Since 1931 Walther Trowal has been developing and producing systems for the refinement of surfaces. Initially focusing exclusively on mass finishing – the term “Trowalizing” originated from the company’s cable address “Trommel Walther” – Walther Trowal has continuously expanded its product portfolio.
Over time the company has developed a broad range of machinery and systems for mass finishing, shot blasting and coating of mass produced small components.
With the invention of new systems like, for example, drag finishing and the development of special finishing methods for 3D printed components, the company has proven its innovative capabilities again and again.
Trowal develops and implements complete surface treatment solutions that can be seamlessly integrated into linked production systems existing at the customers. This includes the entire process technology, perfectly adapted to the specific surface finishing requirements of the work pieces: Equipment and the respective consumables always complement each other in a perfect manner.
Each individual work piece and each manufacturing process must meet special technical requirements. That is why the experienced process engineers in our test lab, in close cooperation with the customers, develop the optimal process technology for the finishing task at hand. The result: Work piece surfaces that meet exactly the required specification with short processing times and a high degree of consistent, repeatable results.

We, Termokar Family, are about to leave a quarter of a century together. In this process, we worked together with our employees to innovation, argument and continuous education. Since the day we were founded, we have tried to bring the “Unconditional Customer Satisfaction” slogan to the top.

BITEMAN technology co., LTD was established in June 2006,the biggest and the best well-known Modular desiccant air dryer in China.BITEMAN successfully develop Modular and Modular-units desiccant air dryer,high precision compressed air filter and other products, has won 51 patents of domestic and international,the technology in this field to become the world's few with independent intellectual property rights and proprietary technology equipment manufacturers.General manager Mr Guo should glow in the ninth session of Chinese scientists in the BBS was awarded the honorary title of "star of science and technology" (2012).BITEMAN technology products have been as shenzhen advanced technology products in shenzhen industrial achievements exhibition exhibited abroad.
BITEMAN technology has always been adhering to the "let China become a manufacturing powerhouse is no longer a dream" of the enterprise vision, leading the technology revolution in the field of special compressed air purification. Through ten years of efforts and innovation, and formed a series of leading core technology system, which developed into, the buffer cavity shunt technology, many modules convection adsorption and regeneration technology,desiccant cartridge independent removable replacement technology, buffer chamber inlet heat exchange cooling technology, instantaneous discharge technology;Filter element Bottom-open technology, integrated drainage technology with zero air loss.
Over the years, BITEMAN for its excellent treatment effect, low energy consumption ratio,new Modular-units dryer achieve only 2% to 5% purge air loss,constant PDP -20 deg.C to -70 deg C,now BITEMAN become the biggest supplier of Modular air dryer in China,we are confident that for its huge energy saving ,it will be more popular in global world.
