Smart Air Vent

Short Air vent -Positive Flow Modulator (PFM)

Nuetech Solar Systems Pvt. Ltd. R&D team has an invention developed, relating to an equipment for Modulating the positive flow of hot water from a roof top solar water heater in the hot water lines of houses, apartments, residential / commercial buildings.

The present innovation - “Positive Flow Modulator” (PFM) is patented device mounted at the outlet pipe of the hot water tank of the solar water heater system. This device is very effective in its function, easy to install and can suit most of the solar water heater systems commercially manufactured.

The innovation will eliminate all the lengthy air vent problems and always provide Positive Flow of water in the hot water pipeline.

Advantages of Smart Airvent

  1. Eliminates lengthy Airvent pipe/assistant or break level tank and air relief valve (ARV).
  2. Allows the Solar water heater to work with slightly elevated pressure for better performance.
  3. Overall performance improvement of around 10% of the solar water heater system.
  4. All in one unit to release air lock, release excess pressure, releases steam formed inside hot water tank.
  5. Rugged and foolproof design.
  6. Positive flow of hot water at tap end.
  7. PFM works for PRD / pressurized tank systems also, NO PRV and ARV.
  8. Easy to install and safe to handle.
  9. One standard model for varying sizes and types of SWH.
  10. Standard product to go with SWH systems.

Problems Identified with lengthy airvent pipes for solar water heaters:

  1. Airvent pipe are too tall for solar water heater system size.
  2. Complicated to support tall Airvent pipe on the roof.
  3. Aesthetically not appealing.
  4. Airvent pipe generally will not stand vertical pipe will bend due to heat and or its own weight.
  5. Hot water stored in the Airvent gets cold soon and get discharged first each time into the flow of cold water in the hot water line which will reduce the efficiency of the system considerably.
  6. Hot water pipe leakage because of shaking Airvent pipe due to wind or birds sitting on it or its own weight with hot water.
  7. Airvent pipes are non-standard and need to be designed at the site.
  8. Airvent pipes are the attraction for monkeys on the roof tops of buildings and often break them by trying to climb or swing on the Airvent pipe resulting in draining of the entire water from SWH and cold water tank.
