Laizhou Hongli Electric Heating Equipment Co., Ltd. is a high-tech enterprise with a professional technology research and development center. It has successively passed the "Winter Spring" trademark registration, Shandong Province scientific achievement appraisal, ISO9001 certification, National Compulsory Product Certification (CCC), utility model patent certification, etc. Hongli Electric has been developing and producing a series of "PTC" ceramic semiconductor thermosensitive materials since 1989. Including: PTC aluminum corrugated heater, hallway self extinguishing switch, and car low-temperature starter. On the basis of adding heating to electric fans, we have further utilized our existing production experience and technical conditions to manufacture the patented product "Liquid Pipeline Heater" (patent number: ZL98243786.2), which provides specialized core heating devices for production plants such as electric boilers, electric water heaters, showers, and water boilers, especially suitable for flammable liquids and petroleum pipeline heaters. Hongli Electric is committed to developing the "intelligent electric heating" technology industry, introducing the high standard service and corporate culture concept of home appliances into the HVAC industry. The intelligent electric boiler heating system is the result of the research, development, and industrialization of this technology. This system is a high-tech heating product that uses PTC semiconductor heating elements and special alloy aluminum plasma spraying technology to achieve heating purposes through circulating hot water conduction. The intelligent heating furnace adopts PTC heating method, which is characterized by water and electricity separation, safety and reliability, fast heating speed, high electric thermal conversion efficiency, and long service life. So far, there have been users who have used the intelligent electric boilers produced by our company with a service life of over 15 years The new type of semiconductor "PTC" uses ceramics as heating elements, with a Curie point temperature below 260 ℃, which is not afraid of dry burning. It cuts off power at high temperatures, and its power continuously decreases with increasing temperature, resulting in significant energy-saving effects. Our company's "PTC" liquid pipeline heater is currently cooperating with over thirty domestic and foreign OEM manufacturers to develop and produce various types and specifications of intelligent wall mounted heating electric boilers, intelligent floor mounted heating electric boilers, automatic electric heating boilers, manual electric heating boilers, and more. Our aim is: reasonable price, guaranteed quality, integrity-based, thoughtful service, and striving to create a famous brand. For many years, the product has been popular both domestically and internationally, and has been well received by users. Our company provides OEM cooperation services for electric boilers, electric heating furnaces, and instant electric water heaters. We welcome domestic and foreign customers to visit our company for inspection. Main products: electric boilers, household electric boilers, heating electric boilers, electric heating boilers, household electric heating boilers, wall mounted electric heating boilers and other products.
