Product Description

The Sonniger Heater R unit heater (LPHW) is a groundbreaking solution for heating commercial and industrial buildings. It is uniquely designed and manufactured from expanded polypropylene which reduces the weight of a typical 70kW unit by up to 5 times that of a traditional steel encased unit heater. This results in ease of installation for the contractor, a lifetime casing guarantee for the customer and significant benefits to the environment.

Design & Installation

Download Manual

The fan’s motor is equipped with an internal temperature limit fuse protecting the engine from overheating.
The unit set does not include a feeding cable or a master switch.
The electrical installation and connection of the automatic control should be carried out in accordance with the electrical diagram by an appropriately qualified person.
The installation of the unit on the water side should be done in a such a way that enables future maintenance.
Both stub pipes should be connected to manual closing valves in order to cut off the device.
