Trefa Continuous Aerating Systems designs and manufactures high-quality continuous process lines for the food and non-food industry. For over sixty years — fully developed and produced in-house in Angerlo, the Netherlands.
The founder of Trefa was one of the inventors of the ‘pin head’ principle, which still forms the basis of every modern aerating machine. That knowledge is in our DNA.
