OPTIMAX™ Heat Exchanger


Watlow has over 40 years of experience designing and manufacturing heat exchangers, and we have the knowledge, experience and expertise required to create optimal heating solutions. Watlow has taken the tried and true, critical design criteria and improved it to create a new generation heating technology – the OPTIMAX™ Heat Exchanger.

Watlow’s new OPTIMAX™ technology combines optimal fluid dynamics, efficient heat transfer, low pressure drop and a compact and reliable package to create a world-class system solution.

Watlow’s EFD (enhanced fluid dynamic) technology provides advanced flow throughout the system without compromising the integrity of the fluid, heating elements and/or vessel. Fluid temperatures are further optimized through the use of OFT (optimized film temperature) technology in the heating elements. These, coupled together, provide an accelerated heat transfer rate, allowing the vessel to perform consistently at shorter lengths, or smaller shell diameters. In addition, the OPTIMAX can be designed for backwards compatibility with existing designs.

Watlow’s has validated these technologies through CFD/FEA modeling, as well as over 5000 hours of laboratory testing.
