ATMOS DC 30 SX

Product detailed description

The ATMOS DC 30 SX is a wood-burning boiler designed for installation in heating systems that require a high-efficiency solution for burning solid fuel. It is commonly used in residential and commercial buildings where a reliable and environmentally friendly heat source is required. The boiler is suitable for integration into central heating systems with return water temperatures above 65 °C. Installers and technicians working with solid fuel systems will find this model suitable for installations where long burn times and high thermal output are required.

Its gasification combustion system allows for the efficient burning of large logs, reducing the frequency of refuelling. The boiler is designed to operate with a chimney draft of 24 Pa and is compatible with fuel wood of specified dimensions and moisture content. The cooling loop and exhaust fan help prevent overheating and ensure safe operation. The system is suitable for use in buildings with dedicated boiler rooms and appropriate flue systems.

Technical parameters

The technical parameters of the ATMOS DC 30 SX are essential for proper sizing and system integration. The fuel capacity of 95 dm³ allows for extended burn times, while the 58 L water volume ensures stable heat transfer. The minimum return water temperature of 65 °C is important for system efficiency and must be maintained to prevent condensation. The required chimney draft of 24 Pa must be verified during installation to ensure safe and efficient operation.

Installation and connection

The installation of the ATMOS DC 30 SX requires careful planning and adherence to technical specifications. The boiler must be placed in a well-ventilated room with sufficient space for maintenance and fuel handling. The fuel hopper is designed for logs up to 530 mm in length, so the fuel supply system must accommodate this size. The boiler is connected to the heating system via standard pipe connections, and the exhaust system must be sized to handle the required draft of 24 Pa. It is important to ensure that the chimney is properly sealed and insulated to prevent heat loss and maintain the required draft.

Common installation mistakes include incorrect chimney sizing, failure to maintain the required return water temperature, and improper positioning of the boiler in relation to flue connections. Installers should verify that the fuel hopper is accessible for regular refuelling and that the cooling loop is correctly integrated to prevent overheating. The exhaust fan must be connected to a power supply and tested to ensure it operates without interference.

Compatibility and accessories

The ATMOS DC 30 SX is compatible with central heating systems that use return water temperatures above 65 °C. It is designed to work with fuel wood of specified dimensions and moisture content, so fuel storage and handling systems must be appropriate. The boiler does not require additional components for basic operation, but it is recommended to install a chimney damper for better control of the exhaust flow. No related products are required for standard installation.

Technical background for designers

The ATMOS DC 30 SX operates on the principle of gasification combustion, where wood is burned in two stages to maximise efficiency and reduce emissions. The fuel hopper is constructed from 6 mm thick steel and is equipped with a gasification nozzle to direct air flow and promote complete combustion. The combustion chamber is lined with ceramic refractory bricks to withstand high temperatures and ensure even heat distribution. The exhaust fan helps remove combustion gases and prevents smoke from entering the room.

The boiler is constructed from high-quality steel with thicknesses ranging from 3 to 8 mm, ensuring durability and resistance to thermal stress. The cooling loop is an important feature that prevents overheating and protects the boiler from damage. The system is designed to integrate into existing heating systems with minimal modifications. The efficiency of 89.9% is achieved through the combination of gasification combustion and the use of an exhaust fan to optimise air flow and heat transfer.

Service and operation

Regular maintenance is essential for the long-term performance of the ATMOS DC 30 SX. The fuel hopper should be inspected for blockages and cleaned as needed. The exhaust fan and chimney should be checked for proper operation and cleaned to prevent soot buildup. The cooling loop should be monitored to ensure it is functioning correctly and preventing overheating. The boiler is equipped with a combustion thermostat that automatically shuts down the system when the fuel is exhausted, reducing the risk of damage.

Service intervals are not specified in the technical data, but it is recommended to perform annual inspections and cleaning of the combustion chamber and exhaust system. The ceramic refractory bricks should be inspected for wear and replaced if necessary. The exhaust fan should be tested for proper operation and cleaned to prevent dust accumulation. The chimney damper should be adjusted as needed to maintain the required draft of 24 Pa.
