On plate resistors (die-casted aluminium) for electrical heater

ON PLATE RESISTORS (die-casted aluminium)

GENERAL CHARACTERISTICS

The die-casted electric resistors (so called on plate) are designed for many industrial applications requiring thermal treatment of fluids and liquid substances, even if they are commonly used to heat water.

TECHNICAL DATA

And ‘possible to make various types of electric heaters in the die, both as standard and customer specifications, consisting of 1 element (phase type), or more elements (such as three-phase) bent on drawing to assume conformations such that fit perfectly with the inner surface of pits and grooves after the casting, or drowning in the slot of the die casting, aluminum die of various forms.
These resistors provide excellent heat exchange to the surface on which are placed in direct contact and heating elements installed in them can be as high surface loads around 23-25 W/cm2.

Assuming the most varied forms, this type of heater can be effectively installed in direct contact with the surface to be heated, both horizontally and vertically, and can also be built with high power are also suitable to operate in environments with high pressures and low volumes .

The use of quality materials in our production cycle, allows the electrical resistances of die extensive work with our production of useful service life in the medium to long term.

Given that aluminum begins to melt at low temperatures, during the operation of this resistance is, however, should be closely monitored.

USE

Cylinders of extrusion, extrusion-blow molding machines, presses for rubber
Packaging industry, machinery and equipment for hot melt adhesive
Food Industry
Machinery for window frames
Heating elements in the Flat Iron drown in aluminum castings
Electrical resistance of die-cast aluminum plate of steaming boiler with heating elements in iron, stainless steel or cast aluminum UNI-5076 with flange or threaded
Electrical resistance of die-cast aluminum plate for irons
Electrical resistance of die-cast aluminum plate for Scrubber

The electrical resistances of the die plate is aluminum: These resistors, whose elements can be made with outer sheath Iron, Stainless Steel or Incoloy800, they are often embedded with advanced technologies of aluminum die-casting. The material used (aluminum) is of the highest quality, from major suppliers.

This type of resistance is much appreciated as designs and takes many forms and is highly useful operating life. The high accuracy of execution of every detail of the mold or groove, made to customer specifications, ensures that aluminum is proven to be the best material for the construction of this type of electrical heating plate.
