Mini Welded Plate Heat Exchangers

Tranter Mini-Welded Heat Exchanger as an acid coolerAll-welded, 316L SS or titanium construction makes the MAXCHANGER highly durable in demanding applications.

Description And Benefits of Mini-Welded Plate Heat Exchangers

A quick look at the MAXCHANGER® Mini-Welded Heat Exchanger may lead you to dismiss it as a compact brazed heat exchanger (CBE) type. Yet there is nothing brazed in this unit—its standard materials are all-welded 316L SS or titanium. In most applications and even under extreme conditions, compared to other smaller size heat exchangers, MAXCHANGER is truly worth a second look.

Further enhancing its compact footprint, the MAXCHANGER offers flexibility in nozzle positioning. This helps the unit to fit virtually any ultra-compact heat exchanger requirement. This footprint flexibility makes MAXCHANGER truly the design engineer’s friend. With MAXCHANGER durability, the unit will often outlive the system service life, eliminating the need to design for service access and more added space.

Much Smaller and More Efficient Than Shell &Tubes

MAXCHANGER is not only robust, but it is also efficient. This gives the exchanger an enormous heat transfer edge over shell & tube exchangers. The unique dimpled plates, combined with countercurrent flow, produce extremely high “U” or "K" values, immediate thermal response and a close temperature approach capability of less than 1°C (2°F). High turbulence prevents fouling or scaling that wastes energy and requires disassembly of S&Ts for cleaning.

All in all, MAXCHANGER gives you shell & tube performance under demanding conditions, for a fraction of the installed mass and footprint, with the bonus of energy and maintenance savings.
