Maxitrol MT1-57 Mixing Tube

The Maxitrol MT1-57 serves as a critical 57-inch mixing tube for dual sensor application within Selectra electronic gas flame modulation systems. Designed for professional HVACR technicians, this industrial discharge air sensor housing is engineered to stabilize the air stream for high-precision temperature monitoring. By facilitating the proper blending of gas and air before it reaches the TS114 or TS214 series sensors, the MT1-57 ensures consistent signal feedback to the Maxitrol amplifier. This prevents erratic flame behavior and short-cycling in high-capacity makeup air heaters and direct-fired burners. Built for durability in commercial environments, the 57-inch length is optimized for larger ductwork where deep penetration is required to achieve a representative air sample. Utilizing this OEM Maxitrol component maintains the integrity of the Series 14, Series 44, and Series 94 control loops, providing the steady-state performance necessary for tight climate control and process heating applications.

• Precise Signal Accuracy: Ensures the discharge air temperature sensor receives a uniform air sample, reducing modulating valve hunting.
• System Compatibility: Seamlessly integrates with Maxitrol Selectra Series 14, 20, 44, and 94 electronics for dual sensor configurations.
• Heavy-Duty Construction: The 57-inch rigid design is ideal for large-scale industrial HVAC ducting where standard tubes cannot reach.
• Fuel Versatility: Compatible with all common fuel gases used in direct-fired and indirect-fired heating processes.

Does the MT1-57 come with the sensor included?
No, the MT1-57 is the mixing tube housing only. Technicians must pair it with a compatible Maxitrol sensor such as the TS114 or TS214, ensuring the temperature range matches the remote selector.

Where should the mixing tube be installed for best results?
For optimal flame modulation, install the tube in the discharge air stream where it can sense a representative mix of air, avoiding "dead spots" or areas with excessive turbulence immediately following the burner.

Can I use this for both direct and indirect-fired systems?
Yes, the MT1-57 is a universal component for Selectra systems and is effective in both direct-fired makeup air units and industrial indirect-fired heaters.
