WRA Vertical

Air cooled industrial chiller

Air cooled industrial chiller

WRA units are compact industrial chillers, ideal for cooling water or process fluids, designed to provide the high standards of reliability required for 24/7 production processes.

Thanks to the standard non-ferrous hydraulic circuit and the wide range of options and accessories, WRAs are successfully used for cooling in a number of applications, such as:

  • machine tools
  • chip cutting machines
  • laser
  • wood processing machines
  • glueing machines
  • automotive
  • food & beverage
  • plastic

Reliability and the ability to adapt to specific plant requirements are the determining factors, which allow WRA liquid chillers to respond perfectly to the needs of these industrial applications, guaranteeing continuity of production and contributing to a reduction in operating costs.
