1 Guide Specifications General CR-A series ducted concealed chilled water fan coil units have an air flow range from 45 to 3060 cubic meters per hour with a capacity range from kw up to 9 kw. The CR-A series covers a wide range of external static pressure from 0 Pa up to 00 Pa. The units offer excellent features and benefits in terms of the following: compact size, low initial cost, super low noise operation, ease of installation and ease of maintenance making them ideal for or heating a wide range of applications including apartments, banks, hotels, shopping malls, show rooms, air ports, stores, museums, high rise buildings, schools, office buildings and many other applications. Casing CR-A casing provides excellent inherent strength, stability and air tightness. The casing is fabricated from heavy gauge hot dipped galvanized steel sheet metal (Electrostatic painted casing is available upon request). The casing is insulated with 5 mm thick closed cell insulation (other thickness are available upon request) forming a rigid enclosure with high acoustic attenuation, high thermal insulation and superior air tightness. Sufficient strengthening forms and folds are incorporated to give a robust vibration free assembly. All units are supplied with a collar for direct connection with the supply and return air duct. Coil/Drain pan Chilled water coils are constructed of 3/8 inch copper tubes, mechanically bonded to high efficiency corrugated aluminum fins. Standard coils are three rows deep with an option of two or four rows depending on the required specifications. All coils are factory tested at 30-atmosphere pressure according to the international standards and are sealed with a quality pass label and a traceable serial number before being installed in the units. Optional fin materials are available upon special request, including golden plated, vinyl-coated aluminum and copper. The coil matrix is held firmly within a heavy gauge galvanized framework. The coil assembly complete with brass distributors and a manual air vent is located above a full width condensate tray which covers both the entire coil face area and the coil headers, return bends, distributors and control valves. The condensate tray (drain pan) is constructed of corrosion resistant electrostatic painted galvanized steel sheet metal (other construction materials are available upon special request, including aluminum and stainless steel) and externally insulated by 5mm thick closed cell insulation (other thickness are available upon request). The drain pan is internally sloped for a smooth, clogging free drainage mechanism. The drain outlet is threaded and plugged with a plastic cap for simple on-site connection. Water connections are standardized on the right hand side of the coil when facing the airflow with male threaded header of ¾ inch.the coil can be supplied on either sides according to the customer requirements and can be turned on site for more flexibility. Fan/Motor Direct drive fans are centrifugal, forward curved with double-width wheels. The fan housing is constructed of heavy gauge galvanized steel. The fan wheel is constructed of high tensile aluminum or heavy gauge galvanized steel. The fan wheel and housing are designed to minimize air borne noise levels. All fan wheels are individually tested and precision balanced statically and dynamically and keyed to the shaft. Fan motors are single or double shaft, class B insulation (class F is available upon request), resilient-mounted, three or five speeds tapped wound with thermal overload protection and a permanent split type capacitor. Three speeds are pre-wired as standard. All motors have long life self lubricated bearings of the sleeve or ball bearing types. All wiring is made at 0V, single phase and 50HZ. Motors are suitable for 50Hz, single-phase with 0/40, operating voltages. 60Hz, single-phase motors are also available as an option with 08/0V operating voltages. Filter Two filter options are available for the CR-A series including washable synthetic and aluminum filters. The first option is filter cells with filter media composed of polyester A40. The filter frame is constructed of corrosion resistant galvanized steel sheets. The synthetic filter is flame resistant according to F-Din classification. The second option is regenerable filter cells with multi layer metallic media composed of aluminum. The filter frame is constructed of corrosion resistant galvanized steel sheets. The average gravimetric efficiency is 75% with EN 779 G classification. The aluminum filter is fireproof. Either options come with mm filter thickness as standard. (Other media thickness is available upon request) The filter section is designed to easily withdraw the filter panels for maintenance or renewal when required.
