Cold Plunge Pool - Chiller Tubs
The Chiller Tub is a specially designed cold plunge tub that enables users to benefit from cold water therapy. This type of therapy is used in Nordic Spas and for sports injury and muscle recovery. Our “chiller tubs” utilize a commercial aquarium water refrigeration unit, to do the cooling, in addition to an external circulation pump and filter, results in the refrigerated water being circulated through the tub. The refrigeration unit also has its own digital temperature controller, thus not requiring a separate external controller.
Our Aqua Therapy tubs are ideal for use as a cold water therapy tub but this system can be used on any of our hot tubs or Ofuro’s. The extra 5 ft tub depth allows full body immersion while still being a safe depth for most adults.
How it Works
The equipment is powered through a pool/hot tub timer. This allows adjusting the time(s) when the pump will run in order to achieve filtering. During these “on” periods, and only then, the water can be cooled by the refrigeration unit, if the temperature is above the setting.
Such water refrigeration systems as shown above, is of commercial quality and the hydraulic circuit is very much similar to a soaker gas heated system, except it cools instead of heating. The diagram also depicts the use of an optional spa pack that would make the tub dual purpose, either a hot tub or a chiller tub. Also note just like a heater can’t cool, the refrigeration system can’t heat. The water in the tub will naturally acquire the temperature equating to the average surrounding temperature. During cold periods this may be colder than you like and here again the spa pack option can solve this problem.
The EcoPlus chiller unit that we supply has a cooling capacity of approx. 12,000 BTU/hr and the lowest operating temperature achievable is 55°F. The 12,000 BTU/hr is the cooling capacity with ambient temperature at 96°F or less. Above this the cooling capacity drops off.
Power needs to be provided (without the heating option) is through dedicated 15A 120v GFCI protected circuit. If both the chiller and heater are deployed electrical switching needs to ensure both heater and chillers are not “on” together at the same time
Benefits of Cold Plunge Tubs
The Chinese and Romans practiced cold therapy for 1000s of years. However more recently modern medicine has adopted the healing practices of cold water therapy. Normally cold water therapy is associated with an alternating hot and cold medium. Usually a steam room or a sauna room is used to warm the body before jumping in to the cold plunge pool for a few seconds or minutes.
Immersing your body in hot water and then cold water can be extremely beneficial. When you enter the tub the cold water quickly numbs your nerves surrounding the muscles and your joints. This cause the body to release endorphins which can aid in eliminating muscle and joint stress. The cold water also quickly causes the blood vessels to contract and reduces joint and muscle swelling. Another benefit often associated with cold plunge pools is to help increase the body's immune system. The cold water stimulates the body into producing a hormones called cytokines. Cytokines are widely known to boast the body's immune system and help to protect against virus and bacteria that can cause colds and flues. The restriction of the blood vessels is also known to be beneficial in lowering blood pressure.
