Featuring patent-pending SmartSpray™ technology, the PF2 induced draft counterflow closed-circuit cooling tower optimizes spray coverage to fully wet the coil. According to the manufacturer, the cooling tower is the ideal choice for counterflow unit replacement or expansion projects. It provides a low-energy solution capable of ex-tended hours of dry operation and a low-energy, drop-in replacement for many existing centri-fugal fan units. The PF2 offers the flexibility to operate in evaporative cooling mode to minimize energy usage, or in dry mode for extreme winter conditions. For reduced sound levels, low-sound fan options, whisper-quiet fans, and water silencers are available.
