COLD STORES Keep your cool–use nylon
Effi cient cold storage relies on durable fasteners; however, metal components can lead to heat transfer, corrosion, and increased energy costs. Nylon fasteners are emerging as a practical alternative, and here, Julietta Tarrant, Team Leader at Bluemay, makes the case for nylon in industrial refrigeration.

Since nylon is resistant to corrosion, it does not degrade as quickly as metal in cold, humid environments.
old storage installers rely on fasteners to assemble the panels and doors of
industrial freezers and coolers. These fasteners are essential for maintaining the structural integrity of cold rooms, enabling them to withstand substantial operational pressures over time. The materials used for these components can signifi cantly impact the overall effi ciency, durability, and cost-eff ectiveness of refrigeration systems. Traditionally, metal fasteners have been widely used due to their strength and availability. However, they introduce several challenges, the most notable being heat conduction. Metal fasteners create thermal bridges within a coldroom, enabling the transfer of heat between insulated compartments. This forces refrigeration systems to work harder to maintain optimal temperatures, increasing energy consumption and associated costs. Additionally, metal fasteners are prone to corrosion, particularly in environments with frequent exposure to moisture and fl uctuating temperatures. Over time, corrosion compromises the system’s integrity, making maintenance increasingly diffi cult. In contrast, nylon fasteners have emerged as a viable alternative in industrial refrigeration due to their particular physical properties. Nylon is non-conductive, meaning it does not facilitate heat transfer like metal. This characteristic helps minimise thermal bridges, reducing the strain on refrigeration systems and improving overall energy effi ciency. Additionally, nylon is lightweight yet surprisingly strong, making it easy to handle while still providing the necessary durability for industrial applications. It also exhibits excellent resistance to cold temperatures, remaining reliable even in subzero environments. These combined qualities make nylon an ideal choice for fasteners, brackets, and other components that need to maintain their structural integrity over extended periods.

Another signifi cant advantage of nylon fasteners is their insulating properties, which contribute to improved safety in cold storage facilities. Unlike metal, nylon reduces the risk of fi re hazards caused by electrical faults. Many grades of nylon are self-extinguishing, meaning they inhibit the spread of fl ames in the event of an emergency. This additional layer of safety is crucial in industrial settings where electrical equipment operates close to refrigeration units. Beyond energy effi ciency and safety, nylon fasteners also
off er advantages in maintenance and longevity. Since nylon is resistant to corrosion, it does not degrade as quickly as metal in cold, humid environments. This results in lower maintenance requirements and fewer replacement costs over time, making it a cost-eff ective choice for long-term cold storage operations. Overall, the benefi ts of nylon fasteners in industrial
refrigeration are substantial. By reducing thermal conductivity, preventing corrosion, and enhancing safety, nylon off ers a practical solution that improves the effi ciency and reliability of cold storage systems. As industries continue to seek energy- effi cient alternatives, nylon fasteners and brackets are gaining recognition as a preferred choice over traditional metal components.
