The water supply system is an important and indispensable part of production and life.The traditional method of water supply covers a vast and gigantic sector. investment in infrastructure is high, and the main disadvantage is that the water pressure can not be kept constant, resulting in deficiencies in the precess and causing it to malfunction. As frequncy inverter technology evolves, water supply equipment, with constant pressure by varying pump speed, has fundamentally solved these problems. With advanced technology, adjustable constant water pressure, easy operation, reliable, energy saving an high degree of automation, the variable frequency constant pressure water supply technology is widely used in various industries, such as: sanitation, industral for example in the treatment of effluents, agribusiness, food industry, water supply in condominiums, etc.

With this demand in mind, Provolt sells the PI500-W frequency inverter, with powers from 0.5CV to 500CV, in order to provide the market with one of the best and most sophisticated technologies when it comes to pump pressure control for sanitation and water supply. The PI500-W allows the control of up to 4 pumps simultaneously, performing the entire operation automatically, without depending on human action, performing the use of pumps alternately after a certain period of time in operation, opetmizing the useful life of motors and pumps, reducing energy consumption, which provides more safety and longevity to the environment. 

Provolt also supplies items such as: Harmonic Filter, Power Factor Correction Filter and EMI Filter. In order to adapt to the standards.
