Belimo A-22P-A09 Thermowell

The Belimo A-22P-A09 is a high-performance fabricated stainless steel thermowell engineered for precise temperature sensing in hydronic systems. Designed for field technicians who prioritize durability and accuracy, this 6-inch immersion sleeve features a 1/2" NPT external thread for seamless integration into standard pipe fittings. Its construction utilizes AISI 316L for the thread and hex components, while the immersion length is crafted from AISI 316Ti, providing superior resistance to corrosion and pitting in water-based applications. The integrated compression fitting simplifies the installation of 01DT, 22DT, 01CT, and 22CT immersion sensors, ensuring a secure and thermal-conductive fit. With a maximum allowable pressure of 580 psi (40 bar) and a temperature threshold up to 392°F (200°C), this thermowell maintains structural integrity under significant flow velocities. Whether used in chilled water or high-temperature heating loops, the A-22P-A09 offers the mechanical protection needed to extend the service life of sensitive sensor elements without compromising response times.

• Corrosion Resistance: Fabricated from 316 stainless steel to ensure long-term reliability in aggressive hydronic environments.
• High Pressure Rating: Rated for up to 580 psi, making it suitable for high-rise commercial HVAC piping systems.
• Standard Compatibility: Features a universal 1/2 inch NPT connection, allowing for easy Retrofitting or new installations.
• Optimized Insertion: A 6-inch immersion length ensures the sensor tip reaches the center of the flow stream for the most accurate readings.
• Integrated Compression: Includes an internal polyamid fitting that secures the immersion sensors without the need for additional hardware.

What is the maximum flow velocity for the A-22P-A09?
This 6-inch Belimo thermowell is rated for a maximum flow velocity of approximately 28.5 ft/s (8.7 m/s) to prevent mechanical vibration and fatigue.

Which Belimo sensors are compatible with this pocket?
The unit is designed specifically for Belimo immersion sensors, including the 01DT, 22DT, 01CT, and 22CT series with various passive and active outputs.

Can this be used in steam applications?
While the 316 stainless steel construction handles up to 392°F, it is primarily optimized for water and water-glycol mixtures in industrial HVAC applications.
