Firewood and pellet boiler

Heating with firewood and pellets For more than 50 years, Froling has specialised in efficiently using wood as a source of energy. Today the name Froling represents modern biomass heating technology. Froling firewood, wood chip and pellet boilers are successfully in operation all over Europe. All of our products are manufactured in our factories in Austria and Germany, and our extensive service network ensures that we can handle all inquires quickly. The fuels: firewood (up to 56 cm) and pellets Wood is a home-grown and environmentally friendly fuel, that is highly sustainable. It is CO2 neutral...

Two systems perfectly combined The new dual fuel boiler SP Dual The SP Dual firewood and pellet boiler combines two well designed systems. It fulfills all the requirements for firewood and pellet fuels in two separate combustion chambers. Highly efficient and convenient, the SP Dual guarantees low emissions and energy costs. Pellet unit can be added any time The S4 Turbo F with pellet flange is the ideal solution for people who are currently only burning firewood. It can easily be converted to a dual fuel boiler by fitting the pellet unit at any time.

Broadband lambda probe for optimal combustion (2) Speed-regulated, low-noise induced draught fan for maximum ease of use (3) WOS system (Efficiency Optimisation System) as standard, for high efficiency and user- friendly cleaning from outside Optional with automatic WOS-Technik (4) Servo-motors as standard for automatic control of primary and secondary air (5) Carbonisation gas extraction system prevents smoke escaping during reloading 18 Cladding to protect the inner wall of the boiler and for a longer service life ^ Large fuel loading chamber for logs up to 56 cm in length guarantees...

Lambdatronic S 3200 control with 7” touch display and innovative bus technology Double slide valve system for maximum burn back protection Spacious pellet container with stoker screw and external suction module Water-cooled pellet flange with downward pointing design for safe operation High-quality water-cooled pellet burner with sliding grate for automatic ash removal and cleaning Practical, convenient ashcan for simple, dust-free emptying and long cleaning intervals Fully insulated to minimize radiant heat loss Large fuel loading chamber doors for easy and convenient loading of firewood

Advantages: • Easy filling • Long lasting combustion • Long service life The SP Dual allows burning of firewood up to a length of 56 cm for all system output sizes. It is filled conveniently from the front of the unit and due to a large fuel loading chamber long refilling intervals are possible. Often it is only necessary to fill the boiler once a day. A cladding protects the interior walls of the boiler, guaranteeing a long service life. pointing downward Advantages: • Safe operation • Pellet unit can be additionally fitted at any time The downward pointing design of the pellet flange ensures...

SP DualFeature: Automatic ignition and continued operation Advantages: • No additional equipping required • Automatic change between firewood and pellets The firewood can be ignited automatically using the pellet burner. Due to the separate combustion chamber design, it is possible to change between firewood and pellets when needed. When the firewood has burned down and is not replenished within a set period of time (0-24hrs), heating is automatically continued with pellets if required. The SP Dual is designed to automatically interrupt pellet operation and to start firewood burning immediately when...

Intelligent details Feature: Advantages: Speed-regulated induced draught fan • Maximum ease of use • Problem-free boiler start • Constant stabilisation of combustion Das serienmäßige, drehzahlgeregelte Saugzuggebläse sorgt für die exakte Luftmenge und permanenten Unterdruck während der gesamten Verbrennung. Die Drehzahlregelung des Saugzuggebläses stabilisiert somit die Verbrennung über die gesamte Brenndauer und passt die Leistung an die Erfordernisse an. Zudem arbeitet das Saugzuggebläse äußerst leise und stromsparend. Feature: Quick heating-up (with manual ignition) Advantages: • Just load...

Feature: WOS system as standard Advantages: • 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. Feature: Water-cooled pellet burner with automatic sliding grate Advantages: • high efficiency •...

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...

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 and complete emptying...
