Tyco Fire & Integrated Solutions supply Marine manually operated waterspray systems for the protection of ships carrying liquid fuels and liquefied gases in bulk. We also supply Pre-Wet Spray systems for Nuclear Biological, Chemical Defence (NBCD) onboard Naval Armed Forces ships.

Our waterspray systems for the protection of bulk carriers are designed in accordance with the requirements of the I.M.O.
