What are stainless steel freezers?

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 for food manufacturers at a time when food-borne bacteria and viruses can threaten the quality of their product.

Our customers are food processing system integrators. Together, we design and build stainless steel freezer enclosures that will meet freezing requirements for a variety of food products. The system integrator is responsible for the complete unit, including process design and procurement of the enclosure (from SFI) plus the internals and controls that convey and freeze the foods within the freezer enclosure. Working together, we develop custom freezing solutions to help the end user produce foods of the highest quality.

Over 100 freezer enclosure installations

SFI has field fabricated more than 120 stainless steel freezer enclosures since building our first unit in 1988. During this time, we have worked with customers to perfect our design, skills and fabrication methods, making us a leading provider of fully welded, stainless steel enclosures.

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.
