CTT | Humidity In Balance


Who benefits

The planet – Lower fuel consumption. Less emission

The less fuel burned the cleaner the atmosphere. Imagine saving up to 65 tons of CO2 per aircraft and year (!), as is the case with a narrow-body aircraft. Or up to 160 tons with a wide-body aircraft in regular service. The calculations also show significant reductions of nitrogen oxides, hydrocarbons and carbon oxide.

The airline – Better overall economy

Calculations based on experience from actual installations and reports from operators of our systems, show that the payback period for a Zonal Drying™ System in an aircraft can be as short as 1 to 2 years, depending on the type of operation and aircraft.

The payback period is shortest for operators with high aircraft utilization and high passenger load factors. Not to mention the values of operational reliability, passenger comfort and the effects on the environment.

The airplane –Less electrical failures

Many of the electrical wires in the aircraft are located in the space between the inner lining and outer skin, right where condensation accumulates. This triggers warning signals and short circuits in sensitive equipment, resulting in delays and component replacements – if not worse.

Longer life cycle

Corrosion mainly affects the areas around aircraft windows, doors, antennas and belly structures. Floor beams and electrical connectors are also exposed. This means extra expense for the airlines since they often have to replace structural parts at D-checks. If moisture is removed, the risk of accumulating corrosion on the airframe is minimized.

The passengers –No rain in the plane

During take-off and landing, passengers and crew are often exposed to what is commonly called ”rain in the plane”. Especially during descent or take-off, when water seeps along fissures in ceiling panels and people on board are exposed to dripping water. This is caused by water floating on surfaces on top of the overhead panels. It is condensed water that has not been drained out of the aircraft. This is not news. The news is that you can actually prevent this from happening. This is how.

The crew – Effective insulation

Condensed water permeates the insulation making it heavier and significantly reducing its insulation effect. When people on board feel cold draughts at windows and doors, this is one of the explanations. Also, since wet insulation is the perfect environment for mould, fungus and mildew, passengers as well as crew and maintenance staff may develop allergic reactions.

During maintenance, parts of the insulation may have to be dried or replaced. This entails extra costs for the airlines, while still only providing a temporary solution to the problem – once the aircraft re-enters service the insulation will soon be soaked again.
