Unit Description
Factory-assembled, horizontal, blow-thru type, galvanized casing, ceiling ducted fan coil unit is complete with water
coil, fans, motors, drain pan, filters and all required wiring, with full access to internal components.
Quality Assurance
Each coil is factory tested for leakage at 3.3MPa air pressure with coil submerged in water. Each unit and its moving
components (fans and motors) are factory computer-tested and recorded after unit is complete and before it is
packed.
Component Specifications
1. Casing
Construction is of 0.8mm thickness galvanized steel, lined on the inside with 5mm PE thermal and acoustical
insulation. Return air plenum is lined with 5mm PE foam and has a 20mm collar for return duct connection. Supply
duct connection also has a 20mm long collar. Removable bottom panel is provided for access to the fan/motor
assembly.
2. Coil
Standard unit is equipped with a 4-row coil for installation in a 2-pipe system. Coil has 3/8 inch seamless copper
tubes, slit type aluminum blue fins bonded to the tubes by mechanical expansion. Each coil has a manual air vent
and two Rc3/4 water pipe connections with a working pressure of 1.6MPa.
3. Fan
Direct-driven centrifugal fan wheel has forward-curved blades which are statically and dynamically balanced. The fan
housing and blades are constructed of high quality hot-galvanizing steel.
4.Motor
Fan motor is 3-speed, 220V-240V, single-phase, 50Hz, permanent split-capacitor type with ball type bearing and
build-in automatic reset thermal overload protection. The motor’s insulation is class B.
5. Drain pan
The drain pan plate body is constructed of cold-rolled steel by way of integral cupping. Both its sides are sprayed
with plastic coating. And its outer wall is lined with 6mm heat insulating PE foam and high quality adhesive by way
of integral adhering and pressing. It extends under the full length and width of the coils and is pitched for positive
drainage with features of high anti-corrosion, anti-condensation and high fire reluctance.
6. Filter
Filter is with washable type double-layer nylon media in 25mm thickness aluminum frame.
