The WTA COMPACT+ is a split-system air conditioner distinguished primarily by its compact dimensions, which set it apart from other units in this segment. It is made from high‑quality glossy plastic.

Designed for installation in very small spaces—such as the lintel above a window—where limited height prevents mounting other units. For enhanced comfort, the air conditioner features four‑way electronically controlled louvers operated from the wireless remote, as well as a Wi‑Fi module that lets you control the unit from anywhere via a smartphone or tablet.

It can be fitted with one of six additional filters (PM2.5 filter, activated carbon filter, silver‑ion filter, vitamin C filter, photocatalytic filter, 3F filter) to further improve comfort and indoor air quality. The WTA COMPACT+ also operates at low outdoor temperatures—down to −16°C in cooling mode and −21°C in heating mode—making it an attractive option for supplemental room heating.
