Mineral Insulated Heating Cable for Heat Trace for Biodiesel is systematical solution to provide heat accompaniment in the process pipes to prevent an decrease in the viscosity of the products, phase shifts and guarantees the correct operation of the safety and fire fighting systems as biodiesel is a synthetic liquid biofuel obtained from natural lipids such as vegetable oils or animal fats.

The biodiesel is made by an industrial esterification and transesterification processes. The transesterification process consists of combining normal vegetable oil with a light alcohol, normally methanol.

 

The solidifacion of oil or raw materials could cause non-desired production stoppages. The correct operation of fire fighting systems is required.

Biodiesel allows CO2 reduction between 25 to 80% and greenhouse reduction generated by transport.

Freezing Prevention for metal gutters and downpipes	49
Freezing Prevention for non-metal gutters and downpipes	16
Vessel and piping process temperature maintaining	59
Freezing Prevention for metal containers and pipes	59
Metal roof snow-melting	49
High-density polyethylene outer sheathed copper sheathed heating cable (MIHC)
Freezing Prevention for metal containers and pipes	26
Freezing Prevention non-metallic containers and pipes	13
Snow melting on asphalt slopes	82
Non-metallic roof ice or snow melting	26
