TEMPCO

TEMPCO Electric Heater Corporation is a manufacturer of electric heating elements, temperature controllers, and thermal components for industrial and commercial applications. Founded in 1972 and based in Wood Dale, Illinois, the company produces a broad catalog that includes immersion heaters, cartridge heaters, strip heaters, tubular heaters, radiant heaters, band heaters, and temperature control devices. TEMPCO products are used across process heating, freeze protection, comfort heating, and equipment original equipment manufacturer (OEM) applications. The product families cover a wide range of electrical ratings and physical configurations: immersion heaters with screw-plug or flange mounts, watt densities from under 20 W/in² to over 100 W/in², sheath materials such as copper, steel, and stainless steel, and voltage options from 120 V to 480 V AC and beyond. Temperature controllers like the TEC-4300 series offer 1/4 DIN panel-mount packaging, PID control, universal sensor inputs, and relay outputs for alarms or secondary control. Radiant strip heaters are available in weather-resistant constructions for outdoor spot heating, with single-phase ratings from 1,200 W at 120 V to 6,000 W at 480 V. 3G Electric supplies the TEMPCO line with a focus on technical procurement: each listed part includes manufacturer part numbers, electrical specifications, and dimensional data where available. The catalog spans replacement elements for existing process heaters, complete screw-plug immersion assemblies, and control instruments. For plant engineers and maintenance teams, this means access to components that match common tank, vat, duct, and open-area heating requirements without custom engineering. 3G Electric supports the line with datasheet access, cross-reference assistance, and global logistics for both standard and hard-to-find TEMPCO items. Whether the requirement is a 7,500 W three-phase screw-plug immersion heater with a 2 in NPT brass fitting, a hairpin replacement element for a TRH50010 process heater, or a weather-resistant radiant strip heater for a loading dock, the TEMPCO range covers these categories with published specifications. The brand’s emphasis on standard mounting geometries and electrical ratings makes it straightforward to specify replacements or new installations. 3G Electric maintains inventory and sourcing channels for TEMPCO products, serving industrial buyers who need documented part numbers and consistent build quality. The product data provided for each SKU includes voltage, wattage, amperage, sheath material, connection type, and control compatibility, allowing procurement and engineering teams to verify fit before ordering. This catalog page reflects the TEMPCO product families currently available through 3G Electric, with an emphasis on immersion, radiant, and process heating elements as well as digital temperature controllers. For applications requiring precise temperature regulation, the TEC-4300 controller provides PID logic and dual relay outputs in a compact 1/4 DIN package. For direct liquid heating, screw-plug immersion heaters offer a sealed, threaded connection and copper sheaths for compatibility with water and select process fluids. Radiant strip heaters address outdoor or semi-exposed areas where convective heating is impractical. Replacement elements extend the service life of existing TEMPCO process heaters. Together, these families represent the core of TEMPCO’s electric heating offering as carried by 3G Electric.

Frequently asked questions

Common questions about TEMPCO from 3G Electric.

What are the electrical specifications of the TEMPCO TEC-4300 temperature controller?

The TEMPCO TEC-4300 is a 1/4 DIN digital temperature controller with PID control mode and a universal sensor input. It accepts 90 to 264 V AC input voltage and provides two 2 A relay outputs plus two 2 A relay alarm outputs. The universal input supports common thermocouple and RTD types, allowing one controller model to serve multiple sensor configurations. The dual relay outputs can be used for heating and cooling control or for alarm signaling. Panel mounting follows the 1/4 DIN cutout standard. For detailed wiring diagrams and sensor compatibility, refer to the manufacturer datasheet.

What is the watt density and connection type of the TEMPCO screw-plug immersion heater (MPN TSP02089)?

The TEMPCO screw-plug immersion heater with MPN TSP02089 is rated 240 V AC, 7,500 W, three-phase, with a 2 in NPT brass screw plug and copper sheath. Watt density is 59.06 W/in². The 2 in NPT connection is a common tank fitting, and the copper sheath is suitable for direct heating of water and compatible liquids. The three-phase configuration distributes load across three conductors, which can reduce current per line compared to single-phase alternatives. This heater is intended for direct immersion in tanks, vats, and process vessels where the fluid is compatible with copper.

Which TEMPCO process heater uses the hairpin bend replacement element (MPN THE09186)?

The TEMPCO hairpin bend replacement element with MPN THE09186 is designed for use with TEMPCO model TRH50010 electric process heaters. It is rated 240 V AC and 1,800 W. The hairpin bend geometry allows the element to be inserted into a process heater housing or duct, where it transfers heat to air or process gas. Replacement elements are used to restore heating capacity without replacing the entire heater assembly. When ordering, verify the model number of the existing process heater and the element’s voltage and wattage match the original specification.

What are the available ratings for TEMPCO weather-resistant radiant strip heaters?

TEMPCO weather-resistant radiant strip heaters are available in several single-phase ratings for outdoor use. Examples include 120 V, 1,200 W, 10 A (MPN 2LRV3); 240 V, 1,200 W, 5 A (MPN 2LRV4); 240 V, 5,000 W, 20.83 A (MPN 2LRV9); 480 V, 3,600 W, 7.5 A (MPN 2LRV8); and 480 V, 6,000 W, 12.5 A (MPN 2LRW3). Each unit has one heating element and a weather-resistant construction for outdoor spot heating. These heaters are typically mounted overhead or on walls to direct infrared heat to loading docks, outdoor work areas, and equipment zones.

What sheath materials are available for TEMPCO immersion heaters?

TEMPCO immersion heaters are available with sheath materials including copper, steel, and stainless steel. Copper sheaths are commonly used for water and non-corrosive liquids because of their thermal conductivity. Steel sheaths offer higher temperature capability and are used in some oils and process fluids. Stainless steel sheaths provide corrosion resistance for more aggressive fluids or sanitary applications. The screw-plug immersion heater with MPN TSP02089 uses a copper sheath. When selecting a sheath material, consider fluid compatibility, operating temperature, and watt density to avoid premature failure from corrosion or scaling.

How does 3G Electric support TEMPCO product selection and procurement?

3G Electric provides TEMPCO product data including manufacturer part numbers, electrical specifications, and dimensional information where available. For buyers, this means the ability to cross-reference existing TEMPCO part numbers, verify voltage and wattage ratings, and confirm mounting configurations before ordering. 3G Electric sources TEMPCO items globally and can assist with identifying replacement elements or controllers that match an existing installation. The catalog includes immersion heaters, radiant strip heaters, process heater replacement elements, and temperature controllers. For items not listed, 3G Electric can often source additional TEMPCO part numbers on request.
