Portamarine® Benefits

The Portamarine has been specifically designed to meet the needs of the shipping industry and has proven a capable and reliable unit over many years. In use with many thousand Vessel and Marine service stations worldwide, it is specifically designed for safely, quickly and accurately inspecting marine CO2 fire suppression systems. It allows vessel owners to comply with IMO SOLAS requirements which specify the need to have the means onboard to allow crew to safely inspect the fire systems. The Portamarine® has been specifically designed for testing multi-banked CO2 Cylinder Fire Suppression System Cylinders, stored in 2, 3 or 4 rows deep, to make the process as quick as possible to complete. It can also operate on the vast majority of other fire system agents including FM200, NOVEC 1230, Halon (for Defence applications) and all other clean agent systems.

Coltraco Limited has produced this liquid level indicatorspecifically to meet the corresponding needs of Marine Industry.The equipment is fully Classification Society Approved, accurate to +/-1.5mm and proves a significantly safer and quicker solution when compared to weighing as a means of identifying cylinder content.

Integrity and Science Key to Our Culture of Performance

Dear Coltraco Customers, Strategic Partners and Distributors,

Integrity is our defining value. Performance is its consequence. We understand that our customers have choices, and how we perform determines whether customers choose us. Coltraco’s Code of Ethics does not merely require compliance with laws. It embodies a Commitment to positive behaviours that build trust, promote respect, operate with distinction, with courtesy and global levels of performance, demonstrating our integrity and delivering customer performance.

We honour our commitments, communicate transparently, and act with honour. Ethics are the foundation of our performance culture and our science-based approach. We lead in specific technologies delivering the watertight integrity monitoring of marine structures and the monitoring of fixed liquefied gaseous fire extinguishing systems and the room integrity of protected space to ensure agent hold-times post-installation. We show this by our understanding of the science in them and the mathematics that explain them.

I would like to thank you for your business and for the relationships with our Customers, Strategic Partners, Distributors and ODAs who we value so highly.
