Power generation is a complex arena. Explosive environments in fossil power plants and radioactive contamination environments in nuclear power plants require very specialized expertise and experience. Hill Country Engineering provides extensive knowledge of particle dynamics in a variety of gaseous and liquid mediums; this knowledge and understanding is essential to the design and analysis of critical safety products in these markets. Our experience includes design and analysis of portable HVAC and material conveying systems meeting the unique explosion resistant requirements of the fossil power industry and radiological control/containment requirements of the commercial nuclear and DOE sectors.
