Freezer Enclosures

Over 100 freezer tunnel installations

SFI has constructed over 100 freezer enclosures in the field since building our first unit in 1988.  During this time we have worked with customers to perfect our design, skills and methods, making us a leading provider of fully welded, stainless steel enclosures.

What is a freezer enclosure?

A freezer enclosure, sometimes called a tunnel, is a very large, insulated, rectangular room-within-a-room.  It is sanitary by design, having fully-welded stainless steel walls, floors and ceilings, making it easy to clean—a must have to food manufacturers at a time when food borne bacteria and viruses can threaten the quality of their product.

We work with food processing system integrators to design and build stainless steel enclosures that will meet freezing requirements for a variety of food products.  The system integrator is responsible for process design and procurement of the internals that convey and freeze the foods within the SFI freezer enclosure.  We work together to develop custom freezing solutions to help our customers deliver the highest quality food products to their customers.

Benefits

There are many benefits to choosing an SFI stainless steel freezer enclosure including:

  • Design allows for complete sanitation in minimal time
  • Fully welded exposed surfaces provide a sanitary environment for freezing
  • Our large radius interior corners are easily cleaned
  • Floors are sloped to drain
  • Freezers are custom designed and fabricated to meet your thermal processing needs
  • There are no bolts, caulking or gaskets in the walls, ceilings or floors that will affect cleaning
  • The double wall enclosure is fully insulated (top, bottom and sides) providing an environment for efficient freezing
  • All interior materials of construction are either stainless steel or synthetics
  • Expansion joints are strategically placed to allow for expansion and contraction due to temperature swings (from freezing to CIP cleaning)
  • Insulated personnel-access doors feature heavy-duty hardware, heat tape, FDA red silicone gaskets and are equipped with an interior safety latch
  • Design can be modified for cooking

Freezer Enclosure Construction Details

  • SFI freezer enclosures are suitable for new construction or our crew will demolish an existing box and replace it with a new SFI freezer enclosure.
  • Freezer enclosures are built on-site by SFI personnel, experienced and skilled in field fabrication of our stainless steel equipment.
  • Doors, roof and wall sections are pre-fabricated in our Springfield, Missouri facility prior to shipping to the field resulting in less time on-site.
