Rather than running at one or even two speeds, the 20LX Inverter-Driven Scroll Compressor changes its speed in small, precise increments and adjust cooling up and down like a dimmer switch. So temperatures are held exactly where you want them, even in extremely hot weather.
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. The coil features rifled tubing to enhance refrigerant flow, while lanced coil fins increase surface contact between metal and air. They combine for maximum heat transfer and efficiency.
