Features
Extra Low Noise Design
Enlarged fan wheels design allows lower fan RPM selection for the same external static pressure and airflow
requirement. Thereby, noise level is significantly reduced.
Flexibility
Water connection side can be changed easily in the field by changing positions of fan-motor assembly or
the supply air flange assembly. Fan-motor assembly is not cased allowing back return or bottom return
installations.
High Efficiency Heat Exchanger
A boundary layer film of air adhering to the fin surface will insulate the fin surface and severally reduces the
heat exchange efficiency. Mcquay slit fin design eliminates this boundary layer of air and creates continuous
for best heat exchange efficiency.
Variable External Static Pressure
Four types of external static pressure are available for every unit:0PA, 30Pa,,60Pa,80Pa.
Compact Design
This series of fan coil units are designed to suit most ceiling concealed installations. Unit height is only
51mm across the entire model range. The feature also maximizes provisions for drain fall requirements.
New design realizes all the filters removal both from the side and bottom(Option).
Auxiliary Electric Heater (Only For Type C)
The heating source of Mcquay fan coil unit is PTC (Positive Temperature Coefficient) heater.
1. Safety
A fuse (135°C,10A) is connected in each PTC main wiring circuit. A thermostat (50°C,10A) is connected in
the control wiring circuit. If the fan of the units is not running, the thermostat or fuse will cut off the power
of the unit. In additional, the surface of the PTC heater is without electric power. So the fan coil unit is safe
enough.
2. Save Energy
Quick heating spread, strong heating capacity, steady performance and save energy are characters of
PTC heater.
3. Easy To Install And Maintain
Needn’t remove the air duct when maintain the electric components of the units. Please refer to the
corresponding sections for installation and maintenance.
