Oventrop Aquanova - Aquastrom balancing valves

  • Aquastrom C and Aquastrom VT

    for the balancing of hot water re-circulation systems. These products are commonly found in medium to large residential, commercial, hotels and hospitals etc. as being part of the potable hot water supply, fit the hydraulic plumbing sector.Both products are now Watermarked and have been installed locally across Australia.

  • Aquastrom C

    is a manual balancing valve, and Aquastrom VT is automated set and forget temperature and residual flow management.

  • Aquastrom VT

    also has a thermal disinfection process. Where raising the boiler temperature for a short period of time to circa 65c+ the valves open 100% and provide a thermal flush of the recirculation system. This thermal flush assists to kill off legionella spores, as they die swiftly at temperatures above 65c. This is further explained in the brochure and as part of the Aquanova technical seminar that Masterflow offers.

Masterflow offers its distribution partners and customers, potable hot water recirculation system design drawings in our OV selection program.

This enables the consultant and contractor to have complete confidence in the system design, as we include the recirculation system pump head loss calculations, and precise balancing valve selections and pre-setting details. This ensure the system is balanced on thermal balancing techniques, not just flow as most consultants still call for in designs. Balancing on just flow is completely wrong, to ensure system hygiene and energy efficiency is maintained.

The Aquastrom range, is a valve that a plumber can easily set and adjust. It is supplied with the correct instrument a plumber can read, a thermometer. All others in the market require a manometer, as used in the HVAC industry to commission and prove precise flow rate management.
