Air Hygiene Services for Superyachts, Cruise Ships, Offshore and More

Clearvac provides extensive marine vessel air hygiene services, including HVAC ventilation system cleaning. These services are essential for meeting industry standards, insurance mandates, and health and safety regulations. We ensure the air circulated in occupied areas consistently meets the required standards.

In the case of extraction systems, we also address the removal of Fire Hazards and provide certification for insurance purposes.

Air Hygiene Risk Assessments

We perform an initial vessel walk through, followed by a comprehensive photographic and video assessment of all HVAC ducting and components. We examine air handling units, blower fans, ducting, return and supply plenums, vents, grilles and so on.

This forms the basis of our service report.

 

 

Mold Assessment and Removal

Mold remediation is a crucial component of vessel health maintenance. All vessels despite age, size or build are the perfect environment for mould growth, this is determined by the constant exposure to varying humidity and moisture, which collects in the often convoluted, complex and entangled ventilation systems. Black spores are incredibly toxic and release mycotoxins into the vessel environment, posing a great risk to crew health and damaging interiors. 

Our services eliminate all growth and prevent future spore colonies forming.

 

Air Handler Coil Cleaning

The air handler coil unit (Air Handling Unit – AHU) – Is the most essential component in a vessel’s ventilation system. A dirty Coil promotes the dispersion of mould and bacteria  throughout the entire system. Our procedures enable us to thoroughly clean and sanitise  the interior and external casing of air handlers, including system condenser coil, blower fan motor’s internal chambers, evaporators, drain pans, and housing tracks.

HVAC Ventilation Systems Cleaning and Disinfection

Vessel air duct cleaning is also an essential component of a well-considered maintenance schedule. Poorly maintained air ducts on large vessels with high occupancy accelerate the growth of mould and bacteria.

As part of the air duct cleaning service, we thoroughly clean and sanitise the supply and return ducts end-to-end. This detailed process also includes components that distribute airflow, like supply and return air plenums, air vents, grilles, diffusers, extraction fans, transition boxes, louvred vents, and so on.

Air Purification and Ozone Treatments

(Mould, Bacteria, Virus and Odour Elimination)

Clearvac Engineering Asia employs ozone technology as a natural method to disinfect and sterilise internal living and working spaces. This technology is the most effective agent for neutralising bacteria, viruses, microorganisms, mould, fungi, larvae, and odours, making ozone a more potent and environmentally friendly solution compared to hazardous chemicals. Bacteria tend to thrive in environments with limited ventilation, warm temperatures, and humidity.

Clearvac offers ozone treatments using our custom industrial, European-built ozone generators. These machines sanitise internal spaces, eliminating contamination without any residue remaining, and as always, we cause minimal disruption to crew and guests.

The Science In Detail

Virus

Bacteria are small, single-cell organisms with uncomplicated structures encased in relatively robust cell membranes. Ozone disrupts the metabolism of bacterial cells, impeding and obstructing their enzymatic control system.

A sufficient amount of ozone penetrates the cell membrane, leading to bacterial destruction. In contrast, viruses are small, independent particles composed of crystals and macromolecules. They can only multiply within a host cell by transforming the host cell’s proteins into their own. Ozone eliminates viruses by entering their protein coat and targeting the RNA at their core.
