Exertherm

What Exertherm does

Exertherm (now marketed as Eaton Exertherm CTM following the May 2024 acquisition by Eaton Corporation plc) provides continuous thermal monitoring (CTM) solutions for critical electrical infrastructure. Founded in 1988 and headquartered in Harpenden, United Kingdom (with legal entity Exertherm Inc. registered in the United States), the company designs and manufactures permanently installed, hardwired thermal sensors that monitor electrical connections and joints in LV/MV switchgear, motor control centers, transformers, and bus duct systems on a 24x7 basis. The CTM system is positioned as an NFPA 70B-compliant alternative to periodic infrared thermography surveys, with a lifetime warranty and zero-maintenance guarantee on its hardwired sensor architecture, which avoids the cybersecurity exposure and battery-replacement overhead of wireless alternatives.

The product portfolio is built around a core CTM platform and specialized modules for bus duct, LV switchgear, MV switchgear, MCCs, dry-type transformers, and LV transformers, complemented by the Eaton ARM XL HMI module that enables Modbus TCP/IP data export and dry contact relay alarming. Sensors detect abnormal temperature rises outside configured parameters and trigger automated alerts, capturing time-series data that integrates with Eaton's Brightlayer software platform for digital asset management and IIoT applications. The company cites quantifiable outcomes including up to 70% more failures predicted in advance versus periodic inspections, approximately 30% lifecycle cost savings, and up to 25% increases in asset production output.

Exertherm operates exclusively through Eaton's global enterprise field sales organization following the acquisition, with quote-based pricing and multi-year contracts targeting data centers, oil and gas, industrial electrical infrastructure, and power utilities. Headcount is reported at 11-50 employees. Revenue, funding history, and ownership structure prior to the Eaton acquisition are not publicly disclosed.

Core offering

Exertherm designs, manufactures, and sells Continuous Thermal Monitoring (CTM) hardware systems — hardwired thermal sensors installed on electrical connections and joints in switchgear, motor control centers, transformers, and bus duct — that provide 24x7 always-on temperature monitoring and automated alerts to enable predictive maintenance of critical electrical infrastructure. Solutions are marketed and distributed under the "Eaton Exertherm CTM" brand following Eaton Corporation's May 2024 acquisition.

Product overview

Eaton Exertherm offers a unified Continuous Thermal Monitoring (CTM) platform that provides 24x7 sensor-based monitoring of critical electrical infrastructure. The portfolio includes specialized monitoring solutions for LV/MV Switchgear, Bus Duct, Motor Control Centers (MCC), Dry Transformers, and LV Transformers. The CTM system is positioned as a next-generation alternative to periodic infrared thermography, enabling condition-based monitoring practices as part of predictive maintenance and IIoT strategies. Key differentiators include hardwired sensor technology (avoiding wireless cybersecurity vulnerabilities), lifetime warranty, and integration with Eaton's hardware modules for data export via Modbus protocols.

Broad incumbents

• Schneider Electric: Schneider Electric operates EcoStruxure Power Monitoring Expert and connected switchgear solutions that include thermal/condition monitoring for LV/MV electrical infrastructure in data centers and industrial facilities. Directly comparable to Exertherm's CTM use cases but as part of a much broader electrical and software portfolio.
• Siemens: Siemens offers SIMATIC and SICAM-based power monitoring and electrical asset condition analytics across switchgear, MCC, and transformers in industrial and data center markets. Overlaps with Exertherm's electrical-infrastructure monitoring niche but within a far larger industrial-automation and digital-industries portfolio.
• ABB: ABB provides ABB Ability condition monitoring and connected switchgear for power distribution, targeting data centers, utilities, and industrial customers. Comparable application space to Exertherm CTM but bundled with ABB's full switchgear, drives, and digital portfolio.
• Teledyne FLIR: Teledyne FLIR is the dominant supplier of thermal imaging cameras used in periodic IR thermography surveys of electrical infrastructure. Directly comparable in end-customer (electrical inspectors) and application (thermal diagnostics of switchgear joints), but delivers periodic snapshots rather than continuous monitoring like Exertherm CTM.

Direct peers

• Fluke Corporation: Fluke is a market leader in handheld thermal imaging cameras and portable electrical test instruments used for periodic thermography inspections of switchgear — the exact inspection regime Exertherm CTM is designed to replace or supplement. Closely comparable buyer (electrical maintenance teams) and use case (thermal condition assessment of electrical connections).
• Megger: Megger manufactures electrical test, diagnostic, and condition-monitoring equipment for switchgear, transformers, and cables — overlapping with Exertherm's electrical-infrastructure condition monitoring niche and serving the same electrical-maintenance buyer persona.
• OMICRON Lab: OMICRON produces specialized diagnostics and monitoring solutions for electrical assets including transformers and protection systems, serving utilities and industrial operators. Comparable buyer profile and condition-monitoring use cases to Exertherm's CTM deployments in switchgear and transformer applications.
• Qualitrol (Iris Power): Qualitrol/Iris Power provides continuous condition monitoring sensors and analytics for rotating machines, transformers, and electrical infrastructure in utility and industrial markets. Closely comparable business model (sensor hardware + monitoring services for critical electrical assets) to Exertherm CTM.

Emerging players

• Banner Engineering: Banner Engineering sells industrial wireless condition-monitoring sensors and IIoT devices used in factory automation and electrical cabinets. Comparable end-market (electrical asset monitoring for predictive maintenance) and represents the wireless/IIoT-native competitive alternative to Exertherm's hardwired architecture.

Others

• Emerson (National Instruments / Branson): Emerson's NI and related industrial sensing businesses provide measurement, monitoring, and analytics hardware used in industrial condition-based maintenance programs. Adjacent ecosystem player to Exertherm's CTM data-capture and predictive maintenance positioning.
