PUREX: Point-of-Use Heat Exchangers

Featured Supplier: Exergy

If your process involves dispensing water-for-injection (WFI) or purified water (PW), there are often many advantages to specifying an efficient and reliable point-of-use (POU) heat-exchanger system. PUREX is a revolutionary turnkey POU system from Exergy that has enabled users to maximize safety and efficiency while also simplifying their process.

Features & Benefits

PUREX POU systems are engineered to dispense temperature-controlled WFI and PW to meet the high-quality requirements and hygienic standards of the pharma, biopharma and other life sciences industries. Each unit is ASME BPE compliant and receives comprehensive factory acceptance testing (FAT) with optional site factory acceptance testing (SAT) also available. The system features advanced automation options allowing for integrated management of the POU system and client controls. PUREX POU models range from standard pre-engineered units to highly customized designs and have flow rates from 0.5 GPM to 25 GPM.

Below are several key benefits of using the PUREX POU system:

  • Easy to install, operate, and maintain
  • Automated or manual operation
  • 316L SS Construction
  • ASME BPE compliant
  • All product contact surfaces passivated
  • Fully drainable with no dead legs
  • Compatible with CIP & SIP
  • Instant hot or cold WFI or PW available at POU
  • Sanitary Double-Tube Sheet heat exchanger

How It Works

Below is a summarized process flow description to illustrate how the system functions during various operational stages:

Typical Applications

    • Water For Injection (WFI) systems
    • Purified Water (PW) systems
    • Point-of-use cooling
    • Cool WFI/PW from 80-85°C to 20-40°C
