Pellet boiler 20 kW FOCUS (5-25 kW), ash removal

Automated pellet boiler 20 kW FOCUS with ash removal: a reliable solution for heating

Automated pellet boiler 20 kW FOCUS — is a modern equipment designed to provide efficient heating in homes, small shops and remote sites. With its help, you can significantly reduce labor costs for maintenance and increase the economic efficiency of using pellet fuel.

Main characteristics

The 20 kW FOCUS pellet boiler is designed to operate in combination with an industrial pellet burner. When creating this equipment, the emphasis was placed on:

• Heat removal efficiency: operation with high-ash pellets has been optimized, which ensures maximum productivity with minimal fuel costs.
• Auger ash removal system: automatically removes ash into a special roll-away container, increasing the intervals between cleanings.

Advantages of the boiler

1. Maximum ash pan: allows the use of high-ash fuels without frequent cleaning.
2. Integrated ash removal system: improves operating conditions by ensuring quick removal of ash from the boiler without manual cleaning.
3. Hybrid heat exchanger: combines plate and fire tube elements for maximum heat transfer, while the plate heat exchanger effectively deposits ash, which in smaller quantities ends up deposited on the fire tube section.
4. Industrial design: made of structural steel 09G2S with a wall thickness of up to 6 mm, which ensures durability and reliability of operation.
5. Modern technologies: the boiler can be equipped with a control system with the possibility of integration into a “smart home”.

Technical features

• Automatic ignition: using Japanese ceramic candles for contactless ignition of pellets.
• Fuel feed auger: ensures uniform supply and optimal combustion.
• Safety sensors: include infrared flame sensor and auger temperature sensor, which increases the level of safety.
• Ease of maintenance: wide hatches for access to the heat exchanger and ash pan are provided, as well as the ability to change the side of the door opening.

Ease of installation

The 20 kW FOCUS pellet boiler is also designed with ease of installation in mind:

• Quick release coupling system: Uses Victaulic connections developed for industrial purposes by Victaulic, simplifying the installation process and reducing the need for welding.
• Configuration flexibility: The boiler can be used in a cascade system, allowing additional boilers to be added as required, ideal for larger properties.

Energy efficiency

The 20 kW FOCUS pellet boiler can operate on various types of pellets, including agropellets with ash content up to 10%. Its output can be adjusted in the range from 5 kW to 25 kW, which allows it to be adjusted to the specific needs of the user.

Certificates and guarantees

The 20 kW FOCUS pellet boiler complies with GOST 32452-2013 (EN 15270:2007) standards and comes with a 12-month warranty, which confirms the high quality and reliability of the equipment.
