"It feels really good to utilize the cooling water. We get our heating ‘free of charge’ ", says Technical Manager Svante Björklund.
Carlfors Bruk in Huskvarna, Småland, Sweden, manufacture aluminium powder and aluminium pastes. 98% is exported. Three CTC heat pumps were recently installed to collect and use heat from the cooling water used in the manufacturing process. Previously the heat was wasted in cooling towers.
"The new pumps work very well. They can maintain a comfortable temperature in our new factory," says Svante Björklund.
Heating the factory premises
The factory has existed since 1898, and the three CTC heat pumps are used to heat a new factory next to the main building. The employees are happy that the indoor temperature in the new building always stays above 15 degrees Celsius.
"The old premises, located one kilometre away, were not heated at all," says Svante.
Carlfors Bruk is enjoying steady growth, and the company is very pleased with the investment in heat pumps.
"We are now investigating how we can continue to utilize all our process water," he says.
