Prag was amongst the first to develop a completely indigenous Plate Heat Exchanger for Locomotive applications with the introduction of PHE-01 Plate Type Lube Oil Cooler in 2004.

Designed to offer the most optimum thermodynamic performance, the PHE-01 heat exchanger has been in use on several Diesel-Electric Locomotives in India for more than 10 years.

Heat transfer SS plates and Rubber Gaskets used in Prag PHE-01 are manufactured on fully automatic presses in accordance with the highest quality standards. Our team is well equipped to develop custom-designed Plate Heat Exchangers as per specific customer requirements.
