For hydrogen applications, in addition to PCHE, it is also possible to use brazed plate exchangers, which however offer much lower pressure limits, but they guarantee as well sealing capacity and tightness against leaks and fluid mixing.
First large PCHE heat exchanger for the oil & gas sector in Microchannel Devices, sized and built to meet the stringent requirements of the ASME regulations for use in an offshore platform.
Compactness, high thermal efficiency and reliability and the extreme versatility of PCHE heat exchangers make them an ideal choice for gas cooling during the compression phases in hydrogen refueling stations.
Tempco launches a new site dedicated exclusively to the innovative technology of PCHE heat exchangers, to jointly explore and develop cutting-edge applications in fields such as hydrogen, sustainable mobility, oil and gas and nuclear energy.
Tempco PCHE exchangers for hydrogen cooling in fuel cell technologies are featured in an article on the January issue of ICP magazine, the diffusion bonding construction process allows the exchangers to operate at extreme pressure and temperature levels.
Diffusion Bonding is a special welding technology allowing to obtain innovative plate heat exchangers resistant to very high pressure and temperatures, to be employed in sectors such as aerospace, oil and gas and hydrogen applications.
With the increasing use of natural refrigerants in industrial equipment against climate change it becomes even more important to carefully calculate the volume of brazed plate heat exchangers, taking into account a variety of factors.
Cleaning operations on brazed plate heat exchangers through chemical washing, to carry out as soon as there is a signal of pressure drops in order to avoid complete clogging of the exchanger.
PCHE plate heat exchangers allow multistream design thanks to the special mechanical etching process employed to realize the channels, in addition to high and extreme pressure and temperature resistance thanks to diffusion bonding welding technology.
Tempco is exhibiting with Microchannel Devices at Hydrogen Expo, 27-28 September in Bremen, presenting the innovative PCHE heat exchangers for hydrogen and fuel cells applications, realized using Diffusion Bonding technology.
