The -70°F Frontier: How Ultra-Cold Logistics Reshapes Food Supply Chains

PLEASANT PRAIRIE, WI – July 17, 2026 – In an unassuming industrial park in Pleasant Prairie, Central Storage & Warehouse (CSW) just switched on a machine that reaches temperatures colder than a winter day on Mars. The grand opening of its new −70°F ultra-cold storage expansion isn't just a local business milestone; it's a critical signal of a profound shift occurring deep within the global food supply chain. While the world became familiar with ultra-cold logistics for mRNA vaccines, CSW is making a strategic bet that the next frontier for this extreme technology lies in what we eat.

This expansion, the second of its kind for the company since 2020, adds highly specialized capacity to an infrastructure network struggling to keep pace with modern demands. It highlights a critical evolution: the 'security-first' mindset, once confined to data and IT, is now the driving force behind the physical logistics that feed the nation. For an industry where temperature variation can mean the difference between profit and peril, mastering the deep freeze is becoming the ultimate competitive advantage.

Engineering an Arctic in the Midwest

Building a stable −70°F (−57°C) environment is a monumental engineering challenge that makes a conventional freezer look like a kitchen appliance. This isn't about simply turning down a thermostat. It involves creating a hermetically sealed ecosystem where every component is purpose-built for extreme-temperature survival. CSW partnered with industry specialists Consolidated Construction Company (CCC) and Summit Refrigeration to execute the project, drawing on a deep well of experience.

CCC, which has partnered with CSW on nearly 20 projects, understands the unique physics of cold. The construction requires specialized insulated panels to prevent thermal bridging, sophisticated vapor barriers to eliminate even the slightest moisture that would instantly turn to destructive ice, and slab heating systems beneath the foundation to stop the ground from freezing and heaving. The refrigeration systems themselves are complex, multi-stage cascades, a far cry from the single-compressor units in standard freezers. Every watt of energy and degree of temperature is monitored in real-time, with redundant power and backup systems standing by to prevent a catastrophic failure.

This level of technical precision is a direct response to a glaring market need. Research shows that over half of the cold storage warehouses in the United States are over 30 years old, built for a different era of food production. These legacy facilities are often inefficient and incapable of meeting the stringent, and increasingly colder, demands of today's food manufacturers. CSW's investment is a deliberate move to build the infrastructure of tomorrow, today.

Fueling the Food Supply Chain's Future

The most pressing question is, why does the food industry need storage at −70°F? The answer lies in the evolving science of food ingredients and manufacturing. This expansion was purpose-built to support highly sensitive ingredients that are critical to modern food production. These can include high-value probiotics, complex enzyme blends, and other biological additives whose efficacy and shelf life are preserved only at ultra-low temperatures. As food science creates more sophisticated, health-oriented products, the logistical chain to support them must evolve in lockstep.

The demand is undeniable. The global cold chain market, valued at over $360 billion in 2025, is projected to surge past $1.1 trillion by 2034. While pharmaceuticals and biologics are a significant driver of the ultra-low temperature segment, food and beverage logistics remain the dominant user of cold storage overall, accounting for nearly two-thirds of U.S. capacity. CSW's expansion sits at the intersection of these powerful trends, providing pharmaceutical-grade temperature control for the food industry.

This investment allows food manufacturers to innovate, secure in the knowledge that a reliable partner can handle their most sensitive and valuable ingredients. It enables longer shelf life, reduces waste, and ultimately ensures the quality and safety of products reaching consumers. It’s a foundational capability that underpins the next generation of food and beverage products.

A Strategic Bet on Regional Dominance

For Central Storage & Warehouse, this expansion is far more than a new service offering; it's a core element of a disciplined growth strategy. Founded in 1947, the company has methodically built its footprint to become the largest independent cold storage provider in Wisconsin and a top-tier operator in North America. This latest project in Pleasant Prairie, strategically located in the vital corridor between Milwaukee and Chicago, reinforces the Midwest's role as the backbone of America's food processing and distribution network.

CSW's strategy is explicitly customer-centric. "The expansion would not have been possible without our frontline team members and leaders living our people-first, team-based, and service-oriented values every day," said Hill Hamrick, Co-CEO of Central Storage & Warehouse. This philosophy is reflected in their business model of "growing in step with its customers," where the company invests proactively to ensure its long-term partners have the capacity to scale. This approach builds deep, resilient partnerships in a market that is often transactional.

This project is part of a broader pattern of aggressive investment, following a 2021 acquisition by Co-CEOs Hamrick and Sam Krieg. Recent expansions at its Caledonia and Wisconsin Rapids facilities have added tens of thousands of pallet positions and dozens of jobs, addressing the acute need for modern logistics infrastructure. By investing in specialized capabilities like ultra-cold storage, CSW is not just competing in the present; it is defining the terms of competition for the future, cementing its position as an indispensable link in the nation's supply chain.
