MDAV-S Venturi-style Desuperheater

Venturi-style desuperheater for accurate steam temperature control

The MDAV-S desuperheater is designed for the attemperation of steam in small diameter pipelines. It features a single spray water nozzle installed into a flange, allowing highly accurate control of the steam temperature down to 8°C / 15°F above the saturation temperature. The spray water is controlled through an external valve and injected into the steam flow through a fixed nozzle. The venturi design guarantees a high steam velocity at the point of injection, which improves water evaporation and minimises the risk of water impingement on the pipe wall.

• Accurate temperature control, down to 8°C / 15°F above the saturation temperature.
• Fast evaporation and atomisation of cooling water thanks to the venturi design.
• Minimal maintenance required – no moving parts.
• Simple, space-saving installation for easy integration into existing systems.
