The Nitrex closed-loop water cooling system is an add-on to the accelerated cooling option on Nitrex NX and NXH series nitriding/nitrocarburizing furnaces. It’s an external system that provides a controlled, stable supply of clean water to the cooling coils of the furnace’s accelerated cooling internal heat exchanger.


  • Circulates clean water
  • No risk of clogging cooling channels
  • Reduces water consumption, hence reducing utility bills
  • Zero water discharge
  • Reduces risk of corrosion
  • Prolongs longevity of furnace elements
  • Reduces service downtime
