LPHW
unit heater HC15-3S
Sleek and compact
The HC15-3S unit heater is our answer to customer demand for a compact device that, despite its small size, delivers high heating capacity. The unit therefore features several key improvements worth highlighting.
Innovation
Compact LPHW unit heater
The HC15-3S unit heater is our proposal for a compact device, well suited for use in smaller commercial spaces, but above all in residential premises such as garages or small workshops.
Low power consumption
and quiet operation too!
Thanks to a fan with a 300 mm impeller diameter, the power consumption is only 80 W.
Complete
equipment
- 3-stage speed controller with thermostat HC3S
- HC fan speed controller
- Manual thermostat — switches the unit heater on once the temperature set on the thermostat is reached
- MS maintenance switch — for quickly disconnecting the unit heater from the power supply when required
- Programmable controller HMI BMS
- Valves with actuators — for automatic regulation of the heating/cooling medium flow
- Thyristor fan speed controller — controls the unit heater’s fan speed through stepless voltage adjustment
Integrated
fan
This design minimises air intake from any direction other than perpendicular to the fan’s axis of rotation. It reduces pressure losses and ensures greater airflow through the unit heater. The result is higher capacity and efficiency.
In a workshop
If you have a small workshop you want to heat, the HC15-3S unit heater is the ideal choice. Its small dimensions and a heating capacity dedicated to compact spaces will keep your bills low, while the thermal comfort on cold winter days will turn work into a pleasure.
In a service shop
The HC15-3S model works great in service workshops such as car mechanics’ bays which, due to the small footprint of each station, do not require high-power unit heaters. Our compact unit heater is the perfect match for such conditions.
In a garage
If you want your garage to enjoy efficient heating, install the HC15-3S unit heater — its small dimensions let it fit any garage size. You can opt for a wall-mounted unit heater or one with a 360° diffuser mounted on the ceiling.
In a shop
The HC15-3S unit heater with a 360° attachment performs excellently in low-ceiling areas of small shops, where the distance from shelving to the ceiling determines the choice of an appropriate unit heater.
