Applications and Industries

Our ISO freezer shipping containers are versatile products with a variety of potential applications:

  • Fish and shellfish: Commercial fisheries around the world rely on our sea freezer units to bring products safely to market without compromising quality or freshness. Our portable blast freezer brings packaged, filleted, or whole fish to temperatures as low as -60ºC (-76ºF). Doing so quickly is critical to preventing damage. By optimizing airflow in the unit, the freezing process is expedited, leading to a more saleable product and less risk overall as fish move through a global supply chain and onto diners’ plates. Our freezer containers are suitable for use with everything from prize Bluefin tuna to sardines and filleted fish, as well as packaged shellfish, cephalopods, and other products.
  • Meat and poultry: Meat and poultry must be kept cold or frozen during transit to prevent the growth of bacteria and foodborne pathogens. Transporting meat and poultry is arguably more complicated than fish, as different products — and different supply chains — have different temperature requirements. For example, prime-grade beef meat may move from the slaughterhouse to market in a matter of days, and may only require cooling to stay fresh. Commercial frozen or processed food products, on the other hand, can spend weeks in transit. What is critical in both scenarios is that temperatures remain stable and predictable. For this reason, Klinge Corporation freezer units play a vital role in shipping meat and poultry around the world.
  • Other frozen foods: Other frozen food includes ice cream and desserts, fruits and berries, packaged meals and pizzas, and more. Spend a few minutes in any grocery store, and you’ll immediately see the variety and diversity of products that are shipped and sold frozen. The Food Safety Modernization Act outlines temperature standards for transporting frozen foods. As well, different frozen foods also have different shelf lives — for example, pork and fatty fish products experience a significant drop-off in quality after six months in frozen storage. Packaged chicken and citrus fruit concentrate, on the other hand, can last for a year or longer.
  • Chemicals and pharmaceuticals: Our freezer containers aren’t just for frozen food transport. They also play an important role in the chemical and pharmaceutical industries, or any other application in which sensitive products must be kept in freezing temperatures. Certain vaccines and other biological products are an excellent example of this. Each year, an estimated 4% of pharmaceutical products are discarded due to problems in the cold chain. Given the health and economic implications of this, any shipping container transporting frozen medical products must be equipped with precise controls and, ideally, dual-redundant freezer systems to prevent failure.

These are just a few of the many uses of our freezer units. With more than 40 years of experience, we excel at matching our customers with the right tools for their operation. Let us help you take the guesswork out of maintaining safe and stable temperatures during shipping. Contact a Klinge Corporation representative to learn more about who we are and how we can help.
