The Troll Balls with their effective drive mechanism and the slow constant rotation speed ensure a consistent cleaning result with a very low maintenance. They are suitable for different cleaning fluids and across a wide temperature range and offer a compact cleaning solution by minimal moving parts.

The Troll Balls with their effective drive mechanism and the slow constant rotation speed ensure a consistent cleaning result with a very low maintenance.

Advantages

  • Economic flow rates
  • Ball bearing free-increased service life
  • Slow, constant rotation
  • Powerful round jets
  • FDA conform
  • Hygienic and self-cleaning
  • SIP through the nozzle possible
  • Preferred mounting position: vertical down

Operation

Wash fluid drives a simple rotating motor, which drives the rotating ball. All the wash fluid exits the unit through the small number of large holes. The specially designed pattern of holes ensures the high power jets use the minimum amount of wash fluid to deliver optimum performance.

Applications

The Troll Ball is ideal for replacing fixed or rotating spray balls. The high energy, high impact jets provide very effective cleaning. Compact in design, effective in performance, they meet all hygienic design requirements, which makes them highly suitable for the pharmaceutical, and biotech industries as well as food, beverage and other hygiene conscious industries.
