HEATING TANKS

Electric heating of tanks has become increasingly important in the special transportation of chemical products at temperatures higher than ambient, which require precise control.

SAIE has developed a fully perfected and safe system for mounting on tank semi-trailers and containers.

Components of the system:

Heating Elements

These consist of Pyrotanax cables with a Kumanal conductor, magnesium oxide insulation, and an external sheath made of AISI 304 stainless steel. They are water-resistant, flame-retardant, highly resistant to mechanical stress, flexible, and offer excellent resistance to chemical agents (such as oils, acidic solutions, alkaline solutions, etc.). Additionally, they are highly practical for installation on tanks and are finally covered with copper tape.

Control and Command Panel

Made of AISI 314 stainless steel, with protection grade IP 65, containing the following components:

• Main magnetothermal differential switch
• Manual-automatic switch
• Static temperature controller with probe
• Voltmeter for the three phases
• Indicator lights and fuses for each heating element
• CEE socket 3x32A + N + T

Generator Set

Diesel engine type, operating at 1500 rpm, coupled with an self-excited and auto-regulated alternator. It features automatic start-up controlled by the regulator located on the control and command panel. The power used depends on the requirements for the number of installed heating elements.

Connection Accessories

The connection between the above-described elements is made using insulated cables with a rubber-silicone sheath and nickel-plated copper conductors, suitable for high temperatures. All components used are guaranteed for temperatures up to 250 °C.

Thermometer

It is attached to the insulation of the tank in a position suitable for use, with the sensing element applied to the tank’s shell. It can be either a digital thermocouple type or an analog gas-filled type.
