PSI Engineering Systems

PSI Engineering Systems

PSI Engineering Systems is one of the leading manufacturers of Boiler & Turbine auxiliary systems, which are essential parts of a power plant. They are modular skids (i.e.) ready-to-use equipment. These products to various other industries like paper mills, sugar mills, etc, where boilers are being used. They also design and fabricate special high-tech equipment for specific customer requirements.

PSI Engg group is over 35 years old, founded in 1975. PSI Engineering Systems confirm to most accepted international standards like ASTM, ASME, DIN, etc., and are manufactured according to approved quality plans. Components are sourced from the best international suppliers. Quality Control checks are carried out at every stage. Products have been accepted by all leading inspection agencies and major users/OEM's.



Very compact, save space, and be convenient for plant installation as well as plant operation. Advanced instrumentation features can be incorporated into the systems, for compete auto- control & data logging, through plant interface. Considerable design and detailed engineering efforts are required for designing individual components of the skid, and in integrating the components into making a compact and efficient system. Our Dosing systems are available as manually operated, as well as fully automatic systems, which include all instrumentation and controls for sensing & Correcting pH conductivity & other parameters.
