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.
