Product Details
CONSTRUCTION Structure is composed of pre-painted heavy gauge GI sheet (conforming to ASTM 653A) and high strength plastic with excellent mechanical characteristics. The outer surface is pre- painted to RAL 9010 at 50-70 micron. The complete unit is insulated using polyethylene foam insulation bonded the inner surface. Such an arrangment permits high strength, low thermal transfer, high noise absorption and low flammability. FAN MOTOR ASSEMBL Y Units are equipped with double inlet, double width, forward curved centrifugal fans. All fans are made from hot dip galvanized steel to prolong longetivity. Fans are statically and dynamically balanced to prevent vibration. The fan housing shall be of galvanized steel. Selection of fans are done to meet the specified air flow at low outlet velocities and opti- mum motor safety factor. All units are provided with a factory installed terminal box with the motor wired to the box. The single phase three speed induction motors comply with low voltage IEC standards. All motors are permanent split capacitor type with sleeve bearings. Transmission is effected via keyed shafts. Motors are mounted on rigid bases to offer rigidity, isolate vibrations and pre- vent movement. All motors come with an auto reset overload protector. Motor shafts are pre-treated to protect against corrosion. COILS In order to offer true unit selection, coils are available with three different cooling medium - water, refrigerant and glycol. Coils are fabricated of 3/8” OD copper tubes. Fins are made of aluminum and are pressure bonded to the tubes through mechanical expansion. Fins are selected to provide maximum contact area while minimizing air pressure drop. Coils are encased in galvanized steel. Head- ers are made of seamless copper brazed to the tubes. All coils are pressure tested at a minimum pressure of 350 PSI. All coils are rated in accor- dance to ARI 410. All coils are selected at a face velocity below 2.5m/s (500 fpm). All coils are factory tested for leaks before installation and dispatch. The drain pan is of painted GI construction with polyethylene insulation and drain pipe. FIL TER SECTION Filter is a plastic honey comb washable type with rigid frame. It can be easily withdrawn from the bottom.
