PATENTS

Our electrical resistances, are made thanks to use of patented technologies, which give great advantages regarding the traditional techniques.

You will have the pleasure to see to improve the performances of Your systems, in which you will be able to assembly comfortably our resistances, thanks under preliminary study that we will go to realize in cooperation with Your technicians.

BENEFITS

REDUCTION OF BLOCKS
Double wire technologies permits, at same technical characteristics, to reduce the heaters dimension until the 50% in front of the same heaters made with single wire.

AINCREASE OF THE LIFE OF THE RESISTANCES
The light load on the heaters wire surface, obtained with the double wire technologies, permit a very low working temperature in front of a single wire technologies.

INCREASE OF THE EFFICIENCY OF THE SYSTEMS
Our heaters made with these technologies, grant a very good function and rendering at the machine where they are assembled.

SPIRAL WIRE

The spiral wire patents it is a technology that, starting from two couples wire (spiral or interlaced) concurs to obtain a better dissipation of the heat.

This is translated in a remarkable improvement of the rendering of the electrical resistances made with this technology.

The dimension of the heaters could be reduced of 50% of the same resistances made with traditional single wire technology.

THE ADVANTAGES:

GREATER EFFICIENCY AND EFFECTIVENESS OF THE SYSTEMS
Our heaters made with these technologies, grant a very good function and rendering at the machine where they are assembled.

REDUCTION OF DIMENSION
Double wire technologies permits, at same technical characteristics, to reduce the heaters dimension until the 50% in front of the same heaters made with single wire.

LOWER HEAT LOCALIZED ON THE WIRES
The light load on the heaters wire surface, obtained with the double wire technologies, permit a very low working temperature in front of a single wire technologies.

SOLE SHAPE

The Sole shape is the better solution for the realization of the heating resistances to use in the systems for the treatment of the air.

In effects the compact and flattened shape finds its natural positioning in the narrow spaces of such systems.

BENEFITS:

GREATER COVER OF THE ZONE OF PASSAGE OF THE AIR
Thanks to the shape increased and lengthened the sole heaters allow a complete cover of the zone of passage of the air, the special micanite supports in allow an effective support of the thread.

SMALLER NOISINESS
The eggs shape of the resistances and the precision of the implantation in the micanite supports grant the absence of vibrations also in presence of elevated speed of the air.

AIR FLOW WITHOUT FRICTIONS
The aerodynamic shape of these windings favours the passage of the air without having sensitive losses of air flow.

DIMENSIONS REDUCED WITH THE SAME CALORIC CONTRIBUTION
To power parity the dimensions of the resistances produced with these modules are reduced considerably.

LIGHTNESS
The micanite supports, calculated in thin thickness, have per result a lightness difficultly to obtain with spiral resistances constructed with steatite supports.

ALMOST NONEXISTENT THERMAL INERTIA
he knot wire construction and the double wire technology allow to obtain an almost immediate heating and cooling, reducing considerably the characteristics thermal inertia of other typology of electrical resistances.

SIZE REDUCTION

Thanks to the double wire technologies we obtain two important results:

Reduction of electric heaters dimension;
Reduction of wire surface load.

Our calculations take in evidence that, thanks to the winding of second wire on the main wire, we obtain a surface dissipating decidedly advanced regarding the same resistance realized with the single wire.

2. COMPARISON:

HEATERS LIFE

A direct consequence of the low surface loading on the wire of our electrical heaters, is that they work to “dark heat”; thanks to the double wire technologies and a correct dimensioning, our resistances work without that the wire became read because of the excessive heat.

On our heaters are always assembled safety bimetallic thermal protector, that they switch off the supply tension from the heaters, because external accidental factors to modify the conditions of job for which they have been calculated, the typical case of malfunctioning could be a reduced air flow on the heaters caused by:

  • breakdown to the fan;
  • filters too much soil.

Normally the life of the electrical resistances is tied to the operating temperature of the wire with which they are made, greater it is the temperature of job of the wire and faster it is the decay of the characteristics of the same wire.

On the table, the values of the surface loading will be able to be verified according to the speed of the air regarding the temperatures on the wire.
