For the yacht market we distinguish two exhaust systems: dry and wet, sometimes combined in one system. The choice for a wet or dry exhaust system is not an easy choice. A wet system has its known advantages, but need, even more than a dry exhaust system, the best of engineering on subjects as water volumes, temperature control, choice of materials and welding. We supply that best of engineering. TIO supplied its first water injectors yet in the early nineties for ultra high standard navy applications and since then we have developed a broad know-how and superb range of products.
