Emmi Fondue, Langnau
Emmi Fondue
218 m2 solar field; 0.15 MWth
Langnau, Switzerland
55 to 104ᣞC
Dairy
163 MWhth/y (747 kWh/y/m2)
Process heat
18,821 l/y of heating oil
EPC
49 ton/y of CO2



Challenge
A leading multinational in the dairy industry, Emmi, committed to reduce Scope 1 GHG
emissions in its factories as part of its corporate ESG goals. Solar thermal is required to
supply process heat in a factory producing fondue which has an intermittent daily load profile
and works 5 days per week out of 7.
Solution
TVP integrates the client process hot water circuit with a water-to-water heat exchanger
downstream to a stratified thermal storage tank which act as buffer during week days
smoothing solar energy delivery throughout daylight hours, while storing the thermal energy
during the weekends to be then released on Monday.
