In industrial and offshore environments, the stable operation of motor control equipment is essential. TLS MCC shelters are engineered to provide a safe and reliable space for customer-installed electrical systems, featuring modular design, robust structure, and positive pressure protection.

Modular Design for Flexible Configurations
Built with a modular enclosure structure, the TLS MCC shelter can be easily configured, expanded, or combined according to site requirements. Whether in an onshore plant, wind farm, or offshore platform, the enclosure offers flexible layouts to accommodate Motor Control Centers (MCCs), switchgear, and VFD/VSD panels.
Multiple standard sizes (16ft, 20ft, 40ft) are available, and customized dimensions can be provided for special project needs.

Positive Pressure System for Equipment Protection
The MCC shelter uses a pressurized ventilation design that keeps internal air pressure slightly higher than the external environment. This prevents dust, moisture, and corrosive air from entering the enclosure, ensuring a clean and stable environment for sensitive electrical components. The result is longer equipment lifespan and reduced maintenance.

Built Tough for Harsh Environments
Constructed from high-strength, corrosion-resistant steel, TLS MCC shelters are designed to operate in extreme temperatures, salt-laden air, and harsh climates. The structure complies with IEC 60079-13, DNV 2.7-1, and EN 12079 standards, allowing deployment in ZONE 1, ZONE 2, or safe areas.

Each enclosure is equipped with basic electrical wiring, lighting, sockets, and emergency escape features, ensuring both safety and practicality.

Easy Transport and Rapid Deployment
TLS MCC shelters are ISO-compliant with corner castings and lifting points for land and sea transport. Installation on site is straightforward — the plug-and-play design and detailed installation guide help reduce commissioning time and increase project efficiency.

Wide Applications and Adaptability
Designed to house low and medium voltage switchgear, control panels, PLC systems, and auxiliary devices, TLS MCC shelters are ideal for renewable energy, petrochemical, mining, and offshore industries.

Their modular and customizable nature allows flexible expansion or layout adjustment as project needs evolve.

Conclusion
By combining modular construction, positive pressure protection, and durable design, the TLS MCC shelter provides a secure and adaptable space for electrical control systems.
Whether for onshore facilities or offshore operations, it is the ideal solution for safeguarding critical equipment and ensuring continuous performance.

​As a global manufacturer of BESS containers, TLS Energy specializes in the design, fabrication, and testing of containerized Battery Energy Storage Systems (BESS) tailored to customer requirements.

Among all quality assurance procedures, the water spray test is one of the most critical steps, ensuring that each BESS container achieves IP55 waterproof protection for long-term and reliable outdoor operation.

Why Water Spray Testing Is Essential
BESS containers are typically installed outdoors, exposed to rain, humidity, wind, and temperature changes. The water spray test verifies that every container enclosure provides full protection against water ingress, keeping the internal electrical and control components safe.

Without proper water resistance, moisture could lead to corrosion, insulation breakdown, or short circuits, which may affect performance and safety. Therefore, TLS Energy conducts water spray testing on every unit before delivery to ensure consistent sealing quality and reliability.

TLS Energy’s In-House Water Spray Test Procedure
TLS Energy has developed its own in-house testing procedure specifically for large-scale BESS containers. This process simulates real rainfall and strong water jet conditions to confirm the integrity of the container’s waterproof design.
The testing process includes:
  1. Pre-Inspection – All door gaskets, hinges, air filters, and sealing strips are checked to ensure proper installation and condition.
  2. Spray Simulation – High-pressure nozzles spray water over the roof, side panels, doors, and cable entry points from multiple directions and for a set duration, reproducing real outdoor rainfall conditions.
  3. Post-Test Inspection – After spraying, the container is opened and carefully inspected. No water droplets or damp areas are acceptable inside any compartment.
  4. Documentation – A Water Spray Test Report is issued for each tested unit, including test pressure, duration, and results, signed by TLS Energy’s quality assurance engineers.

Components Protected Inside the BESS Container
TLS Energy’s BESS containers integrate all key energy storage and control systems within a single IP55-rated enclosure, including:
  • Battery packs and racks – energy storage modules providing core capacity
  • BMS (Battery Management System) – monitors and balances battery operation
  • FFS (Fire-Fighting System) – enables rapid fire detection and suppression
  • DC Control Cabinet – manages electrical distribution and safety circuits
  • TMS (Thermal Management System) – maintains stable temperature inside the container

The water spray test ensures all these systems remain fully protected and operational even under heavy rain and severe weather.

Engineered for Long-Term Durability
TLS Energy’s container structure adopts a multi-layer waterproof design, featuring EPDM rubber seals, stainless-steel hardware, IP-rated glands, and anti-corrosion coatings.
Together with precise manufacturing and strict testing, this design guarantees reliable IP55 protection and outstanding performance in all environmental conditions.
​
Commitment to Quality and Safety
At TLS Energy, quality and safety always come first. Every BESS container undergoes a full factory acceptance test (FAT), including electrical insulation checks, thermal system verification, fire-safety validation, and water spray testing.

This commitment ensures that every TLS Energy product delivered to clients meets the highest standards of reliability, durability, and performance in real-world energy storage applications.

​Are you pushing drilling operations into extreme territories? Your data acquisition and personnel safety rely on robust MUD logging cabins built to withstand anything from the Arctic to offshore rigs. TLS Offshore Containers delivers specialized, certified, explosion-proof solutions that ensure operational integrity and maximize safety, wherever your rig is located.

Why Choose a TLS MUD Logging Cabin for Extreme Environments?
MUD logging is the nerve center of drilling—providing vital real-time data, gas analysis, and downhole monitoring. Standard containers simply can’t meet the demands of modern, high-stakes exploration. TLS cabins are engineered specifically for this challenge.
