​In the world of high-value cold chain logistics, a refrigerated sea freight container is far more than a "cold box." It is a sophisticated piece of engineering that stands between a successful delivery and a total loss of cargo.

For logistics managers and global shippers, the stakes are high. The primary concerns remain consistent: Is the equipment durable enough for the ocean? Can we control temperature risks? Is there a system for traceability? TLS addresses these critical pain points through specialized engineering and proactive operational support. Here is how we are redefining efficiency and reliability in maritime cold chain projects.

Beyond Basic Cooling: Engineering for Marine Extremes
Standard refrigeration often fails when faced with the harsh realities of sea transit. TLS refrigerated containers are engineered specifically for long-term marine operation. We focus on the structural integrity of the container and superior insulation performance to ensure that external heat gain is minimized.

Our designs are stress-tested to handle continuous vibration, heavy stacking, and the corrosive effects of salt-laden environments. By prioritizing durability at the manufacturing stage, TLS ensures that the unit remains operational under conditions that would cause standard equipment to falter.

Solving the Airflow Puzzle: Reducing Temperature Deviations
A common misconception in the cold chain is that temperature fluctuations are always the fault of the refrigeration unit. In reality, poor airflow and improper cargo arrangement are often the culprits.

TLS incorporates advanced airflow dynamics into our container designs. We don't just provide the hardware; we provide the operational guidance necessary to optimize cargo loading. By ensuring that air circulates effectively around every pallet, we help clients minimize "hot spots" and reduce the risk of spoilage from the very start of the journey.

Real-Time Monitoring and Data Traceability
For temperature-sensitive cargo—such as pharmaceuticals or premium perishables—blind spots are unacceptable. TLS integrates advanced monitoring interfaces and data logging systems into our units.

These systems provide real-time visibility into the container’s internal environment. This traceability is essential for quality assurance, allowing shippers to provide documented proof of temperature stability throughout the voyage. In the event of a dispute or a customs inspection, this actionable data becomes your most valuable asset.

Reliability Through Proven Technology and Maintenance
At TLS, we prioritize long-term reliability over experimental features. We utilize proven refrigeration units and optimize electrical configurations to ensure steady performance.

To prevent mid-voyage equipment failure, we provide clear, comprehensive maintenance instructions and technical support. By focusing on maintainability, we ensure that even when a unit requires service, the process is straightforward, reducing downtime and protecting the integrity of the shipment.

Proactive Risk Management: Pre-Shipping and Operational Boundaries
Reliability starts before the container even reaches the port. TLS defines clear operational parameters and usage limits during the project planning phase, ensuring that the equipment is perfectly matched to the cargo’s specific requirements.

Furthermore, we assist clients with rigorous pre-shipping inspections. Our detailed handover standards and technical instructions act as a final safety net, ensuring that every container is fully operational and "sea-ready" before it is loaded.

Conclusion: A Partner in Cold Chain Excellence
High-performance cold chain transport requires more than just a machine; it requires a strategy. Through superior engineering, airflow optimization, and digital traceability, TLS provides the tools and the confidence needed to move high-value goods across the globe.

​In the demanding world of offshore operations, maintaining the integrity of temperature-sensitive cargo isn't just a requirement—it’s a mission-critical necessity. Whether you are transporting fresh produce, dairy, or essential meat supplies to a remote rig, the equipment you choose must withstand the harshest marine environments while keeping its contents in perfect condition.

TLS, a global leader in containerized solutions with over 30 years of experience, provides high-standard offshore refrigerated (reefer) containers designed specifically to meet these challenges.

Engineered for the Toughest Conditions
Offshore environments are unforgiving, but TLS reefers are built to endure. Every unit is manufactured according to strict DNV 2.7-1 and EN12079 standards, ensuring they are certified for safe lifting and transport in open seas.

To combat the corrosive nature of salt air and ensure a long service life, the outer panels are constructed from muffler-grade stainless steel. This choice of material offers high-grade protection, while the high insulation properties ensure that internal temperatures remain stable regardless of the external weather.

Precision Temperature Control
Precision is at the heart of the TLS refrigerated solution. Equipped with industry-leading refrigeration units from Daikin, Carrier, or Thermo King, these containers can maintain internal temperatures ranging from -20°C to +25°C.

The cooling process is powered by an advanced air duct system that circulates chilled or frozen air throughout the cargo before returning it to the refrigeration unit. To protect "living" products like fruits and vegetables, the units feature adjustable ventilation holes. This fresh air exchange (adjustable from 0-285m³/h) helps exclude warm, toxic air produced by the cargo, effectively preventing spoilage during long-distance transit.

Versatile and User-Friendly Design
TLS understands that deck space and operational efficiency are at a premium offshore. Our reefer containers are designed with several key features to streamline logistics:
  • Size Options: Units are available in 10ft, 20ft, and 40ft configurations, all of which comply with ISO sizes and CSC regulations for seamless intermodal transportation.
  • Ease of Handling: Each unit is fitted with integrated forklift pockets for easy loading and unloading, and all units are fully stackable to save valuable space on ships or in yards.
  • Hygienic and Safe: The interiors are designed to be easy to clean and hygienic. For added safety, customers can opt for specialized additions such as man-trap alarms, door curtains, shelving, and lashing rings.
  • Digital Monitoring: An integrated electronic control panel allows for easy monitoring and adjustment of the container's internal environment.

Global Reach, Local Support
With a head office in Singapore and major hubs in China and the UAE, TLS is positioned to help you wherever you are in the world. Our commitment is to provide the most cost-effective, highest-standard offshore container solutions to the global market.
