The existing steam humidification system was incapable of supplying the required amount of humidity to the hospital in general and to the operating rooms in particular.
The system, as designed, was based on generating steam in one boiler, and using that steam in a Clean System Generator to produce steam to humidify. The system was energy intensive, inefficient and incapable of providing required levels of humidification. A steam plant/humidification retrofit was required.
Earthwise Environmental proposed eliminating the Clean Steam Generators and designed a water chemistry program that exceeded the quality and purity requirements of the hospital. A new steam boiler with reverse osmosis treatment of feedwater was installed. Energy waste from inefficient steam generators was eliminated and sufficient steam could now be generated to meet humidification needs.
$1.35M project to eliminate clean steam generators, install a reverse osmosis system and restore humidity levels
- High quality/purity steam for direct humidification requirements
- 1.3 million gallons of water saved per year
- $348,000 energy savings annually
