Safe and climate-friendly – Chillers with NH₃ for data centres

Their high safety standards make ammonia chillers a reliable and safe solution for cooling data centres. The example of a redundantly designed cooling system for a regional data centre operator shows that high performance and energy efficiency go hand in hand.

Energy-efficient leisure experience at the Silvretta Thermal Baths

The Silvretta Thermal Baths in Ischgl set new standards, both in terms of the experience it offers and in terms of building technology. The construction and its operation should be as energy-efficient and sustainable as possible. CTA’s heat pumps also play an important role.

Sustainable energy supply for historic building

The site of today’s industrial park “The Valley” is located where the legendary Maggi stock cubes were once produced. From autumn 2023, the historic buildings will be sustainably heated and cooled using energy from the air. The key components are four custom-made, reversible chillers/industrial heat pumps.

Complex cooling control for cannabis products

The professional indoor production of CBD hemp flowers requires the precise regulation of temperature and humidity. LMP GmbH in Nunningen therefore uses CTA’s cooling control system. This ensures an optimal climate, day and night, while cooling and dehumidifying the rooms simultaneously.

CO₂-neutral at 2,100 metres above sea level

Can a building at more than 2,000 metres above sea level be heated in a CO₂-neutral way? The Pro Natura Aletsch Centre in Riederalp puts this to the test and proves that it can. Air/water source heat pumps from CTA play a key role in this process. The power comes from a self-powered photovoltaic system.

Propane chillers, each with a 1.2 MW cooling output

Natural refrigerants are on the rise. Whereas ammonia has to date been the main compound used in megawatt refrigeration systems, propane is now also making inroads into the higher-performance segment. This is underlined by the expansion of the energy centre at the Stuecki-Areal in Basel to include two propane refrigeration systems from CTA, each with a cooling capacity of 1.2 MW.

Perfect cooling for innovative cutting-edge research

Perfect cooling for innovative cutting-edge research. Three NH3 chillers (Varimatik) are installed in the Biozentrum Basel.

530kW air source heating capacity for Basel

In 2018, Basel City energy provider IWB installed two custom-made, high-temperature air/water source heat pumps from CTA, with a total heating capacity of 530 kW, in the St Jakob heating network. These replaced a natural gas-powered combined heat and power unit (CHP) and contributed to the further reduction of CO2 emissions from the heat supply in Basel.

Heat from groundwater heats the Champagne district of Biel

Four-fifths of the energy for heating and hot water in the Champagne district of Biel comes from renewable sources. What makes this possible are two high-performance heat pumps from CTA, which feed the district heating network with heat from the groundwater.

CTA provides biting cold on the Jungfraujoch

Every day, up to 5,000 people visit the ice palace on the Jungfraujoch. The heat input, which “heats up” this tourist attraction of pure ice, is correspondingly high. Two new, customised chillers from CTA provide essential cooling for the ice cave and have significantly reduced the energy input required.
