About CTT SYSTEMS (Publ.)
Cair™ is focused on the passengers’ health and comfort by providing
humidification of the extremely dry aircraft cabins without causing
condensation. Cair™ gives a pleasant relative humidity of around 20%, compared
to 3-5% without, for the passengers, thereby reducing dry air related problems
(e.g. fatigue, jet-lag, red eyes, dry skin, spread of virus diseases).
The Cair™ system is based on evaporative cooling technology and uses a method
that effectively precludes the transfer of bacteria within the aircraft. The
dual-purpose system increases humidity for greater comfort and incorporates the
Zonal Drying™ System to counter condensation problems.
CTT’s Zonal Drying™ System has been selected as basic equipment for the new B787
“Dreamliner” and CTT’s humidifiers are options in crew rest compartments and on
the flight deck. The A380 offers CTT’s humidifiers as option in crew rest
compartments. CTT will also supply the Zonal Drying™ system and the Cair™ system
for the A350 aircraft, as options.
CTT is the de-facto standard for non-condensation systems preventing condensate
water to accumulate (read: excess weight) in commercial aircraft structures and
the dominating provider of humidification products for cockpit, crew rest and
cabin areas. CTTs products Zonal Drying™, Cair™, Flight Deck and Crew
Humidifiers are standard or optional equipment on the Boeing 787, Airbus A350
and the A380.

Some dry facts on long-haul traveling
· The only humidity contribution in an aircraft is from passengers and crew
· The cabin with less seat density and with the highest cost per seat is
ironically the one with the lowest humidity!
· The Relative Humidity (RH) is lower than 5% in First Class and 7-10% in
· Crew Rest Compartments typically encompass a RH well below 5 %
· The extremely dry air in the cabin cause human discomfort, such as cold and
allergy symptoms, sleeping difficulties, dry skin and eyes and general fatigue.
· Medical studies prove that even a slight RH-increase from extremely low
levels, is beneficial to health, as the increased humidity improve tear film
stability and nasal patency. It also reduces headaches and ocular, nasal and
dermal dryness symptoms.
CAIR™ - Cabin Humidification a landmark in premium traveling
· Airlines no longer are limited by the extreme-dry-air-law-of-nature setting
the statutory condition for their in-sky offering
· Passenger will benefit more from all cabin interior investments such as
seating – feeling more at ease and pleased
· Passengers and Crew gain from improvements in wellbeing, rest and over-all
· Flavors will be more accessible in the palate and healthier too, with no
need to over doze anything such as salt or sugar
· Increased Humidity is an ‘enabling ingredient’ for more varieties, new
species, flavors and combinations in the sky
Zonal Drying™ - by eliminating fuselage condensation both operational and
maintenance costs will be lowered through:
· lowered fuel consumption (i.e. lower aircraft weight - 200-300 kg on
A320/B737 due to elimination of accumulated water),
· improved operational reliability (i.e. less corrective maintenance),
· consistent insulation performance (i.e. water reduces insulation
· reduced fuel burn also has a positive impact on the environment and finally
· Condensation issues are increasingly important to airlines as fuel stands
for some 40 % of OPEX.
