Significantly different from secondary pressurization water supply equipment through pools, the pipe network superimposed water supply equipment has two obvious advantages: health and safety, low energy consumption. The Company started to design and produce superimposed water supply equipment since 2001and has developed three generations of products as divided per performance:
Non-vacuum products of the first generation:
Still being the mainstream (standard) products in the market, they feature the buffer and compensation of “steady flow tank ”that can effectively absorb pressure impacts from pump On/Off and sudden quantity change. The products are suitable for adequate water supply capacity of the region though their ability to compensate is limited,
Non-vacuum products of the second generation:
They are high-performance products, characterized by a greater compensation capability divided into minutes level (tank) and hour -level (box), to buffer or clip peaks of designed second quantity or maximum hourly quantity so as to avoid excessive suction from municipal pipe network.
Non-vacuum products of the third generation:
They are energy efficient products, characterized by a low-cost solution to the low efficiency and high energy consumption problems associated with small and medium quantity. That saves overall energy by 10%-20%. A number of patents have been applied for since the start of development in 2005. In addition, the third generation inherit high performance from the second generation

Domestic, building water supply
1.Efficient energy and low operating costs: They can take advantage of the inherent pressure potential of municipal water pressure before compensating the difference and effectively
saving energy through frequency change and speed control.
2.Health and Safety: They provide continuous sealed pressurized water supply that maintains the municipal water up to health standards for water quality and avoid reduced water quality and water pollution problems resulting from pressurization system.
3.Low operation noise: especially under high pressure of municipal pipe network at night, the device is under low-speed low-noise operating conditions.
4.Low equipment cost: It needs no pool, takes up little floor space, consumes little energy and operates at low costs.
5.The most common solution of water supply frequency control technology with a high degree of standardization is adopted to guarantee lifelong after-sale service.
6.Control of outlet variable pressure (terminal constant pressure) is adopted so that device is more energy efficient and more comfortable.
7.The perfect dual pressure control technology is employed to solve a series of problems caused by superimposed water supply.
