Ossur Cold Rush® features a durable motor, a stronger flow rate than the competition and longer cooling times thanks to an industry-leading ice-to-water ratio. Better yet, it is whisper-quiet and compact, (4.6 lbs or 2.1 kg). Cold Rush uses a much larger motor resembling the units in mobile air conditioners and refrigerators. This provides consistent cooling and excellent compression, even to high elevations. A brushless motor produces whisper-quiet (30 decibel) operation, allowing patients to get better sleep during their rehab.
A very high ice-to-water ratio and design that produces less heat transfer from the motor to the water combine to ensure cold therapy pain relief for up to 6 continuous hours. That's because Cold Rush is more than just a modified beverage cooler. Cold Rush was designed holistically, with unique features like a locking lid to help prevent spills and insulated walls for improved cooling.
