Aircool rooftop package units are equipped with two stage compressor start up control incorporating intelligent time delay relay to protect the compressors from too frequent starts and stops. Units come standard with low and high pressure cut out switches as well as compressor current protection.

The durable, weather resistant construction includes 5 step anti-corrosion treatments, 1000 hours of rigorous salt spray testing, heavy gauge galvanised plates, alloy fan blades and stainless steel bolts.

A fresh air damper allows for up to 25% fresh air to be introduced into the indoor space. Washable nylon filters complete the package.  

A check button and LED allows the technician to check the operation status of the unit.  Units are fitted with external gauge ports to make it easy to check the unit’s refrigerant charge. The unit’s belt driven forward curve centrifugal fan can be adjusted using the fan/motor guide rail. This ensures accurate air speeds and pressures resulting in lower noise levels.
