Sisu’s FreeHeat Ammonia

Vaporization System

Ideal for: 

  • New Installations

  • Retrofit

  • Reduced Maintenance

  • Increased net Power Production

  • Simplified Installation

  • Turnkey Retrofit Design

 

Sisu’s proven patented FreeHeat Ammonia Vaporization is supplied for new installations but is particularly suited to replacement opportunities where the old electric heaters have become problematic and/or unreliable. New units can save 100-200 kW per unit because FreeHeat replaces the electric heaters and their control systems, eliminating the auxiliary load so that power can go “out the gate” to net power production. The FreeHeat reduces maintenance and downtime and provides faster startups and quicker ammonia injection cycles, thereby reducing total NOx emissions.

FreeHeat Anti-Icing

Ideal for: 

  • New, fully Integrated Designs

  • Retrofit Designs for Old, failing Units

  • Turnkey Retrofit Installation

 

Sisu’s FreeHeat Anti-Icing System can be provided with a complete ERU or as a stand-alone component. Many old heated-air systems installed at the turbine outlet have become problematic due to poor temperature resilience. The Sisu in-line design eliminates this problem. Sisu’s new installation design utilizes an internal coil to accept both active and static modes.
