AB5900 - Variable Orifice Desuperheater
Compact steam desuperheater for accurate temperature control.
Compact design allows evaporation within 1 meter of pipe.
High rangeability ensures precise cooling across wide flow ranges.
Easy to maintain with only six major components.
The AB5900 Variable Orifice Desuperheater delivers reliable and precise steam temperature control in a compact design. Ideal for limited-space applications, it ensures complete evaporation within just 1 meter of pipe length and a short distance to the temperature sensor (under 5.5 meters). With a high rangeability and accurate control near saturation points, it enhances plant efficiency and productivity. The robust construction features only six major components, reducing maintenance needs. Built for low steam velocities and demanding conditions, the AB5900 offers an efficient and space-saving solution for industrial steam cooling in power plants and process industries.
