Cleaning and sanitizing
of ventilation
systems in boats


Ventilation systems are not reserved for buildings alone. On cabin-equipped vessels, whether luxury yachts or majestic cruise ships, the air conditioning system is a vital component. These systems extend into every corner below deck through complex air ducts, ensuring a constant flow of clean, conditioned air.

However, just as in buildings, the remediation and sanitization of air ducts on vessels is necessary. Over time, these ducts accumulate dust and grease, creating an ideal environment for the proliferation of molds and microorganisms harmful to human health.

The intervention of cleaning and sanitization is essential to prevent the spread of unhealthy air in the spaces frequented onboard. A regular maintenance plan is generally sufficient to ensure the proper functioning of the system. Periodically, it is essential to replace filters and conduct a thorough cleaning and sanitization of the air ducts, including complete disinfection.

Sanitization of Air Ducts on Merchant Ships:
An Imperative for Safety during the Covid-19 Pandemic

In recent years, the world has been shaken by the global spread of the Covid-19 virus, raising concerns also in the field of merchant ships that are essential for the supply of goods worldwide. The concern about the possible transmission of the coronavirus inside ships is well-founded Even before the pandemic, the law (D.Lgs. 81/2008 – Safety in the workplace) had established the obligation to sanitize the air ducts during extraordinary maintenance.

Ensuring thorough sanitization requires the adoption of strict protocols and the use of cutting-edge technologies capable of reaching every part of the ventilation system.

Entasys stands as the ideal partner for this important sanitization task within vessels. The company holds all the necessary global certifications and boasts top-level proven field experience.

Entasys specializes in the reclamation and sanitization of boats

With two operational headquarters in northern and southern Italy, Entasys is capable of implementing the entire process of remediation and sanitization of air systems for any vessel, tugboat, yacht, or cruise ship stationed in Italian ports.

The procedure implemented by Entasys carries out the entire cleaning, sanitization and sanitization cycle in different operational phases that follow one another:

1 • Study of the air diffusion system in detail: through a visit to the premises of the boat, it is possible to ascertain the regular functioning of the ventilation system below deck;

2 • Visual inspection : Entasys has remote-controlled robots useful for taking an accurate photograph of the points where dirt is thought to lurk;

3 • Cleaning of impurities present along the entire section of the pipes: by means of specific machinery consisting of brushes calibrated with the correct rotation power, the dust is removed, subsequently incrustations or solid material occur which will be removed with aspirators and jets of compressed air;

4 •Sanitation of pipelines: the thoroughly cleaned system can be sanitized to disinfect it from microorganisms.


Cleaning and sanitizing the pipes in a boat is of considerable importance also to limit the spread of fires on board. In fact, even in the presence of fire dampers, the pipes can cause the spread of fire. This happens when the cleaning and subsequent reclamation of the ventilation systems has not been done for too long or has not been carried out correctly. The mechanism is simple: the large amount of dust accumulated in the pipes is easily flammable and constitutes a high risk of fire. The pipes branch into every room and skip the blocking of the fire dampers.

Coating for

In some pipes internally insulated with glass wool, after disinfection, a thin film is applied which makes the pipes perfectly smooth and resistant to bacteria and mold. This process, which is called coating, will make the pipes easily treatable later and sanitized for a long time.
The entire ventilation system is thus treated in depth for the health of the occupants of the boat. The certification issued at the end ensures the validity and conformity of the entire process and of the products used that are part of a category specifically authorized by the Ministry of Health.
