TLS Offshore Containers: Safe Housing for VFD and MCC in Hazardous Zones

Understanding the Challenge

Hazardous zones, often found in industries such as oil/gas rigs, processing refineries, chemical production facilities, flammable liquids storage facilities, fuel transportation, petrol stations, paint production, paper production, etc., are areas where the atmosphere contains, or may contain in sufficient quantities, flammable or explosive gases, dusts or vapours. These zones are classified into three main types based on the likelihood of the hazard being present in a concentration high enough to cause an ignition:

- Zone 1: A hazardous atmosphere is possible but unlikely to be present for long periods of time .
- Zone 2: A hazardous atmosphere is not likely to be present in normal operation or infrequently and for short periods of time 

In such environments, the operation of electrical equipment like VFD (various frequency drive) and MCC (motor control circuit) can potentially ignite these gases, leading to catastrophic incidents. 

The TLS Solution: Positive Pressurised Containers

To mitigate these risks, TLS Offshore Containers International has developed a range of positive pressurised containers. These containers are designed to create a safe and controlled environment for the operation of VFD and MCC. 

The principle behind these containers is simple yet effective. They maintain a slightly higher internal pressure compared to the external environment. This positive pressure ensures that no flammable gases can enter the container, thereby preventing any potential ignition sources from coming into contact with these gases. 

But that's not all. These containers also maintain a suitable working temperature by adopting air conditioning systems. This is crucial because electrical equipment like VFD and MCC can generate heat during operation. Without proper temperature control, this heat can increase the risk of ignition, especially in hazardous zones. By maintaining a suitable working temperature, our positive pressurised containers not only prevent the entry of flammable gases but also manage the heat generated by the equipment, further enhancing safety.

Design and Manufacturing Excellence

Our positive pressurised containers are the result of extensive research and development, coupled with our commitment to safety and quality. They are designed to withstand the harsh conditions of offshore environments, providing reliable and durable housing for your VFD and MCC.

Each container is equipped with a pressure control system that continuously monitors and maintains the internal pressure. In the event of a leak, the system automatically adjusts to maintain the positive pressure, ensuring continuous safety. Additionally, the integrated air conditioning system ensures that the internal temperature remains within the safe operating range for your equipment, regardless of the external environmental conditions.

Benefits of TLS Positive Pressurised Containers

The benefits of using our positive pressurised containers extend beyond safety. They also offer operational advantages. By providing a controlled environment, they help to prolong the lifespan of your VFD and MCC, reducing maintenance needs and downtime. This leads to increased operational efficiency and cost savings in the long run.

Moreover, the air conditioning system helps to keep the equipment cool, reducing the risk of overheating and potential damage. This not only enhances the performance of the equipment but also contributes to energy efficiency.

At TLS Offshore Containers International, we understand the challenges of operating in hazardous zones. That's why we've dedicated ourselves to creating solutions that not only meet these challenges but also enhance operational efficiency. Our positive pressurised containers for VFD and MCC are a testament to this commitment. They are more than just containers; they are a safe haven for your equipment in hazardous zones.
