IST specializes in design, manufacture and installation of Once Through Steam Generators (OTSGs) for Power Generation and Enhanced Oil Recovery (EOR) Applications.  

The Power Generation OTSG provides a simpler, smaller, and more efficient alternative to drum-type HRSGs.  IST has become a market leader in the 10 to 100 megawatt size range gas turbine with installations in 19 countries around the world. 

At IST we found a better way! Our SQ90™ Enhanced Oil Recovery OTSG guarantees 90% steam quality, better than the norm at 75-80%.  The SQ90™ reduces operating costs and environmental impact.
