Product Description

The Sonniger CR unit heaters are ideal for commercial and industrial applications. CR units are ultra lightweight and perfect for use with hot water generated from biomass boilers, gas boilers, or oil fired boilers.

The product’s extremely low weight comes from its unique design. Manufactured from expanded polypropylene it weighs up to 5 times less than a steel encased unit heater, making the unit very easy to install, as well as more environmentally friendly.
