On board many Yachts, Cruise ships and Ferries ducted H.V.A.C. and/or Exhaust ventilation systems have been installed. International studies on indoor and outdoor pollution show that the indoors is more polluted than the air outside. In fact, research proves explicitly that the air in some Yachts is 10 to 100 times more polluted than the air outside!
Research
Research has also shown that no less than 30% of Yachts, Ferries and Cruise ships have to cope with indoor air quality problems
Sick Buildings
These problems manifest themselves for the users of these vessels in so-called "Building Related Illnesses" (BRI) with symptoms such as headaches, listlessness, excessive weariness, irritations of the mucous membranes and running eyes. These symptoms, and the as yet undetected causes, are often also linked to "sick Building Syndrome (SBS).
Again research has proved that the cause of 50% of BRI can be found in the heating, ventilation and airconditoning (HVAC) system. The pollution present in the HVAC system is one of the most important sources of BRI.
A dangerous myth
Tradition says that an HVAC system automatically and without maintenance provides a comfortable and safe indoor climate. The recent awareness of BRI and SBS proves that this is a myth.
A close look at polluted ducts
If air ducts in Yachts, Ferries and Cruise ships are not maintained properly, they are a serious source of health risk. After all, the HVAC system is an ideal breeding ground for dust, micro-organisms and bacteria, mould, pollen. These pathogenic contaminants enter the indoor climate through the ventilation system and can have disastrous effects on people's health.

Effective Duct Cleaning - important for people's health, productivity and product quality.
Vessels with a polluted indoor climate are a threat to the health of the users and are the cause of high sickness rates. There are no precise figures as to the degree of (economic) damage caused worldwide by BRI.
Duct Cleaning and productivity
Polluted HVAC systems not only cause severe health problems in vessels but those same problems arise at home, in hospitals, industry, offices and public transport and everywhere people stay for longer periods.
The symptoms of BRI are often hidden, but a polluted indoor climate is expensive' it costs money indirectly (low productivity) and directly (absenteeism due to illness).
The consequences are clear; reduced concentration at work results in lower productivity and-in the end lower quality of products made, the services offered and pollution as well as illness.
Air Duct Cleaning - Standard maintenance procedure
Costs reduction policy
Everyone who feels responsible for an optimum inner climate, continuity and productivity should pay structural attention to the right degree of maintenance of the HVAC system. With current knowledge of the impact of BRI and SBS, duct cleaning should be an integral part of all modern maintenance procedures. After all people's health is at stake.

The HPV air duct cleaning concept - the unbeatable system
The High Pressure Vacuum (HPV) System is the standard of excellence in air duct cleaning technology.
|
How it works
The HPV System ensures thorough cleaning of air ducts using compressed air. The pressure is regulated according to the size and type of duct, and naturally to the pollution in the duct
The HPV System reaches every part and location in heating, ventilation and air conditioning (HVAC) systems, in other words the system guarantees integral, high quality cleaning everywhere in the air duct system.

The HPV Method
Endoscopy
Random endoscopic pictures are used to estimate the degree of pollution in the entire HVAC system. If the client wishes, air samples can be taken by an (independant) Air Quality consultant to determine the Indoor Air Quality (IAQ) before the cleaning project starts. This approach gives clear insight into the extent of the task and the best way of tackling it
|
Vacuum
When the contract has been awarded, the HVAC system which needs to be cleaned is divided into number of duct sections. Each duct section in turn is selaed off from the rest of the system. A Hepa extraction unit creates a negative pressure in that section.
|
High Pressure Cleaning
Through a small opening in the duct wall, the HPV cleaning unit is introduced into the duct. Sections are then cleaned in one single action. With a firm, pulsating current of compressed air the HPV unit removes the dirt from the duct wall and the suction created by the Hepa equipment removes the suspended material from the system.
|
Advanced technology
During the cleaning process the HPV cleaning unit moves through the heart of the duct. The-so-called Spider keeps the nozzle centered, guaranteeing that the HPV system always cleans more effectively than an un-centered cleaning system. Moreover, the HPV system Spider protects the ducts from damage o the inside caused by an un-centered nozzle. Furthermore, the Spider concept minimizes noise during the cleaning process. The HPV system was uniquely designed so that the compressed air keeps the nozzle centered and transports the system as well as, of course, cleaning the ducts.

The HPV System - Basis for a winning IAQ Business
HPV System
The Multifunctional
Air Duct Cleaning Concept
|
Benefits
- The HPV System guarantees perfectly cleaned air ducts and easily meets the highest quality standards (cleanliness) in the air duct cleaning branch
- Obstacles in the ventilation ducts do not influence the cleaning result
- Two small opening in the main duct wall are sufficient (minimal damage to the ventilation system
- The nozzle centering ensures excellent cleaning results, prevents damage and minimizes noise pollution
- The HPV System is multifunctional : air ducts can be cleaned, disinfected and coated using the system
|
Multifunctional
- The HPV System can be used for treating all types of air ducts : in public buildings, schools, houses, hospitals, yachts, ships, trains and offs-shore utilities, In short, wherever this is an HVAC system
- The HPV System cleans both horizontal and vertical air ducts equally effectively
- The HPV System treats round, square and oblong air ducts with equal ease
- The HPV System cleans ducts both small (from Ø 5 cm) and large (Ø 1 m)
- The HPV System also treats construction ducts and ducts insulated on the inside
|
Productivity and return
- With the HPV System air duct sections with a length of 135 meters can be cleaned in one single cleaning action
- The HPC System works effectively with uninterrupted sections of unlimited length
- High productivity (meters per operator-hour) is maintained despite curves, fire valves and other obstacles in duct systems
- Easy of operation ensures low labor costs
- Low cost price per meter guarantees a high return on the investment in the HPV System
- By taking simple precautions air duct cleaning can even take place during office hours (process continuity for the client)
