CEM Service Group

What CEM Service Group does

CEM Service Group is a privately held, US-based industrial systems integrator specializing in Continuous Emission Monitoring Systems (CEMS) and related field services for regulated heavy-industry customers. The company designs, assembles, installs, and services the proprietary CEMSentry™3000 platform, which integrates third-party gas analyzers (Siemens, Teledyne API, Thermo Environmental, California Analytical, Ohio Lumex, Servomex, Gasmet FTIR), sample conditioning, heated umbilical lines, temperature-controlled industrial shelters, and a PLC/Windows-based Data Acquisition System (DAS) into compliance-grade monitoring solutions. Specialized configurations address corrosive gas streams (extractive dilution), ammonia slip on SCR-equipped power plants (tunable laser diode), and combustion efficiency (in-situ oxygen).

The customer base is diversified across vertical end-markets including power generation and utilities, petrochemical and refining, cement and mineral processing, pulp and paper, pharmaceutical and specialty manufacturing, environmental remediation and waste management, environmental engineering consultants, printing/coating, and US military installations. Sales are executed exclusively through direct enterprise field sales and inside sales — toll-free phone, dedicated sales/service email, and a website storefront — with no reseller or distributor channels. Revenue is generated across multiple streams: CEMS equipment sales (hardware), turnkey installation services (professional services including structural and electrical engineering, welding, custom fabrication, commissioning, training), preventive and emergency field maintenance, EPA quality assurance auditing, rental/lease of heated sample lines and mobile analytical trailers for RATA testing, spare parts and upgrades, and CEMS consulting/protocol preparation.

The business model is project-based and quote-driven with no publicly disclosed pricing. The firm is small (1-10 employees) operating from Bedminster, Pennsylvania, with primarily US-centric engagement plus selective international reach (China named). Customer relationships are characteristically long-tenured — some spanning nearly two decades — supported by recurring maintenance contracts and quarterly compliance audits that generate predictable aftermarket revenue on top of lumpy one-time system sales.
