"The Hydro-Heater Food Rethermalizer/Bain Marie Heater is an electric appliance made in the USA. It features a stainless steel front and a powder coated body for durability. The low water cut-off system and electronic temperature monitor ensure safe and accurate heating. With a power of 6 kW, this heater is cULus and UL EPH Classified. It also meets ANSI/NSF 4 standards. The patented FR2 Hydro-Heater Food Rethermalizers / Bain-Marie Heaters are designed to supply temperature-controlled water to a sink mounted above the heater. They can heat or hold foods at safe-serving temperatures between 140°F (60°C) to 190°F (88°C) using ""free-flow"" technology for efficient operation. The unit includes a stainless steel front, powder coated body, low water cut-off system, convenient drain outlet, and clean-out caps. It features a tubular water chamber with a spiral heating element wrapped outside the flow tube to prevent direct contact with the water. Optional features include an auto-fill solenoid, remote mounted control, all stainless steel body and base, and a security package with Torx® screws and control cover. Accessories available for this heater include a flush kit with a flush hose, cleaning brush, stopper, and adapter. It is important to note that the Hatco FR2 series Hydro-Heater is specifically made for food rethermalizing, but it needs to be incorporated into a hot water bath rethermalizer. Hatco does not supply the vessel or the system for holding the food in the vessel. The FR2 unit attaches to the bottom of the vessel and supplies hot water. The vessel manufacturer is responsible for testing and listing the entire rethermalizing appliance according to NSF Standard 4."
