Where to Buy

The Votator II incorporates the most popular features of the Thermutator and Votator lines. The unique hydraulic system on the vertical unit makes inspection easy without the use of tools.


  • No tools required to inspect blades inside unit
  • Unique hydraulic system for easy mutator removal; two units are able to run off of one hydraulic cylinder
  • 3A, ASME, and PED Certified

Single and Double Mechanical Seals


  • Greater material choices for various applications (ceramic, carbon, silicon carbide, and tungsten carbide)
  • Available in standard and narrow faces
  • Ease of maintenance and lower cost of ownership

PEEK™ Blades


  • 100% PEEK™ - no filler or inserts
  • Available in metal detectable version

Integral Gear Motor Drive


  • Gear drive is directly coupled to the mutator shaft eliminating the need for a secondary drive shaft and bearing block.
  • Overall length of heat exchanger is reduced by 20 – 25%.
  • Easy to maintain and self-aligning
  • Available with up to 30 horsepower for handling the most viscous products

Removable Heat Transfer Tube


  • Can be serviced without disturbing hydraulic lifting system, utility piping, or the drive assembly
  • Flange bolted to the jacket on the non-driven end allows for quick removal.
  • Reliable double O-Ring seal on each end eliminates the need for an expansion joint.

Heat Transfer Area


  • Units are available with up to 11 sq ft of heat transfer area (6 X 84)

Blade selection is based on many factors including compatibility with the heat exchanger tube material, product fluid characteristics, processing temperatures, and cost. Metal blades provide the best scraping properties, which means theoretically better heat transfer. However, metal blades are usually the most expensive, must run on a hard chrome surface and must be properly sharpened to avoid damaging the heat transfer tube. Today, with the development of new high temperature and FDA compliant plastic materials, there are alternatives to metal blades. The blade options below provides a wide range of our most popular blades. Many other options are also available.
