HC15-3S Unit heater
Compact and elegant

Our customers have a handful of needs in regards to a compact device, which would have a great heating power, in contrary to it's small size. We provide an answer - the HC15-3S Unit heater. Our newest device introduces several key changes, which deserve a mention.

Built-up ventilator

This solution minimises air intake from a direction other than perpendicular to the fan rotation axis. This minimises pressure losses and ensures greater air flow through the heaters. This results in greater efficiency and effectiveness of the device.

In the lab

When you're in need of heating your little lab, the HC15-3S Unit heater is a perfect choice. Its compact design and power dedicated to small spaces will make your worries about bills go away, while the heat comfort during the winter afternoons will make working at home enjoyable.

In the workshop

The HC15-3S model works perfectly in work-oriented spaces such as car workshops, which due to their relatively smaller size, do not require as great of an intake power. Such conditions are perfectly met with our compact unit heater.

In the garage

If you want your garage to have an efficent heating, mount yourself an HC15-3S Unit heater, which is perfectly suited for garages of any size. You can decide whether you want to mount your unit heater on a wall, or have a unit heater with a 360 diffuser mounted under the ceiling.

In the shop

The HC15-3S Unit heater with a 360 diffuser is a wonderful solution to low rooms in small shops, whose height from the rack to the ceiling decides about the choice for a fitting unit heater.
