Key benefits

  • Boosting thermal performance
  • Saving water
  • Top hygiene control

Boosting thermal performance

  • Pads in front of the finned coil pre-cool air to virtual wet bulb temperature.
  • Up to 40% improved capacity compared to dry cooling.
  • TrilliumSeries coolers consume less energy.
  • TrilliumSeries coolers achieve low process temperatures.
  • Try the cooler with EC motor and improved pre-cooler performance resulting in lower sound levels and 25% lower electrical consumption.

Saving water

  • TrilliumSeries coolers achieve annual water savings exceeding 80% water compared to normal cooling towers by limited adiabatic operation.

Top hygiene control

  • Featuring a once-through system: recirculation and stagnation of water eliminated.
  • No stagnant water: pre-cooler water conveyed from pads to sewer via a gutter.
  • No aerosol formation: TrilliumSeries Coolers minimize the Legionella risk.
  • TrilliumSeries Coolers cool incoming air without transferring water to the dry coil
