Modernisation

CO₂ heat pump for a residential complex with 28 homes

At the InSite residential complex in Bassersdorf, a modern CO2 air/water heat pump, supported by an isobutane heat pump, acts as a reliable source of heat and hot water for the 28 homes spread across three buildings. The installation shows how fossil fuel heating systems can be replaced efficiently and sustainably even in large residential complexes.

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.

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.

High-performance air/water

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.

District heating network

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.

Jungfraujoch

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.

Heritage conservation

CTA ensures cool heads in the Northern Federal Parliament building

In the Federal Parliament building in Bern, custom CTA chillers also ensure pleasant room temperatures on hot days. The modern cooling solutions, which were implemented as part of comprehensive redevelopment works, integrate perfectly into the historic building and prove their worth through their operational efficiency and low energy consumption.

University Hospital

Expanding cold generation at the University Hospital of Bern

Hospitals must be able to rely on the safe cooling of equipment and rooms. The University Hospital of Bern, for example, relies on a customised CTA chiller for their expanded cooling system. This operates using the environmentally friendly hydrofluoroolefin (HFO) refrigerant and produces reliable cooling for a number of hospital buildings, with an output of around 1.6 MW.
