COMPACT HEATER ENABLES VERSATILE HEATING SYSTEM DESIGN

FIREROD water immersion heaters are ideal for replacing large screw-plug immersion heaters. Because of its compact size the product can be very versatile when designed into a heating system.

These water immersion heaters come complete with a brass 3⁄4 inch National Pipe Thread (NPT) double threaded fitting, which allows you to add conduit boxes. Also, FIREROD immersion heaters are sealed at the lead end with a silicone rubber seal.

Solid copper leads, with silicone rubber sleeves, are provided for unrestricted wiring. These units are recommended for immersion in water or 90+ percent water soluble solutions.

• Nickel-chromium resistance wire precisely centered in the unit ensures even, efficient distribution of heat to the sheath
• MgO insulation compacted to the proper density results in high dielectric strength and contributes to faster heat-up
• Alloy 800 sheath resists corrosion from water
• Metallurgically-bonded conductor pins for trouble-free electrical continuity
• 240 and 480VAC voltage allows flexibility in wiring the heater for use in your particular applications

IDEAL FOR PROCESS AIR HEATING APPLICATIONS REQUIRING HIGH TEMPERATURES

Watlow manufactures high-temperature tubular heaters to bridge the gap between standard tubular heaters and Watlow MULTICELL™ heaters. This high temperature heater is well suited for process air heating applications in excess of 1300˚F (704˚C), resulting in a maximum sheath temperature of 1800˚F (983˚C). Controlled lab testing between the new design and current tubular designs shows an increase in life of approximately 50 percent.

The high-temperature heaters consist of an engineered tubing with an outer sheath of Alloy 600 and a special internal construction. The outer sheath offers high temperature capabilities, reduced oxidation as well as corrosion resistance.

The tubular heater offering is available in 0.430 and 0.375 inch diameters that are configurable either as formed tubulars or process heaters. The tubular heaters can also be welded to flanges and plates for mounting purposes. Maximum sheath length available is 275 inches for the 0.430 inch and 0.375 inch diameters. The factory should be contacted for longer sheath lengths.

• Alloy 600 sheath material and a special internal construction maximizes performance and corrosion protection in tough applications
• Dual-ended termination Installs into flanges and screw plugs similarly to standard product configurations
• Bendable in standard formations makes the heater easy to apply in a wide variety of applications

Watlow plate flanged heaters are easy to install and maintain. These flanged heater products are designed for heating heat transfer fluids, medium and lightweight oils and water in tanks and pressure vessels. Plate flanged heaters are ideal for applications requiring low to medium wattage requirements.

Watlow plate flanged heaters are made with WATROD tubular elements that are brazed or welded to the flange. Stock plate flanged heaters are supplied with general purpose or moisture-resistant terminal enclosures.

• Rapid ship program minimizes downtime
• Direct replacement for many OEM mold temperature control units provides a single-source supplier for many OEM application
• ANSI compatible 2 and 2½ inch flanges for appropriate heater size-to-application fit
• Standard, general purpose, or moisture resistant terminal enclosures to easily control access to wiring

AGENCY CERTIFIED TUBULAR HEATERS IDEAL FOR HEATING LIQUIDS, GASES, TANKS AND PRESSURE VESSELS REQUIRING HIGHER KILOWATTS

Watlow flanged immersion heaters are easy to install and maintain. Designed for heating liquids and gases in tanks and pressure vessels, flanged immersion heaters are ideal for applications requiring higher kilowatts.

Watlow flanged immersion heaters are made with WATROD or FIREBAR tubular elements brazed or welded to a flange. Stock flange heaters are equipped with a general purpose terminal enclosure.

Flanged immersion heaters, with FIREBAR elements, also answer the need for liquid immersion applications requiring high kilowatts in small tanks. The FIREBAR element’s unique flat surface geometry packs more power in a smaller bundle, with lower watt density, making it especially well-suited for petroleum-based liquid heating applications.

• UL® and CSA component recognition
• ANSI and ANSI compatible 2, 2½, 3 thru 48 inch flanges
• All units are inspected and/or tested to ensure element-to-flange pressure seals do not leak
• Integrel thermowells provide convenient temperature sensor insertion and replacement without draining the fluid being heated
• Standard, general purpose terminal enclosure for easy access to wiring
