DeFlo VSD – Variable Spray Desuperheater
Mascot’s Variable Spray Desuperheater (VSD) stands out with a remarkable turndown ratio, adjusting the spray water with the in built control valve. The VSD ensures consistent atomization across all flows due to a constant nozzle pressure drop. It features a swirling hollow cone spray pattern for water exit at a higher velocity and better atomization. Size ranges from 0.5″ to 4″ water inlet line, with pressure ratings of 150# to 4500#. The VSD’s versatile design accommodates various steam pipelines with no size limitation, delivering an impressive turndown ratio of 80:1.
