URSA Essential D is an electrochemical activation cleaning and sanitizing system which is the most environmentally friendly way to produce disinfectant liquid onboard ships. It only uses water and table salt to produce a highly effective, non-toxic and non-hazardous liquid that can sanitize surfaces onboard as well as disinfect hands.


The solution has undergone stringent EN microbiological tests and has UK and EU biocide regulations certifications.


The components are activated using a form of electrolysis whereby hypochlorous acid, which is a powerful and safe disinfectant, and sodium hypochlorite solution, an effective cleaning agent are produced. Together, they create a powerful, naturally-occurring disinfectant cleaner and sanitizer that is safe, non-toxic, hypoallergenic, environmentally friendly, with hardly any cost.


  • Simple to install and operate with only salt and water as ingredients

  • Solution lasts for 72-96 hours and can be recycled for reactivation

  • It can be also used in pipes to remove biofilms

  • Standard package comes with dispensers ready to be operated and can produce 30-45 liters per day


The International Maritime Organization (IMO) is discussing through an own working group, the problem of plastic waste in the oceans. URSA has developed a solution that helps reduce plastic waste, improve the working conditions onboard the ships as well as benefit the ship owner through reduced cost.


  • Sadly, at least 8 million tons of plastic end up in our oceans every year. Every day around 8 million pieces of plastic makes their way into our oceans.

  • Reducing bottled drinking water will have a positive effect and be a good step towards reducing and finally eliminating the use of plastics on ships.

  • URSA Essential Water Systems is a new series of sustainable and chemical free drinking water and disinfectant products, that are specifically built to work onboard ships.

  • Our products have proven records for long-term operation on ships and we deliver solutions to some of the largest shipping companies around the globe.

  • Our systems can fit into all types and sizes of vessels, and stand out from competition by offering a marine focused product.
