There are two basic types of solenoid valves. The most common is the normally-closed type, in which the valve opens when the coil is energized, and closes when the coil is de-energized. The other type is the normally-open valve which opens when the coil is de-energized and closes when the coil is energized. For secondary coolant applications it is important to use system capacity, type of fluid, temperature and pressures. It is not recommended to size by line size.

Secondary coolant systems are advantageous because they eliminate liquid refrigerant. This reduces installation
costs and labor, and eliminates costly refrigerant leaks. Also, PVC tubing can be used, rather than the heavier, more expensive copper tubing normally used in traditional systems. Another benefit is more efficient defrost cycles with less potential product damage.
