Watlow Fire Bar Heaters and Elements

Anderson-Bolds sells Watlow Fire Bar Heaters and Elements


Watlow’s FIREBAR heaters with flat surface technology provide faster heat-up and recovery times than standard round tubular heaters. Their unique shape minimizes coking and oil degradation, and enhances the flow of the oil past the element’s surface, helping to pull heat away from the heater sheath. The heater lasts longer because it runs at a significantly lower sheath temperature than an equal watt density round tubular. This also prolongs the life of the oil or shortening and reduces costs from frequent changing.
Because of its design and geometry, a FIREBAR heater will heat viscous fluids from ambient temperature faster than tubular elements with the same wattage and at a lower sheath temperature. Other advantages of the FIREBAR heater’s flat surface technology include:

Buoyancy force – The flat geometry of the FIREBAR heater creates the physical principle of buoyancy force that lifts the oil into the work zone and makes this product superior to round tubular heaters.

Smaller dimension normal to the flow – The element’s width or thickness is 0.235 in. (5.9 mm). Compared to a 0.430 in. (11 mm) round tubular element, this relative thinness further reduces drag on liquids or gases flowing past the heater, resulting in better heat transfer, quicker heat up and lower sheath temperature.

Reduced watt density - The surface area per linear inch of a FIREBAR is 70 percent greater than the 0.430 inch (11 mm) diameter round tubular element. The FIREBAR, is nearly 13 percent greater. This translates into longer heater life with optimum performance.

The lower profile design of the 58-inch FIREBAR heater packages 13 percent greater wattage than an equal length, commonly used tubular heater. This heater is available in two-coil construction, while the one-inch FIREBAR heater offers three-coil, three-phase construction.
Perfect for oil immersion applications, such as open and pressure fryers or smaller countertop fryers.
