PELLET BOILER • ntegrated particle separator I (electrostatic precipitator) available as an option • Online boiler control via app • " touch display with LED 7 status display BETTER HEATING INNOVATIVE AND CONVEN

ENVIRONMENTALLY RESPONSIBLE HEATING, ECONOMICALLY REWARDING The price changes for different energy sources in recent years show the benefits of wood pellets: the environmentally clean way of heating is also economically attractive. Wood is a renewable energy source that is also CO2-neutral. Pellets are made of natural wood. The large quantity of wood shavings and sawdust produced by the industry are compacted and pelleted without being treated beforehand. Pellets have a high energy output and are easy to deliver and store. These are just some of the advantages that make pellets the perfect...

PELLET BOILER PT4e FOR EVEN MORE CONVENIENCE 7" touch display with LED status indication for simple and intuitive operation Large ash container for long emptying intervals NEW! 7" touch display with LED status illumination Pellet boiler can be retrofitted with integrated particle separator (electrostatic precipitator) at any time

Multi-part combustion grate consisting of a fixed insertion zone and 2-part automatic tipping grate Large pellet container Two multi-chamber rotary valves Geared motor for stoker screw

A WELL-DESIGNED HOME FOR GREATER CONVENIENCE Easy to assemble on site The PT4e is supplied assembled and wired. You just need to fit the stoker unit and connect the chosen discharge system to the supply bin. This saves time and money. Thanks to the wellplanned layout of the units and its compact design, the PT4e can also be used in very confined spaces. Advantages: Quick installation Pre-wired Return temperature control already integrated (ex works) Speed regulated EC induced draught fan The speed-regulated EC induced draught fan ensures the exact air quantity for combustion. As the induced...

Cleaning of all heat exchanger pipes Heat exchanger with automatic cleaning (WOS) of all passes and lower drive The WOS (Efficiency Optimisation System) consists of special turbulators, which are placed in the heat exchanger pipes (NEW! Now from first pass) and allow automatic cleaning of the heating surfaces. Clean heating surfaces ensure greater efficiency and thus fuel savings. Advantages: Greater efficiency Fuel economy rive mechanism in cold zone (low thermal D load) Permanently integrated return temperature control The room temperature control integrated as standard avoids unnecessary...

INTELLIGENT DESIGN IN EVERY DETAIL Flue gas recirculation (FGR) The flue gas recirculation system (FGR) mixes part of the flue gas with the combustion air and returns it to the combustion zone. The FGR optimises combustion and performance, and also reduces NOx emissions. The lower combustion temperatures offer added protection for flame-swept parts. Advantages: it Precise adjustment via air actuators it Ideal combustion conditions i. Intelligent control of air quantity Optional integrated particle separator (electrostatic precipitator) The optionally available particle separator...

High-temperature silicon carbide combustion chamber and perfect combustion control 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! PRIMAR Y AIR 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 simplifies the maintenance of the combustion chamber as they can be removed easily. Advantages:...

SPECIAL TIPPING GRATE TECHNOLOGY WITH 110° TIPPING GRATE INCLINATION Two-part combustion grate consisting of a fixed insertion zone and automatic tipping grate guarantee energy-saving operation and lowest emissions. Due to the 110° inclination, the ash is completely emptied from the tipping grate and discharged into the large-volume mobile ash container by means of the ash screw. CALCULATING THE FUEL REQUIREMENT The fuel requirement depends on the fuel quality. The following rule of thumb can be used to make a rough estimate: 1 m3 per kW heating load Pellets fuel data Length Diameter Water...

EXTRA CONVENIENCE WITH THE EXTERNAL ASH BOX With automatic ash removal, the ash is fed into an external ash container. The clever locking mechanism makes it quick and easy to remove the ash container. Side carrying handles for quick handling Easy removal by means of transport rollers The side carrying handles also allow the ash box to be transported comfortably by pallet forks (e.g. a front loader, forklift truck, etc.) Practical hydraulic device for transporting with the tractor and easy emptying (tipping) Optional: Ash discharge system with bin For added convenience, ash can optionally be...

4 probe manual suction system The RS 4 manual pellet suction system creates more space in your fuel store. 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. The switchover between suction probes is manual. As a rough rule of thumb: Plan for one suction probe for every 1 m² pellet storage area. External suction module An external suction module is used for automatic fuel feed from the fuel store to the pellet container. The suction module can be fitted in any position in the return air line. Fully automatic...
