New regulations are calling on cruise ship operators to reduce fuel consumption and lower their environmental impact.


According to health expert VIKAND, air purification systems can help meet both objectives, promising high return on investment, reduced fuel costs and significantly lower CO2 emissions.


VIKAND’s Air Purification solution, supported by its patented Pyure Dynamic Protection technology, has been proven to lower cruise ship emissions and energy consumption, the company claimed.


Through higher air recirculation and less air exchanges, this system reduces a ship’s heating, ventilation and air conditioning (HVAC) load, which typically accounts for a significant portion of a vessel’s energy consumption.


VIKAND said that the system can reduce energy consumption by up to 3% for cruise ships. Aside from the direct savings on fuel consumed by the ship, reduced HVAC plant cycling will extend maintenance intervals, decrease the vessel’s carbon footprint and decrease cylinder head temperatures/pressures, which reduces the formation of combustion by products (such as NOx/SOx) and increases the vessel’s overall efficiency.


Air purification is one of the least expensive and most efficient ways to save significant energy on a ship, whilst promoting measurable environmental goals, the company added. Air purifiers also ensure that air and surfaces remain free from pathogens and contaminants through continuous cleaning.


VIKAND’s system pro-actively eliminates viruses, bacteria, volatile organic compounds (VOCs), allergens and more.



The benefits of air purification

  • Saves energy and reduces carbon emissions through higher recirculation and cleaner HVAC systems.
  • Helps to meet sustainability and ESG goals, whilst enhancing guests and crew welfare on
  • Minimises indoor air pollution and promotes good health on
  • Eliminates up to 99.9999% of viruses, bacteria, mould, odour, and fumes in less than 20 mins in the air, and under 60 mins on surfaces.
  • Generates a fast return on investment and huge savings potential on energy/fuel costs, whilst reducing CO2


Air purification continuously relieves the HVAC system of having to draw in hot and humid outside air. It also reduces air resistance, so air handlers don’t have to work as hard to push air through the HVAC system. This lowers energy consumption, costs and carbon emissions.


Aside from the direct savings on fuel, air purification can also extend the HVAC system’s maintenance intervals, VIKAND said.
