Cruise Ships


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

Cruise ships have special HVAC challenges – 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.

PASSENGER HEALTH AND WELLBEING: 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 in the ship’s 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).

UVC for enhanced HVAC PERFORMANCE: 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.
