with its new nw150l stainless steel heat exchanger plates, kelvion has complemented its range of heat exchanger plates for viscous and particle-containing media by introducing this new product in the lower range.

the nw models have a wider plate gap than do those in the nt series: which allows efficient heat treatment, with only slight pressure drop, of viscous media and of 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 in turn counters fouling.

as a result, the new plates are outstandingly well suited for applications in sugar production, especially for use with thick juice, syrup, and centrifuge run off.

further application areas are in production of bioethanol, in treatment of industrial wastewater, and in petrochemical processes. so-called posloc assembly means that re-assembling the heat exchangers after cleaning or inspection work is easy.

posloc assures optimal centering of the plate pack – which positively affects the service life of the gaskets. the new nw150l 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 great expense.
