Where we deliver results
Every industry has its own needs – here’s how we meet them.
Reefer Container Terminals & Vessels
Terminal operators often lack end-to-end visibility across the cold chain—yet they’re at the center of it all, tasked with keeping cargo within strict temperature thresholds.
How we deliver: RTE’s automated reefer monitoring solutions reduce loss claims, boost energy efficiency, and deliver measurable value to terminal operators.
Pharmaceuticals & Life Science
From clinical labs to pharmacy shelves, pharmaceutical products demand precise, compliant handling. Accurate data ensures safety, meets regulations, and protects patient trust.
How we deliver: RTE’s single and multi-use temperature loggers provide real-time insight into any excursions that could compromise quality.
Cold Storage / Warehousing
From small refrigeration units to massive cold warehouses, temperature fluctuations can threaten product integrity and compliance.
Developing next‑generation solutions: RTE is building next‑generation tools for cold‑storage visibility — our team can guide you on what’s coming and how it fits your operation.
Agriculture and Grocery
Freshness starts at the source. Farmers, growers, and distributors need visibility to maintain safety and quality from field to fork.
How we deliver: RTE ensures reliable tracking of temperature excursions across the supply chain—so perishables arrive just as fresh as when they left.
Real-time Mobile Monitoring
Temperature-sensitive cargo faces risks from departure to delivery—whether it’s traveling by road, air, or sea. Maintaining stable conditions is essential to safeguard quality, satisfy regulators, and build trust.
Developing next‑generation solutions: Advanced mobile monitoring is on the way — let’s discuss your requirements and keep you ahead of cold‑chain risks.
Refrigerated Trucking Services
Protecting perishables starts with the reefer controller—the heart of your cold chain. Exposed to the elements, these units face heavy wear, and replacements are costly.
How we deliver: With 40+ years of expertise, we remanufacture controllers to like‑new condition, cutting costs without sacrificing performance. Our in‑house sensors exceed OEM standards for reliability and value.

Your Biggest Cold Treatment Vulnerability Isn’t Temperature—It’s Documentation
Cold Treatment exposes every gap in your cold chain. With risks like rejected cargo or re‑exports, “good enough” monitoring isn’t enough. Here’s how technology can close those gaps and deliver the documentation accuracy you need to succeed.
Take Command in ’26 – Positioning for a $28B Reefer Market by 2030
2026 isn’t just another year — it’s the year reefer operators either plug in or get left out. Operators who invest now won’t just keep pace; they’ll own the market by 2030. Let’s break it down.
