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 5⁄8-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.

Copper Sheath Immersion Heaters

Screw Plug Immersion Heaters with Copper Sheath for Heating Water.

Anderson-Bolds has been providing electric heating elements for heating water since 1934.  The first choice in heaters for industrial accounts to heat water tanks are screw plug electric immersion heaters.  The Screw Plug is easily installed via an NPT fitting in the tank wall.  The heater should be located near the bottom of the tank as when the heater is on it creates a convection within the tank.  The heater heats by conduction, or contact with the media.  But as water is heated or warmed by the immersed elements the warm water rises to the top of the tank.  The water below the heating element in a tank will not be heated.  Copper is the preferred sheath material for heating water.  Copper has the best heat transfer capability but also the lowest max temperature of about 750 degrees F.  Level control and temperature control can be critical to keeping the elements from burning out.  If the tank drains to expose the heaters and they are energized, they will fail quickly.  Air is a poor heat conductor and thus the elements will quickly heat up to over 350 degrees.  An element on an electric range is made of Incoloy, when the element turns red, the temperature is about 1250 degrees F.

Screw plug immersion heaters consist of tubular elements in a threaded hex plug. Some models are provided with a thermowell for the temperature control sensor and a variety of electrical enclosures for electrical connections. They screw directly through threaded openings in tank walls to heat liquids, viscous fluids, forced air, and gases by direct contact.

Chromalox MT and ARMT series Screw Plug Immersion heaters ( 2-1/2 inch plugs) with copper sheath are available in the below types or styles.

Screw Plug Immersion Heaters can have NEMA 1 housing or general purpose housing for in plant use.
Screw Plug Immersion Heaters can have Moisture resistant housing for wet locations, indoors or outdoors.
Screw Plug Immersion Heaters can have Explosion Resistant housing for hazardous rated areas.

Screw Plug Immersion heaters can also have Thermostats built into the enclosure.  the Thermostats can handle up to 22 AMPS.  If three phase or above 22 amps, a three pole contactor will be required to switch on the heating elements.

Screw Plug heaters with integral thermostat, 0-100 degrees F adjustability.
