American Cooling Technology (ACT) recently released its new high-performing, low profile CR-2 roof-mount condenser unit, designed to minimize the weight placed on the roof of a bus as well as reduce overall height.

The CR-2 further expands ACT's existing North American product line that includes a full range of split system air-conditioning units for small to mid-size school and shuttle buses.

At 7 inches tall, the low height of the CR-2 unit increases roof clearance and provides a cleaner, sleeker look to the air-conditioning installation. The low profile and tapered leading edge of the unit eliminates the need to install a branch guard typically required on a standard rooftop condenser. At 43 pounds, the lightweight design makes the CR-2 unit a good fit for both conventional and hybrid-drive buses.

Officials said that by relocating the air conditioning condenser from the typical position under the bus floor to the roof of the bus, the capacity and operating efficiency of the air-conditioning system improves because the system uses cleaner air from the top of the bus through the unit's heat exchanger.

The design specifications of the CR-2 unit include a one-piece "drop in" construction to simplify and reduce the time it takes to complete the installation. In addition, the unit's modular construction allows for improved access to internal components, making it easier to service.
