Carraro - Desuperheater VariSpring
VariSpring nozzle head has a larger process window than fixed-area nozzles and is spring-loaded.
VariSpring is controlled automatically by means of an installed control valve on the outlet side. Thus, the desired media speed and the need for steam cooling are maintained.
Can be supplied with water connection at the top (standard) or side connection (on request).
It is recommended to install a filter (strainer) before the water connection
