Fujitsu’s New Single-zone Halcyon Heat Pumps

What is it?
Fujitsu General America, Inc. has expanded its Halcyon single-zone mini-split heat pump lineup with new slim duct and compact cassette indoor unit models. The new light commercial systems are available in 9,000, 12,000, and 18,000 BTU capacities.

Why is it needed and important?
The new light commercial systems have coils made of high corrosion resistance copper (HCRC) to provide great durability. An enhanced controls platform provides multiple options to optimize comfort and energy savings. Installation, service, and the end-user interface are easier than ever. 

What are the key aspects?
The systems feature a custom auto function, external input/output connectivity, two-wire remote compatibility, and dual UART communication ports (WIFI, BACnet, External I/O, etc.). Simultaneous connection of wired remote controller, WIFI adapter, and external input/output board is simple. Service monitoring is conducted through a new touch panel controller. Maximum line set lengths have been extended; up to 98 feet total piping length for 18,000 BTU systems.

The new, compact units offer sound levels as low as 24 dBa. Slim-duct systems feature a modular design that’s field configurable for vertical or horizontal installation with bottom or rear return.

Optional accessories include a wired remote controller, thermostat converter, wireless LAN interface, external connect kit, remote sensor, Modbus, BACnet, KNX converter, and an external switch controller. Available for use with the slim duct is an IR receiver kit and louver grille kit. An IR remote kit, cassette grille, and fresh air intake are available for the compact cassette.

Where can you get it? 
The new systems are available to order and ship now. For more information, visit
