PRDs

PRDs (Pressure Reducing and DeSuperheating Systems) are engineered steam conditioning solutions that precisely control steam pressure and temperature in industrial processes. Used extensively in steam engineering applications, PRDs deliver reliable performance for pressure and temperature reduction, improving efficiency and safety in steam-dependent operations.

Applications:
PRDs are essential in thermal power plants, cogeneration facilities, and heavy industrial plants where steam quality and control are critical. They are typically employed in turbine bypass systems to safeguard turbines during start-up or shutdown, and in steam distribution networks to condition steam for downstream processes. PRDs also help manage pressure and temperature for process heating, extraction, and auxiliary steam systems, offering precise control for complex steam applications.

Equivalent Standards:
Chemtrols’ PRDs comply with recognized industrial standards such as ASME Section VIII, Division 1, and are available with certifications including ANSI pressure classes up to 2500# and IBR certification. Options for PED and CE stampings are available for export applications, assuring global quality and safety compliance.

Key Features:
These systems combine pressure reducing valves and atomizing spray systems to effectively reduce steam pressure and temperature in a controlled manner. Available in split and combined configurations, PRDs offer flexibility to suit diverse plant layouts while optimizing footprint and piping costs. Temperature and pressure are managed through integrated control loops using precision sensors, transmitters, controllers, and control valves designed for steam services.

Benefits for Data Acquisition & Management:
Integration with modern data acquisition and control platforms enables real-time monitoring of pressure and temperature parameters, automated control actions, and historical trend analysis. This enhances operational transparency, supports predictive maintenance, and drives energy efficiency improvements across steam systems.
