Law Chain Computer Technology was founded in 1993. At the beginning we concentrated on PC selling and computer software design. In 1996, with PhDs in electrical engineering and computer science joined us, we set up R&D department and went into automation system development. At the beginning, the products we developed included temperature controllers, remote controllers and stage effect controllers etc., but turned out to be not very successful due to the lack of experience. Therefore, we decided to concentrate on a single area of automation in order to accumulate our experience and knowledge, and expected to produce more stable and high quality products to conform industry needs. Now, we have various series of high quality products, which can be seen in the market for years, including Refrigeration Controllers, Liquid Chiller Controllers, High Temperature Water Dispenser Controllers. Besides the quality of products, the quality of customer services is another major concern to us. We have been making great efforts to help our customers to solve the problem they met and we hope all our customers will be satisfied with our products and service.
