Lower operating cost


The QUANTUM series of high capacity chillers offer impressive solutions for each refrigeration application and can be individually tailored to ensure that every customer gets exactly the refrigeration they require. Liquid-cooled oil-free turbo chillers for inside installation.

Delivered fully pre-assembled and filled with refrigerant. Manufactured as a compact modular unit in line with the following standards: 2014/68/EU, 2006/42/EC, EN ISO 12100, EN 378-2.

The Quantum chiller range is available in either water cooled or air-cooled versions. 50% Lower operating costs:

  • High-efficiency compressors > no friction losses thanks to magnetic bearings
  • Each compressor is fitted with a frequency converter > maximum efficiency during partial load
  • Heat exchangers with high-performance ribbed pipes > optimum heat transfer with minimum pressure loss.
Water Cooled

Water Cooled

The water-cooled QUANTUM was developed for process cooling in HVAC applications where efficient refrigeration is required despite the climate.

IWC offer various water cooling tower solutions ranging from counter flow to crossflow configurations, in either forced or induced draught.


  • Maximum energy efficiency
  • Soft start up
  • Minimal noise and vibration
  • Reduced CO2 emissions
  • Operational safety
Air Cooled

Air Cooled

At 2 megawatts, it is the most powerful air-cooled chiller of its type on the international market – and it works more intelligently than all other models currently available: the new QUANTUM Air.


  • Energy-efficient and environmentally friendly
  • Minimal noise
  • Lightweight and compact
  • Suitable for numerous areas, e.g. data centres, hospitals or office building
