Powercool System for water-soluble fluids


  • The Powercool system is the only mist coolant system of its kind. It was designed for water-soluble fluids used on fixed machine tools with coolant inducers or hollow spindles. Powercool lets you apply coolant directly at the tool-work interface. Expanded compressed air cools tooling and helps remove chips from the cutting interface. The mist coolant lubricates flutes, holes and chips to improve hole quality.

    The system operates with a single air supply source at 80-100 psi. Coolant is fed from the supply tank to the control station and then delivered in regulated amounts through to the coolant inlet at the tool or spindle.

    The Powercool system dispenses water-soluble coolants to reduce heat. Water vapor evaporation absorbs heat so tools cool faster. Water-soluble coolants are also used to maintain compatibility with flood coolants used on the same machine.
