Emerson Flow Control (Alco) 065398 1/2" FXM Flare Moisture Indicator HMI-1FM4

The Emerson Flow Control (Alco) 065398 1/2” FxM Flare Moisture Indicator HMI-1FM4 is a used in the HVAC systems to check for the presence of moisture in the refrigerant line. This indicator has a flare connection and a maintenance. It works through a desiccant material which shifts color when it comes into contact with moisture. This change of color provides technicians with a visual that moisture is present and can be damaging to refrigeration equipment. In this way, the HMI-1FM4 allows eliminating the moisture problem and avoiding expensive repairs while increasing the durability of HVAC systems. This is mainly helpful for use in refrigeration systems that deal with hygroscopic refrigerants like those that contain ammonia or water.
