AIR HANDLER TECHNOLOGY
AT ITS FINEST
The FX4D fan coils combine the proven technology of Carrier fan
coil units with Puron, the environmentally sound refrigerant.
These fan coils are loaded with popular features. Factory--installed,
refrigerant--specific thermostatic expansion valves (TXV) are
standard with these fan coil designs. The designs feature contoured
condensate pans with rugged, drain connections, ensuring that little
water is left in the unit at the end of the cooling duty cycle. The
lack of standing condensate and corrosion free pans improves IAQ
and product life, features homeowners appreciate.
Standard features include grooved copper 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. ArmorCoatt
provides a tin plating of the indoor coil’s copper hairpins. This
creates a barrier between the corrosion--causing elements and the
coil. These fan coils utilize the latest in electronic commutation
motor (ECM) technology through the use of high efficiency, X13,
blower motors.
