Used in

Common applications for CBM
Industrial boilers — CBM circulation pumps (mod. CM 30W) and solenoid valves (ELV series) for heating-loop control and pump staging.
Burner systems — CBM oil nozzles (FLU atomizer types), electrodes (ELC 200 mm), and solenoid coils (ELV 230V AC) for combustion ignition and flame supervision.
Plant maintenance and retrofit — CBM cable glands (CLI M25), motor couplings (ACC type D), and small-radius fittings (RAC 90°) for equipment reconfiguration and sensor integration.
Boiler water treatment — CBM chlorine test kits (DET free+combined) for feedwater and circulating-water quality monitoring in closed-loop systems.
Pump and motor assembly — CBM couplings, fittings, and cable glands for assembly and rewinding of industrial motors, circulation pumps, and auxiliary equipment.
