T4 Multiple award-winning Particular attention was paid to energy efficiency, durability and stability during the development of the T4. This priority was clearly confirmed when the boiler was awarded with the Austrian Ecolabel (for the wood chips and pellets) . The T4 consumes little electricity during operation, keeping the operating costs down. The new Froling T4 User-friendly, compact, economical and safe: the new T4 from Froling meets all your needs. This boiler can efficiently burn both wood chips and pellets due to its intelligent fully-automatic system. With the silicon carbide combustion...

Robust technology with intelligent features The new Froling T4 with special benefits: 1 Durable high-temperature silicon carbide combustion chamber for maximum shelf life and effective combustion with a high level of efficiency and very low emissions. Multi-part combustion grate consisting of a fixed insertion zone and the automatic tipping grate for cleaning away ash and foreign bodies. Automatic ash removal from the combustion chamber and the heat exchanger to the large mobile ash container using two separate ash screws (and a communal drive). Precise primary and secondary air control for optimal...

A well-designed inside Feature: easy to assemble on site Advantages: • quick assembly • stoker unit on the left or right as desired. The T4 is supplied assembled and wired, you just need to fit the stoker unit and connect the chosen discharge system to the rotary valve. This saves time and money. Thanks to the well-planned layout of the units and its compact design, the T4 can also be used in very confined spaces. You can select a right or left-hand stoker unit. easy to maintain combustion chamber Advantages: • pre-assembled unit • easy to service and maintain The firebricks are made of high-quality...

T4 High-temperature silicon carbide combustion chamber and perfect combustion control Advantages: • optimal emission values • economical fuel consumption • adapts automatically to varying fuel qualities The firebricks are made entirely of high-quality fireproof material (silicon carbide). The hot combustion zone ensures optimal combustion and very low emissions. Patented firebrick! The patented shaping of the firebrick stones gives the air supply in the combustion chamber particularly good airtightness without the need to use expensive wearing seals. The new shape of the stones also considerably...

A well-designed inside Feature: speed-regulated induced draught fan Advantages: • maximum ease of use • constant stabilisation of combustion • quiet and energy-saving operation The speed-regulated induced draught fan, which comes as standard, ensures the exact air quantity and constant underpressure throughout combustion. As the induced draught fan is speed-regulated, it stabilises combustion throughout and adjusts the output to requirements. The induced draught fan is also very quiet and energy-saving. flue gas recirculation (FGR) (optional) Advantages: • ideal combustion conditions • intelligent...

ash discharge system with separate ash screws Advantages: • optimal emptying • no risk of air leakage thanks to two-chamber ash container Ash is automatically emptied from the combustion chamber and the heat exchanger into the ash container using two separate ash screws, which are powered by a communal geared motor. This ensures a clear separation and absolute tightness between the combustion chamber and the heat exchanger and eliminates the risk of air leaks. Advantages: • little cleaning required • asy to empty ash container (available in three e sizes: 36 l, 54 l, 72 l) • optional ash discharge...

Intelligent upgrade Option: ESPF electrostatic precipitator Froling’s fine particulate air filter is the first electrostatic precipitator on the market especially designed for Froling boilers. Thanks to its compact design and easy assembly, it is even perfect for small boiler rooms. Thanks to its high separation rates of up to 85%, the fine particulate air filter guarantees safe compliance with future flue gas standards. Froling’s fine particulate air filter operates on the electrostatic principle. The flue gas from the boiler flows together with the fine dust particles (1) produced during combustion...

T4 Unique: Condensing boiler technology for wood chip boilers s y rate cienc .7% Effi 105 up to The Froling T4 (24 and 50 kW) is the only wood chip boiler in the world, which is also available with innovative condensing boiler technology (optional). The flue gas contains energy, which escapes unused up the chimney with conventional solutions, but an additional heat exchanger positioned on the back of the boiler makes use of it for the heating system. This increases the boiler efficiency to over 105 percent (Hu), an unprecedented level for wood chip boilers. Froling won the innovation prize at...
