The ultimate development direction of the second supply equipment is intelligent. The current frequency conversion constant pressure water supply equipment still adopts the traditional technical solution, which has the problems of low digitization degree, low generalization degree and low intelligence degree. In view of these, Kaiquan has developed the fifth generationofPLUS water supply equipment with the accumulation of more than 20 years of engineering experience in the water supply industry and a number of innovative leading technologies. The product not only completely solves the aforementioned problems, but also realizes the four full design of the two supply equipment for the first time in the industry: full parameter detection, full digital control, full frequency integration, and full intelligent control.
