Carraro - Desuperheater VariFix
The VariFix nozzle head with 1 to 15 nozzles provides excellent sputtering in a fixed area. In each nozzle, an internal vortex ring is built in, which ensures a very small size of the water droplets also at low differential pressures
They are primarily intended for use where the load is almost constant. Moderate strain variations can be controlled via the guaranteed rangeability
The atomizing angle of each nozzle is adjusted so that water droplets on the steam line pipe system are minimized
One or max two nozzle heads are mounted at the end of the tubular valve and the valve is connected to the steam line by means of a flange and water connection at the top (standard) or side connection (on request)
It is recommended to install a filter (strainer) before the water connection
