With the development of electric and electronic technology, resulting in power quality deteriorating caused serious pollution, power grid. According to the actual situation of ROSWELL power and industrial users, power quality monitoring, analysis of electric power and industrial users, and provide power system solution, to provide customers with innovative products that meet their needs, technology, services, and create long-term service and potential value for customers.
ROSWELL was formerly located in Bonn, founded in 1960, is part of the SAXE family. ROSWELL started to automation and control, twentieth Century 80 years in power quality compensation of wattless power industry, is the earliest safety, environmental compensation, depending on the design team to complete, to ensure the safety of the compensation scheme for each customer "tailored" the most reasonable, economy. Analysis of Ross vair dedicated to power quality and solutions, based on the non power compensation and harmonic control, to provide "tailored" is more suitable for the power quality solutions for each customer. Widely used in metallurgy, chemical industry, shipbuilding, building and so on various occasions, for the vast number of users of the production safety, energy conservation, improve power quality to provide a reliable guarantee.
Roswell (Wuxi) company is the German Ross vair Electric Co Ltd strategic partner, enjoy only authorized in China in mainland China and the Asia Pacific region, our goal is to service the Asia Pacific market. China will be the focus of ROSWELL's global growth, at the same time the company will be first-class technology and services to customers, through the first-class product quality, to realize his promise a full range of services and in synchronization with the world level advanced technology.
Technological innovation is one of the important factors of ROSWELL success. In the energy field, we are exploring new solutions, in response to the twenty-first Century global energy challenges.
Our solution is committed to quality and optimize energy use. Our products will create a more efficient, sustainable and competitive new energy model to make contribution, and achieve economic development and environmental protection, harmonious coexistence.
