specifically designed for district cooling chilled water application by properly differentiating the coil circuits. Heat Exchangers are leak tested at 450 psi and maximum working pressure should be 250psi. Heat Exchangers are 4Rows provided with manual air vent. Headers are made from copper with brass MPT for water connection. Water connections can be left (left coil) or right (right coil) of the unit looking at the air outlet. As standard the drain and water connections are on the same side, unless otherwise specified. Fan: Fans are double inlet double width (DIDW), centrifugal type, forward curved, statically and dynamically balanced, horizontally oriented with glavanized steel impeller in galvanized steel casing. Fan Motor: Motors are of PSC type, with built-in thermal overload cut out and permanently sealed and lubricated ball bearings. Motors are provided with 5-speeds. Factory pre-selected and pre-wired to the junction are 3 speeds for high, medium and low. The selection must not be changed without consulting the factory and considering the actual operating ESP. The insulation class B and IP 23 Air Filter: The filters are factory installed aluminum type, 12.5mm thick, permanent and washable. The filter media is UL Listed The Units are constructed with special design for low height application above the false ceiling and the flanged air outlet is properly sized to reduce noise. Units are manufactured with Ceiling anchoring slots for easy fixing and leveling of the unit. The bottom panel at the fan deck side can be removed for easy access and maintenance of motor and blowers. Performance data are based on actual working conditions considering the extra pressure drop from the wet coil and aluminium filter. The Maximum face velocity (at 0 ESP and high fan speed) is below 2 m/s for low noise and low pressure drop purposes. 5
