Heating cables are capable of maintaining required temperatures to prevent tanks of water, oils, chemicals, and other liquids from freezing and maintaining the required temperatures / consistency. The cables can also be used to heat silos with grains, sugars, and other such items.

ELEKTRA VC/VCD heating cables cannot be installed on tanks where the cables can be exposed to greases, oils, or other chemicals and where there is a risk of the temperature reaching more then 65oC .

To choose an appropriate heating cable, it is important to determine the possible heat losses of the tank. Such losses are dependant on the tank size, type, thermal insulation, the required temperature, and the minimum outside temperature.

For tanks with foundations, heat losses from the underside of the tank should be taken into consideration. The exact heat loss per tank varies due to the variety of shapes (cylindrical, rectangular, and conical), the type of foundation (with legs or solid), and any additional equipment required (access opening, ladders, level indicators).
