Hydrogen Cooling Systems for Turbine Generators - Praxair

Hydrogen Cooling Systems
for Turbine Generators
Overview: Praxair’s hydrogen cooling technology provides customized cooling systems for
turbine generators to help optimize heat removal and improve system operating efficiency.
Praxair’s practical, results-focused approach to system design provides a hydrogen (H2 ) system
customized to your specialized needs. Our full range of hydrogen supply options provide the
capacity and purity you require, at a cost structured for today’s highly competitive market.
Praxair Praxair bulk gaseous hydrogen is 99.95% pure and cryogenic liquid is 99.997% pure. These purities
Hydrogen Purity improve hydrogen’s ability to dissipate heat within the generator. Higher H 2 purity also translates to lower
Benefits gas viscosity and reduced windage, resulting in better operating efficiency and expanded generating capacity.
