Switch for Chilled Water/Glycol

Chilled Water/Glycol Pressure Switches. These switches operate like all other pressure switches. They make electrical contact when a certain set pressure has been reached at their input. The characteristic that differentiates them from other switches is the requirement to operate in chilled water air conditioning systems that must cool below the freezing temperature of water. The switch components that transport the water/glycol media are usually made of copper.
