High volumes of heat right where you need it and at low cost
Master SF range – indirect oil-fired heaters
The SF series are vertical or horizontal indirect-fired heaters. They can be supplied with or without oil, propane or natural gas burners.
They are designed to provide fast, efficient and economical heating for volumes or assemblies of up to 35,000m³.
They are particularly well suited to heating industrial, agricultural or public buildings, workshops or garages, warehouses, shops, reception or exhibition halls, and sports halls.

High performance
Whether used for direct air discharge (directional heads) or connected to a duct network, SF units offer first-class performance: power ratings ranging from 60.7 to 1,160 kW, efficiencies of over 90% across the range, and air flow rates of between 4,300 and 72,000 m³/h.
These features give them a particularly favourable cost/efficiency ratio.
Rational
Simple to install, SF generators produce immediately available heat for a moderate investment in relation to the volume heated. Thanks to their high-pressure centrifugal fan, they can heat several rooms with a single generator via a network of ducts. Their high airflow rate means that temperatures rise quickly, making it unnecessary to keep the generator running when the room is unoccupied. The exceptional efficiency of SF series heaters (over 90%) is a guarantee of efficiency and energy savings.
Quality
SF heaters are top-of-the-range appliances, with everything in their design and construction designed for maximum efficiency and reliability:

- Refractory stainless steel reinforced chamber bottom
- Heat exchanger with stainless steel flue gas turbulators (firebox guaranteed for 5 years)
- High-pressure centrifugal fan with double intake
- Complete chassis in galvanised sheet metal
- Body in 10/10 mm thick pre-painted electro-galvanised sheet metal
- Thermal insulation of panels
- Integrated watertight electrical panel
- Inspection hatches for easy maintenance of the firebox/exchanger assembly and flue gas manifold
- Bi-thermostat "fan-limit" doubled with an independent overheating thermostat
