We use specialist flushing equipment and safe, non-toxic and biodegradable marine growth removers specifically formulated to meet an industry wide need for fast, safe, cost effective alternatives to mechanical cleaning of seawater cooled equipment.

Engine’s overheating, dreading that huge bill from the mechanic to pull apart your engine and mechanically clean it? Toilet pipes blocked, loo does not flush, bad odours in your vessel? We have the solution to cut your costs dramatically and keep your vessel working like a wristwatch.

What we’ll do during your flushing and descaling

Our team at Stella have specialist flushing equipment to flush pipes, heat exchangers, Air Conditioning, Refrigeration plant and toilet pipes. We can tackle full pipes work systems on Superyacht’s right down to the smallest heat exchanger or refrigeration plant on the weekend cruiser.

Why you need to flush

Calcium build-up

All Seawater systems do by nature form a calcium scale build up and also can grow barnacles and other marine growth in the pipes reducing flow of water through the system. The Calcium build up inside heat exchangers works like insulation and can reduce the heat transfer between substances such a seawater and coolant or refrigerant. For this reason, it is necessary to ensure you keep your heat exchangers and pipes clean and clear.


Toilet pipes and Uric Scale

Toilet pipes also gather a build-up of a very hard Uric Scale over years of use, Vacuum toilets are especially prone to this build up due to low water use during flush. As this Uric scale forms, it can cause complete blockage of the pipes and cause foul odours which can leach through PVC hose.

The best alternative to mechanical cleaning:

Barnacle Buster

Stella is the importer of the Trac Ecological Range of Products including Barnacle Buster, Descaler and Sew Clean, to name a few. Barnacle Buster ® is a safe, non-toxic and biodegradable marine growth remover specifically formulated to meet an industry wide need for fast, safe, cost effective alternatives to mechanical cleaning of seawater cooled equipment. With minimal dismantling required, Barnacle Buster ® can be safely re-circulated through seawater cooling systems, dissolving barnacles, zebra mussels, calcium, rust, lime & all other mineral deposits.


Sew Clean

Sew Clean is formulated to target uric scale and clean sewage systems from toilet to tank, this proven solution can dissolve clogs causing plumbing to overflow and create nasty odours. Sew Clean® builds upon the proven Barnacle Buster® formula and takes it one step further. Special attention has been given to ensure that foam and bacteria are significantly reduced while flushing. Like all of TRAC ’s products, Sew Clean® is non-toxic, biodegradable and safe to use on all types of material commonly found in Black water systems.



Trac’s Descaler is designed specifically for fresh and brackish water applications, TRAC Descaler® can safely be used within engines, cooling towers, boilers, or just about any other system re-circulating water. TRAC Descaler® will not harm gaskets, seals, plastics or any metals commonly found in water systems.

Unlike other competitors, Trac does not use any harsh acids, instead they use a mild, food-grade phosphoric acid blend. TRAC has developed a truly innovative formula by actually changing the acid’s properties, thus turning them into the safest and most effective descalers on the market!

    It was a simple financial decision for us choosing the Stella unit instead of installing new tank and roof area for catchment. We no longer rely on rainfall opportunities, just turn on the switch.
