Nozzle solutions and systems for civil shipping

Civil navigation includes commercial shipping and tourist shipping, which are used on inland waterways and seas mainly for the commercial transport of goods and passengers. Container ships, cruise ships and yachts are the most common types of ships.

Whether it's for commercial shipping, voyages on a cruise ship or military applications – spray solutions from Lechler offer optimum solutions for your applications. Thanks to our expert knowledge and many years of experience, Lechler is much more than just a supplier of nozzles. Working together with you, we are able to optimally design many of your applications and processes for maximum efficiency – e.g. for cleaning, safety and cooling on board.

Application overviews for commercial shipping

Application overviews for commercial shipping Dirt and salt encrustations can be softened and removed using flat fan, tongue-type or full cone nozzles. Large spray angles and lower flow rates are preferred for this. Lechler can meet these requirements with their nozzle range. We recommend nozzles from the series 632, 652, 686, 684, 490 and 422. Installation is made easier by a wide range of accessories. Exhaust gases are desulfurized using full cone nozzles and the media salt and fresh water. Nozzles from the series 403, 405 and 421 are ideally used. The emission values from the funnel are reduced with highly efficient droplet separators. Droplet separators for vertical gas flow are mainly used here. Rotating tank cleaning nozzles can be used in these applications. Driven by the medium, these nozzles clean the tank walls in a precisely defined path by means of flat jets or gear-controlled solid streams. Spray balls can also be used for small tanks. Lechler air intake systems are used for efficient protection against sea water, rain or fog. Separator systems for reducing fluid content in combustion air. Nozzles are used here for cooling and fire protection of the freight or containers with closed hatch covers. We recommend full cone nozzles with protection cap of the series 400/401. Lechler flat fan nozzles installed in the lashing bridges can help to stop fires spreading and minimize damage to the ship and cargo. Exhaust gases are desulfurized using full cone nozzles and the media salt and fresh water. Nozzles from the series 403, 405 and 421 are ideally used.

Lechler air intake systems are used for efficient protection against sea water, rain or fog. Separator systems for reducing fluid content in combustion air. For cooling tanks and installations, it is extremely important to evenly spray the entire object with water from all sides or to ensure a uniform water film on the surface. The smallest nozzle cross section should be >= 6 mm (DIN 14495). We recommend tangential full cone nozzles from the series 422.
Application overviews for commercial shipping In this application, the exterior shell on lifeboats is protected against heat and fire. The water film is sprayed backwards so that the shell of the lifeboat is completely wetted and cooled with water. We recommend the series 500.393, 686 and 490/491. Efficient extinguishing by means of rotating pop-up foam extinguishing nozzles. Spray diameters of up to 9 m and spray heights of up to 5 m. In accordance with CAP 437. These nozzles were developed especially for seagoing tugs or supply ships, for example, and are used for fire protection on the ship walls during burning oil slicks. The water film runs down and wets the entire wall and protects it against strong heat. Efficient extinguishing by means of rotating pop-up foam extinguishing nozzles. Spray diameters of up to 9 m and spray heights of up to 5 m. In accordance with CAP 437. Lechler air intake systems are used for efficient protection against sea water, rain or fog.

With constant growing global trade, maritime trade will also continue to increase. 98 percent of intercontinental trade and 62 percent of internal European trade takes place by means of commercial shipping. A wide range of applications for nozzles in commercial shipping make them an indispensable part of this giant economic sector.

Nozzles are used for fire protection in particular, but also for various cleaning tasks such as exhaust gas scrubbing or tank cleaning.

Application overview for cruise ships and yachts

Application overviews for civil shipping Exhaust gases are desulfurized using full cone nozzles and the media salt and fresh water. Nozzles from the series 403, 405 and 421 are ideally used. Droplets can be carried along in the gas stream during the absorption process. These droplets are optimally removed from the gas stream with vertical-flow droplet separators from Lechler. Full cone nozzles of the series 490 are available for cleaning the droplet separators. Deposits in exhaust gas pipes can be removed by means of Lechler flat fan nozzles and rotating cleaners of the series 573/583. Dirt and salt encrustations can be softened and removed by means of flat fan, tongue-type or full cone nozzles. Large spray angles and lower flow rates are preferred for this, requirements that can be met by our nozzle range. We recommend nozzles from the series 632, 652, 686, 684, 490 and 422.
