Linder & Sommerauer: SL 50/150 Biomass Boiler
The SL 50/150 series combines impressively high heat output, optimum combustion levels, total simplicity of use and straightforward maintenance.

The range is capable of burning wood chips or wood pellets and can achieve heat outputs of 50 to 150kW from a single unit. Up to 6 multiple units can be combined in a cascade up to 900kW.
Every single Lindner and Sommerauer boiler comes with a 5-year warranty that covers all moving parts and electronic controls.

Total Efficiency
We only supply the finest biomass boilers which is why we are proud to bring Lindner and Sommerauer boilers to our customers. They offer some of the highest efficiencies on the market with rapid recovery rates, thanks to innovative steel heat exchangers.
You can expect perfect combustion in the SL 50/150 series, at gasification temperatures in excess of 1,200°C.
Wood Chip Fuel Delivery Systems

Opt for a single agitator of up to 6m in length or multiple agitators on a single unit. Being able to deliver wood chips in such a manner allows you to construct large stores, making bulk buying cost-effective and contract chipping an option.

What’s more, these delivery systems can be fitted to the left or right side of the boiler, allowing total flexibility in the layout and design of your plant room.



This system also comes with a two-piece auger channel (available in lengths up to 15m) and a separate lid for ease of maintenance.

The auger is one solid piece to allow maximum strength and no points of weakness. This means your fuel store can be located underground, in a garage or outbuilding up to 15m away, whatever suits your project and budget the best.
Wood Pellet Fuel Delivery Systems

For total simplicity, wood pellets can be blown into your fuel store via a vacuum tube. Ask us about fuel store solutions, we can provide plenty of ideas and options.

If you have any questions about the best way to specify fuel delivery and storage systems, please don’t hesitate to get in touch with us.
Self-Cleaning

The four rows of vertical cylinders in the steel heat exchanger contain sprung, moving turbulators which operate during the cleaning cycle to prevent the buildup of deposits on the heat exchanger surface, ensuring maximum heat transfer and reduced efficiency loss.
Easy to Use
Your SL 50/150 biomass boiler comes with an electronic touch screen control panel fitted as standard.

This sleekly designed, modern interface allows you complete control over timers, thermostats and other aspects of the biomass boiler’s controls.

Safe and Reliable

When you choose Lindner and Sommerauer, you know you’re choosing safety, durability and reliability. The bevelled, direct drive gear boxes are designed with silicon carbide-coated ball bearings and the system features no chains that could break or snap. What’s more, they all come with a 5 year warranty as standard.

The auger motor drive closes if the system shuts down, providing protection against burn back. And the firebox is designed with durable silicon carbide tiles that offer significantly higher resistance to wear than fire bricks.

Finally, the discharge auger control sensor prevents the agitator disc rotating when not required to minimise energy use and power consumption.
Low Ash Volumes
The amount of ash produced to the volume of fuel is around 5%. What little ash there is gets transferred into large ash bins that are easy to remove.

The ash generated by your biomass boiler is useful as a fertiliser due to high levels of nitrates.
