CattleMaster fountains provide the best of both worlds: blending technology from traditional stainless steel units and the newest poly units, to provide a premier livestock waterer. Featuring thermostatically controlled heat for ice-free operation and Ritchie’s fast refill valve, Cattlemaster fountains will satisfy your herd’s hydration needs in any climate. The casing of the CattleMaster 840 is made from Ritchie’s heavy-duty, impact resistant polyethylene construction. The roto-molded construction is heavily insulated for energy efficiency and employs UV inhibitors for extended life.
