For  information on these heaters please see below.

Circulation Heaters
Wattco Ciculation Heater
Circulation Heaters also known as "in line heaters" made up of different materials depending on the  application. They are designed to heat pressurized circulating fluids to provide effective, controlled heating to water, oil, steam and other gases. Circulation heaters are composed of all-in-one units with a heater mounted inside an insulated tank. They are made of a flanged or a screw plug immersion heater that is inserted into a pressure vessel or a pipe body. These heaters have inlet and outlet piping where the liquid or gas goes through the tank in order to reach the desired temperature. 

Applications: Air and Similar Gases, Catalyst (re)Activation & Dehumidification, Caustic Solution Heating, Dry-Well Tank Heaters, Fuel Oil Preheaters, Heat Transfer Systems, Hydraulic and Heat Transfer Oils, Hydrocarbon gases, Lube Oil & Fuel Oil Heating, Lubrication & Conditioning Systems, Oil Suction Heaters, Process Air & Gas Heating, Process Chemical Reactors, Steam Superheating, Water-Glycol Solution Heating

Screw Plug Heaters
Wattco Scre Plug Heater
These heaters contain consist of hairpin tubular elements that are brazed or welded into a machined pipe thread fitting, which are then screwed directly through a threaded coupling in the tank wall or vessel, or installed in pipe. Screw plug heaters are an easy way to heat up solutions in smaller containers that also require controls.  

Applications: Clean Water, Light / Medium / Heavy weight Oils, Process Water, and Corrosive fluids

Flange Heaters
Wattco Flange Heater
 Flanged heaters use bent tubular elements that are brazed or welded onto a flange. Extra wiring boxes in which the electrical connections are fixed are provided with these heaters. Usually heaters have already been prefixed into flanges, our custom units can be welded on matching flanges that are mounted on a nozzle or tank wall. Wattco offers flanged heaters in varying kilowatts ratings, voltages, temperature ranges, sheath materials and so on. Flanged immersion heaters are one of the most widely used industrial heaters used. Compared to other oil heaters, they are easier to install, are specifically designed for use in pressurized vessels and more manageable. Typical applications include preheating different grades of oil, cleaning tanks and heat transfer.

  Cleaning and Rinsing Tanks, Hot Water Storage Tanks, Warming Equipment, Heat Transfer Systems, Preheating All Grades of Oil, Food Processing Equipment, Process Air, Boilers, etc...

Over the Side Heaters
Wattco Over the Side Heaters
Over the side immersion heaters are specifically designed that they can be installed in the upper portion of tanks. The substance to be heated is either below the heater or onto one side, (hence the name). The main advantages of this approach are that ample space that is left in the tank for other operations to take place and the heater can easily be removed when the required temperature is achieved within the substance. The heating element of an over the side process heater is usually made from steel, copper, cast alloy and titanium. A coating of fluoropolymer or quartz can be provided for protection.

Duct Heaters
Wattco Duct Heater
Duct heaters come in various sizes and dimensions to fit any compartment. There are three types of duct heaters available: open coil, tubular or finned tubular (heating elements that are either flanged or inserted in the duct).  Air duct heaters are primarily used in air flowing ventilation systems and comfort-heating applications. Process duct heaters are mainly used for industrial process heating applications (ovens that require re-circulated air or forced circulation).

Heat treating, Forced air comfort heating, Booster air heater, Air drying operations, Core drying, Air pre-heating, Air handling equipment, Fan coils, Terminal reheating, Multi zone reheating, Heat pump auxiliary systems, Return air heating, Resistor load banks, Annealing

Infrared Radiant Heaters
Wattco Infrared Radiant Heaters
Infrared radiant heaters are economic, efficient, and clean. These heaters are designed for comfort heating applications that require radiant heat indoor, outdoor, and exposed areas through direct infrared heat transfer.  Infrared industrial heating products use tubular heaters that reach high temperatures and radiate sufficient heat from overhead. Infrared heaters come in many different lengths and sizes. Waterproof housing is available to help protect terminals from humidity and moisture penetration and, are used in conjunction with digital or mechanical control panels. Wattco infrared heaters use high-grade stainless steel throughout along with protective wiring to help maintain lifelong usage.

Applications: Indoors such as retail locations, car washes, arenas. Outdoors such as patios, parking decks, or walkways.

Open Coil Heaters

Wattco Open Coil HeatersOpen coil elements are the most efficient type of electric heating element.Used primarily in the duct heating industry, open coil elements have open circuits that heat air directly from the suspended resistive coils. These industrial heating elements have fast heat up times that improve efficiency and are designed for low maintenance with inexpensive replacement parts. Open coil heater elements are made to fit inside standard 2’’ or 3’’ schedule 40 NPS pipe. Open coil heaters are also used in tank and pipe heating and/or metal tubing. A minimum clearance of 1/8’’ is required between the ceramic and the inside wall of the tube. Installing an open coil element will provide excellent and uniform heat distribution over a large surface area.

Applications: Tank heating, Tube heating, and Metal tubing

Tubular Heaters
Wattco Tublar Heaters
Tubular heating elements are the most versatile industrial heating solution for a large number of applications. These elements are factory-configured to almost any shape or size. Custom bending diameters and layouts can be made upon request. Tubular heaters are typically made using steel, stainless steel, Incoloy, inconel or titanium alloys. Tubular elements are often regarded as the foundation of all heating elements. These heating elements have a strong outer sheath to help protect the process heater from physical stress and uses high quality alloys to allow efficient heat transfer from resistance coil to your heating medium. Standard and custom made terminal pins allow for easy installation and maintenance. Wattco uses high quality magnesium oxide to allow for efficient heat transfer from resistive coil to your heating medium whether it is air, liquid or solid. Bending radiuses are designed with careful expertise to allow for optimal performance when meeting "form fit and function" within your application.

Applications: Heating metal parts, Heating liquids, Heating air and gases

Control Panels

Industrial control panels are used to regulate temperature and provide safety mechanisms to prevent overheating of your application and protect your heating elements. Control panels come in many different terminal boxes - standard NEMA 1 terminal boxes, dust proof boxes, waterproof boxes and explosion proof boxes for hazardous areas. These control panels contain digital controllers.contactors, relays, fuses, on/off disconnect switches, thermocouples or RTD sensors, temperature controllers and other components to help regulate your Wattco heater in a safe environment. Heating control panels are typically available for heaters generating at least 30 Amps to over 200 Amperes. Special accommodations can be made for systems that are over 200 Amperes. We can also provide NEMA 4 terminal panels. These panels are typically used for outdoor applications where concerns of moisture and humidity is a factor. All Wattco control panels come with circuit schematics as well as support.
