A: Chuanli cold room electric defrost tube is mainly used for evaporator defrosting of cold storage, walk-in freezer, commercial freezer and refrigeration equipment. It is the core heating component for electric defrost system of cold room air cooler. In low-temperature cold room, water vapor will condensate and form thick frost layer on evaporator fin surface. Thick frost will block air flow, reduce heat exchange efficiency, increase compressor load and waste energy. The electric defrost tube is installed on evaporator coil, when defrost cycle starts, the tube generates heat to melt frost and ice layer on fins, melted water flows out through drain pan and drain pipe. After defrost finished, refrigeration system restarts and continues cooling. This electric defrost method is simple, stable and widely adopted in medium and small cold storage, food preservation cold room, meat freezer, supermarket refrigeration cabinet and ice maker. Different cold room types have different defrost power requirement. Large industrial cold room evaporator needs higher power defrost tubes; small commercial cold room uses low power heating tubes. Our technical team can assist model selection according to your cold room volume, evaporator size, working temperature and defrost cycle setting. We have many reference project cases for cold room engineering contractors. If you are refrigeration equipment manufacturer, we can design matched defrost tube for your evaporator product.
