​In demanding industrial and offshore environments, safeguarding critical electrical equipment is paramount. TLS Offshore Containers provides robust MCC (Motor Control Centre) pressurized cabin solutions, purpose-built to ensure the safety and longevity of your vital electrical infrastructure.

What is a TLS MCC Pressurized Cabin?
A TLS MCC pressurized cabin is a specialized, containerized module designed to house and protect essential electrical components such as Motor Control Centers (MCC), switchgear, Motor Circuit Protection (MCP), Variable Frequency Drives (VFD), and Variable Speed Drives (VSD). These cabins are engineered to shield non-explosion-proof equipment from the damaging effects of harsh climates and potentially hazardous gas atmospheres. The solution encloses the equipment within a weather-resistant container, complete with an entrance door for safe walk-in operation.

In laboratory environments involving flammable gases, volatile solvents, or hazardous samples, explosion protection is not an option—it is a bottom line. Yet, too many organizations treat “positive pressure test chambers” as ordinary boxes merely labeled “explosion-proof,” overlooking the essential safety mechanisms inside. The result? Even a minor leak can trigger a serious accident.

We firmly believe that true explosion protection is not left to chance—it relies on scientific design and systematic engineering.

We break down the explosion-proof capability of our positive pressure test chambers into three critical lines of defense. Each one is a lifeline.

Line of Defense 1: Stable and Reliable Positive Pressure Maintenance System

Positive pressure is the core proactive protection mechanism of the chamber. By continuously supplying air and maintaining a stable positive pressure inside, the chamber effectively prevents external flammable gases from entering—eliminating one of the three essential elements of an explosion: flammable gas.
TLS’s positive pressure maintenance system features:
  • Effective air delivery system: Redundant fans with variable frequency drives ensure stable and adjustable airflow.
  • Intelligent pressure control: Differential pressure sensors combined with PLC control maintain a constant positive pressure threshold.
  • Emergency air cut-off linkage: On pressure loss or electrical fault detection, the system automatically shuts off the gas source and triggers alarms.
It’s not “any airflow will do”—it’s about controllable pressure. This is the foundation that enables the first line of defense to function.

Line of Defense 2: Explosion-Proof Electrical Design and Zoning

Positive pressure cannot eliminate all risks. Electrical systems themselves are potential ignition sources, especially with fans, lighting, heaters, and control units coexisting inside the chamber. Electrical classification and layout must be meticulously planned.
TLS applies:
  • Zone 1 / Zone 2 electrical zoning: High-voltage and control systems are separately arranged to comply with ATEX and IECEx standards.
  • Explosion-proof components: Use of certified explosion-proof lights, sockets, junction boxes, etc.
  • Positive pressure protection for electrical panels (if required): A secondary positive pressure barrier inside the electrical cabinet adds an extra layer of safety.
We don’t just build a “positive pressure shell” — each critical electrical unit has its own independent explosion-proof logic.

Line of Defense 3: Emergency Pressure Relief and Structural Safety Buffer

Even with all systems functioning properly, the chamber must be prepared for extreme conditions such as gas supply fluctuations, electrical short circuits, or abnormal reaction-induced gas buildup. The chamber must be designed to “vent without explosion.”
TLS’s positive pressure chambers incorporate:
  • Overpressure relief valves: Automatically open at preset pressures to protect the chamber structure.
  • Explosion-proof windows and pressure relief panel interfaces: Ready for rapid integration if needed.
  • Hermetic welding and flexible conductive structures: Absorb shock waves to prevent structural rupture and flying debris.
This is not wishful thinking—it is a technical response to risk.

Conclusion: Explosion Protection Is More Than a Label
A truly safe positive pressure test chamber does not rely solely on “explosion-proof certification” to earn trust—it hinges on every detail in the design.

At TLS, we don’t just manufacture a container; we engineer a complete hazardous environment containment system.

​Transporting temperature-sensitive goods offshore presents unique challenges, from harsh marine environments to the critical need for consistent temperature control. For decades, TLS Offshore Containers has been at the forefront of providing robust, reliable solutions. When it comes to safeguarding your perishable cargo, our DNV 2.7-1 certified refrigerated containers are engineered for excellence, ensuring your goods arrive in perfect condition, every time.

The Critical Need for Offshore Reefer Solutions
Imagine fresh produce, vital pharmaceuticals, or sensitive chemicals being transported across vast ocean distances. Without precise temperature management, spoilage, degradation, and significant financial losses are inevitable. This is where TLS refrigerated containers become an indispensable asset. They are specifically designed for demanding offshore conditions, offering a secure and controlled environment for your most vulnerable cargo.

Unpacking the TLS Advantage: Built for Performance
Our commitment to superior quality and advanced technology sets TLS apart as a global leader in containerized solutions.
1. Robust Certification for Offshore Demands: Every TLS offshore container, including our reefers, adheres to the stringent DNV2.7-1 / EN12079 standards. This ensures maximum safety, structural integrity, and reliability in the most challenging marine environments. They also comply with ISO size, CSC, and Customs regulations for seamless intermodal transportation.

2. Precision Temperature Control: At the heart of our reefers are high-performance refrigeration units from industry titans like DAIKIN, CARRIER, or THERMO KING. These units precisely maintain internal temperatures within a crucial range of -20°C to +25°C. An intelligent air duct system circulates conditioned air throughout the cargo, guaranteeing consistent chilled or frozen temperatures.

3. Optimized for All Cargo Types:
  • Perishables (Refrigerated): Ideal for fruits, vegetables, dairy products, meat, and pharmaceuticals. Adjustable ventilation holes within the refrigeration unit prevent spoilage by expelling warm, toxic air produced by living products.
  • Temperature-Stable (Heated): Perfect for goods requiring a consistently stable temperature, such as certain chemicals and electronics.
  • Temperature-Sensitive (Insulated): Suitable for goods vulnerable to temperature fluctuations, including artwork and antiques.

4. Engineered for Durability & Efficiency:
  • Long-Lasting Construction: The outer panel material is crafted from muffler-grade stainless steel, providing high-grade protection, extended container life, and superior insulation properties.
  • Optimized Payload: A light tare weight allows for greater cargo capacity.
  • Streamlined Handling: Integrated forklift pockets ensure easy and efficient loading and unloading.
  • Space-Saving Design: All units are stackable, maximizing deck and yard space – a crucial advantage in premium offshore environments.
