CP25KS Set for ATMOS A 25 Burner

Product detailed description

Pellet-fired boilers require regular cleaning to maintain efficiency and prevent damage from clinkers and ash buildup. The CP25KS set is specifically designed for ATMOS A 25 and A 45 burners, which are commonly used in residential and commercial heating systems. Installers working with these models will benefit from the system's pneumatic cleaning function, which ensures rapid and reliable removal of combustion residues. This is particularly important when using lower-quality pellets that contain higher levels of impurities and bark. The system operates automatically, either at regular intervals or after each burnout cycle, reducing manual maintenance and improving system reliability.

Installers should consider the CP25KS set for boilers where frequent cleaning is necessary due to fuel quality or operational conditions. The system is compatible with a range of boiler models, including D 20 P, DCxxSP(X), CxxSP (with A 25 burner), D 30 P, D 31 P, D 40 P, and D 50 P (with A 45 burner). It is not required for the A 85 burner, which already includes pneumatic cleaning as standard. The set is intended for retrofitting and must be installed according to the manufacturer's specifications to ensure proper function and safety.

Technical parameters

Compressor	1500 W
Weight	32.2 kg
Code	H0524
Brand	Atmos

The 1500 W compressor provides sufficient power for effective cleaning of the combustion chamber. The 6 L air tank ensures stable operation during cleaning cycles. These parameters are essential for determining the system's suitability for specific boiler models and operational conditions. The compressor must be connected to a dedicated electrical supply, and the air tank must be properly mounted to avoid vibration or misalignment during operation.

Installation and connection

The installation process involves connecting the 1 m air hose (DN 28 mm) with a 3/4" coupling to the burner's cleaning system. The control solenoid valve must be wired to the boiler's control system, and the new combustion chamber and ignition coil bracket must be fitted. Installers should verify that all components are correctly aligned and that the air hose is securely fastened to prevent leaks. Common installation errors include incorrect wiring of the solenoid valve and improper mounting of the air tank, which can affect system performance and safety. It is also important to ensure that the AD02 control module is correctly configured to manage the compressor and solenoid valve according to the boiler's operating cycle.

Compatibility and accessories

The CP25KS set is compatible with ATMOS A 25 and A 45 burners used in a variety of boiler models. It is not suitable for the A 85 burner, which already includes pneumatic cleaning. For users who wish to disable cleaning during nighttime operation, a special timer must be purchased separately. This timer is not compatible with standard commercial models and must be sourced from the manufacturer. No additional accessories are included in the set, so installers should confirm that all required components are present before beginning installation.

Technical background for designers

The system operates by using compressed air to dislodge clinkers and ash from the combustion chamber. The 1500 W compressor generates sufficient pressure to clean the chamber effectively without damaging internal components. The combustion chamber and ignition coil bracket are constructed from durable materials to withstand high temperatures and repeated cleaning cycles. The AD02 control module ensures that the compressor and solenoid valve are activated at the correct intervals, based on the boiler's operating cycle. Proper integration into the boiler's control system is essential for reliable operation. The system's efficiency and service life depend on the quality of the installation and the regularity of maintenance checks.

Service and operation

The system requires periodic inspection of the air hose, solenoid valve, and compressor for signs of wear or damage. The air tank should be checked for leaks and cleaned as necessary. No specific service intervals are provided, but installers should follow the manufacturer's guidelines for routine maintenance. If the system fails to operate correctly, the control module and electrical connections should be checked for faults. The solenoid valve and air hose should also be inspected for blockages or leaks that could affect cleaning performance.

Frequently asked questions

Can the CP25KS set be used with the ATMOS A 85 burner?
No, the A 85 burner already includes pneumatic cleaning as standard. The CP25KS set is only suitable for A 25 and A 45 burners.

Is it possible to use a standard timer to disable cleaning at night?
No, a special timer must be used. Standard commercial timers are not compatible with the system's control module.

Can the system be retrofitted to older boiler models?
Yes, the set is designed for retrofitting. However, it is only compatible with models that use the A 25 or A 45 burners.

What should be checked if the system fails to clean the combustion chamber?
Check the air hose for leaks, the solenoid valve for blockages, and the control module for faults. Also verify that the compressor is receiving power and operating correctly.
