TEMPCO
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.
