TLS Pressurized Modules: Certified Safety for Zone 1 & Zone 2 Operations

In high-risk industries such as energy, chemical processing, marine engineering, and intelligent manufacturing, achieving the perfect balance between safety and functionality is paramount. TLS Offshore Containers has drawn on years of expertise in explosion protection, fire resistance, airtight design, and modular integration to develop a new generation of advanced pressurized containers — engineered for safe, reliable, and customized deployment both offshore and onshore.

What Is a Pressurized Container?A pressurized container, especially in its explosion-proof (Ex p) form, is an engineered enclosure capable of maintaining positive internal pressure. By keeping internal air pressure higher than the external environment, it effectively prevents the ingress of flammable gases — making it ideal for deployment in hazardous Zone 1 and Zone 2 areas. These containers provide isolated environments for critical operations in some of the world’s harshest conditions.

Five Key Advantages of TLS Pressurized Containers1. Certified for Global Safety Standards
TLS containers are certified to major international standards, including DNV 2.7-1, EN 60079-13, IECEx, and ATEX. They are fully compliant for use in offshore drilling rigs, FPSOs, LNG terminals, and onshore hazardous zones — ensuring maximum safety wherever deployed.

2. Fully Customizable Design
From container dimensions to electrical systems and interior layout, TLS offers full customization to meet project-specific needs. We provide modular integration of MCC rooms, control stations, VFD cabins, or data acquisition and transmission hubs — all prefabricated to reduce onsite installation time.

3. Reliable Positive Pressure System
Our engineered ventilation system maintains a stable positive pressure environment through air supply, pressure monitoring, and fail-safe interlocks. Automatic alarms or power shutoff mechanisms activate if pressure drops or doors are opened, ensuring system safety and ease of maintenance — even in long-term remote operations.

4. Built for Harsh Environments
TLS containers feature marine-grade anti-corrosion coatings, A60 fire-rated insulation, and reinforced structural designs for wind, vibration, and extreme temperatures. They are built to perform in offshore conditions, desert oilfields, or high-altitude remote sites.

Typical Applications

• Offshore Oil & Gas Platforms: As MCC cabins, instrumentation rooms, or UPS enclosures
• LNG Terminals & Refineries: Electrical control rooms in Zone 1/2 hazardous areas
• Energy Storage Systems: Isolation chambers for lithium battery safety and gas control
• Ports & Shipyards: Fire- and explosion-protected enclosures for smart control systems
• Extreme Environments: Mobile control centers and communication hubs for high-altitude, cold, or humid climates
