plate heat exchangers

z - zb Applications: thermal exchange

ApplicationsThe Zilmet plate heat exchanger has many applications. These include : production of sanitary hot water, de-coupling of thermal circuits, district heating systems, recovery of heat coming from industrial process, cooling or heating of alimentary fluids (milk, beer, wine, ...), cooling of industrial machineries, heating of water for swimming-pools, solar systems.

AdvantagesIn every situation which requires a thermal exchange between two fluids, the Zilmet plate heat exchanger is the right choice. The high efficiency, the long life, the low price, the small dimensions, the high modularity, the easy maintenance and the high reliability are some of the most important advantages of Zilmet plate heat exchangers.

PlatesThe plates are manufactured with 316 L stainless steel 0.0197 in thick. This kind of material and thickness allows to have a very good transmission coefficient and to assure a great corrosion resistance.

GasketsZilmet plate heat exchangers are equipped with glued EPDM gaskets, with maximum working temperature 284°F.For particular applications, such as gasoline and oils, they can be equipped on request with nitril glued gaskets, which maximum working temperature is 230°F.

FramesThe frames are manufactured with silver painted carbon steel. The thickness is designed for the respective working pressure.

Tests100% of Zilmet plate heat exchangers are tested before shipment at 1,5 times the maximum working pressure.
