Element construction and operation is illustrated in the figure. Pressurizing the unit compresses the brake springs and withdraws the water jackets from the brake discs. Heat generated at the friction interfaces is quickly transferred to the circulating coolant.

Element sizes are indicated by the number of friction discs and the disc diameter in inches. For instance, size 224WCS has two friction discs 24 inches in diameter.

Features	Unique friction couple. A specially formulated friction material, interfacing with a copper alloy surface, eliminates the stick-slip characteristic associated with ordinary frictional devices. Rapid heat dissipation. The copper interface conducts heat rapidly to the circulating coolant. Open or closed loop coolant systems. The element works equally well with open or closed loop circulating systems. On mobile equipment, the engine’s cooling system can be tapped to provide coolant to the element. Optional corrosion protection For marine environment applications, protective coatings are available to minimize corrosion.
