A.R.I.’s software-aided solutions changed the rules of the game by bringing the customer and the solution provider into closer contact.

Providing customers with learning tools and hands-on training, A.R.I. has increased their awareness and ability to conserve water and energy, reduce water pollution, and reduce water losses in all types of pressurized liquid transmission systems.

Firmly committed to quality and to protecting the environment, Aquestia is ISO 9001, OHSAS 18001 and ISO14001 certified.

What We Do

The A.R.I. product range offers a complete line of air valves, check valves, control valves and unmeasured flow reducers (UFR), as well as providing software system analysis for surge and air valve sizing and placement.

Committed to solving problems such as pipeline bursts, fractures and cracks, A.R.I.’s process begins by using its proprietary software system, ARIavCAD, to carry out a system analysis that helps reduce surge-related phenomena. The most efficient A.R.I. air valves, in the correct size, are then selected, and located on the liquid transmission system.

A.R.I.’s products and analysis solutions are marketed to the following segments:

  • Water supply and wastewater disposal systems (urban and rural).
  • Industrial applications (desalination plants, mining and gas industries, hot water systems).
  • Agriculture and landscape.
