In In-direct heating type tanks-cylindrical in shape& horizontal in position, the bitumen is heated by circulating hot thermic oil through its heating coil. A thermic oil heater with oil fired burner heats the thermic oil & this hot oil is circulated through the heating coil inside the bitumen tank by an oil pump on heater. A single heater can easily heat nos. of tanks as required in continuous process. The temperature of oil is very well controlled by an auto thermostat on heater and so, bitumen never gets over-heated. Thus, the quality of bitumen (viscosity) never gets deteriorated/spoiled in this kind of indirect heating system. Fuel consumed to heat every ton of bitumen is also less compared that for a direct heating system.
Tanks capacity available is 30, 40 & 50 tons.
Bitumen tanks are supplied of ‘O’/’U’ – shaped horizontal in position as per customer’s choice. An oil-fired auto control pressure jet burner is mounted on each tank to heat the bitumen to the desired temperature. In this direct-heating type tanks, the bitumen is heated by firing the burner into heating coil made of steel pipes.
Tanks capacity available is 10, 15, 20, 25 tons.
