Optimax is designed using proprietary enhanced fluid dynamics (EFD) technology to provide advanced flow throughout the system without compromising the integrity of the fluid, heating elements or vessel. According to the manufacturer, tight control of fluid temperatures is achieved through the use of optimized film temperature (OFT) technology in the heating elements. The features combine to provide an accelerated heat transfer rate, allowing the vessel to perform consistently at shorter lengths or smaller shell diameters. Additionally, the exchanger can be designed for backwards compatibility with existing designs.
