United Electric SD6225-75 Brass Well
Professionals in the field rely on the United Electric SD6225-75 to provide a rigid, pressure-tight housing for temperature bulbs and capillaries. This brass thermowell is built for hydronic and process systems where maintaining a sealed boundary is critical during sensor maintenance. Featuring a 1/2" NPT process connection and a 4-inch immersion depth (4" BT), it ensures the sensor is positioned deep enough into the flow for accurate thermal transfer while shielding it from high-velocity pressures and corrosive system fluids.
When you are dealing with frequent cycling or high-pressure water services, the solid-bored brass construction offers consistent heat conductivity to the sensing element. This specific model is designed for United Electric 100 Series temperature switches and other remote-mounted bulb and capillary systems. The 1/2-inch NPT external thread simplifies HVAC sensor installation into standard tees or threadolets, allowing for sensor replacement without the need to drain the entire piping loop.
Key Benefits:
- Fluid Isolation: Facilitates sensor removal or service without system depressurization.
- Optimized Insertion: The 4-inch immersion length ensures accurate temperature readings by reaching the center of the flow.
- Robust Connectivity: Standard 1/2 NPT thread provides a secure, leak-free seal in industrial HVACR applications.
- High Thermal Conductivity: Industrial-grade brass material allows for rapid response times to temperature changes.
- Multi-System Compatibility: Engineered for use in boilers, chillers, and process plants.
Common Questions:
What type of sensor is this well compatible with?
The SD6225-75 is specifically designed for United Electric bulb-and-capillary temperature switches (Types E and F) and remote sensors that require a 1/2" NPT entry.
Can this be installed in a pipe smaller than 4 inches?
For pipes smaller than the 4-inch insertion depth, it is common practice to install the thermowell into a tee at an elbow configuration to ensure the tip is fully immersed without obstructing the flow.
Is this suitable for high-pressure steam?
While brass is excellent for hydronic and low-pressure applications, for high-pressure steam or highly corrosive environments, transitioning to a stainless steel (316 SS) well is often recommended for increased structural integrity.
