Emerson Flow Control (Alco) 097998 36" Pressure Switch 145-623 PSI PSC-B6S

The Emerson Flow Control (Alco) 097998 36” Pressure switch is suitable for complex HVAC systems. This switch works as a safety relief switch that can operate at pressures ranging from 145 PSI to 623 PSI. It measures system pressure and if the pressure goes higher than the set limit it turns on a switch to stop the equipment. This helps in avoiding the effects of overpressure conditions and safeguarding parts such as compressors, pumps, heat exchangers in chillers, boilers as well as large air conditioning systems. Advantages are reduction of repair and time losses, the proper functioning of systems, and increasing safety.
