Defro Epsilon F Pelletkessel 20 kW with autom. WT cleaning and ash output
EPSILON F – Compact pellet boiler for maximum heat and operating comfort
Innovative boiler design
The EPSILON F impresses with its compact boiler design, which enables efficient use of space while simultaneously being designed for maximum performance. The option to expand the pellet hopper capacity in the PLUS model provides additional convenience and flexibility.
Thanks to integrated automatic heat exchanger cleaning and ash removal, the boiler remains virtually maintenance-free. This supports reliable and continuous heating, even over extended operating periods.
Central pellet burner and TSS Twin Spark System
At the heart of the EPSILON F is a centrally controlled pellet burner, which ensures efficient and clean combustion. Automatic burner cleaning guarantees consistently optimal performance.
The innovative TSS Twin Spark System, which includes two alternately activated ignition elements, increases the safety and efficiency of combustion, ensuring stable and consistently reliable operation at all times.
Maximum energy yield and safety
A special highlight is the vertical tube heat exchanger with integrated turbulators. This technology ensures maximum energy yield and supports economical energy use in the heating system.
In addition, the vacuum sensor ensures that the required negative pressure is always maintained in the combustion chamber. The powerful induced draft fan stabilizes the combustion process and thus makes a significant contribution to the boiler's operational reliability.
Sophisticated controls and intuitive operation
The modern control system via the APC Center with touchscreen enables simple and intuitive operation of the heating system. The control system monitors and controls six pumps and two heating circuit mixers, resulting in optimal control of the heating circuits.
The factory-installed internet module connection offers additional flexibility by enabling remote monitoring and control of the system. The level sensor in the pellet hopper constantly displays the current fuel level and protects against the auger conveyor running idle.
Optional additional functions and environmental protection
Optionally, a lambda sensor can be retrofitted, making combustion even more efficient and environmentally friendly. This accessory supports optimized air supply, increasing the calorific value and reducing emissions.
An integrated particle separator as part of the BEG funding also ensures that even small particles are reliably retained, which supports air pollution control.
Versatile applications and performance
With a range of power outputs from 10 kW to 25 kW, the EPSILON F is suitable for a wide variety of applications. It offers a cost-effective and sustainable alternative to fossil fuels without compromising on efficiency.
The energy efficiency class A+ underlines the responsible use of resources and the ecological orientation of the system.
Comprehensive scope of delivery and expansion options
Included in the scope of delivery are the APC Center, the PID function, automatic maintenance functions such as heat exchanger cleaning and ash removal, as well as a factory-installed internet module. A weather-compensated heating circuit control completes the package.
In addition, various accessories are available, such as GSM modules, room thermostats and wireless communication sets.These allow for individual adaptation and upgrading of the heating system so that it also meets future requirements.
