AC or EC?

AC or EC? At SONNIGER, the choice is yours.

HEATER CONDENS units are available with two motor options, designed to meet different project requirements and budget constraints.

The AC version is a robust, field-tested design featuring 3-speed control. Its competitive pricing and straightforward installation make it an excellent choice for standard applications.

The EC version takes performance to the next level. The electronically commutated motor provides stepless speed control, whisper-quiet operation, and up to 40% lower running costs. The brushless design extends the unit's lifespan, while direct BMS connectivity allows for seamless integration into building automation systems.

Both versions are fully compatible with SONNIGER controllers—ranging from the essential Comfort model to the advanced Intelligent WiFi and Intelligent PRO.
