Liquid nitrogen tunnel freezer
March 6, 2013
The Air Products Freshline MP liquid nitrogen tunnel freezer achieves cryogenic temperatures throughout the tunnel. A PLC-driven controller operates all functions of the unit, while a touch screen interface provides an information tracking capability. The entire length of the freezer is gasketed to maintain a tight enclosure. Meeting or exceeding international cleanability standards, the freezer has accessible, slightly pitched surfaces that promote water runoff during cleaning.
