Product Description
The Cofi TRS 820/S is an oil transformer designed for ignition applications requiring high-voltage secondary output. It delivers 2x4000V secondary voltage from 220V primary input, making it suitable for industrial ignition systems and high-voltage equipment activation.
Used in
Common applications for COFIGas burner combustion — TRS 515 PC/S, TRS 610 PC/S, TRS 830 P/S ignition transformers for spark generation in small to large capacity gas-fired heaters and boilers.
Oil-fired heating systems — TRE 820/S1 oil-immersed transformer for reliable ignition in heavy fuel oil and light fuel oil burners in industrial plants.
Dual-fuel burner control — TRS 610 PC/S for burners switchable between gas and oil, requiring consistent high-voltage spark across both fuel modes.
Burner retrofit and maintenance — Replacement ignition transformers and mounting kits for aging or damaged combustion control systems in existing boiler houses.
High-voltage spark generation — TRG 1035/S dual-output transformer for complex ignition circuits requiring multiple spark electrodes or redundant ignition paths.
Panel-mounted combustion control — Column 12X38 and Spina cable assemblies for compact transformer installation in enclosed burner management control panels.
