Watlow BLNF18C5 FIREBAR 20kW 480VAC Three-Phase Screw Plug Immersion Heater

Description

The Watlow Industries BLNF18C5 is a FIREBAR immersion heater designed to transfer electrical heat directly into compatible industrial liquids and process media. Watlow part number BLNF18C5 belongs to the FIREBAR heater family, which uses a flat heating-element design to increase the heat-transfer surface area compared with conventional round tubular elements. Its construction is intended for industrial process heating applications where efficient heat transfer and controlled liquid temperatures are required.

Technical Specifications

Information About BLNF18C5

The BLNF18C5 is a Watlow FIREBAR immersion heating element developed for direct-contact industrial heating applications. The FIREBAR series uses a flat tubular element geometry that provides a broad heat-transfer surface and supports heat distribution across the surrounding process medium. This heater type is used in compatible tanks, reservoirs, and industrial heating assemblies where electrical energy is converted into heat through a resistance element. Its suitability for a particular installation depends on the element's electrical ratings, sheath material, mounting configuration, and compatibility with the heated medium.

Key Features:

• FIREBAR Technology: Flat tubular heating-element design provides an increased heat-transfer surface compared with similarly sized conventional round elements.

• Immersion Heating: Designed to transfer thermal energy directly into compatible liquids or process media.

• Electric Resistance Operation: Converts electrical energy into heat through an internal resistance heating element.

• Industrial Construction: Intended for integration into industrial process heating equipment.

• Heat Transfer Geometry: Flattened element profile provides a broad surface for transferring heat to the surrounding medium.

• Process Temperature Control: Can operate with an appropriately rated external temperature controller and switching device.

• Application Flexibility: Suitable for compatible liquid heating systems, tanks, and process equipment.

• Element Compatibility: Installation requires verification of the heater sheath material against the process medium.

• Electrical Integration: Requires supply voltage and circuit protection matched to the heater's nameplate ratings.

• Replacement Identification: BLNF18C5 provides the specific part reference for maintenance and equipment servicing.

The BLNF18C5 delivers the reliability and precision required for industrial immersion heating, liquid temperature maintenance, and controlled thermal processing applications.
