Import Defrost Heater — Buy in Bulk from Supplier in China

The defrost heater from Jiangyin Guanglilai Electric Appliance Co., Ltd is a tubular heating element designed for indirect-cooling refrigeration systems, with a typical power rating of 150 to 600 watts and operating voltage of 110V or 220V AC. It features a stainless steel sheath with magnesium oxide insulation, suitable for direct contact with evaporator coils in commercial and residential units. The heater is engineered to activate during defrost cycles, preventing ice accumulation that reduces heat transfer efficiency and increases compressor workload.

This heater is commonly used in systems requiring consistent thermal output, such as walk-in coolers, refrigerated display units, and HVAC air handlers. The standard length ranges from 150mm to 400mm, with termination options including insulated wire leads or screw terminals. The sheath thickness is typically 0.5mm to 0.8mm, and the maximum surface temperature under normal operation does not exceed 250°C. These characteristics align with standard industrial defrost heater specifications for refrigeration applications.

Buyers in the food storage, pharmaceutical cold chain, and HVAC maintenance sectors source this heater for retrofitting aging units or integrating into new equipment. Packaging is in bulk cartons of 50 to 100 units, with custom labeling available. Trade terms are typically FOB Shanghai or CIF port of destination. Minimum order quantities are flexible and confirmed per order. Lead time is generally 15 to 25 days after payment, subject to production schedule.
