Kromschröder CM222 Series Technical Notes

The Kromschröder CM222 series represents a core product line within Elster Group's industrial combustion control portfolio, deployed extensively across global heavy industry sectors including petrochemical refineries, chemical processing plants, power generation facilities, and industrial furnace operations. Manufactured in Germany to DIN EN 298 and EN 230 standards, the CM222 family provides programmable burner sequence control with integrated flame supervision, making it a reference-class component in process burner management systems (BMS). Installations of CM222 units are documented in facilities across Europe, the Middle East, and Asia-Pacific, where long equipment lifecycles (15–25 years) create sustained demand for spare parts and replacement modules.
