Our Vision


It is a great challenge and we are proud to be part of this new technology. We expect that 5-7% of the market will ultimately choose this method of freezing.

AEF is the first company in the world to focus on freezing food, instead of just producing cold. There is a big difference in how we approach it, think of the cooking process. Depending on the product, you choose the right technique. Until now, however, there has been only one method for freezing: "close the door of a freezer". Acoustic freezing allows use of different algorithms for different types of food.

In addition to the aforementioned benefits, the AEF technology offers entrepreneurs opportunities to be innovative, develop new products and discover new markets. If you don't want to compromise on the quality of your product after freezing, AEF is definitely the solution!
