Hatco FR-4B Description
By supplying hot, temperature-controlled water to a bain marie or food rethermalizer holding vessel, the Hatco FR-4B food rethermalizer and bain marie heater helps operators comply with NSF Standard 4, which requires food be heated to 165 degrees Fahrenheit within 2 hours. Its water temperature control enables operators to adjust temperatures between 140 and 190 degrees Fahrenheit, while its submerged heating element maximizes heat transfer because it contacts water directly. Water circulates continually to eliminate cold spots, and once water reaches the set temperature, an indicator light glows to notify employees. Its energy cutoff mechanism shuts the heater down if water temperature exceeds the setpoint to prevent unit damage.
This Hatco FR-4B food rethermalizer heater measures 9 inches wide by 171/8 inches deep by 121/4 inches high for use with a bain marie no longer than 6 feet. This unit includes standard 2-inch plated brass plumbing fittings for mounting into a holding tank, and its silver-gray hammertone body and rust- and corrosion-resistant stainless steel front are resilient enough to endure daily use in high-traffic kitchens. Its dual-reservoir design features a sump section separate from the heating compartment to trap and collect soil; this system's drain can be plumbed to an open-sight waste drain to simplify cleaning. For best results and efficient operation, this machine requires installation with a perforated water baffle, which is sold separately, and incoming water containing more than 3 grains of hardness per gallon (GPG) should be softened and treated before use.
