The PRO offers highly economical and futureproof heating convenience using pellets and woodchips. Their modular design enables these systems to be offered with an output range of up to 1000 kW, and makes them suitable for a wide variety of applications.
Summary of test assessments:
"especially straightforward and convenient layout thanks to a unique modular design; multi-stage modular construction also ensures highest operational reliability and protects against total system downtime; highly flexible discharge and fuel selection; ..."

Fuel is gasified with a staged supply of primary air under ideal ember bed temperature conditions. The amount of combustion air and fuel charge is regulated by means of a lambda probe, so that the system achieves an optimum level of efficiency. The released combustion gases are cleanly converted into thermal energy by mixing them with secondary air in a large rotating combustion zone at a temperature of around 1300 °C. The well proven cupola design enables a perfect burnout and long dwell times.
Operational reliability is greatly improved by the multi-stage modular design, particularly where several larger buildings need to be heated. Should one of the boilers connected in series fail, the remaining boilers simply continue to operate. This protects against total failure, which is of particular importance to municipal or commercial users.
Every section of the PRO industrial system can be handled by means of a pallet truck. Its assembly is perfectly straightforward. There are no long-winded assembly and installation steps to take.
Operating the PRO industrial system is especially easy thanks to the well thought-out and user friendly touchscreen interface. All settings and scans of system data can be made in just a few steps.
Apart from their safety and economy, PRO systems offer further advantages, such as their flexible discharge solutions and the option of heating with pellets and woodchips.
Self-cleaning step grates allow users to set the ember bed height and boiler output subject to demand and relevant fuel, without risking slag forming inside the boiler. The moving step grate keeps the primary air slots clean, ensures optimum combustion and also that ash is correctly discharged.
In cleaning mode, the turbulators inside the vertically arranged tube bundle heat exchangers move up and down. This prevents deposits that reduce efficiency and safeguards consistently low flue gas losses. This feature also ensures that the boilers can operate for exceptionally long periods without requiring servicing or cleaning. All critical zones inside the boiler are cleaned automatically
Two discharge screw conveyors operating independently of each other guarantee the redundant and reliable pellet discharge from the storage room. Precise dosing, in conjunction with a specially developed industrial vacuum turbine, ensures totally reliable transportation into the 500 litre cyclone hopper. Pellets enter the combustion chamber via a pellet sluice that completely prevents any back burning or back smouldering.
PRO discharge systems feature highly efficient helical geared motors with up to 92 % gear efficiency or higher, made in series and proven in large numbers. Progressive screw conveyor technology, optimised sprung arm agitators and trough geometry plus a programmed overload monitor safeguard efficiency and operational reliability for standard woodchips G30 and G50*
