Refrigerated trailers, commonly known as reefers, are integral to the transportation of perishable goods, ensuring products remain at optimal temperatures throughout transit. In 2024, the refrigerated trailer market in North America was valued at approximately $6.52 billion, reflecting the role these units play in the supply chain. Given their extensive use—often exceeding a million miles over approximately seven years—these trailers are susceptible to wear and tear, particularly on interior walls due to factors like forklift mishaps, load shifts, and moisture-induced delamination. Efficient and timely repairs are essential to maintain their functionality and minimize operational downtime and keep the supply chain humming.
Advancements in Reefer Trailer Wall Repairs
Traditionally, repairing the interior walls of refrigerated trailers was a time-consuming process. Conventional methods involve the use of mastic adhesives, which require prolonged curing times of 24 to 48 hours. This necessitated the use of blocking and bracing techniques—employing load bars and wooden supports—to maintain pressure on the repaired sections during the curing period. Such methods extended the trailer's downtime and also posed safety risks during the repair process.
The Role of Spray Adhesives in Accelerating Repairs
The introduction of advanced spray adhesives has revolutionized the repair process for reefer trailer walls. Products like TensorGrip® EP0-CA have been specifically designed for refrigerated trailer repairs, offering significant advantages over traditional adhesives. These spray adhesives provide rapid curing times, achieving approximately 80% of their final strength immediately upon application and full strength within 24 hours. This immediate bond eliminates the need for blocking and bracing, thereby reducing both the labor involved and potential safety hazards.
Quantifiable Benefits: Time and Cost Savings
The adoption of spray adhesives translates to substantial time and cost savings. For instance, with TensorGrip® EP0-CAL Low-Odor Low-VOC Reefer Repair Adhesive, a full wall repair can be completed in approximately 45 minutes, a stark contrast to the 24-hour curing period required by traditional methods. This reduction in repair time allows trailers to return to service more swiftly, enhancing fleet utilization and profitability. Moreover, the elimination of blocking and bracing reduces labor costs and minimizes the risk of damage during the curing process.
Challenges Faced by Reefer Trailer Repair Shops
Reefer trailer repair shops encounter several challenges in their operations:
- Complexity of Repairs: Refrigerated trailers comprise intricate systems, including insulation, refrigeration units, and specialized flooring. Addressing issues such as fluid and refrigerant leaks, faulty belts and hoses, and damaged air chutes requires specialized knowledge and skills.
- Regulatory Compliance: Adhering to stringent industry regulations is paramount. Repair shops must ensure that all repairs meet safety and quality standards to maintain the integrity of temperature-sensitive cargo. Non-compliance can lead to legal repercussions and damage to reputation.
- Supply Chain Disruptions: Sourcing specialized parts and materials for refrigerated trailers can be challenging, especially during global supply chain disruptions. Delays in obtaining necessary components can extend repair times and increase costs.
Incorporating spray adhesives into refrigerated trailer wall repairs offers a more efficient, safer, and cost-effective solution. By significantly reducing repair times and associated labor costs, these advanced adhesives ensure that trailers are back on the road promptly, maintaining the integrity of temperature-sensitive cargo and optimizing fleet operations. However, repair shops must navigate challenges such as the complexity of repairs, regulatory compliance, and supply chain disruptions to maintain high service standards. Tensorgrip EP0 Spray Adhesives are a complete line of adhesive solutions to help simplify running a reefer repair shop and keep the distribution and supply chain running smoothly.
