Johnson Controls WZ-1000-4 Well

The Johnson Controls WZ-1000-4 is a professional-grade immersion well engineered for precision temperature monitoring in hydronic and pneumatic control systems. Constructed from 304 stainless steel, this bulb well provides superior corrosion resistance and structural integrity in demanding HVACR environments. Featuring a 1/2-inch inside diameter (ID) and 1/2-14 NPT external threading, it ensures a secure, leak-proof thermowell installation. This component is rated for high-pressure applications up to 400 psi and can withstand operating temperatures reaching 600°F, making it a critical asset for HVAC temperature sensor protection. Designed for industrial refrigeration and commercial boiler systems, the WZ-1000-4 facilitates accurate thermal transfer without direct probe exposure to the medium. This well is compatible with a variety of Johnson Controls sensors and bulb-type controllers, allowing for seamless integration into existing building automation architectures. Its 5-1/4 inch length and robust stainless steel connector and tube assembly provide the reliability required for long-term system performance and maintenance-free operation.

Common Questions

Does this well require thermal conductive compound?
While the WZ-1000-4 is supplied without thermal compound, applying a high-quality conductive paste inside the well is recommended to improve response time and sensing accuracy.

Is the WZ-1000-4 compatible with non-Johnson Controls sensors?
Yes, provided the sensor probe has a diameter smaller than the 1/2-inch ID and the insertion length is compatible with the 5-1/4 inch well depth.

Can this thermowell be used in outdoor installations?
Its 304 stainless steel build is highly resistant to environmental factors, making it suitable for outdoor exposure when properly sealed at the conduit or sensor entrance.
