International Commissioning of NH₃ & Freon Systems

Industrial refrigeration systems require in-depth technical expertise, experience with complex systems, and absolute safety competence. Our focus is on stable, energy-efficient, and safe plant operation—from the initial start-up to final acceptance.

  • Site inspection, pressure and leak testing
  • Evacuation and charging with NH₃ or synthetic refrigerants (HFC/HFO)
  • System adjustment, load testing and performance verification
  • ⁠Documentation and technical acceptance
  • Supply of spare parts and components — manufacturer-independent and available at short notice
