LINDAU ON LAKE CONSTANCE, Germany, 14 November 2024: ENGIE Refrigeration said it is expanding its product portfolio through offering its AMONUM Air chillers on the international market from the spring of 2025. Making the announcement through a Press Release, ENGIE claimed the new series of chillers has excellent efficiency values, and features the simultaneous use of Green Heat Recovery (GHR) for heat recovery and the use of the natural refrigerant, ammonia (R-717).

ENGIE said it presented the new AMONUM Air chiller series for the first time at this year’s Chillventa, in October 2024. Jochen Hornung, CEO, ENGIE Refrigeration, said: “AMONUM Air ideally complements our existing portfolio at ENGIE Refrigeration. The chiller series reflects our guiding principle of ‘Excellence in Cooling and Heating’, as it offers outstanding seasonal efficiency and is also very environmentally friendly, thanks to the natural refrigerant, ammonia. This means that we are precisely meeting current demands in the cooling and heating market, as confirmed by the great interest shown by our customers at Chillventa.”

According to ENGIE, the air-cooled AMONUM Air series is “Made in Germany”. It is available on the market with four basic models, with a performance ranging from 400 to 1,500 kilowatts and for outlet temperatures between -15 degrees C and +15 degrees C, ENGIE said.

AMONUM Air is based on the proven technology of the QUANTUM Air chillers from ENGIE Refrigeration and offers the latest E/I&C hardware and software architecture – such as EER Auto Control – in combination with optimally harmonised technology components, ENGIE claimed, adding that as a result, ENGIE Refrigeration specialists achieve very high seasonal efficiency.

The series convinces with maximum system safety and is considered to be technically permanently tight, which is of utmost importance when using the refrigerant ammonia, ENGIE said. Ammonia is a refrigerant without ozone-depleting or global-warming potential and, beyond that, is highly efficient and cost-effective, ENGIE said. The chillers also come with several innovative variants, including the integrated GHR and the new high-temperature GHR, which allows outlet temperatures of up to 70 degrees C, ENGIE said, adding that both features work simultaneously, meaning that users can apply the waste heat simultaneously at two different temperature levels and in two separate hydraulic circuits. Hornung said, “Our new AMONUM Air series meets current and future requirements for both cooling and heating – whether in manufacturing industry, food industry or in building services.
