As consumer demand for fresh food quality and safety continues to rise, the cold chain logistics industry is entering a period of rapid development. At the heart of this evolution lies the reefer container—the essential carrier for temperature-sensitive goods. As a specialist in reefer container solutions, TLS is committed to delivering efficient, safe, and intelligent cold chain transportation systems.

Why Is Refrigerated Transport So Essential?
Fresh produce and perishable goods spoil rapidly at ambient temperatures due to microbial growth and enzymatic activity. A controlled low-temperature environment significantly slows down these processes. At temperatures below -18°C, over 90% of the water content in food turns into ice, suppressing microbial activity and extending shelf life.

How Do Reefer Containers Work?
Reefer containers are equipped with independent mechanical refrigeration systems, capable of maintaining a wide temperature range—from +25°C to -25°C. TLS reefer containers, for example, are compatible with various international power standards and support pre-cooling, intermodal transport, and precision temperature control strategies. These features ensure that cargo remains within optimal temperature thresholds throughout the journey.

The State of Reefer Transport in China
Although China is now a global leader in reefer container manufacturing, the cold chain logistics infrastructure is still developing. Currently, only 10% to 30% of transported goods use refrigerated logistics—far behind the 80% to 90% in developed markets like Europe and the U.S. According to industry data, inadequate cold chain coverage results in over ¥70 billion (~$10 billion USD) in food loss annually in China.
However, this is changing. Driven by evolving consumer expectations and growing awareness of food safety, China's cold chain market has been expanding at a compound annual growth rate of 10%–15%. As a critical tool for long-distance, cross-regional delivery, demand for reefer containers is rapidly increasing.

How Are Reefer Containers Evolving?

1. Upgraded Materials for Greater Durability
New-generation containers use high-strength weathering steel like COR-TEN, offering enhanced corrosion resistance and structural stability across sea and land transport conditions.

2. Improved Thermal Insulation
Advanced insulation materials such as polyurethane (PU) foam are replacing older options. With thermal conductivity up to three times lower than traditional layers, combined with high-reflective coatings and optimized construction methods, energy efficiency is significantly improved.

3. Eco-Friendly Refrigerants
Legacy refrigerants like R12 and R22 are being phased out due to their ozone-depleting effects. Transitional refrigerants such as R134a and R404A are currently used, while research into natural, eco-friendly refrigerants continues to accelerate.

4. Energy-Saving Technologies
Variable-frequency compressors and fan systems allow the refrigeration unit to automatically adjust based on real-time demand, reducing energy consumption and improving operational efficiency.

5. Smart Refrigeration Systems
Digital controls are replacing manual operations. Modern scroll compressors offer better energy efficiency, compact design, lower noise, and even controlled atmosphere (CA) capabilities for gas environment regulation within the container.

6. Remote Monitoring & Smart Management
With the rise of IoT, wireless communications, and sensor technologies, reefer containers are becoming increasingly intelligent. TLS is exploring solutions involving temperature sensors, wireless modules, and remote monitoring systems to enable real-time tracking of internal conditions, system performance, and container safety.
This push toward greater visibility and automation improves response times in case of anomalies, boosts transport efficiency, and enhances safety across the cold chain network.

Looking Ahead
As cold chain logistics continue to thrive, reefer containers are entering a new era--smarter, greener, and more efficient than ever before. Whether in food, pharmaceuticals, or seafood exports, reefer containers are playing an increasingly vital role.
At TLS, we remain committed to innovation and sustainability. Our goal is to deliver next-generation reefer solutions that are not only reliable and efficient but also aligned with the future of intelligent logistics.

​Introduction: Prioritizing Safety in Hazardous Environments
Industrial safety, especially within demanding offshore settings, hinges on correctly identifying and managing hazardous areas. These zones pose significant risks due to potentially explosive atmospheres. Understanding their classification – Zone 0, Zone 1, and Zone 2 – is the first step towards implementing effective safety protocols. This post will clarify these zone definitions and explain why specialized equipment, like pressure containers from TLS Offshore Containers, is essential for safe operations within these environments.
 
