Anti-corrosion protection method for every size

Cocoon Holland BV delivers tailor-made solutions to your storage challenges. Our expertise covers a wide range of objects prone to corrosion—from aircraft idle during the pandemic to ships, and from heat exchangers to full-scale industrial plants.

Protect your investments effortlessly with our cozting to prevent rust on steel. Our innovative systems maintain the air surrounding your valuables well below the corrosion threshold. For smaller items or short-term storage, simply use our effective drying agents. They absorb moisture quickly and keep rust at bay.

For larger assets or longer-term needs, consider our advanced economiser system. It’s a smart choice: fully automated air dryers circulate dry, unheated air continuously, keeping the environment ideal for preservation. These systems rejuvenate their drying agents automatically, ensuring consistent protection without hassle.

Ensure your critical equipment stays in pristine condition, no matter the storage duration. With Cocoon Holland BV, safeguarding your valuable assets becomes simple and reliable. Let’s keep your equipment ready and operational, whenever you need it.

Anti-corrosion Drying Systems for every size

Cocoon Holland BV specialises in ready-made solutions for storage problems. We provide made-to measure work for all objects subject to corrosion, whether this is an aeroplane, a ship or expensive apparatus such as heat exchangers, conversion installations or even entire factory installations.

Depending on the format and the duration of conservation of the object, the condition of the enclosed air is kept beneath the so-called ‘rust-border’ in a simple way. This can be done for small objects for a short period of time by using an absorbent drying substance. For larger objects, and for longer periods of storage, we will install an ‘economiser system’, which is controllable. For this we use automatically regulated air dryers, which keep the enclosed air constantly in circulation. The air-dryer produces unheated, dry air and automatically regenerates the built-in drying substance.

Coatings for aircrafts and ships

The outer shell of an aircraft is crucial. You can fully mothball an aircraft, securing everything from engines to electronics and all systems in between!

Ships, however, demand a different approach. You need to ensure every interior space — the engine room, living quarters, deck houses, even the funnels and air shafts — is completely airtight. Deck equipment also gets its own protective enclosure. Our Cocoon Mothballing System lets you access the ship’s interior anytime without affecting the preservation quality.

Back in 1960 in Den Helder, the first mine sweepers were preserved using our Cocoon System. Fast forward to 1976, these ships were back in action with just a standard equipment check — the same as you’d perform after just three months of inactivity.

During those 16 years in storage, the mothballed sections, including nautical and weapons systems on deck, needed no maintenance. This preservation method proved so effective that minesweepers have been regularly mothballed ever since.
