ViscoLine Multitube Unit Series

ViscoLine Multitube heat exchangers are used in conjunction with a wide range of products, including milk, cream water, yellow fats, whole egg, egg white, egg yolk, fruit puree, baby food, many kind of fruit juices containing pulp and fibers, fruit concentrates, beer mash, tomato juice and nectar, protein solutions, yeast and soft drinks.

The ViscoLine Multitube unit consists of a bundle of tubes mounted inside an outer shell, and welded onto tube plates at both ends. The product medium flows inside these tubes, and the service medium between and around them. . All the product tubes are connected in parallel and in such a way that the flow is counter-current in relation to the service medium. If required, these product tubes can feature a corrugated surface. Otherwise the inner tubes would be smooth and designed particularly for fouling or viscous fluids. The service media shell could be either smooth or corrugated. . The eccentric reducers can be welded, clamped or flanged. . ViscoLine Multitube modules are normally connected in series and grouped on a common frame. The installation is maintenance free, thus eliminating any need for spare parts.

Technical data The Viscoline Multitube Unit is designed for a pressure of 15 bar (217 PSI) on the product side (tubes) and 10 bar (145 PSI) on the service side (shell), depending on the connections. The unit can, however, accommodate higher pressure ratings, depending on component thickness as connection type. Connections for both product side (tubes) and service side (shell) include: SMS, DIN 11851, DIN 11864, Tri-Clamps, Flange and others. The ViscoLine Multitube unit complies with the European Pressure Equipment Directive (PED 2014/68/EU), and is entitled to bear the CE mark. Where the CE mark is not required, Viscoline would be manufactured according to Sound Engineering Practice (SEP) and Good Manufacturing Practise (GMP, EC 2023/2006). Other design codes are available as well such as ASME VIII Div.1 and others would beon request like SELO’s China Manufacturer License (SELO approval). It is designed to operate at a temperature of 190°C (374°F) although higher temperatures are also met. . All units can be provided with an expansion joint to absorb thermal expansion stress.
