Control Specialists

What Control Specialists does

Control Specialists LLC is a regional industrial services company headquartered in Evansville, Indiana, with a secondary office in Calvert City, Kentucky. Founded in 1983 and now operating as a subsidiary of Relevant Solutions (acquired in 2026), the company provides process instrumentation, combustion and control systems, and specialized industrial services to industrial customers across the Indiana-Kentucky region. Its service portfolio covers turn-key system integration combining instrumentation, controls, valves, PLCs, and burners; UL 508A-certified custom panel fabrication; in-shop and on-site calibration; NFPA combustion safety checks; troubleshooting and repair; and start-up, commissioning, and PLC programming support. It also operates as an authorized distributor for leading industrial brands, distributing parts alongside its service work.

The company's core technology is conventional industrial automation and combustion control — PLCs, instrumentation, valves, and burners integrated into customer systems — with proprietary capability concentrated in its UL 508A panel shop and NFPA-compliant combustion servicing. It does not maintain a software platform, AI/ML capabilities, APIs, or mobile applications; the technical differentiation is in hands-on engineering, certified fabrication, and field service execution. No patents, no proprietary data assets, and no AI tooling are disclosed.

The business model combines multiple revenue streams: authorized parts distribution (transaction-based), technical services such as calibration and NFPA checks (professional services / recurring), turn-key system integration (project-based), and UL 508A panel fabrication (hardware/services hybrid). Pricing is quote-based B2B with no public pricing. The go-to-market is sales-led, with direct field engagement, phone-based inside sales, and a light digital presence (website, Facebook, LinkedIn, downloadable Line Card). Geographic reach is explicitly regional — Indiana and Kentucky — with no claim of national or global footprint.
