Pressure Reducing and Desuperheating Stations

Overview

PRDS Station: Your One-Stop Solution for Precise Steam Conditioning

Combined PRDS Station

The PRDS Station, or Pressure-Reducing & Desuperheating Station is a critical component in industrial processes requiring precise steam control. It combines two essential functions:

1. Pressure Reduction: A pressure control valve (PCV) regulates the steam pressure to the desired level, preventing damage to equipment and optimising efficiency.

2. Temperature Control: A desuperheater(DSH), working in conjunction with a temperature control valve (TCV), mixes atomised water with steam, effectively reducing its temperature to the required set point.

The PRDS system is a unified solution comprising carefully designed components working in perfect synchronisation. From precise pressure reduction to efficient desuperheating and intuitive control systems, each element collaborates to deliver a reliable and optimised performance.

IndiTech PRDS station is a modular steam conditioning unit that reduces the steam pressure & temperature at the point of usage, and it can be directly installed into your existing steam network. We offer a wide range of PRDS Stations designed for diverse applications and capable of ensuring optimal performance.

IndiTech PRDS Stations are key to achieving the perfect steam pressure and temperature balance for your specific needs.

Enjoy precise pressure control, consistent steam quality, and worry-free operation with IndiTech’s advanced range of PRDS Stations.

Applications

HP/LP Process PRDS:

Multiple industries, like Sugar Mills, Paper Mills, Chemical Plants, Textiles, etc., utilise PRDS Stations to control and reduce the pressure and temperature of steam, ensuring precise thermal conditions for downstream processes.

Ejector & Gland Sealing/Auxiliary PRDS:

Ejectors are the devices used to create a vacuum in various processes, such as condensers or certain chemical processes. Gland sealing systems are crucial for preventing steam leakage and maintaining the integrity of the turbine casing. PRDS Systems helps maintain the desired steam pressure and temperature for optimal efficiency.

Deaerator Pegging PRDS:

Deaerator Pegging PRDS reduces the pressure and temperature of steam before it enters the deaerator, ensuring efficient oxygen removal. This optimises boiler performance and protects downstream equipment.

Turbine Bleed/Extraction PRDS:

The Bleed / Extraction PRDS station regulates and lowers the pressure and temperature of steam extracted or bled from the turbine, optimising its utilisation in downstream processes.

Turbine Bypass/Dump PRDS:

The Turbine Bypass PRDS System helps to control and reduce the pressure and temperature of steam in the turbine bypass line, ensuring optimal conditions for turbine operation by removing excess pressure and heat.
