ALL DUCT CLEANING
SERVICES trained technicians that will carefully clean
and sanitise your air-conditioning heating/cooling coil.
Coil cleaning has
become a specialised area of care within air conditioning systems.
The coil is in the air flow path on all air conditioning systems.
Therefore it has direct effect on the rate of air flow, efficiency
of heat transfer and indoor air
quality.
Air conditioning cooling
coils provide moisture, cool temperature and food from dust, all
which are necessary for biofilm growth. The biofilm effects the
cooling coil in the following ways:
Blockages
in the coil. Blockages in the coil decrease
the amount of air passing through the system. This in turn
will effect the air conditioning systems ability to cool the
air. The system tries to compensate for the reduction of cooling
efficiency by running the compressor for longer durations.
Effective maintenance on the cooling coil provides cost savings
in energy consumption.
Corrosion
of the coil. Biofilms will attach themselves
to the fins on the cooling coil. In doing so, they etch into
the surface to provide a secure holding. This etching eats
away at the cooling coil and over time will degrenerate the
cooling coils ability to perform efficient heat transfer.
The solution for coil corrosion is to remove biofilm through
maintenance. The alternative is to replace the cooling coil,
which has a greater cost than coil maintenance.
Reduced
heat transfer. The presents of the biofilm
on the coil surface acts as an insulation media between the
air and the cooling coil. The air flowing through the coil
is not reduced in temperature adequately enough to allow the
system to cool the building efficiently. Due to the inadequate
cooling of the air the building is not reaching the required
temperature, therefore the compressors will run continuously
in order to compensate for the poor temperature transfer.
In a system where the air is cooling the building efficiently
the compressors will cycle in and out of service as required.
Poor heat transfer reflects in poor energy usage. A coil that
is maintained and cleaned offers energy savings.
Poor
indoor Air. Bacteria,
mould and fungi that colonise on the cooling coil create endotoxins,
mycotoxins and a range of toxic allergenic organic fragments
collectively known as macromolecular organic dust(MOD). MOD
compromises the quality of the air within the building, leading
to a range of chronic health complaints. Some adverse health
effects associated with MOD are headaches, eye irritations,
blocked sinuses, nausea, respiratory complaints, allergies,
fatigue and skin irritations. Coil cleaning offers healthier
staff, lower rates of absenteeism, healthier staff offer more
productivity and offers mitigation for OH&S requirements.
As you can see the
benefits of coil cleaning greatly out weight the cost of cleaning.
It is a win win situation with advantages for both staff and building
owner.
The Process
ALL DUCT CLEANING
SERVICES is an
accredited Aeris Guard applicator. All our technicans are trained
by Aeris Technologies in the correct methods of Aeris Guard application.
We use and recommend the Aeris Guard product range. Aeris Guard's
performance and longitivity offer the best solution for our customers
needs.
The air handling
unit(AHU), which houses the cooling coil, is cleaned of debris
using specalised dust extraction equipment.
The internal insulation
of the air handling unit is inspected and repaired as necessary.
The condensate
tray is checked for integrity and the condesate drain checked
for blockages.
The evaporator
coil fins are then checked for damage and repaired as required.
The AHU internal
surfaces are clean using Surface Cleaning Solution. The internal
surfaces are then treated with a Bioactive surface treatment,
which prevents the growth of bacteria, mould and fungi for up
to 12 months.
The evaporator
coil is then cleaned in situ using an enzyme based cleaning product.
This cleaner strips away existing bacteria, fungi, other contaminates
and removes any pre-existing coatings, ensuring a clean surface
for the coil treatment. The cleaning solution is non-corrosive
and completely biodegradable.
Please
note: The use of any corrosive type cleaner on the
coils will eat away at the coil fins and tubing, thus reducing
the life of you evaporator coil.
The coil treatment is applied in
situ to the cooling soils. The treatment leaves a thin coating
on the coil surface. The treatment is formulated to release a
small amount of the active biocides over a period of at least
12 months.
This simple, yet highly effective
maintenance will improve your energy usage, life of plant and indoor
air quality.
