Modernisation
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.

Extension
Heat for sustainable shrimp farming
With a CTAexklusiv industrial heat pump, the energy supplier AEW Energie AG uses the waste heat from salt production at the Riburg salt mine for the Rheinfelden Rüchi heating network. A major consumer of the heat is the nearby SwissShrimp AG shrimp farm.

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.
