What is a Gas-Gas Plate Heat Exchanger?

Gas-Gas Plate Heat Exchanger

A gas-gas plate heat exchanger is a highly efficient heat transfer device designed to recover heat from high-temperature exhaust gases and transfer it to incoming cold air or other gas streams. Unlike traditional heat exchangers, its compact plate structure maximizes the heat transfer surface area, achieving thermal efficiencies of 60% to 80%. The exchanger consists of thin, corrugated metal plates (typically stainless steel) that create separate channels for hot and cold gases, allowing heat to pass through the plates without mixing the gas streams.

This technology is particularly suited for industrial processes that generate significant waste heat, such as drying systems in ultrasonic cleaning machines used for hardware components. By capturing and reusing this heat, the gas-gas plate heat exchanger reduces the energy required for heating processes, lowering operational costs and carbon emissions.
