Scraped Surface Heat Exchangers

Technical data

Standard unit for high-flexibility and medium viscosity

Product pressure: 20 bar (290 psi); Product wetted parts made of 1,4404 / AISI316L; Rotor diameter: 97 mm (3.8"); PEEK Scraper blades with a self-loading hinged design compatible with the 97 mm (3.8") rotor / shaft diameter; Motor Options: 50Hz 400V motor: 3 kW (4 hp) / 278 rpm/103 Nm (76ft*lb) or 60Hz 460V motor: 2,2 kW (3 hp) / 213 rpm/99 Nm (73ft*lb); Two single mechanical shaft seals: High hygienic demands; Increased run-time and shorter CIP-time for higher production output; The in-cartridge design allows for fast and easy maintenance; Widely available SIC/SIC sealing surfaces; EPDM gaskets

Customization options

Product wetted parts in duplex steel (1.4462 / SAF2205) 25 bar option; Acidic products; Abrasive products; Rotor diameter: 112 mm (4.4”) for: enhanced heat transfer; reduced contact time with heating surface, minimizing heat exposure to the product; shorter holding/heating time, minimizing exposure to the product; less holding volume, minimizing waste product; Rotor diameter: 72 mm (2.84”) for: Handling larger particles; less pressure drop, suitable for smaller pumps; Compatibility with the 72 mm (2.84”), 99 mm (4"), or 112 mm (4.4”) rotor / shaft diameters with a PEEK/PTFE floating scraper blade; 50 Hz / 400V motor: 2.2 kW (3,0 hp) / 176 rpm / 119 Nm (88 ft*lb), 4 kW (5.4 hp) / 142 rpm / 270 Nm (199 ft*lb); 60 Hz / 460V motor: 3 kW (4 hp) / 328 rpm / 87 Nm ( 64 ft*lb), 3.7 kW (5 hp) / 181 rpm / 195 Nm (144 ft*lb); Heatable rotor to prevent product build-up when cooling crystallizing products; can be added later for future needs; Two flushable double mechanical seals for aseptic design (compatible with. aseptic fluids or steam) and; solidifying or abrasive product particles like. sugar (with water flush).; single mechanical seals can easily be upgraded; Clip-on insulation for easy mounting/dismounting; Gasket material: FPM/FKM; The selection of blades is determined by several factors, including compatibility with material of the heat exchanger tube characteristics of the product fluid, processing temperatures and cost considerations. In the case of the Origin Series, the choice of blade selection is also influenced by the selection of rotor diameter.
