Battlecreek Equipment manufactures Thermophore moist heat therapy systems. The Thermophore was developed 80 years ago and uses moisture from the air to create deep, penetrating moist heat without needing additional moisture added. It comes in classic and one-touch models in different sizes. The classic has a momentary switch while the one-touch has a 20-minute automatic shutoff timer for safety. Thermophores provide better temporary pain relief than ordinary heating pads due to their ability to deliver high heat penetration.
