Trusted by Public Utilities: Efficiency of Refurbishment

Trusted by Public Utilities: Repeated Plate Heat Exchanger Refurbishment for National Power Plant

A leading national energy provider operating large-scale public power plants required specialized refurbishment of multiple plate heat exchanger (PHE) units used in its industrial cooling systems. As part of its scheduled maintenance strategy, the organization initiated a competitive public tender to secure a reliable, certified technical partner.
