PRO FLEX INDUSTRIAL SYSTEM
175 to 1000 kW
LARGE PELLET SYSTEM
The PRO FLEX offers highly economical and futureproof heating convenience using pellets. 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.
Benefits
Highly efficient combustion
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.
HIGHEST OPERATIONAL RELIABILITY
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.
Modular design
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.
STRAIGHTFORWARD OPERATION
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.
Flexible application options
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.
Highest level
of convenience
It's all a matter of technology
Industrial step grate technology
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.
Self-cleaning heat exchanger
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
Highest operational reliability
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.
FLEX
Guntamatic Flex discharge units are suitable for particularly large, intensively used, storage facilities.
The discharge screw conveyor of the vacuum discharge system has been designed for efficiency and a long service life. It offers a highly reliable operation as well as low cleaning effort,
and discharge from stores with sloping floors. Where the sloping floors are made on site, this is also a particularly affordable solution.

Futureproof and economical – woodchips and pellets are amongst the most affordable fuels available today. At the same time, advanced woodchip and pellet heating systems operate with great efficiency and in excellent balance with the environment.
Highly efficient combustion: the demand-dependent adjustment of the ember bed height allows pellets and woodchips to be optimally burned, both in terms of ecology and economy.
