JET Technology's high-efficiency impingement tunnel freezer is designed according to a unique European concept, embodying the precision engineering of a world-class impingement freezer.
Cool airflow flows within the enclosure, and a specially designed air tunnel is in place.
Thousands of high-speed air jets are aimed at both the top and bottom surfaces of the product as it travels along the conveyor of the freezer.
