For commercial kitchen equipment, a temperature control is a safety component as much as a functional one. It switches heating circuits on and off all day, every day — and a safety temperature limiter is the last line of protection if a control fails. That is why our thermostats are tested and certified by TÜV Rheinland, an independent testing and certification body.
The certificates below are held by Guangzhou V.Crown Thermostat Co., Ltd., the manufacturer established in 1995 behind the HengTherm brand — HengTherm is the export brand of Guangzhou V.Crown Thermostat Co., Ltd. Certified production is subject to ongoing surveillance by TÜV Rheinland, as stated on each certificate. We publish the original certificate documents here, unmodified, so that buyers, importers and equipment manufacturers can check them directly before they specify our controls.
