The Edge Tub Elite uses a 1HP commercial grade compressor to chill water 4x faster than most other cold tubs. Actual cool down time will depend on the starting water temperature and ambient air temperature. In our testing, we have found that The Elite Chiller will cool the water at a rate of about 10-12°F per hour or heat at a rate of 12-15°F per hour. If your starting water temperature is 65°F, this means that the water will cool to sub-40°F or above 100°F in about 2.5 hours. If desired, the cool down process can be sped up by adding ice while filling the tub with water.
The Edge Tub Legacy uses a .8HP compressor to chill the water at a rate of 5-8°F/hr
*testing for the above rates were done at ambient temp of 65°F
