These innovative De-Icers have proven themselves to be very effective in keeping a constant water supply to livestock in very harsh conditions of cold weather. No more chopping ice off to get the water to flow. They are thermostatically controlled to keep the water above freezing without heating the water up and are perfectly safe for use in any of our plastic  products. These heaters have a special high temperature coating on them to prevent lime build up. This coating prolongs the life of the unit and dissipates heat more effectively and efficiently while saving you time and money.
