PD476604 | Defrost and Ambient Sensor Kit | Rheem-Ruud

Defrost and Ambient Sensor Kit: PD476604 by Rheem-Ruud The PD476604 Defrost and Ambient Sensor Kit is designed to monitor and control defrost cycles in refrigeration and HVAC systems. This kit combines two essential components: a defrost sensor and an ambient temperature sensor. The defrost sensor is a snap-disc thermostat that detects when the evaporator coil has reached a predetermined temperature, typically around 32°F (0°C). When the coil temperature drops below this setpoint, the defrost sensor signals the control system to initiate the defrost cycle. This prevents ice buildup on the coil, ensuring efficient heat transfer and maintaining system performance. The ambient temperature sensor measures the surrounding air temperature and provides input to the control system. This information helps the system determine the appropriate defrost termination temperature to prevent over-defrosting and energy waste. The PD476604 kit is essential for maintaining optimal system operation and energy efficiency in refrigeration and HVAC applications. Its reliable and accurate sensors ensure proper defrost cycles, reducing maintenance costs and extending the lifespan of equipment.
