[9] Their product line includes immersion heaters for liquids and gases, hot air heaters for drying processes, induction heaters for rollers, and custom molding heaters made from aluminum, cast iron, or brass. The company emphasizes high thermal efficiency and product longevity. [9]

3. Korea Heating Co., Ltd.

This company specializes in far-infrared heating film, a modern application of Korea’s traditional “Ondol” underfloor heating concept. [24, 40] Marketed as ‘Hot-Film,’ their products are used in architectural underfloor heating systems. Korea Heating Co., Ltd. has a strong export focus, supplying its high-tech heating materials to over twenty countries, promoting the efficiency and health benefits of the Ondol system globally. [24]

4. Bosung Industry Co., Ltd.

Since 2003, Bosung Industry has been manufacturing and distributing electric heating products based entirely on domestic technology. [28] Their main products include electric convectors and far-infrared radiant heaters for ceiling installation. The company holds multiple patents and manages its production under an ISO 9001 quality system, with a production capacity of 10,000-20,000 units per month. [28]

The Role of International and OEM/ODM Suppliers

The South Korean market is not isolated. Many domestic manufacturers rely on a global supply chain for raw materials and specialized components. Furthermore, major international players have a direct presence. For instance, Watlow, a global leader in thermal solutions, operates a sales and engineering facility in Seoul to serve the high-tech semiconductor and electronics industries directly. [14, 44]

Beyond direct sales, many Korean brands partner with specialized overseas manufacturers for component development and production. An established Electric heating element factory with extensive experience can offer significant advantages. For example, Jinzhong Electric Heating Technology, with over 30 years in the industry, provides full-chain capabilities from design and mold development to precision manufacturing. This one-stop manufacturing chain, which integrates processes like die-casting and CNC processing, allows for shortened delivery cycles and scaled production capacity, reaching up to 3 million heating elements per month. Such capabilities are essential for global brands like Philips, Midea, and Delonghi, who require stable, high-quality, and certified components (ISO, VDE, UL, RoHS) for their products.
