MARS 33475 Commercial Refrigerator Thermostat Open 40°F Close 20°F

The MARS 33475 Commercial Refrigerator Thermostat works as a temperature controller that starts operation when the temperature reaches 40°F and ends operation when it reaches 20°F. This operates to preserve safe food temperatures inside commercial refrigerators and freezers. These thermostats operate through a process of temperature measurement followed by a set value comparison. The thermostat adjusts cooling operations to reduce the temperature difference from the set point. The temperature sensor enables control over the compressor start and stop times to achieve this function. Walk-in coolers and freezers together with refrigerated cases require these thermostats to manage airflow and stop temperature variations.
