ATMOS AC 16 S

Product detailed description

The Atmos AC 16 S is a high-efficiency solid fuel boiler designed for installation in industrial and commercial heating systems. It is commonly used in facilities requiring continuous heat generation from solid fuels such as brown coal briquettes, bituminous coal and firewood. The boiler is suitable for integration into central heating systems where a reliable and cost-effective heat source is required. Installers should consider the boiler's minimum return water temperature and chimney draft requirements when planning the installation.

The technical parameters of the Atmos AC 16 S are essential for correct sizing and system integration. The 18 kW output determines the boiler's suitability for medium to large heating systems. The 37 L water volume and 273 kg weight are important for assessing space requirements and structural support. The 50 W electrical power consumption and 230/50 V/Hz supply voltage are key for electrical system planning.

Installation and connection

Installation of the Atmos AC 16 S requires careful planning of the flue gas extraction system and water circuit connections. The boiler must be connected to a chimney with a minimum draft of 16 Pa to ensure proper flue gas removal. The water circuit should be connected using standard pipe sizes with appropriate thread types for the installation location. Installers should verify that the return water temperature is at least 65 °C to maintain efficient operation. Common installation mistakes include incorrect chimney draft settings and inadequate space for fuel loading and ash removal.

Compatibility and accessories

The Atmos AC 16 S is compatible with standard central heating systems and can be integrated with radiators, underfloor heating and hot water storage tanks. Additional components required for a complete system include a chimney with the specified draft, fuel storage for briquettes or firewood, and a control system for monitoring boiler operation. No specific related products are recommended for this model.

Technical background for designers

The Atmos AC 16 S operates on a generator gasification principle with a flue gas extraction fan. The boiler body is constructed from high-quality steel plates (3-6 mm thickness) to ensure durability and heat retention. The design features two chambers stacked vertically, with the upper chamber serving as a fuel storage and the lower chamber as the combustion chamber and ash pit. A patented rotating grate between the chambers enables efficient gasification and ash removal. The primary and secondary air is preheated to improve combustion efficiency and reduce emissions. The boiler's Class 5 combustion rating (according to EN 303-5) indicates compliance with high environmental standards.

Service and operation

Regular maintenance of the Atmos AC 16 S includes ash removal and inspection of the combustion chamber. The rotating grate allows for convenient ash removal, with coal ash typically requiring daily removal and wood ash requiring weekly removal. The cooling circuit helps prevent overheating and protects the boiler from damage. The flue gas thermostat automatically shuts down the boiler when fuel is exhausted. No specific service intervals are provided in the technical data.

Frequently asked questions

Can the Atmos AC 16 S be used with firewood as the primary fuel?
Yes, the boiler can burn firewood with a maximum length of 250 mm as an alternative fuel. However, brown coal briquettes are the recommended fuel for optimal performance.

What is the minimum chimney draft required for the Atmos AC 16 S?
The boiler requires a minimum chimney draft of 16 Pa to ensure proper flue gas removal and safe operation.

How often should the ash be removed from the Atmos AC 16 S?
When burning coal, ash should be removed daily. When burning firewood, ash removal is typically required once per week.

What is the maximum fuel storage capacity of the Atmos AC 16 S?
The boiler has a fuel hopper capacity of 45 dm³, allowing for extended operation without frequent refueling.
