In many clinics, doctors and nurses are working heroically for our health. This is something we have all become strongly aware of in the current corona pandemic. And because nothing can be left to chance in medical facilities, reliable refrigeration is essential. Around the world, ENGIE Refrigeration is helping to ensure that doctors and nurses can count on stable processes: our QUANTUM chillers provide reliable refrigeration for more than 150 hospitals worldwide.
What role does refrigeration play for hospitals? As a matter of fact, refrigeration is absolutely critical for medical facilities. Hospitals contain many medical devices and systems that can only function properly at the right temperature – from medical gases, MRI and CT devices and sterilisers to the media supply for operating theatres. Of course all operating theatres, intensive care units and clean rooms must always have exactly the right temperature. It is also important that chillers are as quiet as possible. This is because a hospital is a place of healing, and constant noise is an additional strain on the well-being of patients, while also distracting hospital staff. A good indoor environment in the operating theatre and the wards also contributes towards optimal treatment and helps patients heal quickly. So it is hardly surprising that clinics set especially high standards for their refrigeration supply.
ENGIE specialises in exactly these kinds of sensitive applications. We have more than ten years of experience in the field of refrigeration for hospitals. From Germany to Iran, from the UK to La Réunion, more than 150 hospitals and clinics around the world now rely on QUANTUM chillers. That is because these chillers offer many important benefits: first, QUANTUM chillers guarantee maximum energy efficiency and absolute reliability. They also feature gentle starting behaviour – i.e. low start-up currents – and high performance density – in other words, maximum energy efficiency combined with a small footprint. In addition, they are quiet, with low vibration levels, and can be operated in an exceedingly low-wear manner; this is a considerable additional benefit, as it reduces maintenance and operating costs. At the same time, the ability to change compressors while the systems are running ensures that those systems are constantly available and highly reliable – and thus contributes towards dependable processes at medical facilities.
The Schoen Clinic, with locations in Hamburg, Bad Aibling, and Vogtareuth in the Chiemgau region, is one of the companies to benefit from such a reliable refrigeration supply – and has been for many years. The clinic in Vogtareuth has been relying on refrigeration technology from ENGIE since 2010. Today it operates three especially quiet and low-vibration QUANTUM chillers. Only one of the machines is in constant operation, while the others are added when necessary. This ensures a refrigeration supply around the clock. And it does so throughout the clinic, which treats around 16,000 patients from around the world every year.
Refrigeration is no less important in other parts of the world – such as Sydney, some 16,000 kilometres away. QUANTUM chillers from ENGIE have been installed there as well. At Liverpool Hospital, one of the largest clinics in New South Wales and one of the leading trauma centres in Australia, they provide a whole lot of power. Eight water-cooled QUANTUM chillers with a refrigeration capacity of ten megawatts guarantee ideal temperatures for all processes at the clinic. They are especially eco-friendly, as they use R-1234ze as their refrigerant. This refrigerant has a global warming potential (GWP) of less than 1, and thus comfortably meets the requirements of the F-gas Regulation and the Ecodesign Directive. Liverpool Hospital is currently home to the world’s largest connected chiller park with this refrigerant. Oil-free and especially energy-efficient in operation, the chillers thus minimise the ecological footprint of the clinic on the outskirts of Sydney – and ensure that the refrigeration supply is always secure, so our heroes can work in optimal conditions.
Climate-friendly QUANTUM chiller of the new generation with refrigerant R-1324ze supplements a hospital´s cooling supply.

Optimal energy efficiency for hospitals: The heat pump will guarantee the combined generation of cold and heat in parallel to the two new large boilers, generate thermal heat for heating drinking water.
The customer's desire for greater energy efficiency was at the heart of ENGIE Refrigeration's refrigeration concept. The solution is called QUANTUM, because the high energy efficiency at partial load is particularly convincing. In the Schön Klinik Vogtareuth, one QUANTUM chiller runs in regular operation, and another one is switched on as needed.
Digitisation is one of the economic megatrends of our age. Most businesses are reliant on smooth-running information technology (IT) – and thus on data centres, the IT all-rounder. But how can a sensitive digital infrastructure be operated as safely, efficiently and sustainably as possible? With its QUANTUM chiller and SPECTRUM heat pump, ENGIE Refrigeration now takes care of ten local data centres belonging to a German provider – and is breaking new ground for the IT industry in the process.
Due to their environmental impact, refrigeration systems and heat pumps have faced increased scrutiny from environmental organisations, governments and the public for some time. Debate has centred on the greenhouse effect of refrigerants, not least because of planned amendments to the F-Gas Regulation, which will make it more stringent. However, the climate relevance of chillers and heat pumps can only be properly assessed with the help of an ecological balance sheet that includes the entire greenhouse effect of the systems. One popular method of holistic ecological assessment is provided by the TEWI value.
The digital transformation is opening up a wealth of new opportunities for companies. Augmented reality (AR) in particular is providing innovative momentum to Industry 4.0 and making complex processes significantly more efficient. ENGIE Refrigeration has long recognised the potential of this technology for the refrigeration and heating industry and has been working together with the global AR/VR technology leader HOLO-LIGHT since 2017 to integrate AR applications into individual work areas. Jannick Hartmann, Senior Software Sales Manager at HOLO-LIGHT, and Jörn Stiegelmeier, Head of Technology and Development at ENGIE Refrigeration, talk about the benefits of augmented reality for both employees and customers.
There are many chillers, but SPECTRUM Water only exists once. The model is unique in its performance range – this is ensured by the sophisticated product features. What precise added value does this offer to users?
The heating transition starts in buildings. This means that cities and municipalities, with their large number of buildings, play a crucial role on the path to carbon neutrality. What’s the best way to structure the energy transition and heating transition as soon as possible and as successfully as possible? Large heat pumps such as the SPECTRUM Water and thermeco2 can make an important contribution to this endeavour
