Focused Zone Comfort

The GX Series is engineered for spaces where HVAC systems need help or where duct installation is impractical. The inverter compressor modulates output precisely to match the load, reducing temperature swings, minimizing electrical surges at start-up, and extending compressor life. For property managers, that translates into predictable utility expenses and fewer maintenance calls.

Each louver position is individually adjustable, letting you direct air away from workstations or toward hard-to-reach corners. Pair that airflow control with the built-in dehumidification setting, and you can tackle both hot and humid weather without switching devices.
