Runkel Electric Heating Technology Co., Ltd. specializes in the research, development, manufacture, sales, and technical service of industrial electric heating solutions. Building on the manufacturing heritage of Yangzhong Sanhuan Electric Heating Group, Runkel combines established production capability with fifteen years of independent innovation for customers in diverse industrial sectors.

The company’s product scope covers customized heating elements and assemblies, including flanged and boiler immersion heaters, duct and HVAC heaters, explosion-proof heating solutions, and electric heaters for environmental equipment such as RTO systems. Three strategic manufacturing bases in Shenyang, Shijiazhuang, and Yangzhong support project coordination and production for domestic and international customers.

Runkel’s approach begins with application data. Engineers consider the medium, temperature, pressure, flow, installation space, electrical supply, materials, hazardous-area requirements, controls, and maintenance needs before defining a solution. This process is especially important for high-power heaters and applications where corrosion, fouling, low flow, or extreme ambient temperature can influence performance.

The company operates an ISO 9001 quality management system and emphasizes customer-oriented innovation and responsible manufacturing. For a project discussion, customers can send process data and drawings to info@runkel.cn or contact the sales team through www.runkel.cn. All final technical parameters are confirmed against the specific operating conditions and project requirements.

Manufacturing capability is supported by process control and inspection. Depending on the product, production may include tube preparation, resistance-wire design, insulation filling and compaction, forming, welding, assembly, electrical testing, dimensional inspection, and final documentation. The exact inspection plan is agreed according to the heater type and project requirements.

Runkel works with equipment manufacturers, engineering companies, distributors, and industrial end users. OEM support can cover custom dimensions, electrical connections, markings, packaging, and repeat production based on approved drawings. Customers are encouraged to involve the engineering team early, particularly when a project combines high power, restricted space, corrosion, hazardous locations, or unusual control requirements.
