QUANTUM Water chillers

Benefit from high-end technology and discover the new standard for your future refrigeration: the redesigned QUANTUM Water from ENGIE Refrigeration is the most efficient water-cooled chiller series on the market. This is how we help you meet the most stringent economic and ecological requirements for your refrigeration supply – now and in future.

The advantages of the QUANTUM Water at a glance

Most efficient
of all water-cooled chillers on the market
Absolute innovation
through new high-end technology
Outstanding ease of use
with pioneering smart control feature
Maximum safety
thanks to four refrigerants with special enclosure
Shorter delivery times
due to 47 models with a smart modular principle

‘Our redesigned QUANTUM Water incorporates all our experience from 18 years of refrigeration with the existing QUANTUM models. This makes the models in the QUANTUM Water series the most innovative and efficient chillers of their kind that are currently available.’

Rene Giesa, Project Manager Thermodynamics & Mechanics at ENGIE Refrigeration

QUANTUM Water: innovation for the future

47 models
4 refrigerants R-515B, R-134a, R-513A and R-1234ze

  • - 7,300.00 € electricity costs compared to the predecessor model*
  • - 20 t CO2 emissions compared to the predecessor model*
  • - 20 % Refrigerant charge [kg] compared to the predecessor model**


* (Average value of all available models at full load operation with 8,760 operating hours/year).
** (Average value of all available models)

New components, new combination of individual machine components: with the QUANTUM Water you benefit from an innovative combination of technological components that has never existed in this form before. Ultra-modern inner tube technology ensures an excellent heat transfer performance and an especially high level of efficiency with a low input of materials.

But there is more: the QUANTUM Water series is currently the only one on the market where every model is now fitted as standard with an open-flash economizer. Your advantage: even more performance, even greater efficiency. Paired of course with the excellent quality and long service life you know from our chillers.

In future the QUANTUM Water will offer even more intelligent options for control and regulation. We have adapted our tried-and-tested regulation strategy from our QUANTUM Air series to the water-cooled series and deploy the latest Siemens PLC in our switch cabinets ‘made in Germany’. The chillers thus achieve even greater efficiency than their predecessor models, particularly under partial load. All this can considerably reduce your carbon footprint – in line with ‘zero carbon transition as a service’, the mission pursued by ENGIE.

The QUANTUM Water is built for the future. For this reason, the chiller no longer needs to be operated on an integrated touch panel at a defined location on the machine; instead, it can be controlled via a smart control interface (web-based visualisation) – for example, by simply using a tablet and a Wi-Fi connection.

This is a new feature for the refrigeration industry and significantly increases ease of use. At the same time, the innovative smart control feature makes it easier for ENGIE specialists to perform maintenance and service, which saves you, the operating company, time and money in the long term.

Choose between the refrigerants R-515B, R-134a, R-513A and R-1234ze. And regardless of which refrigerant you choose: all QUANTUM Water chillers require a smaller quantity of refrigerant than the predecessor series – another added benefit for greater sustainability.

In addition, a special enclosure guarantees maximum safety, even in the unlikely event of an accident if the A2L refrigerant R-1234ze is used. Due to our special design, the new QUANTUM Water is now suitable for outdoor installation as well; this is unique in the refrigeration market. An ideal solution for all users who lack a large machine room but would nevertheless like to use future-proof high-end technology in their refrigeration supply.

With our sophisticated modular principle, we can offer 47 model versions in total, and you benefit from even shorter delivery times – up to four weeks less than before.

We at ENGIE Refrigeration will work with you to plan the optimal model version for your individual requirements. The advantages? Whether open, hybrid, adiabatic or closed: no matter what re-cooling system is used, the smart modular system offers the most efficient machine for each application. Furthermore, the chiller can be used as a heat pump without changing the hardware.

The new QUANTUM Water is a real powerhouse: the best match of all QUANTUM compressors available on the market ensures maximum performance. All in all, the QUANTUM Water models cover the full spectrum of different capacities, from 200 kilowatts to four megawatts.

They supersede the previous water-cooled QUANTUM W, QUANTUM B, QUANTUM X and QUANTUM G series from ENGIE Refrigeration. The QUANTUM Power will remain available to you as a special solution for even higher performance ranges up to 8.5 megawatts.

One thing is certain: with their specific properties and special advantages, our redesigned QUANTUM Water chillers are perfectly suited for use in a wide range of industries. These include, among others:

  • Data centres
  • Pharmaceutical and chemical industry
  • Hospitals
  • Automotive manufacturers and suppliers
  • Industrial process cooling
  • Technical building services
