• Lowers Air-Conditioning energy costs 15% to 25%• Installation takes less than 30 minutes • ROI’s can be less than 12 months• 100% Maintenance-Free

Air-Conditioning typically represents the largest portion of a facility's electricity consumption, coming in at 40% to 60% of the overall electric bill. This mounts up to tremendous amounts of capital for many Companies

American Solar Energy Group has the Solution!

What is an AircoSaver?It is a retrofit product that adds intelligence to air-conditioning systems, which saves KWh and extends compressor life.

• Sensor driven software algorithms designed to detect thermodynamic saturation and optimize compressor run times.

• Provides anti-short cycling; mandatory compressor off time after thermostat reaches set point (3 min) or loss of power (1 min).• Reduces equipment operating temperature and prevents evaporator freeze-over by properly cycling the compressor.

• Constantly adapting its settings to inside demand requirements & outside weather conditions.• AircoSaver has been engineered & manufactured in Germany for over seven years!

• Package Units (RTU)• Split Systems• PTAC• Window Units• Wall Units

The AircoSaver will work in all types of AC systems, typically up to 20 tons.
