Kelvion has added new NW150L stainless steel heat exchanger plates to its range. The NW models have a wider plate gap than the NT series; this allows efficient heat treatment, with only slight pressure drop for viscous media and liquids with particle diameters up to 5 mm. In addition, the extremely wide herringbone plate corrugation, with a gap width of 10 mm, assures highly turbulent flow at all points of the plate, which counters fouling. Application areas include the production of bioethanol, treatment of industrial wastewater, and petrochemical processes.
The PosLoc assembly simplifies assembling the heat exchangers after cleaning or inspection work. PosLoc assures optimal centering of the plate pack, which improves the service life of the gaskets, said the company. The new NW150L plate is compatible with the frames of the extensively used NT150L series. As a result, users with NT150L plates of the same size – which require cleaning more frequently owing to particle fouling – can change to the new plate without incurring significant expense.
