Votator® Origin Series - Scraped Surface Heat Exchangers

Origin Series focuses on application adaptability, configuration flexibility and ease of maintenance for robust and efficient heat transfer.

The Votator® Origin Series is designed for use at 14 to 302°F (-10 to 150°C) with a design pressure of up to 290 psi (20 bar) in the standard version and comes optional in a 362 psi (25 bar) version.

Materials used enable utilization of acidic fluids. The flow-design creates a low pressure drop that enables processing of products with particles and solids.

 

The Votator® Origin is available in three lengths: pilot (5x20), small (5x40), and long (5x80). This flexible range is designed for use not only in production, but also in pilot lab facilities.

 

 

Regardless of your specific application, the multiple Origin options mean a tailor-fit design to your current requirements and is flexible for future processing needs.

The Votator Origin scraped surface heat exchanger is customizable depending on the product, production volume, hygienic requirements, space constraints and heating/cooling medium. Its modular design enables flexible adaptation to your process needs.

To enable process customization with either stainless steel or duplex steel, there are three optional shaft diameters, with a self-loading hinged scraper blade as a standard offering and a floating flat blade for various products including particulates. Additional options include shaft heating, insulation, and double mechanical seals.

The Votator Origin Series complies with 3-A sanitary design and fabrication standards, and available certifications include PED, CE, and CRN. The design is built to EHEDG standards, but a certificate was not pursued.

    • Widely available SIC/SIC sealing surfaces from the SPX FLOW shelf
    • EPDM gaskets

Customization options

  • Product wetted parts in duplex steel (1.4462 / SAF2205)
    • 25 bar option
    • Acidic products
    • Abrasive products
  • Shaft diameter: 112 mm (4.4”) for:
    • better heat transfer
    • shorter contact time with heating surface - less heat exposure to product
    • shorter holding/heating time - less exposure to product
    • less holding volume - less waste product
  • Shaft diameter: 72 mm (2.84”) for:
    • larger particles
    • less pressure drop - smaller pumps

  • Heatable shaft
    • to avoid product build-up when cooling crystallizing products
    • extendable later
  • Two flushable double mechanical seals
    • for aseptic design (use with i.e. aseptic fluids or steam)
    • for use with solidifying or abrasive product particles i.e. sugar (with water flush)
    • single mechanical seals can easily be upgraded
  • Clip-on insulation
    • for easy mounting/dismounting
  • Gasket material: FPM/FKM

Blade selection is based on compatibility with the heat exchanger tube material, product fluid characteristics, processing temperatures, and cost. For the Origin Series, blade selection is also dependent on shaft diameter selection.
