Maxitrol MT2-12 Mixing Tube

The Maxitrol MT2-12 Mixing Tube is an essential 12-inch component engineered for high-precision gas sensor integration within the Selectra series modulation systems. Designed specifically for single sensor application, this duct sensor mixing tube facilitates accurate airflow sampling across the cross-section of the duct, ensuring the electronic gas modulation system receives consistent data for temperature control. This Selectra system accessory is critical for inlet air sensor configurations where turbulent air or temperature stratification might otherwise lead to hunting or inefficient burner operation. Field technicians rely on the MT2-12 for its 2x4 box size compatibility and robust construction, which stabilizes gas measurement in demanding commercial and industrial HVAC environments. When installing gas furnace control parts, using a properly sized mixing tube for Maxitrol ensures the discharge air temperature remains within the specified deadband, maximizing the efficiency of the combustion control loop.

Technical Benefits:

• Optimized Sampling: Provides a uniform gas sensor environment by averaging temperature and flow across its 12-inch profile.
• System Compatibility: Fully compatible with Maxitrol Selectra Series 14, 21, and 44 electronic modulation systems.
• Simplified Integration: Features a standard 2x4 box size to streamline duct sensor mounting in tight field conditions.
• Industrial Durability: Engineered to withstand high-velocity airflow without vibration or sampling degradation.

Common Questions:

How does the MT2-12 improve Maxitrol system accuracy?
The MT2-12 acts as a localized plenum, ensuring the thermistor or sensor is exposed to a representative sample of the air stream, eliminating erratic modulation caused by air layering.

Can this tube be used with dual sensor applications?
This specific model is optimized for a single sensor application. For dual sensor requirements, verify the specific sampling depth and sensor mounting points required for your controller.

Where is the ideal placement for this duct mixing tube?
It should be installed in a location with unobstructed airflow, typically downstream of the blower but upstream of any significant duct transitions to ensure reliable gas sensor readings.
