Large fuel loading chamber for half-metre pieces (up to 56 cm) with hot cladding Advantages: • Easy loading • Long combustion time • Long lifespan With 15 or 20 kW outputs, the SP Dual compact allows burning of firewood up to a length of 56 cm. Despite its compact design, the SP Dual compact has long reloading intervals and is already suitable for storage tank sizes from 825 litres. The aprons (hot cladding) protect the interior walls of the boiler, guaranteeing a long service life. pointing pellet flange Advantages: • Safe operation • Pellet unit can be retrofitted at any time The downward pointing...

Feature: Automatic ignition and continued operation Advantages: • No refitting required • Automatic change between firewood and pellets The firewood can be ignited automatically using the pellet burner. The two separate combustion chambers make it possible to change flexibly between firewood and pellets. If the firewood has burnt up and is not replenished within the time you specify (0-24 h), heating is continued automatically if heat is required. If you open the loading chamber doors and insert more firewood, the pellet operation is interrupted and the SP Dual compact switches automatically...

Feature: Speed-regulated induced draught fan Advantages: • Maximum ease of use • Smooth boiler start • Constant stabilisation during combustion The speed-controlled induced draught fan is a standard component of the unit, which further enhances the reliability of the SD Dual compact. This means that the boiler can be started easily even if the chimney is cold. The speed regulation device in the induced draught fan stabilises combustion throughout the heating process and adjusts the output according to requirements. Feature: unique air duct system Advantages: • Regulated supply of air for...

SP Dual compact H IONAL WIT NEW! OPT IK OS-TECHN AUTOM. W Feature: Advantages: WOS system as standard • Even more efficient • Easy cleaning from outside • Fuel economy We never compromise on convenience. The WOS (Efficiency Optimisation System), which comes as standard on the SP Dual compact, consists of special turbulators, which are placed in the heat exchanger pipes. The lever arm mechanism ensures easy cleaning of the heating surfaces from the outside. An additional benefit of this mechanism is that it ensures higher efficiency and fuel savings. Automatic ignition Advantages: • quiet operation...

Feed systems RS 4 / RS 8 pellet suction system easy to assemble no sloping slides necessary in bunker more store space (30%) automatic switching between the probes automatic backwash maintenance-free system The NEW RS 4 / RS 8 pellet suction system creates more space in your store space. Thanks to the fact that the suction probes are flexible in terms of location, it is possible to make optimal use of every room shape. Rule of thumb: Plan for one suction probe for every 1 m² pellet storage area. It automatically selects 4 or 8 suction probes in specified cycles, it is controlled by the pellet...

Suction screw system The bag silo system is a flexible, simple way of storing pellets. Available in 9 different footprints (from 1.5 m x 1.25 m to 2.9 m x 2.9 m) with a capacity of between 1.6 and 7.4 tonnes, depending on the bulk density. There are other advantages to using a bag silo. It is easy to assemble and dustproof. You can also fit rainproof and sunproof covers and install the silo outside. The Froling screw suction system is the ideal solution for rectangular rooms with front-end removal. The deep and horizontal position of the discharge screw means the space in the room is used optimally...
