Cruise Ship HVAC systems

Ultraviolet “C” is the ultimate anti‐viral solution for  Cruise Ship HVAC systems

A Cruise ship has special HVAC challenges and as such requires special HVAC systems. A frequent, fast and furious turnaround of passengers (many ships with over 5,000 passenger capacity), disparate needs room to room, area to area, and often high humidity and moisture levels; these are the perfect breeding ground for a pandemic.

Time and time again, cruise ships experience serious outbreaks of illnesses such as Norovirus amongst passengers and crew. (e.g. 150 passengers on “Diamond Princess”, February 2016; 132 passengers on “Anthem of the Seas; Feb/Mar 2016; 173 passengers on “Carnival Sunshine” Feb/Mar 2016; 300 passengers on “Golden Princess”, March 2016; 252 passengers on “Balmoral”, April 2016; 131 passengers on “Disney Wonder” April/May 2016). 

Correctly specified* and installed on the ship HVAC systems, UVC will destroy airborne Norovirus and other pathogens, strengthening a ship’s resilience to the spread of infection and help vessels pass the US CDC Vessel Sanitation Program inspections. (*recommended 90,000 to 100,000 µws/cm2 UV intensity)

Norovirus is a highly contagious and debilitating illness. The virus easily becomes airborne, circulating in the ship, ruining vacations. As few as 10 viral particles can cause infection; as a reference point, the average stool or vomit volume can contain over 100 million particles (Source: Washington State Department of Health).


Without regular preventative maintenance and cleaning, ship ventilation systems can quickly become contaminated resulting in poor indoor air quality, infections and and foul odours – and complaints from passengers and crew alike. However, scheduling HVAC maintenance can be difficult due to system accessibility, chemical use and downtime.

Correctly specified and installed on the air-off side of cooling coils, UVC will

  • prevent the build-up of bio-film on the heat-exchange fins
  • eliminate or greatly reduce the need for coil cleaning (and all that means in avoiding disruption)

Without UVC, cooling coils can quickly become coated in bio-film – a source of pathogenic micro-organisms – bacteria, viruses and mould.

By removing bio-film with UVC, the heat-exchange performance of coils is kept at design specification 24/7/365, saving energy. (Ref. SEEMP – Ship Energy Efficiency Management Plan)

Combining the highest performing Steril-Aire™ UVC (ultraviolet-C) technology with experienced and skilled professionals, we can help implement clean, safe and energy efficient ship HVAC upgrades.

Our UVC for HVAC solution can help:

  • Decrease operating costs: Reduce energy/fuel consumption per guest through HVAC system heat transfer improvements and increased net cooling capacity. Reduce maintenance costs for HVAC unit.
  • Improve HVAC system performance and reinstate it to its original specification. Reduce the risk of HVAC equipment failure when at sea.
  • Improve guest retention and renewal by improving and maximizing HVAC performance in extreme tropical conditions.
