Gelair is a product that uses tea tree oil to treat HVAC systems and improve indoor air quality. It works by dispersing tea tree oil vapors throughout the HVAC system and connected rooms via a gel matrix. Tea tree oil is a natural essential oil that kills mold, bacteria, viruses, and inhibits influenza viruses. Studies show Gelair is effective at controlling airborne bacteria and has been used successfully in hospitals, offices, and offshore rigs to reduce sick leave and increase productivity by treating the entire HVAC system. It provides a simple, energy-efficient way to improve indoor air quality compared to other options.

4. Increased instances of sick building syndrome
By adding a Gelair block to your AHU,you have a natural,effective way of
making sure your ducts remain healthy and more importantly,the air entering
the occupant zones is treated for mold,bacteria and viruses.

What is Gelair?
A patented system, using a specially formulated gel
matrix placed in a fan dispenser, where it releases
specific concentrations of top quality tea tree oil vapor.
Tea tree oil (a 100% natural essential oil) is a broad
spectrum anti-­microbial and anti-­fungal agent.

Journal Abstract
In vitro antiviral activity of Melaleuca alternifolia
essential oil
Lett Appl Microbiol. 2009 Dec;49(6):806-8. Epub 2009 Sep 18.
Garozzo A., Timpanaro R., Bisignano B., Furneri P.M., Bisignano G., Castro A.
Aims
To investigate the in vitro antiviral activity of Melaleuca alternifolia essential oil (TTO) and its main
components, terpinen-4-ol, !-terpinene, "-terpinene, p-cymene, terpinolene and !-terpineol.
Methods & Results
The antiviral activity of tested compounds was evaluated against polio type 1, ECHO 9, Coxsackie
B1, adeno type 2, herpes simplex (HSV) type 1 and 2 viruses by 50% plaque reduction assay.
The anti-influenza virus assay was based on the inhibition of the virus-induced cytopathogenicity.
Results obtained from our screening demonstrated that the TTO and some of its components (the
terpinen-4-ol, the terpinolene, the !-terpineol) have an inhibitory effect on influenza A/PR/8 virus
subtype H1N1 replication at doses below the cytotoxic dose. The ID50 value of the TTO was found
to be 0#0006% (v/v) and was much lower than its CD50 (0#025% v/v). All the compounds were
ineffective against polio 1, adeno 2, ECHO 9, Coxsackie B1, HSV-1 and HSV-2. None of the tested
compounds showed virucidal activity. Only a slight virucidal effect was observed for TTO (0#125%
v/v) against HSV-1 and HSV-2.
Conclusions
These data show that TTO has an antiviral activity against influenza A/PR/8 virus subtype H1N1
and that antiviral activity has been principally attributed to terpinen-4-ol, the main active
component.
Significance & Impact of the Study
TTO should be a promising drug in the treatment of influenza virus infection.

To Whom It May Concern,
At EMAS we are continuously looking to improve the working conditions for everyone in
our company. As the superintendent aboard the Lewek Champion, one of my main
concerns is ensuring we provide the highest standard of indoor air quality to all of our staff.
As with all offshore environments, there is often a dense population of people in a confined
space, providing perfect conditions for bacteria and viruses to spread amongst the crew.
This leads to a vast reduction in productivity and increased time off work due to illness.
To limit the spread of diseases and to increase productivity, we looked into various indoor
air quality products and after reviewing the options available, we decided to use the Gelair
product range as it offered the best holistic solution.
The simplicity of the product means your crews do not require any training and there is no
maintenance whatsoever. It effectively treats the entire HVAC system (unlike most
alternatives) and is a registered green product as it does not consume any energy.
After installing the Gelair blocks in our air-conditioning system we have seen a noticeable
improvement in productivity and a vast reduction in sick leave. By using the Gelair system
we can ensure that we are providing clean, healthy air to everyone on board.
After using Gelair, we can confidently recommend the product to others who are focused
on reducing sick leave and increasing productivity on their rigs and vessels.

34. Maximize Heat Transfer / Reduce
Energy Consumption
Heat conductivity of aluminum is approx 200W/m.K
Whilst that of biofilm is approx 0.2W/m.K

35. Maximize Heat Transfer / Reduce
Energy Consumption
Conductivity has fundamental implication on heat
transfer, clean coils devoid of biofilm obviously offer
significant efficiency advantages.

37. Biofilm extrudes acidic substances which
corrodes aluminum cooling fins
