What are Heating Cables and How Do They Work in Freezers and Coldrooms?
Heating cables are a type of electrical wire that is designed to emit heat. Because the product is flexible, it is simple to wrap the cables around objects to keep them warm. When used in freezers and Coldrooms, the product’s purpose becomes clearer.
Application in a Room
When we think about freezers, we think of one environment. A thermostat and a cooling unit lower the temperature. Ice develops, and we never consider the need for warmth. After all, this is supposed to be a frigid area. Subzero air, as intended, prevents taste-degrading biological activities by keeping the temperature cold, but freezers and Coldrooms also rely on technology and structural components that cannot withstand ice. Special flexible heating components, heating wires that operate as a low-grade but effective trace warming line, are used to solve the problem. They are installed on freezer doors to prevent ice from distorting or freezing the mechanism, and they are also used to protect pipes since they run parallel to water lines and prevent liquid water from freezing.
Prevents Floor Heave
If we were to go inside an old cooler and see how it has survived the decades, we would definitely be astonished, because the floor has suffered a terrible transformation. Concrete flooring does not respond well to subzero temperatures; thus some type of floor heating is required to avoid this messy structural issue. A properly fitted network of heating cables, going over every square meter of the floor, prevents the floor from freezing solid and the concrete from “heaving.” Keep in mind that a frozen floor will split and raise, opening up a new route for energy loss.
The cables are available in two variations: self-regulating and fixed resistance. Within the cable, two self-regulating conductors sandwich a particular conductive core that alters its conductivity as the temperature changes. Meanwhile, the purpose of the fixed resistance is self-explanatory in that it always supplies the same amount of heat.
When adding heating to freezers and coldrooms, an installation engineer examines the length of the run, the kind of heating wires, and a variety of other criteria.
