Donjoy IC cooler (Semi-Closed vs. Restricted Flow)
A semi closed loop system allows the warm water to re-circulate in donjoy IC cooler. This happens at a constant flow rate. The cooler provides a constant distribution of water throughout the pad. With a 2 hose system you can be rest assured you will get a constant flow of cold water which will create enough compression and help your joints to recover faster.
