Fuel Tank Heater Termodiesel


Protech s.r.l. has, for several years now, been a leader in the production of diesel filter heaters. The company has recently begun production of the TERMODIESEL Tank Heater, designed and developed to heat diesel fuel in the tanks of trucks, site vehicles, power generators etc. to prevent the crystallisation of paraffin in diesel fuel under harsh climatic conditions which can affect engine efficiency.

The Termodiesel Tank Heater is compatible with all tanks made of metal, aluminium and plastic between a minimum of 150 mm and a maximum of 760 mm in depth.
This innovative heater consists of a flange, to be installed in the upper part of the tank, and a heating part, with pipe that connects to the flange, for installation at the bottom of the tank.

The heating element of the Termodiesel Tank Heater, fully immersed in the diesel fuel, can heat the fuel and keep it at a temperature several degrees above zero, sufficient to avoid any blockage of the engine. A thermostat in the heating part activates the element when the temperature of the diesel drops below zero and deactivates it when it exceeds +10°C.

In the flange of the heater, which has a weatherproof plastic cover, are the power supply cables and the thermostat cables, as well as a float that draws the diesel fuel from the area heated by the heating element directly to the feed system of the engine.

The Termodiesel Tank Heater, guaranteed for 24 months, is sold in a kit with everything required for correct and quick installation on all diesel tanks.



Technical Data



- Identify the area, in the upper part of the tank, where the heater flange can be installed. Apply the sheet with the drilling template in the area identified as optimal, using adhesive tape, directing the arrow towards the area from which both the power cables and the fuel pipe will presumably arrive. This sheet shows both the positions and the diameters of the holes to be drilled on the tank.

- After having marked the centre of each hole, with a burin, drill the central passage with a Ø 90 mm milling machine and the six flange fixing holes with a Ø 3 mm drill bit (Ø 2,3 mm for plastic tanks), avoiding chips falling into the tank. To avoid contaminating the tank with the drilling shavings, you can use a magnet or a small amount of grease spread on the areas to be drilled. After drilling remove the paper template and any grease.

- Then insert the heater aluminum tube into the appropriate fitting on the upper flange and, after inserting the heater inside the tank, place the flange gasket on the tank. (To facilitate the insertion of the heating part through the hole made in the tank, just turn by 90° the plastic clip which serves to fix the draught tube to the heating part and then return to the initial orientation, after insertion). At this point, slide the aluminium tube downwards until the rubber pad, integral with the heating part, rests on the bottom of the tank.

- When both the flange gasket and the rubber pad rest respectively on the upper part of the tank and on the bottom of the same, mark the portion of aluminium tube that comes out from the top of the fitting with a marker.

- Cut the pipe, exactly to the length previously identified, possibly with a pipe cutter, to avoid any damage to the cables. After cutting, insert the yellow plastic cap to protect the cables that come out of the pipe itself.

- Using the hexagonal nut on the fitting, block the tube with the end exactly matched at the top edge of the fitting itself.
Then adjust the length of the plastic draught tube, with an excess of about 20 mm, then connecting it to the appropriate fitting on the flange. Then fix the float tube to the aluminium tube using the plastic band.

- Rest the flange again on the tank, setting it up to fix it. (Depending on the material, metal or plastic, with which the tank is built, choose the type of self-tapping screws suitable for the purpose). Tighten the screws sequentially and diametrically opposite, making the seal compress at least 3/4mm. This operation, in addition to avoiding leakages of fuel from the flange, also compresses the rubber pad on the bottom of the tank in order to block the oscillation and the vibration of the heater making it integral with the bottom of the tank itself.

- Drill the two cable glands in the kit to make them suitable for the passage of both the resistance power cables and the diesel draught tube and then insert them into the holes on the plastic cover. Power the electric resistance after having short-circuited two different coloured cables between them, and connect the diesel draught tube.
It is important to remember that the power supply must occur "subkey" in order to avoid any battery discharge. (If the search operation of the "subkey" positive and negative pole is problematic, the use of the After Key electronic power supply also produced by Protech may be useful)

- Then press in the plastic cover, fixing it through the screw supplied and the installation operation is finished.

N.B. It is essential to insert a 10 A fuse in the positive power supply pole of the resistance.
