The J-II single-phase variable refrigerant flow (VRF) serves ambient heating and cooling applications in a 3- to 5-ton range and can be used for large residential and small commercial installations.

Fujitsu has introduced a Wi-Fi solution for its Halcyon line that allows installers to operate a Fujitsu Halcyon mini-split system from anywhere with a smartphone, laptop, or tablet. 

The 9,000- (9RLS3), 12,000- (12RLS3), and 15,000- (15RLS3) Btu model wall-mounted ductless split systems provide up to 33 SEER and 14.2 HSPF. 

Two new Halcyon lines of high-efficiency, floor-mounted mini-split heat pump systems feature ambient heating temperatures as low as minus 15°F (RLFFH line) or minus 5° (RLFF line). 

Bill Rouner is a physicist who spent much of his career in the aerospace industry. So, it only made sense when he did some research.

The Halcyon light commercial multi-zone heat pump line has expanded and now offers 56,259 combinations to achieve greater mix-and-match flexibility. 

Wall-mounted, the RLS2H ductless extra low-ambient temperature heat pumps are available in 9,000- 12,000-, and 15,000-Btu configurations.
