Main Features
General
The new MCW-DA FCUs are specically 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 efciency, low noise, convenient installation and low maintenance. They are widely used in houses, shopping
malls, hospitals and ofce 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
optimized water circuit design and utilize the National accredited 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. 11 models of MCW-DA cover an air ow range from 200 to 1600
CFM at medium speed with ESP of 75Pa.
High Efciency and Energy Saving
A boundary layer lm of air adhering to the n surface will insulate the n surface and severely reduces the heat
exchange efciency. McQuay slit designed and HYDROPHILIC BLUE FIN eliminates this boundary layer of air and
creates continuous turbulence for best heat exchange efciency.
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 speed selection for the same external static pressure and airow
requirement. Thereby noise level is signicantly reduced.
Powerful Selection Software
Powerful select software makes various conditions selection precise and cost saving.

General Data
NOTES:
1) ALL SPECIFICATIONS ARE SUBJECTED TO CHANGE BY THE MANUFACTURER WITHOUT PRIOR NOTICE.
2) THE PERFORMANCE DATA ARE BASED ON THE FOLLOWING CONDITIONS:
A) COOLING: 24°C DB/18°C WB INDOOR AND WATER INLET 5.5°C OUTLET 14.5°C.
B) MEDIUM SPEED,75PA ESP.
C) 220V/1PH/50HZ.
3) ALL THE DIMENSIONS ARE FOR THE UNITS WITH STANDARD DRAIN PAN. TO GET DIMENSIONS FOR UNITS
WITH EXTENDED DRAIN PAN, PLEASE INCREASE THE ABOVE LENGTH VALUES ACCORDINGLY.
4) WHEN THE WATER CONNECT DIRECTION IS CHANGED IN FIELD,THE CAPACITY SHOULD BE REDUCED BY 6%.
