The Hatco FR-9B 9KW Food Rethermalizer is a game-changer for commercial kitchens and restaurants looking to maintain food quality and consistency. Designed for bain marie holding tanks, this 9-inch-wide, 3-phase (208V) unit delivers powerful, uniform heating with a permanently submerged element, ensuring precooked foods are rethermalized and held at optimal serving temperatures (140-190°F). Its dual-reservoir configuration—with separate heating and sump compartments—simplifies cleaning and sanitizing, while the stainless steel front resists rust and corrosion, making it built to last in high-volume environments. Whether you're operating a buffet, catering company, or high-end restaurant, the Hatco FR-9B provides reliable performance and energy efficiency, helping you maintain food safety and customer satisfaction. The included 2-inch plumbing fittings allow for easy installation, and its energy cutoff mechanism ensures safety by shutting off power in case of unexpected temperature rises. For restaurants dealing with water hardness over 3 grains per gallon (GPG), it's recommended to treat and soften water before use to protect the unit's longevity.
