Carraro - Desuperheater VariVent

VariVent desuperheater for control and reduction of steam temperature. The venturi-shaped nozzles efficiently atomize the water and are activated by a control valve mounted before the desuperheater. They are primarily intended for moderate loads and where precise temperature control is crucial

Vertical water connection at the top (others on request). It is recommended to install a filter (strainer) before the water connection
