Dehumidification systems are being re-evaluated in light of environmental concerns.

Swedish company CTT Systems is seeing renewed interest in their Anti-Condensation dehumidification system as the aviation industry shifts its focus to sustainability. When the cabin air is moist, water accumulates in the insulation mats, which over time can make the aircraft between 200 and 400 kilos heavier. The system prevents this buildup of condensation. Adding 200 pounds to the weight of a standard passenger plane necessitates the use of 21 additional tonnes of fuel and an annual increase in carbon dioxide emissions of 66 tonnes.

Our system is a very effective way to reduce emissions and the carbon footprint, and the math is straightforward. Ola Häggfeldt adds that his company’s partners have demonstrated that the electronic equipment requires less maintenance because of the lower humidity in the intermediate space (the area between the cabin lining and the fuselage).

Customers like low-cost carriers.

Dry air is created by running a dehumidifying turbine along the length of the crown area, followed by piccolo ducts that exit the area. More than 3,000 aircraft have been retrofitted or installed with the system since it was first introduced over 20 years ago. Low-cost airlines, which have not been as progressive in their sustainability efforts in the past, are now showing an increased level of interest in finding ways to reduce their emissions.

– Traditionally, the emphasis has been on return on investment (ROI) and the fact that our system is a sound financial decision, which it is. At a time when environmental stewardship is a top priority for airlines, we’re seeing more interest than ever before, especially from low-cost carriers looking to up their game on climate change. Our system is a low-cost option that has a significant long-term impact. Ola Häggfeldt concludes that the high level of interest is not surprising.
