Structural Concepts 78657
DEFROST PROBE
SKU: STC78657
Condition: NEW
The defrost mechanism in a refrigerator heats the cooling element (evaporator coil) for a short period of time and melts the frost that has formed on it. The resulting water drains through a duct at the back of the unit. Defrosting is controlled by an electric or electronic timer: For every 6, 8, 10, 12 or 24 hours of compressor operation it turns on a defrost heater for 15 minutes to half an hour.
A defrost thermostat opens the heater circuit when the evaporator temperature rises above a preset temperature, 40°F (5°C) or more, thereby preventing excessive heating of the freezer compartment. The defrost timer is such that either the compressor or the defrost heater is on, but not both at the same time.
There are many types of probes used in restaurant equipment for the measurement of temperature, humidity, liquid level, ice level, product or ingredient levels and other critical operating limits and control points (HACCP). A probe is a small device, especially an electrode, used for measuring, testing, or sensing and obtaining information. Probes are commonly thin and oblong, and may be flexible. They provide data output to other components to control operation of the equipment.
