HANZEL Electric (Yixing) Co., Ltd.
About
HANZEL Electric, operating under Hengsu Holdings Co., Ltd., is a Chinese electric motor manufacturer founded in 1991 with headquarters in the coastal industrial zone of Taizhou, Zhejiang Province. The company operates five subsidiaries and three manufacturing plants with over 500 employees, serving customers in more than 50 countries with a comprehensive induction motor range spanning 0.09 kW to 1,000 kW across efficiency classes IE1 through IE5. The YDT series is specifically engineered for pump and fan duty, making it the primary product line for water and wastewater treatment applications where motors drive pumps, blowers, and aeration equipment. HANZEL's explosion-proof motor lines — YB3, YBX4, YBX5, and YBBP5 — address hazardous environments common in biogas plants and sewage treatment facilities where flammable gases may be present. The YVF2 variable frequency series enables energy-efficient speed control for pump flow modulation, while the YD multi-speed motors provide dual-speed operation without requiring VFDs. Complementing the motor lineup, HANZEL produces permanent magnet synchronous motors (YXTY and STB series), electromagnetic brake motors (YEJ2), high-temperature duty motors, fan motors (YT3/YSF3), compressor motors (ZYS), vibration motors, and inverters. The company also manufactures worm gear, gear, and speed reducers for mixer, agitator, and screw press applications, plus electric blowers explicitly rated for wastewater treatment and sewage treatment aeration. All products are manufactured to IEC 60034 standards.
