In the ever-changing and challenging industrial environment, product quality has always been the cornerstone of customer trust. From offshore wind power platforms to desert energy bases, from hazardous areas in chemical plants to accommodation spaces on ocean-going vessels—every customized TLS functional container is a reliability-focused product born under strict quality control.

At TLS, we understand that true quality is not just the “Pass” label at the final inspection stage, but a commitment embedded in every step of the process—starting from the moment a steel plate enters our facility, through every stage of production, with meticulous attention to detail and accountability.

1. Rigorous Material Selection: Quality Control from the Source
Every TLS functional container starts with carefully selected materials:
  • Steel Structure Materials: Compliant with international standards (e.g., EN10204, ASTM), complete with material certificates and traceable identification numbers.
  • Electrical and Fan Components: Sourced from reputable suppliers with CE/UL certification.
  • Special-Purpose Containers: For example, Zone 1/Zone 2 positive pressure explosion-proof containers require certification and verification for explosion-proof electrical components, sealing elements, and fireproof insulation materials.
All incoming materials are subject to physical inspection—dimensions, thickness, and material identification—along with document verification. Any non-conforming materials are rejected and re-procured.

2. Structural Fabrication
Welding Quality Control
  • Welders must hold valid welding certifications.
  • All main load-bearing structure welds undergo non-destructive testing (e.g., ultrasonic testing UT or radiographic testing RT).
Any welds that fail to meet standards are repaired until compliant.

Sheet Metal and Cutouts
  • Fabrication strictly follows design drawings; all embedded components, cable entries, and equipment mounting panels must have dimensions and elevations verified.
  • Multi-step cross-check inspections ensure installation accuracy.

3. Electrical and System Installation: Functional Safety Verification
Cable Installation and Identification
  • Cables are laid according to electrical design drawings, with identification tags at both ends of every cable.
  • Terminal blocks, cable trays, and socket positions are verified by quality inspectors.

System Commissioning
  • Positive pressure system fan performance, air exchange rate, and pressure retention time are fully tested and recorded.
  • For energy storage containers, BMS linkage simulation and battery system energization tests are conducted.
  • For liquid cooling systems, pressure tests, pump operation checks, and leak inspections are performed.

4. Environmental Protection Testing (Optional)
Depending on application scenarios, TLS offers specialized testing services:
  • Complete container water tightness testing (mainly for offshore or high-humidity environments)
  • Positive pressure leakage and retention performance testing (for explosion-proof area equipment containers)

5. Final Factory Inspection
Before delivery, the quality control department performs a comprehensive final inspection, including:
  • External appearance and label integrity
  • Dimensions and weight compliance with drawings
  • Full functionality of electrical equipment
  • Completeness of accessory lists, nameplates, packing records, and documentation
Only after passing all checks and signing the relevant conformity certificates can the container be shipped.

6. Quality Documentation
TLS maintains a complete quality record system:
  • Each project has a dedicated quality control file covering materials, fabrication, welding, electrical, commissioning, and testing.
  • Every product has a unique serial number for issue traceability and warranty support.
  • Customer or third-party inspection (e.g., BV, DNV, SGS) is fully supported, including on-site witnessing and acceptance.

Conclusion: Trust Built on Details, Quality Forged by Expertise

From material selection to final delivery, from design drawings to on-site deployment, TLS maintains strict control over every detail—continuously optimizing manufacturing processes and enhancing system reliability. This unwavering dedication to quality has earned TLS the trust of global customers and ensured the successful deployment of our functional containers in critical projects worldwide.

​In today’s global marketplace, the integrity of a product is paramount, especially when that product is temperature-sensitive. This is where TLS's reefer containers come in. More than just a box with a cooling unit, our reefer containers are a crucial link in the cold chain, designed to protect and preserve a wide range of goods—from fresh produce and pharmaceuticals to high-tech components.

Why the Right Reefer Container Is Non-Negotiable
Perishable goods face countless risks during transit. A minor temperature fluctuation can lead to irreversible spoilage, safety hazards, or a complete loss of product value. This is why precision is key. Our refrigerated containers offer a tight temperature control range, typically maintaining conditions between -25°C and +25°C with a minimal deviation of no more than ±0.5°C.

This level of control ensures that your goods arrive in the same condition they left, meeting stringent industry standards like Good Distribution Practice (GDP) for pharmaceuticals and HACCP certification for food shipments.

Engineering Excellence: What Makes Our Reefers Stand Out
The superior performance of our reefer containers is no accident. It's the result of advanced engineering and a commitment to quality.
  • Advanced Insulation: We use high-quality polyurethane (PU) foam with a density of approximately 40 kg/m³. This material is a best-in-class insulator, minimizing thermal exchange and maintaining a stable internal climate. Our standard marine containers feature wall thicknesses ranging from 50 to 120 mm for optimal insulation.
  • Unmatched Durability: Global logistics can be demanding. Our containers are built with high-strength steel and reinforced with precision welding to withstand harsh conditions, including impacts, vibrations, and the immense pressure of being stacked in ports and on ships.
  • Smart Technology: We've integrated IoT and data analytics into our fleet. This means you get real-time monitoring of temperature, humidity, and operational status, giving you complete visibility and control over your shipment at every stage.

The Future is Here: Sustainable and Smart Logistics
At TLS, we're not just keeping up with the industry—we're helping to shape its future. Our next-generation reefer containers are focusing on:
  1. Sustainability: We are actively adopting eco-friendly refrigerants like CO₂ and NH₃ to reduce our environmental footprint.
  2. Energy Efficiency: Innovations such as modular designs and advanced heat recovery systems improve efficiency, which lowers costs and environmental impact.
  3. Automation: Our automated systems for loading, unloading, and monitoring minimize human error and increase operational safety and speed.

Secure Your Supply Chain with TLS
Our reefer containers are more than just equipment; they are a guarantee of quality and reliability. By choosing TLS, you are choosing a partner dedicated to providing a secure, efficient, and sustainable cold chain solution.
