Benefits

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
