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 is built for global operations. Through the cloud‑based GRASP platform, operators gain real‑time visibility into every connected reefer — whether it’s plugged in at a terminal or onboard a vessel. This location‑agnostic approach reduces loss claims, improves energy efficiency, and strengthens operational control across distributed teams and sites.
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.
Food Cold-Chain: Production, Distribution & Retail
Freshness starts at the source—and every step matters. Agriculture, producers, packers, distributors, and retail grocery operations all rely on accurate temperature visibility to protect food quality, ensure safety, and maintain compliance from origin to shelf.
How we deliver: RTEL provides clear, defensible tracking of temperature conditions across the entire food cold-chain — helping teams identify excursions, verify product integrity, reduce loss, and support FSMA, HACCP, and 21 CFR Part 11 compliance.
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.
