Integrated Compressor Protection: The combination of both high and low pressure switches give additional reliability to each Armstrong Air cooling unit. The high pressure switch prevents operation in the event that refrigerant pressures exceed safe levels, protecting the compressor. In the event that your unit does not have enough refrigerant, the low pressure switch prevents the unit from drawing in moisture and other contaminants while operating.
Armstrong Air’s proprietary heat transfer system. A specially designed fan shroud pulls air evenly throughout the air conditioner’s coil surface. The coil features rifled tubing to enhance refrigerant flow, while lanced coil fins increase surface contact between metal and air. All combine for maximum heat transfer and efficiency.
