Welded PHE: High-Efficiency Heat Exchanger for Industrial Applications

What is welded PHE? Welded plate heat exchangers (PHE) are compact thermal transfer devices.

Welded PHEs are robust heat exchangers designed for high-pressure and high-temperature applications. Unlike gasketed models, they use laser-welded plates for leak-proof performance, ideal for harsh industrial environments like chemical processing, oil & gas, and power plants. Their compact design maximizes surface area for superior heat transfer efficiency, reducing energy costs by up to 30% compared to shell-and-tube units.

How does welded PHE work? Heat transfer via corrugated metal plates.

Welded PHEs transfer heat between fluids through thin, corrugated stainless steel plates welded in alternating patterns. Hot and cold fluids flow counter-currently, optimizing thermal exchange. The welded construction eliminates gasket failure risks, ensuring durability at temperatures up to 350°C and pressures exceeding 40 bar. Industries report 20% higher efficiency and 50% less maintenance versus traditional exchangers.
