Two Halcyon ductless split system wall-mount models are designed with longer refrigerant pipe lengths (165 lineal feet) and lower ambient operation for heating or cooling. They operate at outdoor temperatures as low as 0°F. The low ambient operation is especially useful for ambient cooling of computer rooms during the winter months, says the company. These units are equipped with IAQ plasma filtration. The 24,000-Btu 24RLQ wall-mounted heat pump is replaced by the 24RLXQ while the 30,000-Btu (30CLX) cooling-only system is being supplemented with the 30RLXQ. Features include a crank case heater, fan cycle control, or larger suction accumulator to protect the compressor.
