VT / HT Origin Series - Scraped Surface Heat Exchangers

No matter your specific application, the multiple Origin options provide a customized design that perfectly fits your current requirements and remains adaptable for future processing needs.

The APV VT / HT Origin scraped surface heat exchanger offers flexibility based on your product, production volume, hygienic requirements, space constraints and heating/cooling medium. Its modular design allows for easy adjustment to meet your process needs.

For process customization, you can choose between stainless steel or duplex steel and there are three optional rotor diameters available. The standard offering includes a self-loading hinged scraper blade, while a floating flat blade is suitable for various products, including those with particulates. Additional options include rotor heating, insulation and double mechanical seals.

The APV VT / HT Origin Series adheres to 3-A sanitary design and fabrication standards and is certified for PED, CE and CRN compliance. The design is built to EHEDG standards although a certificate was not pursued.

  • 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

• 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.
