B-Tohin Machine (Jiangsu) Co., Ltd., a foreign-funded enterprise established in 1994,is located in the Industrial Park for Environmental Science and Technology ,Yixing ,China. B-Tohin is mainly engage in the production and sales of roots blowers,rotary blowers,single-stage high-speed centrifugal blowers,multi-stage centrifugal blowers,air foil bearing centrifugal blowers,magnetic suspension centrifugal blowers,FRP fans,vacuum pump sand water pumps,and in the sales of Japan ShinMaywa water pumps.The products are sold all over the country and exported to many countries and regions for application in environmental water treatment building,materials and cement, chemical industry ,electric power,petroleum,steel,metallurgy,mining,printing and dyeing,grain transportation ,new energy ,new materials and other industries.Now the company has formed an annual production and sales scale of more than 30000 sets of blowers and water pumps.

The company has passed the ISO9001 quality management system certification,ISO 1400 environmental management system certification ,ISO45001 occupational health and safety management system certification and the “five-star”certification of national standard GB/T27922-2011 “Commodity After-sale Service Evaluation System” and it was named as “Specialized ,Refine, Characteristic and Innovative Enterprise of Jiangsu Provinces “,also was recognized as the “Enterprise in Compliance with the Standard Conditions for Environmental Protection Equipment Manufacturing Industry in 2002 (Announcement No.28 of the Ministry of Information Technology of the People’s Republic of China in 2001).

B-Tohin Machine (Jiangsu) Co., Ltd. is a foreign invested enterprise established in 1994. It is located at Yixing Industrial Park for Environmental Science & Technology, one of State High-Technology Development Zones. With total registered capital of RMB 120 million and total investment of RMB 160 million B-Tohin is engaged in production and sales of HC blower, BK and YU Roots blowers,air compressor blower,screw blower, anti-corrosion and anti-explosion stainless steel Roots blowers, gear speed-up centrifugal blower, multi-stage centrifugal blowers and in the sales of other supporting products for water treatment in environmental protection, such as water pump (YU, WQ submersible pump, YYOW split case pump), mixer, dewatering machine, etc. By the purchase of a new building of 26000 m2 area in Yixing Economic Development Zone in 2015, the expansion of production scale is supported.

B-Tohin’s products have been widely used in various industries, including water treatment, construction material and cement manufacture, chemical industry, electricity, petroleum, steel, metallurgy, mine, food convey lines, etc., enjoying a good reputation among customers both in the overseas and domestic market.

In the company’s Research and Development Center, a technical innovation team composed of professor level Senior Engineers, Doctors, Masters and many undergraduates, is aiming at the service for environmental protection by tracing and developing the products of high level.

B-Tohin has made great investment in introducing CNC, full-automatic digital control lathes, CMM and other advanced equipment to ensure good quality. A complete set of advanced horizontal OKUMA CNC was introduced specially for the fine finish machining of blower cylinders and end-covers; a NC machine was imported for the processing of blower parts; a Taiwan Dahlih-made CNC was equipped for machining the parts of middle and large size blowers; and several back-forth curve machining planers were introduced for solving the problem of shapers’ precision problem. This kind of planer ranks among the advanced level in China which is specially designed for curve machining of blower rotors. In the beginning of 2015, we cooperated with Testing Laboratory of Shenyang Blower Research Institute (Quality Supervision & Inspection Center for Blowers of China Machinery Industry), and a whole set of blower performance test system was designed for us according to the Roots Blower Industry Standard by the Laboratory.

Passed the certification of ISO9001 & ISO 14001:2400, the company has been nominated as “High & New-tech Enterprises of Jiangsu Province” and “Pneumatic Technology Research Center of Jiangsu Province”.
