The AB5700 Variable Orifice Desuperheater from IMI is designed for high-capacity applications, delivering precise steam temperature control with advanced features. Its variable orifice design ensures efficient atomisation across wide flow ranges, achieving a turndown ratio of 50:1 and maintaining temperature control accuracy within ±3°C. Suitable for large-scale steam piping (up to 48"), the AB5700 handles high thermal stresses, allowing a 400°C temperature difference. It eliminates the need for atomising steam and features a self-draining system to reduce maintenance requirements. With a robust design tailored for demanding conditions, the AB5700 is ideal for power plants, petrochemical facilities, and process industries.
