Description
The Emerson Flow Control (Alco) 099030 High-Pressure Control Switch M/R is a safety part that is used to protect HVAC systems from high pressure. This high-pressure switch ranges between 87 and 464 PSI and has a 3-feet long capillary tube which makes it flexible to install. It constantly checks pressure within the system and sounds a bell or turns off the system if pressure hits a certain threshold. This reduces the chances of damaging the equipment, reduces the time the system takes to be up and running again, and improves the reliability of the system.
