Coil unit heat exchanger

1. Product Application Overview

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.

2. Product Features (Market-Aligned & Factory-Based)

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.
