Pure steam generator

Pure Steam Generators:

Steam generators are units capable of separating drops carrying impurities (particles, pyrogens, etc.) and therefore produce constantly high quality pure steam.

For this purpose, the steam generator usually has the following parts:

A column shaped tank or expansion chamber

– A sanitary heat exchanger or electrical elements for heating and evaporation of water

The pure steam generators consist of a vertical pressure container, in the form of a column divided into two parts. The lower part consists of a tubular heat exchanger, with a double tube sheet (DTS), connected at the top to an expansion chamber or separating column, which allows the steam to flow upwards and prevents water droplets from exiting the chamber To improve the energy efficiency, the preheated water is introduced into a tank with an exchanger, where degassing occurs. The system is supplied as a compact unit on a skid and all its components are readily accessible.

Accessories & Options

  • Pure steam condensation unit for the production of distilled water
  • Energy recovery and degassing system
  • Inlet water and pure steam monitoring
  • Graphical recorder
  • Condenser for sample taking
  • Pressure reducing valve



The design of the equipment offers excellent performance for steam production for use in pharmaceutical production:

Sanitary design: Generator designed in the form of a column, with the heat exchanger at the bottom and the expansion chamber above, which guarantees dry and saturated steam, free from droplets, which fall due to the effect of gravity. The impurities are eliminated or intermittently drained from the bottom of the column.

Robustness and reliability: The heat exchanger consists of a double tube sheet (DTS), constructed from AISI 316L stainless steel. The column is thermally insulated with rock wool and it is clad with AISI 304 stainless steel sheet. The skid is made out of AISI 304 stainless steel.

Safety and easy operation: Operation is fully automated by means of sensors and the unit is equipped with the required safety and protection equipment, providing warning signals and alarms.

A PLC performs the control and management of the equipment. The equipment can be easily supervised and controlled by means of a touch screen in the control panel.

Quality guarantee: The unit is fully prevalidated in the factory to test its compliance with EN 258 (HTM 2010) standards in terms of saturation, heating and non-condensable gas levels.


Pure steam is mainly used in the pharmaceutical industry and in biotechnology for:

  • Sterilization
  • Water for injection generation (When the laboratory requires water for injection but in very small amounts)
  • Clean room humidification
