Chilled water actuators control the amount of chilled water going to the chilled water coil. Chilled water systems provide air conditioning typically to large buildings. These air conditioning systems, or cooling systems, use cold water which is piped through a coil in a large air handler. Read more below.

Chilled water actuators control the amount of chilled water going to the chilled water coil. Chilled water systems provide air conditioning typically to large buildings. These air conditioning systems, or cooling systems, use cold water which is piped through a coil in a large air handler. The chilled water actuator can modulate allowing only a certain amount of cold water to reach the chilled water coil. Depending on the cooling supply air set point will depend on where the chilled water actuator will modulate the chilled water valve in the chilled water system piping.
Chilled water systems offer an economical way of cooling large commercial buildings. These air conditioning systems are a great alternative to direct expansion constant volume air conditioning systems. There are constant volume air conditioning systems which use chilled water but most constant volume air conditioning systems use direct expansion. Many chilled water systems are used for VAV systems where there are many zones on a large air handling unit. Both constant volume air conditioning system and VAV zoning air conditioning systems can be either direct expansion or chilled water systems. Chilled water actuators, in chilled water systems, offer control of the flow of chilled water which is routed to the chilled water coil.
