Why NONAIR®

NONAIR® separates air and other gases from circulating water in heating and cooling system.

NONAIR® is developed from a new patented principle.

Traditional Separators are usually formed as vertical vessels with horizontal pipe connections. Inside it use to be a mesh or a "shaving brush" or metal rings on which surface the Micro bubbles will stick to, when the media flows in the Separator.

NONAIR® is designed as a horizontal vessel with horizontal pipe connections where a part of the flow is let in to a separation chamber. The Micro bubbles can, due to the turbulence free conditions, gather together and finally be separated. The advantages we use to call attention to are listed below:

  • NONAIR® has a documented high efficiency of micro bubbles separation.
  • NONAIR® has a very low weight both empty and filled with media. As we use Stainless Steel 316L we can reduce the thickness and thanks to that the weight will be reduced. As an example, a NONAIR® in DN125 weighs only about 20% of a traditional Separator and filled with media less than twice the weight of the connection pipe with the same length. This will minimize the cost for transportation all the way from the manufacturing plant to the site. Well on site the cost of handling the unit and for suspension attachements will be lower.
  • NONAIR® has low or insignificant pressure drop as it has full flow through. This is because there is nothing along the flow line that creates pressure drop, no mesh, no "shaving brush", no metal rings. Traditional separators can have a pressure drop of many thousands Pa at a flow rate of 1 m/s. This will bring the energy consumption up to unnecessarily high levels. The use of NONAIR®, with a pressure drop of only 50 Pa at a flow rate of 1 m/s, will reduce the need of pump capacity and cost for pump energy.
  • NONAIR® has the markets most extensive connection alternatives:
    • Male threads for R25, R40 and R50
    • Female threads for R20 - R50
    • Welding ends in Stainless Steel 316L for DN40 - DN400*
    • Welding ends in Carbon Steel for DN50 - DN400*
    • Flange connection with collars in Stainless Steel in 316L and loose flanges in Silumin or Galvanized Steel or Stainless Steel for DN40 - DN400*
    • Flange connection with Welding neck flanges in Stainless Steel or Carbon Steel, even in ASTM standard for DN40 - DN400*
    • Grooved pipe ends in Carbon Steel or Stainless Steel 316L for use with grooved connections like Victualic, Grinnell or similar for DN50 - DN400*
*the Strainer model stops at DN150.
  • NONAIR® has no risk for inside corrosion due to its Stainless material. For traditional Separators this risk is obvious. The separated air will be found in the top of the separator waiting for to be let out through the Air-Vent. If the material is corrosive the separaor will get corroded in the zone where separated air is present.
  • NONAIR® has no risk for outside corrosion due to its Stainless material. For Separators made of Carbon Steel this risk is obvious, particularly when the media temperature is low and condensation occurs. Even if the equipment is insulated there will always be leaks that will let humid air in.
  • NONAIR® has no general limitation for the flow rate.
  • NONAIR® is designed as a horizontal vessel with little extention outside the centerline. This means that the NONAIR® could in most case be mounted in-line without the need of expensive tubing to get the Separator to the same level as the pipe route.
  • NONAIR® is designed to be supplied with a detachable automatic de-aerator. With built-in ones it is necessary to empty a great deal of the system if maintenance is needed with the automatic de-aerator. With the NONAIR® this work is easily done.
  • NONAIR® has as standard the pressure grade PN10 but can on request be manufactured even in PN16 and PN25 for DN40 - DN400*.

*the Strainer model stops at DN150.

Compare NONAIR® with other brands for the parameters above and the advantages with NONAIR® will be clear. If you value these advantages the choice is easy.
