Danfoss AVTBWELL 3/4" Brass Thermowell for 0.7" Sensor

The Danfoss AVTBWELL is a brass thermowell designed to provide a protective housing for temperature sensors in HVAC and hydronic heating systems. This 3/4-inch NPT threaded well is specifically engineered to accommodate sensors with a 0.7-inch (17.8mm) diameter, ensuring secure mounting and accurate temperature readings.

Key Features:

• Durable brass construction for corrosion resistance and longevity
• 3/4-inch NPT thread for easy installation in standard pipe fittings
• Designed for 0.7-inch diameter temperature sensors
• Provides immersion protection for sensors in liquid-filled systems
• Compatible with Danfoss temperature sensors and controls

Thermowells are essential components in heating and cooling systems, allowing sensors to be inserted into the flow stream while protecting them from direct contact with the medium, turbulence, and pressure. This enables sensor replacement without system shutdown and extends sensor life. The AVTBWELL is commonly used in boiler applications, chilled water systems, and hydronic heating circuits where accurate temperature monitoring is critical for system efficiency and control.
