Alco Controls
Emerson is the leading provider of precision electronic and electromechanical controls for air conditioning and refrigeration systems. Founded in 1925 as Alco Valve Company, Emerson Climate Technologies Flow Controls continues to pioneer the control of refrigerant flow with innovative designs like expansion valves, moisture indicators and filter driers.
- Our Hermetic Moisture Indicator (HMI) is the most sensitive moisture indicator in the HVAC/R industry.
- Our line of expansion valves have a stainless steel power element that eliminates power failures caused by corrosion.
- Our solenoid valves have the lowest leakage in the industry.
- Our filter driers have a combination of filtration and moisture and acid removal that provides the best protection of any filter drier available.
