Main Features
General
The new MCW-D FCUs are specically designed to satisfy high cooling capacity application requirement. They
represent one of the most cost effective solutions to provide a comfortable environment for both commercial and
residential applications. Their quiet operation, compact dimensions and particularly low height, make units ideal
for ceiling concealed installation even in buildings with narrow ceiling spaces. Units are standard supplied with
soundproofed suction plenum and air lter. Centrifugal fans, with forward-curved blades, are statically and dynamically
balanced and driven by single-phase motors with three speeds.They feature elegant design, advanced structure,
high efciency, low noise, convenient installation and low maintenance. They are widely used in houses, shopping
malls, hospitals and ofce etc.
Higher Cooling Capacity in High Delta T Application
These units are particularly suitable for high External Static Pressure and high Delta T(chilled water temperature
difference) applications. They can delivery more cooling capacity in high Delta T conditions with the specially designed
fans & motors, coils and excellent combination of them.
Low Chilled Water Pressure Drop
In order to meet even the most demanding customer requirements, the new FCUs adopt the most reasonable
and optimization water circuit design and utilize the national level thermal test room to guarantee both the perfect
performance and a low chilled water pressure drop.
Extra High Air Flow Volume at High ESP
These units can supply more air ow at high ESP. 10 models of MCW-D cover an air ow range from 340 to 2380CMH
at medium speed with ESP of 75Pa in wet coil condition.
Air Filter
All units can provide up to one-inch thick washable lters. Filters are held by a removable metal strip and can be
easily pulled out from the bottom for cleaning or replacement.
High Efciency Heat Exchanger
A boundary layer lm of air adhering to the n surface will insulate the n surface and severely reduces the heat
exchange efciency. McQuay slit n design eliminates this boundary layer of air and creates continuous turbulence
for best heat exchange efciency.
Flexibility
Units are available with left or right hand water connections, which can be easily switched in the eld by changing the
positions of the fan-motor assembly and the supply air ange assembly if required.
Compact Design
The low height design makes this fan coil unit series ideally suited for the tight ceiling concealed installation
Low Noise Design
Enlarged fan wheels design allows lower fan RPM selection for the same external static pressure and airow
requirement. Thereby noise level is signicantly reduced.

Unit Description
Factory-assembled, horizontal, blow-thru type, galvanized casing, ceiling ducted fan coil unit is complete with water
coil, fans, motors, drain pan, lters 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 Specications
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 ns 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 re reluctance.
6. Filter
Filter is with washable type double-layer nylon media in 25mm thickness aluminum frame.
