SPECTRUM Water heat pump

Heating transition, decarbonisation and climate neutrality are the major challenges of our time. With its new SPECTRUM Water heat pump, ENGIE Refrigeration offers an innovative solution that reliably assists users in these endeavours. The oil-free and highly efficient water-water heat pump will take your heating supply to the next level – and that’s guaranteed.

The benefits of the SPECTRUM Water heat pump at a glance

as an ecologically sustainable alternative to heat generators run on fossil fuels
Highly efficient
thanks to a unique combination of turbo compressors with magnetic bearing, flooded shell and tube condensers, and the open-flash economizer
with high-end technology ‘made in Germany’
for rated thermal outputs of 350 to 3,100 kW and condenser leaving water temperatures of up to +65 degrees Celsius
for low-maintenance, reliable and always highly efficient system operation
due to the use of refrigerants with a lower global warming potential (GWP)
Eligible for subsidies
thanks to attractive subsidy programmes from the European Union, the federal government and the states

‘Thanks to the SPECTRUM Water heat pump, users can prepare their heating supply for the future. With our new model they contribute to the decarbonisation of heating and achieve their own climate protection targets. This way, we contribute together to the heating transition and to the 1.5 degree target.’

Future-proof investment: SPECTRUM Water heat pump

Fully in line with the European Green Deal: our SPECTRUM Water heat pump will further the decarbonisation of heating – and thereby contribute towards the heating transition and help you achieve your own climate protection targets.

The SPECTRUM is the ecologically sustainable alternative to heat generators run on fossil fuels and ideal for green building architecture, as well as for forward-looking local authorities and cities. Potential sources of heat include groundwater, seawater, river water, deep geothermal energy, and waste heat from industrial processes and server rooms. This will bring you, the user, a good step closer to your target of climate neutrality. Especially if the compressor runs on green electricity from renewable energies – in combination with the permanently technically tight system design, this enables carbon-neutral operation.

Numbering twelve basic models in total, the SPECTRUM Water heat pump is available with a rated heating capacity of 350 to 3,100 kilowatts, and for condenser leaving water temperatures of up to +65 degrees Celsius.

Operating companies can choose between the R-1234ze A2L low-GWP refrigerants and the high-efficiency A1 safety refrigerants R-515B, R-513A and R-134a. As with the QUANTUM series, an extensive package of options and accessories will also be available. And our modular condenser design ensures that our machines can be flexibly and perfectly adapted to the feed and return levels on your premises. This means that ENGIE Refrigeration is certain to provide the perfect model design for your individual needs.

It’s hardly a secret that energy efficiency always comes first for ENGIE Refrigeration. And of course that applies to the SPECTRUM Water heat pump as well: the new highly condensing, oil-free turbo compressor technology with magnetic bearings combined with flooded shell and tube condensers and the open-flash economizer integrated as standard guarantees maximum seasonal efficiency and performance with a minimal footprint.

Another benefit: instead of being provided by a single compressor, overall capacity is split among multiple compressors, which creates redundancies that ensure maximum operational reliability.

The SPECTRUM Water heat pump is operated without oil. This ensures stable performance and efficiency throughout the machine’s service life, as no oil deposits can develop in the heat exchangers or in the refrigerant circuit. It also makes for a simple and low-maintenance machine design, as no oil management peripherals are required.

In addition, you don’t need to provide oil receptacles on site – and there is no need for labour-intensive oil changes on the compressor. This means that service deployments take less time, so you save time and money in the long term. 

Everything hinges on the foundation. That is why our SPECTRUM Water heat pump is based on the unique concept of the QUANTUM Water – which in turn has been setting the standard as the most efficient water-cooled chiller on the international market since June 2021.

Accordingly, the SPECTRUM also features innovative high-quality technological components: the brains of the machine are provided by an intelligent and fast Siemens S7 PLC. To increase user-friendliness and serviceability, it will be possible to operate the machine via a 10-inch or 15-inch touch panel, in addition to the simple and intuitive operation on a mobile end device via smart control. Further highlights offered by the SPECTRUM Water: the interface with our CoolCare remote maintenance software, and a lead and follower machine PLC integrated as standard.

The SPECTRUM Water heat pump will allow you to benefit from attractive subsidies in future. Because of its very high energy efficiency in heating mode, the system exceeds the requirements of the Ecodesign Directive by a multiple. It also easily achieves the minimum efficiency values stipulated by the federal fund for efficient buildings (BEG), which means that retroactive installation of the heat pump for room heating and warm water preparation in existing non-residential buildings is eligible for subsidies covering up to 40 per cent of eligible costs as an individual measure.

The European Union, the German government and the state governments also offer further lucrative support programmes that financially reward the installation of efficient heat pumps in various areas and for various applications.

If you want to know more about available support for your application, we are happy to advise you!

Outstanding power density, operational reliability, energy efficiency and sustainability: thanks to its specific features, the SPECTRUM Water heat pump is perfect for a variety of applications and many different industries. One thing is certain – the SPECTRUM Water provides maximum efficiency and shrinks your carbon footprint. This means the heat pump is a secure investment in the future.

It is perfect for the following, for example:

  • Provision of low-temperature process heat for industry
