Split-system heat pumps

February 25, 2010

Fujitsu General America, Inc., now offers three new ductless wall mount split system heat pumps with longer refrigerant pipe lengths and high energy efficiencies. Each of the three systems offers an extended line set capability, providing a line set maximum of 165 lineal feet.

The new 18RLXS is an 18,000 BTU, 19 SEER, 10 HSPF heat pump that qualifies for Tier 2 Energy Star ratings, making it eligible for up to a $1,500 Federal tax credit.

Fujitsu’s 24RLXS, a 24,000 BTU heat pump with an 18.0 SEER, 10.0 HSPF rating qualifies for Tier 2 Energy Star ratings, also making it eligible for up to a $1,500 Federal tax credit. The 24RLXS operates optimally at temperatures of 0°F for cooling and 5°F for heating purposes.

Also, the company’s 30RLX heat pump provides 30,000 BTUs of heating and cooling with ratings of 16 SEER and 9.5 HSPF. The 30 RLX also provides low ambient cooling operation down to 0°F, making it ideal for computer room cooling applications.

These units are available with these capabilities right off the shelf with no modifications needed for low ambient operation. There is no need to add a crank case heater, fan cycle control or larger suction accumulator to protect the compressor; these are already built-in.

 Fujitsu’s Halcyon line is designed to offer ultra-high efficiency, quiet, reliable operation, and sleek design. The Halcyon lineup now includes 22 single zone systems with capacity ranges of 9,000 to 42,000 BTUs. Mix-and-match evaporators of the multi-zone systems allow contractors and owners to create the perfect climate control for any size space.

Standard features include wireless remote control, sleep timer, 24-hour timer, dry mode, auto louver, auto mode, quiet mode, auto restart/reset, auto changeover, and efficient operation with low or high ambient temperatures.
