Sunrod TOH 1t/7bar

The Sunrod Sunrod TOH 1t/7bar is a thermal-oil heater. It is normally installed in the machinery space connected to circulation pumps, expansion tank and heat consumers. It is designed for heating of a closed thermal-fluid circuit for cargo, fuel or process duties. In operation, the fired or waste-heat source transfers energy into circulating thermal oil instead of producing steam. The supplied entry states the intended fuel or liquid service as HFO/MDO; this information is retained unchanged. Compared with neighbouring models, the relevant differences are heat duty, flow resistance, thermal-fluid volume, burner/exhaust arrangement and controls; these must be confirmed from the installed documentation rather than inferred from the model designation alone. Service and survey attention should concentrate on circulation, thermal-fluid condition, heater leakage, expansion system, overtemperature trips and fire safety. For exact ratings, dimensions, tolerances, test limits and model-specific settings, refer to the manufacturer documentation for the exact figure.

Common failures & inspection points

Heat-source or burner failure caused by fuel, ignition, exhaust-flow or control faults, noticed as failed start, trip or reduced heat production
Low or unstable water/fluid circulation caused by pump, level-control or valve faults, noticed as alarms, local overheating or loss of output
Heating-surface fouling caused by soot, scale or deposits, noticed as reduced efficiency, higher exhaust temperature or increased pressure drop
Tube, coil or pressure-part leakage caused by corrosion, erosion, scale or thermal stress, noticed as water/fluid loss, steam leakage or contamination of the gas side
Safety/control instrumentation failure caused by sensor, valve, actuator or interlock faults, noticed as unstable operation, nuisance trips or failed functional tests

Service & Maintenance

Inspect pressure parts or heater coils, heat-source/burner and refractory where applicable, gas-side cleanliness, circulation/feed systems and water or thermal-fluid condition. Verify level, pressure, temperature, flow, safety valves and shutdown/interlock functions applicable to the design. Review treatment, blowdown, soot-cleaning and operating records and use manufacturer/class procedures for pressure tests.

Replacement Parts

Carry approved gaskets, valve service parts, relevant pump seals/bearings, temperature/pressure/level sensors and heat-source-specific spares such as burner ignition/flame components or soot-cleaning parts. Pressure-part repair materials should only be used under approved manufacturer and class procedures.
