No negative pressure water supply pipe network layers Product Overview: Series with the device directly to the water pipes, using the steady flow compensator and vacuum compensation system, microcomputer control, automatically adjust to incoming water pipes without negative pressure (no suction distance). So, using the device, the user does not affect the surrounding water. Features: Energy efficient: Due to use of computer-controlled frequency of new technologies, to take full advantage of existing pressure pipeline network, equipment, motor pump speed operation mode, only the water pressure and the pressure required to make up the difference between the pressure, in the Low water peak, water pressure of water to meet the requirements of the user, the device does not work, no electricity, running water directly from the water, and therefore energy-saving effect is extremely significant when compared with similar products, saving up to 50% -90% or more. Non-occurrence of secondary pollution: due to a direct serial work, without setting the ground storage tanks, thus ensuring water sanitation standards, water quality, non-occurrence of secondary pollution. High degree of automation: The device is completely simulate the human brain intelligence technology to the automatic control equipment without the need for someone on duty. Long life: The device uses frequency conversion technology to achieve soft-start pumping systems to run, no high-current shocks, when compared with traditional technologies, equipment, life expectancy more than doubled, the failure rate is almost zero. Protection of a full-featured: The device has over-voltage, over current, overload, water and other water protection functions. When the tap water down without water, the device will automatically shut down automatically when you boot runoff not only protects the pump motor, but also to save energy. Non-stop water blackout during a power outage on their own to regain the atmospheric pressure water supply. Applications: Be used in any areas with inadequate water pressure to pressurized water supply. New residential district or a building such as for domestic use. Lower water pressure can not meet the requirements of the fire water. Transformation of the original pressure water supply equipment.
