HEATING SYSTEMS N - Z – G

Fluid can be heated by three different systems that also identify the type of machine:

- Range N, with electric immersed elements. The electric elements are immersed in the fluid and are set alongside the oil loop, after the electric pump in order always to obtain good heat dissipation. This avoids cracking, which would lead to the early deterioration of the oil. A resistor is made by a sealed steel jacket welded at each end to prevent fluid leakage. The internal resistor elements have an individual power of 1 kW for a total of 6 or 12 kW. The modular system can reach a power of 48 – 60 kW.

- Range Z, with electric external elements. In this version, heating elements are not in contact with the fluid but are positioned next to a IECI patented heat exchanger, with a suitable design that allows a large heat exchange surface. The real advantage is the resistor long life, a reduction in thermal cracking occurring with oil and prevention of lime scale formation on the resistors if water is used. The resistor elements have a modular power of 3 kW each, up to a maximum of 24 kW per exchanger. Use of multiple exchangers enables to reach a power of 48 kW.

- Range G, methane gas or LPG. In this case fluid heating is obtained with a special application of safe, reliable methane or LPG fuelled flame.  Carbon monoxide emission is less than 1000ppm, in compliance with current regulations. Besides the benefits of heat regulation, this (patented) modern system conveys large savings (up to 80% compared to traditional electric systems) and simplifies the plant as a whole, as large quantities of electric energy no longer need to be supplied by the grid operator (for instance fewer sub stations).

Actual combustion tests have proven that 1 m³ of methane produces a quantity of heat equal to 9.44 kW of electric energy, with large savings in energy costs (although this may change with areas and utility agreements).
