AZPU Compact Pellet Tank H0280

Product detailed description

The AZPU compact pellet tank is commonly used in small boiler rooms or retrofit applications where the boiler and fuel storage must be positioned in close proximity. This design is typical in residential or small commercial buildings where the boiler room is constrained by architectural limitations. The tank is integrated into the fuel delivery system of pellet-fired boilers, ensuring a continuous and reliable supply of fuel to the burner. The system requires careful planning to ensure the tank is installed in a location that allows for easy access for refilling and maintenance while maintaining a safe distance from flammable materials.

Technical parameters

Weight	64.4 kg
Code	H0280
Brand	Atmos

The tank is available in two capacities: 240 L and 400 L. These sizes are suitable for boilers with moderate fuel consumption rates, where the tank can be refilled regularly without requiring large storage volumes. The inclusion of the DRA 25 conveyor with a 1.7 m length and 25 W gearbox ensures that the system can deliver fuel to the burner efficiently. These parameters are important for determining the suitability of the tank for a specific boiler model and the frequency of refills required during operation.

Installation and connection

The AZPU tank is installed in close proximity to the boiler, typically within a few meters, to minimize the length of the conveyor and reduce the risk of fuel blockages. The conveyor is connected to the boiler's fuel inlet using standard fittings. The installer must ensure that the conveyor is aligned correctly to avoid mechanical stress on the gearbox and conveyor belt. Common installation mistakes include incorrect alignment of the conveyor, which can lead to premature wear, or insufficient clearance around the tank, which can hinder access for maintenance. The tank must be placed on a stable, level surface to prevent fuel spillage or uneven distribution within the tank.

Compatibility and accessories

The AZPU tank is specifically designed for use with pellet-fired boilers that have been modified to accept a pellet burner. The DRA 25 conveyor is included as part of the standard package. Additional components such as a fuel level indicator or a secondary conveyor may be required depending on the boiler's fuel delivery system. The tank is not compatible with boilers that use a different type of fuel or a different conveyor system. Installers should verify the boiler's specifications before selecting the appropriate tank and conveyor combination.

Technical background for designers

The AZPU tank operates by storing pellets in a sealed compartment and using the DRA 25 conveyor to transport the fuel to the boiler's burner. The conveyor is driven by a 25 W gearbox, which provides sufficient torque to move the pellets along the 1.7 m length of the conveyor. The tank is constructed from durable materials that resist corrosion and wear, ensuring a long service life in a variety of operating conditions. The design allows for easy integration into existing boiler systems, with minimal modifications required to the fuel delivery path. The efficiency of the system is influenced by the alignment of the conveyor, the condition of the gearbox, and the quality of the pellets being used.

Service and operation

Regular maintenance of the AZPU tank involves checking the conveyor for wear and ensuring that the gearbox is operating smoothly. The tank should be inspected for signs of corrosion or damage to the seams. The fuel level should be monitored to prevent overfilling, which can lead to spillage and reduced efficiency. The conveyor belt should be cleaned periodically to remove any residual dust or debris that could affect its performance. No specific service intervals are provided in the brief, but routine checks are recommended to ensure the system continues to operate reliably.

Frequently asked questions

Can the AZPU tank be used with a boiler that has a different conveyor system?
No, the tank is specifically designed for use with the DRA 25 conveyor and a 25 W gearbox. It is not compatible with other conveyor systems.

Is the tank suitable for outdoor installation?
No, the tank is intended for indoor use in a controlled environment. It should be installed in a dry, sheltered location to prevent damage from moisture or temperature extremes.

Can the tank be expanded to increase its capacity?
No, the tank is available in fixed capacities of 240 L and 400 L. There is no option to expand the tank's volume.

What is the maximum distance between the tank and the boiler?
The conveyor is 1.7 m in length, so the tank should be installed within this distance from the boiler to ensure proper fuel delivery.
