Treat musculoskeletal pain and recover faster with the use of heat therapy. The heat packs are heated uniformly inside the Whitehall Thermalator® that maintains constant water temperature. The tank body, lid, bottom and tank housing are all made from 304 stainless steel for years of trouble-free use. The color coded Thermal-Packs fit onto a sturdy stainless steel, vinyl coated wire rack. Inside the unit is a heating element and temperature sensor. Bottom feet keep the unit from slipping and marring the surface of the countertops. Units have a snap-off thermal protector to prevent overheating. A drain valve located on the back of most units makes them easy to clean. The Thermalator® is offered in sizes that accommodate 4, 6, 8, or 12 hot packs. All units have coved bottoms and are thermostatically controlled. T-4-S, T-6-S and T-8-S are supplied as countertop models. T-8-M and T-12-M are supplied as mobile models with 4 caster wheels (2 are locking).
