AC430 Roof-Mounted Air-Conditioning System Maximizes Solutions for the Mid-Size Bus Market

Oct 6, 2008

San Diego, Calif., United States

Carrier’s new AC430 roof-mounted air-conditioning unit offers mid-size and school bus fleets and passengers high-performance cooling in a lightweight, sleek package. The AC430 system is on display at the International Public Transportation Expo 2008 in San Diego, Oct. 6-8.  Carrier Corp. is a subsidiary of United Technologies Corp. (NYSE:UTX).

The AC430 system uses Carrier’s micro-channel heat exchanger (MCHX) coil technology, which delivers significant performance improvements through better heat transfer and thermal performance. MCHX technology has been widely used in millions of automobiles since the early 1980s. 

Able to better withstand dirt and road treatment agents and easier to clean thanks to its enhanced robustness, the MCHX coil increases system reliability and life by offering better corrosion resistance. In fact, Carrier’s MCHX coils exceed ASTM B 117 corrosion test minimum requirements by 50 percent. The MCHX condenser’s single-row coil design also helps reduce the amount of refrigerant needed to circulate through the system.

The AC430 produces 14 kW (48,000 Btu) of air-conditioning capacity at ARI (Air Conditioning Refrigeration Institute) cooling conditions, with a total electrical consumption of only 42A/80A at 24V/12V, respectively.

Weighing only 176 pounds the aerodynamic, one-piece AC430 system is easy to install and strikes an optimum balance between performance, reliability and efficiency.

“With the addition of the AC430 system, Carrier offers a complete line of solutions for the mid-size and school bus market,” said Joseph Giacona, product manager, Carrier North America Bus.
