Efficient Chillers

Sirus is the agent for ENGIE Refrigeration efficient chillers in Ireland. The oil-free ENGIE QUANTUM chiller with up to seven radial Turbocor Compressors is available in a large number of variants and can be used in a variety of ways.


The various models in the ENGIE QUANTUM series offer impressive solutions for each chilling situation. They can be individually tailored to ensure that every customer gets exactly the refrigeration they need.

These efficient chillers are characterised by their soft start-up, in other words, low start-up currents, as well as their extremely low-noise and low-vibration operation. Moreover, they feature an impressively high power density. This adds up to maximum energy efficiency combined with a small footprint.

Sirus’ refrigeration specialists are on hand from the start to look after every chiller and regularly check their operation to ensure that refrigeration requirements are being optimally met. Our service engineers are “Danfoss Turbocor” trained.

The benefits of ENGIE QUANTUM chillers include:

  • Maximum energy efficiency
  • Oil-free Danfoss Turbocor Compressor
  • No friction losses thanks to contact-free magnetic bearings
  • Significantly lower maintenance costs
  • More efficient heat transfer – not impaired by oil
  • Starts smoothly, then runs quietly and with low vibration
  • Reduced CO₂ emissions
  • High level of safety
  • Absolute operational reliability.
  • The most efficient chillers listed on the SEAI Triple E Register.
ENGIE Water-cooled QUANTUM Chiller

Water-cooled QUANTUM-Series Efficient Chiller

The water-cooled QUANTUM works just as well for process cooling with its high demands for reliability, as for HVAC applications that present a special challenge to produce efficient refrigeration that does not affect the climate.

ENGIE Air-cooled QUANTUM Chiller

Air-cooled QUANTUM-Series Efficient Chiller

The QUANTUM is also available as an air-cooled variation to be set up outdoors. This technology is independent of external re-cooling. It can be placed where no cooling water is available.

Danfoss Turbocor Compressor

Danfoss Turbocor compressors use advanced technology to deliver high efficiency and low sound levels in a compact footprint.

Industry-leading performance is achieved by using oil-free, magnetic bearings that provide world-class efficiency and zero performance degradation over the life of the compressor.  Permanent magnet motors and variable speed drives provide unmatched full and part load efficiency.
