Solid fuel boiler with automatic loading DEFRO AGRO DUO UNI R 35 kW

High Efficiency and Reliability

The modern boiler design achieves an efficiency of up to 88.7%, maximizing the thermal energy from fuel combustion. The combination of a horizontal chimney and tubular heat exchangers ensures excellent heat transfer, increasing the overall performance of the device.

Ease of Installation and Operation

The boiler is designed with flexible installation options: the burner can be installed on either the left or right side, making it compatible with various heating systems. Maintenance and cleaning of the heat exchanger and burner are simplified, minimizing time and labor costs.

Advanced Burner with Enhanced Features

The cast burner is highly durable. The built-in electronic protection system prevents the fuel feed motor from overheating, ensuring stable and safe operation of the equipment.

Flexibility in Fuel Choice

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

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

The ability to operate both combustion chambers simultaneously, which increases performance and expands the boiler's functionality.

Intelligent Control System

The digital controller K1Pv4 with a touch screen controls four circulation pumps (heating, underfloor heating, domestic hot water, recirculation) and regulates the operation of the mixing valve. The possibility of remote control via GSM and the internet makes operation more convenient.

Advanced Safety System

Protection against fuel tank ignition

Thermostatic fire extinguishing system

Automatic extinguishing system with water-fuel technology

Sensors that detect the opening of the fuel tank lid

Pressure balancing system to prevent emergency situations

Economy and Energy Efficiency

Energy-efficient motor reducer with reverse prevents fuel feed blockage.

Ceramic catalysts ensure stable and complete fuel combustion.

The ADAPTIVE CONTROL system automatically adjusts the boiler's operation based on air consumption, optimizing energy use.

Durability and Quality Guarantee

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