Identity and regional scope
河南三元光电科技有限公司（三元光电／圆圆圆品牌线索）. Website-described electric-heating and cooking-equipment supplier; this record is limited to its commercial kitchen and infrared-grilling offers, not all household-heating or energy-storage products.
Published location: Sanyuan far-infrared electronic/electrical industrial park, Guandu River industrial cluster, Guangshan County, Xinyang, Henan, China; company-published contact location. This is a supplier-published address, not proof of factory ownership. English labels and Chinese source wording should be checked against the contracting documents.
Published food machinery scope
The independent desktop and mobile sites explicitly offer commercial cooking and infrared barbecue equipment; the mobile catalogue shows large-wok cooking units. The owned contact page locates the business in Guangshan's Guandu River industrial cluster. SANRA/Sanyuan and the Yuanyuanyuan brand clue remain one attributed supplier record, not multiple manufacturers or a connection to similarly named machinery companies. Claimed zero-carbon operation, health benefits, energy savings, patents, factory scale, staff numbers, certificates and sales totals are not adopted.
