Solid fuel boiler with automatic loading DEFRO AGRO DUO UNI R 30 kW

Optimal Performance and Reliability

The innovative design of the boiler allows achieving an efficiency of up to 88.7%, ensuring the maximum efficient use of thermal energy released during fuel combustion. Due to the combination of horizontal chimney and tubular heat exchangers, a high heat transfer rate is achieved.

Ease of Installation and Maintenance

The boiler is designed with installation convenience in mind: the burner can be placed either on the left or right side, allowing easy integration of the device into any heating system. The procedure for cleaning the heat exchanger and burner is performed quickly and effortlessly, making operation comfortable.

Innovative Burner with Enhanced Characteristics

The monolithic burner is distinguished by increased strength and durability. The built-in electronic protection prevents overheating of the motor responsible for fuel supply, ensuring stable and safe boiler operation.

Wide Choice of Fuel

Main types of fuel: crushed coal (fraction 5-25 mm), coal waste, biomass pellets, grain.

Additional fuel (for the upper chamber): coal, wood, sawdust briquettes.

The ability to use both combustion chambers simultaneously enhances performance and expands the functionality of the boiler.

Smart Control System

The K1Pv4 microprocessor controller with a touch screen manages four circulation pumps (heating, underfloor heating, DHW, recirculation) and regulates the operation of the mixing valve. Remote control support via GSM or the internet makes operation even more convenient.

Comprehensive Safety System

Protection against fuel tank ignition

Thermostatic fire extinguishing mechanism

Automatic extinguishing system using water fuel

Sensors controlling the opening of the fuel tank lid

Pressure stabilization system to prevent emergency situations

Energy Efficiency and Savings

The energy-saving motor-reducer with a reverse function eliminates fuel supply jamming.

Ceramic catalysts ensure stable and complete fuel combustion.

ADAPTIVE CONTROL technology automatically adjusts the boiler operation depending on the air supply volume, increasing efficiency and reducing resource costs.

Reliability and Durability

The heat exchanger is made of high-quality boiler steel with a thickness of 6-8 mm, guaranteeing its strength and long service life. The manufacturer provides a 5-year warranty on the heat exchanger, confirming the high quality and reliability of the equipment.
