ATMOS screw conveyors – Efficient transport of wood pellets

ATMOS screw conveyors are an ideal solution for the reliable and efficient transport of wood pellets from the storage room directly to the boiler. They offer a wide selection of models and lengths to meet the individual needs of modern heating systems. With a transparent conveyor tube, various performance classes, and easy integration, they are the perfect addition to any pellet heating system.

ATMOS DR screw conveyor – For pellet boilers up to 25 kW

The ATMOS DR screw conveyor is particularly suitable for smaller pellet heating systems and ensures reliable pellet transport. This model is often used in combination with sheet metal silos, textile storage tanks, or storage rooms. The straight-running design guarantees a stable and even supply of fuel to the boiler, improving both efficiency and operational reliability.

A unique feature of the ATMOS DR screw conveyor is the transparent conveyor tube. This allows the user or system operator to check the pellet level in the tube at any time without having to open the system. A clear advantage in terms of maintenance and monitoring! Available in various lengths from 1.5 to 4 meters, this screw conveyor is flexible in its use.

With a feed rate specifically tailored to pellet boilers up to 25 kW, the ATMOS DR screw conveyor is ideal for small and medium-sized heating systems. It is compatible with ATMOS pellet boilers of the P14, P21, P25, P15, and P20 models.

ATMOS DRA screw conveyor – For pellet boilers from 26 to 80 kW

For larger heating systems, the ATMOS DRA screw conveyor offers an excellent solution. With a higher feed rate, this model was specifically developed for pellet boilers with an output between 26 and 80 kW. Like the smaller DR model, the DRA screw conveyor is often used in conjunction with sheet metal silos, textile storage tanks, or on-site storage rooms – but for more demanding applications.

A key difference lies in the fixed length of the DRA screw conveyors. Unlike the DR models, these variants cannot simply be shortened, which must be taken into account when planning the heating system. Available in lengths from 1.7 meters to 5 meters, they offer the necessary flexibility to bridge even longer distances between the storage area and the boiler.

The ATMOS DRA auger is the perfect choice for the more powerful pellet boilers such as the P30, P40, P50 and P80 models.

Important advantages of ATMOS screw conveyors

Regardless of the model, ATMOS screw conveyors offer several advantages that simplify plant operation and guarantee a long service life:

• Reliable and even pellet feeding.
• Transparent tubes for easy checking of the pellet level.
• Various length options to adapt to individual requirements.
• Compatibility with a wide range of ATMOS pellet boilers.

The screw conveyors are durable and low-maintenance, making them a worthwhile investment for any pellet heating system operator.

Which screw conveyor is right for your needs?

The choice of the appropriate screw conveyor depends on the output of your pellet boiler and the distance between the storage area and the boiler. For smaller heating systems up to 25 kW, the ATMOS DR screw conveyor is ideal. It allows for flexible adaptation thanks to its availability in various lengths and is easy to integrate into existing systems.

For larger heating systems, the ATMOS DRA auger conveyor offers the necessary conveying capacity and range to ensure a consistent pellet supply. However, please note that this auger conveyor has fixed lengths and should therefore be selected carefully during planning.

Conclusion – Optimal efficiency and functionality

ATMOS screw conveyors represent an excellent solution for automatic pellet feeding in modern heating systems. Whether for smaller household boilers or larger heating systems – with the right choice between ATMOS DR and DRA screw conveyors, efficiency, convenience, and cost reduction are optimally combined.

Discover the versatile applications of ATMOS screw conveyors and equip your heating system for the future!
