Monoblock pellet boiler 90 kW FOCUS, power range (8-90 kW)

Automatic monoblock pellet boiler 90 kW FOCUS 

An economical monoblock pellet boiler 90 kW, developed on the principle of "all in one", stands out not only for its elegant body made of polished stainless steel with perfectly balanced proportions, but also for its unique engineering solution that takes into account all modern requirements for heating systems. With its help, you can organize a full-fledged heating system for private houses, workshops, small shops, cafes or offices.

Monoblock pellet boiler 90 kW includes all key elements: a pellet bin, an automatic feed and ignition system, a control and monitoring system, Internet control and a weather algorithm that automatically regulates the coolant temperature depending on the outside temperature. It also has a built-in mixing unit based on an automatic 4-way valve for regulating the temperature of heating devices (radiators, heated floors, air convectors) and the ability to connect hot water supply (HWS).

The purchase of such a boiler eliminates the need for additional automation, safety group, hydraulic units and weather regulators. The installation specialist will perform the connection in one cycle, integrating it into an existing or new multi-circuit heating system. The 90 kW monoblock pellet boiler is connected to the heating system without welding.

The 90 kW monoblock pellet boiler from TM "FOCUS" was specially created for heating large private houses, industrial buildings, remote facilities, workshops, indoor parking lots, exhibition or industrial hangars with an area of up to 900 m². In insulated facilities, this figure can be increased to 950 m². The boiler provides automatic switching on and off, as well as heating adjustment depending on the needs of the room.

The boiler design is focused on the most efficient heat removal, achieved due to the high efficiency of the flare burner. The burner supports the combustion of both wood and agro pellets with a high ash content (up to 10%). Thanks to the pyrolysis afterburning technology of secondary combustion products, emissions are improved and the efficiency of the system increases, which makes the 90 kW monoblock pellet boiler a more interesting choice for consumers against the background of offers from other manufacturers.

The burner also features a self-cleaning grate system and automatic ignition with flame control, which is controlled by a glow sensor. The control system literally “sees” the flame and maintains it independently, which simplifies the operation of the boiler and makes it an economically advantageous solution for users using commercially available fuel pellets.

Monoblock pellet boiler 90 kW: design features of the boiler

1. 1. Material and strength:Structural steel 09G2S with a wall thickness of 6 mm in the heat exchange part and 4 mm in the water jacket, which guarantees the durability and high strength of the boiler.
   2. High heat exchange efficiency:Heat exchange area - 7.3 m², providing fast and efficient heat removal. Hybrid heat exchanger (plate and fire-tube) optimizes heat transfer and reduces heat loss.
   3. Thermal insulation:Basalt mineral wool 50 mm thick prevents excessive heat loss and increases the efficiency of the boiler.
   4. Stainless steel casing:Made of polished stainless steel AISI 201, giving the boiler a modern appearance and resistance to corrosion. The 90 kW monoblock pellet boiler is a version of the boiler room capable of supplying heat in complete autonomy.
   5. Sectional door:Provides easy access to the burner, heat exchanger and ash pan for regular maintenance. Adjustable hinges and locks provide a tight fit of the door and the ability to change the side of its opening for ease of installation.
   6. Large ash pit:Designed for several days of operation without the need for frequent cleaning, even when using fuel with high ash content.
   7. Built-in bunker:Hopper capacity - 240 kg pellets, providing at least a day of autonomous operation at maximum power. The cover on pneumatic shock absorbers makes loading fuel easier and reduces the effort required to open it.

The FOCUS 90 pellet monoblock boiler has a number of significant advantages that make it the optimal solution for various types of facilities, including households, shops and remote buildings. One of the key advantages is its versatility in fuel use. The boiler can operate on clean wood pellets, as well as agropellets with an ash content of up to 10%, which allows the use of fuel pellets from waste such as sunflower, corn, buckwheat, rice, furniture waste and straw. This significantly expands the possibilities for saving on fuel, since cheaper and more accessible types can be used.

In addition, the FOCUS 90 boiler is designed for optimal heating of various objects, including households and commercial premises, which makes it a universal solution for various needs. The built-in hopper and automatic fuel supply and burner cleaning functions provide a high degree of autonomy of the boiler, allowing it to operate for a long time without the need for frequent intervention from the user.

Monoblock pellet boiler 90 kW is also equipped with automatic ignition and cleaning systems, which significantly reduces maintenance and operating costs. This makes it not only convenient to use, but also an economically advantageous heating solution, especially in cases where it is necessary to minimize operating and maintenance costs.
