The IC cooler includes an integrated Pneumatic pump inside the cooler lid and a 120V wall adapter. The Aircast Cryo cuff IC compression system features an integrated pump design to provide you with both cold and focus compression to reduce edema and pain after surgery. The new design works by building up pressure inside the cooler to drive cold water out of the hose to the anatomically contoured pad. The Cryo cuff IC is compatible with most existing pads and provides cold and compression therapy to any part of the body. The system utilizes a 30 second intermittent on/off cycle instead of a continuous circulation design for longer life.
