Maxitrol MT1-9 Mixing Tube

The Maxitrol MT1-9 is a 9-inch mixing tube specifically engineered for dual sensor applications within Selectra gas modulation systems. As an essential component for high-precision thermal regulation, this mixing tube facilitates the integration of inlet air sensors and duct sensors, ensuring accurate temperature sampling in HVAC industrial heating environments. It is fully compatible with Maxitrol Series 14, Series 21, Series 31, and the robust Series 44 and 94 systems. By providing a dedicated enclosure for atmospheric sensing, the MT1-9 mixing tube allows the control system to calculate the necessary inverse change in discharge air for every degree of inlet temperature fluctuation. This structural assembly is critical for maintaining stable combustion and consistent discharge air temperatures in makeup air units and process heaters. Constructed for durability in demanding mechanical rooms, the 9-inch length offers a versatile profile for standard ductwork installations, optimizing the performance of Maxitrol modulating gas valves and secondary sensing circuits.

• System Compatibility: Seamlessly integrates with Series 44 System and Series 94 System for comprehensive modulating control.
• Dual Sensor Support: Designed specifically to house sensors for monitoring both inlet air and discharge air.
• Precision Sampling: Ensures the air-gas mixture is regulated based on live thermal data, preventing temperature "droop" in the system.
• Compact 9-Inch Profile: Ideal for tight duct sensor applications where 12-inch or longer tubes are not feasible.
• Industrial Build: Manufactured to withstand the high-cycle demands of commercial gas-fired furnaces and heaters.

Common Questions

Does the MT1-9 come with the temperature sensor included?
No, the MT1-9 is the physical mixing tube only. Sensors such as the TS194 or inlet air sensors must be purchased separately based on your specific Maxitrol Selectra series requirements.

Where should the mixing tube be installed for the best results?
For inlet air sensors, the tube should be mounted in a representative duct location upstream of the burner to provide accurate inverse temperature compensation for the modulating gas valve.

Can I use this with a Maxitrol Series 20 system?
Yes, the MT1-9 mixing tube is a standard accessory for Selectra series electronics that utilize dual-sensor 55°F to 90°F or high-temperature ranges for precise air modulation.
