Product Features

• Suitable for difficult operating conditions, high quality temperature control and avoidance of temperature shocks (valve and piping)
• Allows cooling operation when all other systems typically fail
• For optimum temperature control close to saturation with a control ratio of up to 100:1
• Ultimate cooler for low-speed steam cooling applications, large bandwidth and small distance/separation to saturation
• The additional cooling water and atomizing steam control valve must be considered in the planning

Applications

• For low speed, highly adjustable desuperheater applications and low saturation separation.
