1-Power and Efficiency:
It is designed to heat efficiently to facilitate defrosting operations on commercial refrigerators while using as little energy as possible. This wattage level is good for commercial refrigerators that typically require an optimal balance of power and efficiency.
2-Materials and Durability:
Its stainless steel (SUS) construction ensures superior durability against cold and moist environments with significantly reduced risks of corrosion and surface wear.
SUS is a known material for excellent thermal conductivity with the capacity to resist harsh environments when de-icing, which will perform more efficiently for a longer duration.
3-Defrost Mechanism:
The heater is typically located around or near the evaporator coils. The heater's purpose is to provide heat during the defrost cycle to melt ice/frost built up on the evaporator coils that will ensure the cooling system is efficient.
Regular defrosting is important for commercial refrigerators since frost can build up within the compartment and affect airflow through the refrigerator and cooling efficiency.
The SUS Defrost Heater is a popular solution used in many commercial refrigeration applications to minimize frost on evaporator coils and optimize cooling and temperature control. The following are some typical applications where the SUS Defrost Heater is ideal:
1.-Commercial Freezers & Refrigerators: These appliances are found mainly in supermarkets, restaurants, or convenience stores where frost blocks airflow and limits the efficiency of cooling systems can be important for these businesses.
2.-Cold Storage and Warehouses: In commercial refrigeration, large active or passive storage units need to maintain food or other products in temperatures for longer periods of time. Ice build-up can become quite expensive and result in unwanted temperature changes if there are excessive ice build-up.
3.-Pharmaceutical Refrigeration: The same principles that apply to food storage for cold storage for vaccines and medicines. They need to maintain consistent temperature range for storing vaccines, medicines etc.
4.-Beverage Coolers & Ice Makers: Open displays need to remain frost-free or visibility is limited. Ice makers need to continue to function. The SUS Defrost heaters are an ideal way to maintain optimized temperatures and also proper viewing conditions.
