Model 8710 Polar Booth series includes an insulated all-weather booth with an integral hot water supply and tempered blending system. Haws offers 119 and 325 gallon storage capacities, as well as an instantaneous steam heat exchanger as options. All tempered water systems incorporate fail-safe features, including anti-scald protection and full flow cold water bypass. It is ideal as a complete stand-alone system, or as a feeder to other remote polar booth substations. Multiple shower systems may be connected with heat-traced lines or pump driven recirculating lines.
