Utica-Dunkirk 240007709 Well
The Utica-Dunkirk 240007709 Temperature Well is an essential OEM replacement component designed for hydronic heating applications where high-accuracy thermal sensing is critical. This 3/4-inch NPT immersion well is precision-engineered to accommodate various temperature sensors and aquastat probes, ensuring a direct interface with the boiler water while maintaining a high-pressure seal. Unlike universal alternatives, this Hydrolevel temperature well (cross-referenced as 48-201) and PWXL assembly is built specifically for the ECR International family, ensuring perfect compatibility with Utica and Dunkirk boiler systems.
For a contractor in the field, response time and sensor accuracy are the primary performance metrics. The 240007709 well assy utilizes high-conductivity materials to maximize thermal transfer from the medium to the internal bulb or NTC sensor. This eliminates the measurement lag that can lead to inefficient cycling or safety limit delays. This robust HVAC replacement part is built to withstand domestic hot water and heating loop pressures, providing a long-term solution for localized temperature monitoring and aquastat housing during routine maintenance or full system overhauls.
Key Benefits
- Direct OEM Compatibility: Engineered specifically as a drop-in replacement for Utica-Dunkirk boiler parts, ensuring no thread mating or fitment issues.
- Optimized Thermal Transfer: Precision design minimizes measurement errors by allowing for efficient heat conduction to the boiler temperature sensor.
- Standard 3/4" Threading: Features a standard 3/4-inch NPT connection for easy integration into existing boiler tapped ports.
- Hydrolevel Engineering: Manufactured to match Hydrolevel 48-201 specifications for reliable high-limit and operating control logic.
- Durable Construction: Built to endure the high-temperature and high-pressure environments of industrial and residential HVAC systems.
Common Questions
Does this part include the temperature sensor or wire lead?
No, the 240007709 is the temperature well assembly only. It is designed to house a separate probe or sensor. If you require the sensor with the plug or wire leads, verify your boiler’s model and serial number to find the corresponding electronic component.
Is this well compatible with other brands besides Utica and Dunkirk?
While the 3/4" NPT threads are standard, this assembly is specifically spec'd for ECR International brands (Utica, Dunkirk, Pennco). Using this as a replacement immersion well on other brands should be verified by comparing the internal diameter and depth requirements of your specific aquastat probe.
What is the primary function of this immersion well?
This PwxL well assembly allows for the installation of a temperature probe into a liquid-filled system without requiring the system to be drained for every sensor replacement. It protects the sensor from the corrosive elements of the system fluid while providing a reliable thermal path.
