Standard features include grooved tubing and louvered aluminum fins. The large face areas of the refrigerant coils provide superior efficiency for high SEER and HSPF performance. Coil circuiting has also been updated to make the most of all Carrier® heat pumps and air conditioners. Also units come with solid state fan controls, 1-in (25mm) thick insulation with R-value of 4.2, multi-speed motors, and fully-wettable coils. Units can accommodate factory and/or field-installed heaters from 3 to 30 kW.
It also should be noted that the unique cabinet design of these fan coils meet new stringent regulations for cabinet air leakage – a requirement of 2% cabinet leakage rate when tested at 1.0 inches of static pressure.
The FX4D fan coil is the Puron® refrigeration design loaded with popular features. It comes in a pre-painted (taupe metallic) galvanized steel casing and is shipped with a cleanable, permanent framed filter, and a factory-supplied power plug. These fan coils utilize the latest in electronic commutation motor (ECM) technology through the use of high efficiency, multi-tap ECM motors.
