About us
ROTO designs and manufactures high-quality polyethylene components for the marine industry — including fuel tanks, freshwater and greywater tanks, and a wide range of custom-engineered parts for various types of vessels.
Our in-house development, tooling, and production capabilities ensure full control from concept to serial manufacturing. With advanced rotomoulding technology and electric robots, we achieve exceptional material homogeneity, structural strength, and consistent quality across every product.
Each component is engineered for seamless installation and delivered as a plug-and-play solution, optimising integration time and reducing assembly costs.
Combining marine-grade durability, precision engineering, and sustainability, all our products are 100% recyclable and meet the demanding requirements of OEM and shipyard partners worldwide.
With over 50 years of experience, ROTO stands as a leading European manufacturer in rotational molding technology, consistently delivering quality and sustainability in every application.
Products

Custom welded tank
Advantages of custom made welded tanks: suitable for fresh water, grey water, waste water or fuel tank ideal for small custom made series of tanks (batch size 1 - 10) ideal for large sizes of the tanks ideal for making prototypes - fast realisation of project no investment in special tooling - low startup costs lower tank weight in comparison to metal assembling and testing - plug & play - assembled tanks, ready for build in the boat tank connections directly integrated into the tank tanks have integrated buffles to protect sloshing and improve stifness Our tanks are made from high strength, advanced materials: high-density polyethylen (HDPE) polypropylene copolymer (PPC) Our tanks are produced by experienced and licenced staff and comply with the following ISO standards: EN ISO 21487:2018 “Small craft - Permanently installed petrol and diesel fuel tanks” EN ISO 8099-1:2018 “Toilet waste retention systems”

Black water tank
Our advanced rotomoulding processes enable the production of large-volume tanks up to 20.000 liters in a single piece, accommodating complex and customized geometries to fit any available space on the vessel. Lightweight compared to traditional metal tanks, yet engineered for durability and resistance to harsh marine environments, our tanks deliver reliable performance under the most demanding conditions.
