CAMINO DESIGN introduces the new and fully automated Pellet/wood chip boiler, Multiauto, series. The flexibility in solid fuels, while it burns Pellets, Wood chips and wood logs, in a combined way, and the boiler’s fully automated operation make it a pioneer in the field of heating with solid fuels.
Multiauto series can handle Pellet and all Biomass products (up to 35% humidity), wood chips as a standalone fuels or a combination with wood logs. The high efficiency and simultaneously low exhaust temperature output make the boiler very economical with very low fuel consumption and environmentally friendly, with the lowest emissions.
High Performance and output
â–¶ Flexibility in burning solid fuels, while it manages all types of Pellet and Biomass products, or wood chips and burning wood logs in parallel
â–¶ Horizontal fixed combustion system with automatic cleaning cycles
â–¶ Extremely low power consumption (375 W, maximum consumption)
â–¶ Fully automated cleaning combustion chamber and heat exchanger
â–¶ Fully automated fuel feeding system, with particular emphasis on safety as it is equipped with a preventive mechanism from returning fire in the fuel tank (backburn protection system)
â–¶ Innovative heat exchanger designed to absorb the maximum calorific value of fuel
â–¶ Extremely low flue outlet (around 125 ° C), making the boiler environmentally friendly
â–¶ Easy to use, friendly and customizable menu

1. Movable grate made of high-quality cast iron with a mechanism for cleaning and removing residues of combustion products.
2. Mechanism for removing ash residues from under the grate.
3. Ash removal conveyor in the container.
4. Combustion chamber with a protective layer of heat-resistant concrete. Additional horizontal air flow in the combustion chamber contributes to the uniform combustion of biomass.
5. High-quality cast iron plate with holes that supply secondary air, which improves combustion, reduces CO emissions and increases the degree of combustion efficiency. It is also used as a grate when burning firewood and lump wood.
6. Vertical fire-tube heat exchanger made of seamless steel tubes with turbulators.
7. Automatic cleaning system of the heat exchanger. Cleaning of the heat exchanger is carried out without stopping the boiler, by periodic reciprocating movement of turbulators.
8. Mechanism for removing ash residues from under the heat exchanger.
9. Fuel bunker.
10. The safety valve of the fuel supply system, which provides a continuous fire gap between the fuel supply conveyor and the external storage - prevents re-combustion in the fuel supply line and the fuel depot (Starvalves System (BPS).
11. Low-power electric motor (common for 3 drives).
12. Highly efficient fuel ignition system, using an electric air heater.
13. Flue gas fan with electronic control and speed sensor (Hall sensor) to regulate optimal combustion conditions in all operating modes of the boiler.
14. Electric drive of the ash removal system.
15. Ash container equipped with overflow protection system and alarm.
