Clean Steam Generator

for Healthcare Sterilisation

Masthead background


The CSG-HS is a clean steam generation system designed to guarantee steam quality under rapidly fluctuating load conditions that are typical of autoclave demand.

To get the very best from your decontamination process, steam should be dry and free from non-condensable gases (NCGs)*. Designed for maximum performance and reliability, the CSG-HS features an integral degasser that removes undesirable non-condensable gases (NCGs) from the feedwater and delivers good quality dry steam at all times.  

*as set out in BS EN 285:2015

Product features

  • Designed to exceed the requirements of EN285
  • Configurable options to suit individual requirements
  • Easy to maintain with minimal tools required
  • Intelligent PLC with Spirax Sarco developed SIMS technology

CSG-HS for your Central Sterile Services

The CSG-HS is designed for maximum performance and reliability – a steam supply you can count on without interruptions to your sterilisation processes

Unlike alternative steam solutions, the CSG-HS can be housed externally from your main Sterile Services Department. This means when routine maintenance is required, you can do it without entering the sterile environment – so less risk of contamination and less interruption to your sterilisation processes.
