Diffusion Bonded Heat Exchanger From Kelvion

Kelvion said its new advanced diffusion bonded heat exchanger— K°Bond — is up to six times smaller than conventional shell and tube heat exchangers and is designed for operations with space restrictions.

It is designed to work reliably with pressures up to 1000 bar and temperatures from -200⁰C to 600⁰C. In addition, it provides a high heat transfer rate, allowing temperatures approaching up to 2⁰C, thanks to the proximity of the fluids, the company said.

The K°Bond is composed of a series of stainless steel plates integrally welded together by pressing at high temperature – a process known as diffusion bonding. Each plate is first chemically etched with microchannels appropriate to the specific application. The bonding process creates a solid core of metal. As required, multiple cores can be welded together.

Diffusion bonding ensures the highest levels of safety, free from the risk of leakage, and high resistance to cyclic services, Kelvion said.

Kelvion said its extensive industry knowledge and welding experience inspired the development of the K°Bond. It is suited to a range of oil & gas processes, including offshore plants and floating storage regasification units and power related hydrogen and supercritical CO2 processes.
