Honeywell Attune is the ideal cooling solution for a multitude of applications such as UAM, military, and civilian aircraft including fixed wing platforms.  The system uses advanced technology such as a high-speed centrifugal compressor, next generation refrigerant and power electronics with Silicon Carbide switches, to generate cold air or liquid that can be used to cool heat-generating electronic components, batteries, and aircraft cockpits and cabins.

Honeywell already is working with several UAM market innovators to apply Honeywell Attune technology in their air mobility platforms.Honeywell already is working with several UAM market innovators to apply the Micro VCS technology in their air mobility platforms.

Our innovative Honeywell Attune (formerly known as Micro VCS) is up to 35 percent lighter and 20 percent more efficient than conventional systems with comparable cooling capacity. The system is highly reliable and virtually maintenance free, thanks to its unique oil-free technology and small number of moving parts, resulting in low total cost of ownership. The Honeywell vapor cycle system (VCS) design experience is based on mature, fielded units that have performed reliably in demanding environments such as the A350, B737, B777, F35, and multiple other defense and business aviation platforms.

Honeywell has extensive experience in VCS technology for aerospace applications and is an innovative and well-proven provider of high-speed centrifugal compressors, the critical component of the system. For more information please contact us.

Keep Cool in Hot Weather

Los Angeles

Los Angeles is known for year-round great weather, but when temperatures increase during the summer months, the heat can be unpleasant, and at times dangerous. The tarmac at Los Angeles International Airport averages 140°F in the summer heat.

Tampa

Tampa summer days at the Tampa airport are long, hot, and wet, with asphalt temperatures often reaching above 100°F. Tampa is also one of the most humid cities in America, with average annual humidity levels at 74%.

Dubai

Dubai has hot, tropical desert climate. On a typical summer day, temperatures constantly sit around 122°F, and sometimes swell to over 140°F, according to recent reports.
