The SUS Defrost Heater is designed to melt frost on the evaporator coils without affecting the internal temperature where products are stored. Here's how it accomplishes this:
Targeted Heating on the Evaporator Coils
The defrost heater is installed directly around or near the evaporator coils, so its heat is concentrated only in this specific area. This targeted design focuses the heat where frost forms, leaving the surrounding refrigerated space and stored products unaffected.
Short, Controlled Defrost Cycles
The defrost heater operates in brief, timed cycles, just long enough to melt frost but not long enough to impact the refrigerator's internal temperature. Once the frost has melted, the heater shuts off automatically, limiting heat exposure within the unit.
Efficient Drainage of Melted Frost
Melted frost drains quickly through a designated system, preventing any remaining water from refreezing or pooling in the refrigerator. By efficiently removing melted frost, the heater keeps cold air circulating normally and minimizes any temperature shift.
Through these focused, brief defrost cycles, the SUS Defrost Heater removes frost buildup on the coils without warming the stored items, ensuring product safety and consistent cooling.
