Solid fuel boiler on manual loading KRONAS ALMAX D 17 kw

The modern Almax Class D (KTH) boilers are an updated series of residential and industrial units known for their simple yet efficient design. All models have high performance characteristics, with the 12 kW model as an example.

Reliable solid fuel boilers require a connection to an electricity source. To ensure independence from electricity, a mechanical draft regulator can be used.

The Almax Class D (KTH) 12 kW boiler is made from European heat-resistant steel, ensuring a durable and reliable welded assembly. All units are protected from corrosion due to the stainless properties of the steel and a protective paint layer on the exterior.

Design Features of Almax Class D Boilers:

• Spacious combustion chamber with a volume depending on the model's power.
• Four-pass convection heat exchanger for efficient heat transfer.
• Combined grate bars for loading solid fuel.
• A connector for installing a safety valve or safety group, as well as a separate connector for fast water drainage.
• Several doors for servicing the unit: for loading fuel, cleaning the convection part, and inspection doors for servicing the grates and ash parts.
• Option to install a pellet burner by removing the cast iron grates placed on tubes on both sides of the combustion chamber.

The Almax Class D boiler with a metal heat exchanger includes a controller that constantly measures the water temperature, and the data is used to control the fan operation.

Main Advantages of Almax Class D Boilers:

• Choice of models based on required power and heated area.
• High efficiency of 86% or higher.
• Operation without electricity using a mechanical draft regulator.
• Effective heat exchange with a multi-pass convection heat exchanger.
• Modern equipment including a fan and microprocessor control from a Polish brand.
• Secondary air nozzles around the combustion chamber.
• Double thermal insulation of the doors with heat shields.
• Stylish and aesthetic appearance.
• Option to retrofit the boiler into a fully operational pellet boiler with additional purchases such as a burner, auger, and hopper.
• Heat exchanger and body are made of heat-resistant steel with 6 mm thickness and 5 cm thermal insulation on the exterior.

Operating Features of Almax Class D Boilers: Almax Class D boilers (KTH) are universal and can be installed in residential, commercial, and industrial buildings with areas of up to 120 m².

These boilers are designed for installation in buildings with central heating and can work with the following types of fuel:

• Firewood
• Coal (brown, anthracite)
• Fuel briquettes (sawdust, peat)
• Chunky peat
• Woodworking waste

The boiler design ensures high efficiency even when using low-calorific fuels. The highest efficiency is achieved when burning coal.
