Clean Steam Generator

for Healthcare Sterilization

Masthead background


The CSG-HS is a clean steam generation system designed to guarantee steam quality in all dynamic load changes to match the application.

Our specialist engineers conducted a worldwide research programme to understand the needs and challenges that our customers were facing in the generation of high quality steam within hospitals and healthcare, in particular the well-known industry problem of wet packs in the sterilization process.

This research formed the foundation for a ‘ground up’ redesign of our CSG portfolio and the development of CSG-HS, enabling us to offer a clean steam generation solution that consistently delivers, with no drop in reliability even when demand peaks.

CSG-HS includes a range of innovative design features and is supplied packaged and ready to install with simple commissioning

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 sterilization 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 sterilization processes.
