Carlo Gavazzi RSWT Series of soft starters for pumping applications

Carlo Gavazzi has announced the launch of its RSWT Series, a self-optimizing soft starting solution for water pumps up to 75Hp. The RSWT Series is a 3-phase pump soft starter, in which all three phases are controlled to achieve current balancing on all phases, to minimize vibrations during starting and stopping of centrifugal pumps and to minimize the inrush current. According to Carlo Gavazzi, the RSWT Series achieves smooth starting and stopping, with minimal setting adjustments required from the user. Within three to six starts, the RSWT Series reaches optimization. The self-learning routine is active at ensuing starts to ensure optimal starting and stopping parameters are used even if the load changes. This results in less water hammering and reduces the risk of cavitation.

The RSWT Series is available from Carlo Gavazzi’s North American network of sales offices and distributors, or at www.GavazziOnline.com.
