The stainless steel coil heat exchanger unit is made of 304/316L food grade or industrial grade stainless steel, formed by precision winding and welding process, and the surface is polished, passivated or nano-coated. It is resistant to high temperature (80℃–500℃), high pressure (100kPa–500kPa) and corrosion. The spiral structure optimizes the heat conduction efficiency, integrates the PID temperature control module and thick film resistance heating element, supports power (500W–5000W) customization, realizes fast and uniform heating (3 seconds to 200℃), has anti-dry burning, overheating power off and self-cleaning functions, complies with the EU CE certification, has a service life of more than 30,000 hours, and is suitable for high-frequency industrial and civil heat exchange scenarios.

Our Coil Unit Heat Exchanger is a core component in the heating systems of electric kettles and water heaters, consisting of a coiled tube assembly designed to transfer heat efficiently. It converts electrical energy into thermal energy via resistance heating, evenly distributing heat to water or fluids, ensuring rapid and uniform heating performance while maintaining durability under repeated high-temperature operation.
Market-standard coil unit heat exchangers prioritize material safety (e.g., 304/316 stainless steel for water contact), high thermal efficiency, and corrosion resistance. Our factory utilizes: 304/316 stainless steel compliant with GB 4806.9 (food-grade material standards); precision coiling and welding processes to minimize heat loss and ensure structural integrity; and products certified to CE and RoHS for electrical and food safety. Customization for coil diameter, tube thickness, length, or interface designs (e.g., connections to heating elements or water inlets/outlets) is supported to fit specific appliance models.
