Pure Steam Generators

Pharmatec Pure Steam Generators utilize an efficient evaporation column identical to the Pharmatec Multiple-Effect Water Still, thereby providing the highest quality Pure Steam. When condensed, the pure steam exceeds the requirements of the latest US Pharmacopoeia for Water-for-Injection. Each unit is produced to comply with the US FDA’s current Good Manufacturing Practices and is manufactured in accordance to ISO 9001 quality standards.

  • All stainless steel construction – no rusting/rouging
  • Extremely tight pure steam pressure control – no pressure regulator needed
  • Industry standard control system – Allen-Bradley PLC or Siemens
  • Non-proprietary components – readily available from local sources
  • Wetted evaporator – less stress on welds, more corrosion resistant
  • Two-year pressure vessel warranty
  • 100% drainable design – no standing water
  • Sanitary diaphragm valves used on feed water, pure steam and WFI lines
  • 25 Ra electropolished finish on feed water & product piping
  • Extensive validation documentation – reduces on site validation time

Pure Steam Pressure Control
Pharmatec Pure Steam Generators provide extremely tight control of the pure steam pressure with ±1.5 psig (0.1 bar). A pressure transducer monitors the pure steam pressure and automatically varies the heating steam pressure to maintain the operator-selected set point. Feed water is controlled by a modulating control valve. This precise control of the pure steam eliminates the need for costly sanitary pressure reducing valves in the pure steam header.

Tension-Free Evaporator Design
The Pharmatec Pure Steam Generator utilizes an evaporator design that allows the evaporator tube bundle to be totally immersed in feed water. The shell side of the evaporator contains the heating steam. The feed water is always present whenever heating steam is applied to the evaporator. As a result, when heating or cooling occurs in the pure steam generator, the shell and tubes will expand or contract at the same rate. This eliminates tension to the tubes, shell, welds, and reduces stress corrosion. The feed water immersed tubes allow for steady generated steam flow upward in the tubes, which greatly reduces
the scaling effect prone to dry falling film. As a result of this
safe design, Pharmatec evaporators are warranted for a full two years.
