The Cold Rush cold therapy unit provides consistent cooling and excellent compression. Its durable motor is similar to one you would find in a larger device like an air conditioner or refrigerator. It provides a strong flow rate, yet its brushless motor design is whisper-quiet (30 decibel) making the unit ideal for patients to use while resting. This device is designed to produce low heat transfer from the motor to the water ensuring long cooling times of up to 6 continuous hours. Other features include a locking lid to prevent spills, insulated walls for improved cooling, and lightweight design (4.6 lbs) for easy mobility.
