AGRO Multi










BOILER DESCRIPTION

Wide range of power and ecology of use

AGRO Multi boiler is intended for combustion of ecological fuel in form of pellet made of non-wood biomass. Raw materials for its production are e.g.: straw, Miscanthus, reed, kernels and seeds, olive residues and nut shells. Its optimized combustion process is ensured by innovative Multi PSQ burner [1]. Wide range or power allows limiting heat losses.

Automatic operation

AGRO Multi is equipped with a new, multifunctional and simple controller ecoMAX 910 [2], which works with the outside sensor and room thermostat ecoSTER. The standard equipment of the controller includes 5 pumps: (central heating, domestic hot water, circulation pump, transfer pump and pump of the mixer) and two actuators of the mixing valves. Wide operation range of the controller allows setting various levels of the temperature in separate heating systems. For example: in floor heating and room heaters system. The ecoMAX 910 controller is equipped with a convenient graphical display and several options for additional equipment. Room controller ecoSTER TOUCH and the internet module ecoNET 300, giving an option of the remote preview, change of parameters and even technical support are the most important components.

Full protection of combustion process

Operational safety and protection of the device itself are ensured by a series of protections. Automatic fire suppression system, the so-called fire-fighter, is a basic equipment of the boiler. The sensors permanently control the temperature of water in the boiler, temperature of screw and fuel container. If the irregularities or damage of any of the sensors in the system is detected then the system gives an alarm signal and shuts down the feeder and fan. Jamming of the screw in the feeder results in mechanical rupture of split pin what protects the motoreducer against destruction. Another protection in AGRO Multi is a sensor protecting against retraction of glow to the feeder and flame suppression system when feeder pipe reaches a temperature of 90°C.

SERVICE MANUALS

Primary fuel: NON-WOOD PELLET

Non-wood pellet — granules produced from wastes from agricultural and forestry production. It is produced from grains, green stems, hay, energy crops and any other waste biomass, which can be combusted. This fuel is easy to transport and store, its price is considerably lower than price of wood pellet.

high power and small dimensions

PEREKO boilers have high heating power with relatively small dimensions. It is also possible to install them in smaller boiler rooms.

elongated flue gas
circulation

Elongated flue gas circulation ensures higher efficiency of the equipment and lower fuel consumption.

“fire-fighter” protection in a standard

Additional protection protecting against overheating and possible flashback to the charging hopper.

Multi PSQ burner

Steel burner Multi PSQ with a trough feeder has an innovative design allowing combusting pellet made of non-wood biomass.

option to operate via the internet

An additional module allows controlling operation of the boiler via the internet.
