Cuenod

FranceBurners & Combustion

Cuenod is a manufacturer of combustion control electrodes and ignition systems, specializing in flame-detection and ignition hardware for industrial burners. The product line centers on electrode assemblies, ionization probes, and interconnect cables designed for integration with burner control packages across a range of firing capacities. Primary electrode families include the C-series (C3G, C4, C5G, C7, C10, C14, C18, C20, C22, C24, C30), DX electrodes, and NC-series variants, each specified for particular burner frame sizes and combustion chamber geometries. Ignition electrodes and ionization probes are supplied as complete assemblies—combining the detection rod, probe body, and pre-terminated cable—to reduce field assembly time and ensure impedance matching with control module inputs. Ionization cables (designated TGF and TEF variants with length codes such as LG 380 or LG 530) connect probes to flame-supervision terminals on the burner management system. Each electrode type is rated to withstand the thermal and electrical stresses of continuous or intermittent burner duty; specifications include operating temperature ranges, probe resistance characteristics, and cable shielding standards appropriate for industrial HVAC, process heating, and power-generation boiler applications.

About Cuenod

Cuenod is a manufacturer of combustion control electrodes and ignition systems, specializing in flame-detection and ignition hardware for industrial burners. The product line centers on electrode assemblies, ionization probes, and interconnect cables designed for integration with burner control packages across a range of firing capacities. Primary electrode families include the C-series (C3G, C4, C5G, C7, C10, C14, C18, C20, C22, C24, C30), DX electrodes, and NC-series variants, each specified for particular burner frame sizes and combustion chamber geometries.

Ionization cables (designated TGF and TEF variants with length codes such as LG 380 or LG 530) connect probes to flame-supervision terminals on the burner management system. Each electrode type is rated to withstand the thermal and electrical stresses of continuous or intermittent burner duty; specifications include operating temperature ranges, probe resistance characteristics, and cable shielding standards appropriate for industrial HVAC, process heating, and power-generation boiler applications.

3G Electric supplies Cuenod's full range of electrodes and cables, supporting maintenance and retrofit projects for plant engineers and procurement specialists. The product portfolio covers ignition electrodes for direct spark ignition, ionization probes for flame rectification sensing, and replacement cables with defined lengths and shielding to match existing burner control wiring. Cuenod's design approach emphasizes modularity: electrodes are available as standalone components or as pre-assembled units with cables, allowing for straightforward replacement without custom fabrication. The C-series electrodes are differentiated by physical dimensions—electrode rod diameter, insulator length, and mounting thread—to fit specific burner brands and models, while DX and NC variants address compact or high-temperature combustion chambers. Technical documentation for each SKU includes resistance values, maximum operating temperature, and cable capacitance, enabling engineers to verify compatibility with their burner management system's input requirements.

For 3G Electric customers, Cuenod components are sourced as genuine manufacturer parts, ensuring dimensional accuracy and material consistency. The electrodes use ceramic insulators and nickel-alloy rods to resist thermal cycling and corrosive flue gases, with typical temperature ratings exceeding 1000°C for the sensing tip. Ionization cables are constructed with silicone or fiberglass insulation and braided shielding to minimize electromagnetic interference, critical for reliable flame signal transmission in industrial environments. Whether for routine preventive maintenance or emergency breakdowns, 3G Electric maintains inventory of common Cuenod electrode types and cables, with global shipping to support facilities outside Singapore. The combination of Cuenod's specialized combustion components and 3G Electric's distribution network provides a dependable supply chain for burner upkeep and upgrades.

Frequently asked questions

Common questions about Cuenod from 3G Electric.

What is the difference between Cuenod C-series and DX electrodes?

Cuenod C-series electrodes (e.g., C3G, C4, C5G, C7, C10, C14, C18, C20, C22, C24, C30) are designed for specific burner frame sizes and combustion chamber geometries, with variations in rod length, insulator diameter, and mounting thread. DX electrodes are a separate family, typically used in compact burner designs where space is limited. The electrical characteristics—such as resistance and capacitance—differ between series, so selecting the correct type is critical for proper flame detection. Always verify the burner model and consult the Cuenod cross-reference to ensure compatibility.

How do I choose the correct Cuenod ionization cable length (e.g., LG 380 vs. LG 530)?

The cable length code (e.g., LG 380, LG 530) indicates the overall length in millimeters. Choose the length that matches the distance between the ionization probe and the burner control terminal. Using an incorrect length can lead to signal attenuation or physical routing issues. Cuenod offers TGF and TEF cable variants; TGF is typically for standard applications, while TEF may have enhanced shielding or temperature rating. Always match the cable type to the electrode model and the control system's input specifications.

Can Cuenod ignition electrodes be used as replacement parts for other burner brands?

Cuenod electrodes are designed to meet specific dimensional and electrical specifications, which may align with certain burner models from other manufacturers. However, it is not guaranteed that a Cuenod electrode will fit or function correctly in a non-Cuenod burner without verification. Check the electrode's thread size, rod length, and resistance against the original part's specifications. If in doubt, consult the burner manufacturer's documentation or contact 3G Electric for technical guidance.

What is the typical lifespan of a Cuenod ionization probe?

The lifespan depends on operating conditions, including temperature, fuel type, and cycling frequency. In continuous-duty industrial burners, a Cuenod ionization probe may last several thousand hours, but in intermittent operation with frequent starts, wear can be faster. Regular inspection for electrode erosion, insulator cracking, or carbon buildup is recommended. If the flame signal becomes weak or erratic, replace the probe assembly to maintain reliable flame supervision.

Are Cuenod electrode assemblies supplied with pre-terminated cables?

Yes, many Cuenod ignition electrode and ionization probe assemblies come with pre-terminated cables, as seen in SKUs like ELC10058 (for C3G) and ELC10060 (for NC4/6/9). This reduces field assembly time and ensures proper impedance matching. For standalone electrodes, separate cables (e.g., TGF or TEF) are available. Always confirm whether the SKU includes the cable or if it must be ordered separately.

What are the temperature ratings for Cuenod electrodes?

Cuenod electrodes are designed to withstand high temperatures typical of combustion environments. While specific ratings vary by model, the sensing tip is generally rated for continuous operation above 1000°C, with ceramic insulators providing thermal and electrical isolation. The cable insulation is rated for lower temperatures (typically up to 200°C) and should be routed away from direct flame contact. Refer to the technical datasheet for each electrode model for exact limits.
