Arneg Cold Ring System

Glycol technology for large systems


Thanks to our Arneg Cold Ring solution, a circuit fed with low temperature, low pressure water refrigerates every element in your system. Water, with glycol anti-freeze added at low pressure (2 bar), is cooled to the ideal temperature inside the unit by a chiller consisting of:

  • Condenser
  • Compressor
  • Cold glycol pump

This modular and easy to install solution is ideal for normal temperature cabinets (including those with Arneg Air System technology).

Even maintenance of the cabinet is easy and effective. Any leaks from the circuit are detected immediately by a pressure drop in the water circuit and by the presence of colourant in the mix.

The refrigerant circuit can be charged with HFC (R448A, R449A) or low-GWP HFO gas. On request, Arneg can also supply a low-charge R290 propane solution.

90% less gas charge than conventional systems
Use of the most ecologically sustainable refrigerants
Safe, modular solution
Easy installation and operation
