Marvair 70369 Sensor
The Marvair 70369 Freeze Stat Sensor is a critical NTC 10k ohm thermistor designed for precision monitoring in wall-mounted HVAC systems. Engineered to detect evaporator coil temperatures ranging from -40°F to 70°F, this OEM freeze thermostat sensor integrates directly with control boards like the Marvair 70281 to prevent compressor damage during low-ambient operation. By providing real-time data to the system controller, it triggers a shutdown if the coil temperature drops below the icing threshold, maintaining proper airflow and operational efficiency in telecom shelters, schools, and industrial enclosures.
This HVAC freeze protection sensor features a rapid response time and a compact, durable probe assembly for easy installation in high-moisture environments. Whether you are performing a freeze stat replacement or maintaining a standard unit with desert duty or low-ambient cooling packages, the 70369 ensures accurate temperature sensing without the risk of nuisance tripping or system icing. Its rugged construction is built to withstand the thermal cycling typical of commercial refrigeration and sensitive equipment cooling applications.
Key Benefits- Precise Coil Protection: Monitors the evaporator to prevent ice buildup and protect the compressor from liquid slugging.
- Wide Operating Range: Accurate sensing from -40°F to 70°F ensures reliability in diverse environmental conditions.
- OEM Compatibility: Designed as a direct drop-in for Marvair and Airxcel wall-mount units, ensuring seamless communication with the logic board.
- Industrial Durability: Built for critical infrastructure cooling, where uptime in telecom and server rooms is a priority.
What is the resistance value of the Marvair 70369?
This is a standard 10k ohm NTC (Negative Temperature Coefficient) sensor, where resistance decreases as the temperature rises.
Will this sensor prevent my evaporator coil from freezing?
Yes, when correctly positioned on the return or suction side of the coil, it signals the controller to cycle the compressor off if temperatures reach the freezing point.
Is the 70369 compatible with other control boards?
While primarily used with Marvair 70281 boards, it is compatible with any HVAC controller calibrated for a 10k NTC thermistor input.
Disclaimer: While we strive for 100% accuracy, product data and specifications are subject to change. Please contact our team to confirm compatibility or technical details before purchasing.
