The source describes CNF unit heaters for maintaining main and auxiliary machinery-space temperatures while a vessel is alongside, including conditions near 0°C. Listed power options are 480 V, 460 V, 440 V or 220 V at 60 Hz, and 415 V, 400 V, 380 V or 220 V at 50 Hz. Confirm the supply required by the selected model.
The YYCNF(R) hot-water variant is described with an axial fan and a sheet-metal or stainless-steel enclosure. Listed heat-exchanger constructions include copper tubes with copper or aluminium fins and stainless-steel wound fins.
High- or low-temperature hot water is the stated heating medium for that variant. The electrical control cabinet may be integrated or supplied separately. Confirm the heating medium and model; steam-heater catalog pages are not interchangeable with CNF data.