What Are Hazardous Areas? Zone 0, Zone 1 & Zone 2 Explained
Hazardous areas are defined locations where the air contains flammable gases, vapors, or dust in quantities sufficient to create explosive or ignitable mixtures. Proper classification is vital not just for safety, but also for regulatory compliance. The key difference lies in the frequency and duration of the explosive atmosphere's presence:
 
1. Zone 0: Maximum Risk Environment

• Definition: A Zone 0 area is characterized by the continuous or long-term presence of an explosive atmosphere (flammable gas, vapor, or mist mixed with air).
• Common Locations: Think inside storage tanks, pipelines, or confined vessels where hazardous substances are consistently present. These areas demand the highest level of safety precautions.

 
2. Zone 1: High Probability Risk Environment

• Definition: In Zone 1 areas, an explosive atmosphere is likely to occur occasionally during normal operations.
• Common Locations: This zone often surrounds Zone 0 areas. Examples include locations near pump seals, valves, flanges, or connections where leaks might occasionally happen under standard operating conditions.

 
3. Zone 2: Lower, Short-Term Risk Environment

• Definition: A Zone 2 area is one where an explosive atmosphere is not likely to occur during normal operation. If such an atmosphere does form, it will only persist for a short period.
• Consideration: While lower risk than Zone 0 or 1, Zone 2 areas still require careful management and appropriate safety measures.

In oil and gas drilling operations, modular functional containers play a vital role in ensuring both safety and operational efficiency. Among the most commonly deployed modules are the Drilling Fluid Lab Cabin and the Mud Logging Unit (MLU). While these two systems often appear together on drilling sites, they serve fundamentally different purposes in terms of function, configuration, zoning requirements, and explosion-proof standards.

Distinct Functional Roles
The Drilling Fluid Lab Cabin is primarily used to test and adjust drilling fluid (mud) properties to ensure optimal performance across different drilling intervals. It is operated by mud engineers and is designed to monitor key parameters such as density, viscosity, pH, sand content, and fluid loss. Based on these results, the mud formulation can be promptly optimized to meet well-specific demands.
The Mud Logging Unit, on the other hand, functions as a real-time geological monitoring center. Through integrated sensor systems, it continuously collects and analyzes critical data such as cuttings, gas content, mud flow, and pump pressure. This data is used by geological engineers to evaluate subsurface formations, detect abnormalities, and support decision-making during the drilling process.

Different System Configurations
The Drilling Fluid Lab Cabin is outfitted with laboratory-grade equipment including test benches, density meters, filter press units, viscometers, and mixing tools. It also requires reliable ventilation, drainage, and lighting systems to support laboratory operations in field conditions.
The Mud Logging Unit integrates advanced sampling and monitoring instruments such as gas detectors, cuttings analyzers, data acquisition terminals, and industrial-grade computers. Data is typically visualized in real time and transmitted to the central control system, forming part of the broader drilling information network.

Zoning and Explosion-Proof Standards
These two modules are deployed in different safety zones based on site-specific hazardous area classifications. The Drilling Fluid Lab Cabin is generally positioned at the periphery of the platform or in designated safe areas—either Safe Area or Zone 2 depending on the site layout. While not always mandatory, Zone 2 explosion-proof designs are often recommended to ensure safety compliance.
In contrast, the Mud Logging Unit is typically located closer to the wellhead or return mud flow line, often within Zone 1 or Zone 2 hazardous areas. As such, it must be built to meet strict international explosion-proof certifications such as ATEX, IECEx, or UL, including explosion-proof electrical components, lighting systems, and positive pressure ventilation to ensure safe operation in hazardous environments.

Differences in Operational Mode
The Drilling Fluid Lab Cabin is operated on a shift-based schedule. Tests are conducted periodically based on operational needs, with the lab ready to respond around the clock if required.
The Mud Logging Unit, however, operates 24/7 without interruption. Staffed by engineers on rotating shifts, it ensures continuous monitoring of downhole data throughout the entire drilling process.

As digital transformation accelerates in the oil and gas industry, Measurement While Drilling (MWD) and Logging While Drilling (LWD) technologies are evolving from traditional data collection tools into intelligent systems that support real-time drilling decisions.
However, in order for these systems to function reliably in extreme environments, a robust and intelligent physical platform is essential. That’s where high-performance LWD/MWD containers play a critical role—not only protecting equipment but also serving as the core hub for data processing, communication, and environmental control.

1. Designed for Harsh Field Conditions
Some LWD/MWD units are installed near the wellhead, where they are exposed to high temperatures, humidity, vibration, dust, and explosive gases. These challenging conditions place stringent demands on the container design:
