Electric Fuel-Oil Pre-heater protections

[martinrelayer]

Hi all,

We have Fuel-oil pumping station that is provided with two steam fuel-oil preheaters and one electric preheater. Everithing is on a normal pumping pressure of 12 bar, and the circulation temperature is 120°C, DCS controlled.
The electric pre-heater the only protection it has is an overpressure relief valve, and the heaters turn on and off with the tempreature controller of the main pumping line.
But I think there should be extra protection, for example a thermostat, or a pressure contact. My question is which are the standards (ASME or similar) regarding this kind of electric heaters, if there's any.

many thanks

Sans any standards, you might try the ELWA after sales dept. They supply fuel oil heaters.
