Maxitrol MT1-12 Mixing Tube

The Maxitrol MT1-12 is a professional-grade 12-inch mixing tube engineered for precise temperature control in Selectra Series 14 and 44 electronic gas modulation systems. Designed specifically for dual sensor applications, this component ensures a representative sample of air is delivered to the discharge air temperature sensor (such as the TS114 or TS194 series). By providing a stabilized environment for the sensors, the MT1-12 facilitates accurate signal feedback to the amplifier, maintaining consistent discharge air temperatures in direct and indirect-fired makeup air units or space heating applications.

This aluminum duct sensing housing is essential for contractors and technicians looking to optimize gas-fired system performance and prevent erratic burner modulation. The 12" length allows for proper penetration into the ductwork, ensuring that the sensor is not influenced by dead air pockets or localized turbulence near the duct walls. It is fully compatible with Maxitrol Selectra systems used in commercial environments like paint spray booths, door heaters, and industrial process heating where precise air velocity and temperature sensing are critical for operational stability.

• Dual Sensor Compatibility: Specifically designed to house two sensors for complex discharge air temperature control and limit sensing.
• High-Performance Mixing: Facilitates uniform air-to-gas mixture tracking for the Selectra modulation amplifier to prevent hunting and short-cycling.
• Rugged Construction: Built to withstand commercial HVAC environments and high-velocity airflow within duct sensing systems.
• Standardized Fit: 12-inch length provides the necessary depth for most standard commercial ductwork applications.
• Seamless Integration: Pairs directly with Maxitrol Series 14 and 44 amplifiers and modulating valves for a complete temperature control solution.

• What sensors are compatible with the MT1-12? This mixing tube is designed to work with Maxitrol TS series sensors, including the TS114, TS144, and TS194 variants used in makeup air and space heating.
• Where should the MT1-12 be installed? For accurate field sensing, it should be mounted several feet downstream of the heat exchanger or blower to ensure a fully mixed air stream.
• Can this be used for inlet air sensing? Yes, the MT1-12 is often utilized for inlet air sensors (like the TS10765) to provide inverse change logic in discharge air based on outdoor temperatures.
