Cargo Tank Heating System · Tanker Cargo Systems
Wärtsilä Cargo Heating Unit CHU — Tanker Cargo Systems. As a Cargo Heating System, it is normally installed in cargo tanks and the associated steam, thermal-oil or heating-medium piping and control arrangement. In that role, its primary purpose is to maintain or raise cargo temperature so that viscosity, pumpability or process requirements remain suitable for cargo handling. Cargo-heating arrangements differ in coil layout and heating medium, but all rely on leak-free heat-transfer surfaces and controlled flow through the tank heating circuit. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.

What our service work and the manufacturer documentation say about keeping this model running.
Inspect heating-medium valves, drains, traps, coil integrity, temperature indication and accessible piping. Trend cargo temperature response and investigate unexplained heating-medium losses. Confirm isolation and leak-testing arrangements follow the vessel cargo procedure. Refer to the manufacturer and vessel documentation for the exact figure for pressure, temperature and test criteria.
Carry valve and trap service kits, gaskets, temperature sensors, actuator parts and approved tube or coil repair provisions where permitted.
