TEMPERATURE CONTROL

    Internal temperature control remains an issue in transport category, VIP and special operations aircraft. Temperature control for the cockpit and the aircraft electronics has been of particular interest to our customers. For example, two crucial systems, inertial navigation (INS) and global positioning (GPS), are sensitive to high temperatures and will not activate in extreme temperature environments. Traditionally, typical on-board Air Cycle Machine (ACM) technology can take up to two hours to reduce the temperature far enough to allow the INS and GPS systems to activate. This is expensive and a harsh operating environment for ACM and APU operations just to cool an aircraft cockpit on the ground. Some military operators are performing preflight checks, after takeoff, at altitude where they have access to the cooler air.
NASI technology has demonstrated that temperatures can be reduced to acceptable levels in as little as 10 to 20 minutes, and at costs substantially lower than those associated with ACM technology operated by an APU with a full pneumatic load. One of the reasons most cited for the poor performance of traditional air cycle technology is "heat sink", which occurs as cold air passes through ducts which run along the heat-soaked fuselage. NASI systems can provide direct cooling with little or no ducting required up to 120,000 BTU/Hour.

NASI Engineers have delivered hundreds of air conditioning, heating and cooling solutions for transport category aircraft. Designed with significant technological improvements, the NTEC Systems deliver superior reliability and performance for a cool return on investment. Some operators can see this return in a single season.

NASI also offers custom arrangements of NTEC Aircraft Air Conditioning Systems. Electric works where noise and air pollution regulations prohibit use of APU operated ship systems.

Many areas prohibit use of APU operated ship systems before departure. NTEC Supplemental Electric Systems are the cool solution.
