Protectiv gas generators

Are you looking for protective gas generators to implement in your industrial plant?

Sabe Forni has created a selection of protective gas generators, which meet the safety needs of the industrial sector and, in particular, of companies that perform heat treatments of metals.

Industrial furnaces for heat treatment of metals require, in most cases, the use of protective atmospheres, generated by a gas generator such as, for example, nitrogen. The composition of the gases varies according to the materials treated, depending on their affinity with oxygen.

Within the Sabe Forni range, you will find different types of gas generators, including:

Endogas generators

The endothermic gas generator is preferably used in the processing of carbon steels.

To ensure that the production of endogas takes place entirely, it is necessary to have a certain level of heat, which generates the endothermic reaction. The generated gas is normally reducing and cementing ferrous materials.

This endogas production takes place thanks to the passage of a air-methane mixture through reaction towers at 900 ° -1000 ° C filled with nickel catalyst. With the addition of small quantities of hydrocarbons, endogas becomes hyper-fuel and is commonly used in furnaces of different sizes and characteristics.

Exogas generators

For processing wires, strips, sheets, etc. with a low carbon content, Exogas is used, obtained through the partial or total combustion of gaseous hydrocarbons and much more competitive from an economic point of view. This combustion process, in fact, which takes place within special reaction towers, produces a protective atmosphere.

Furthermore, this type of gas, in addition to constituting a mixture suitable for the blank solubilization of low carbon content wires, strips, sheets, represents a valid solution for the controlled oxidation of magnetic laminations, when the process is carried out without the condensation of the outgoing water. If, on the other hand, the combustion occurs almost completely, this gas finds application in the bright solubilization of copper.

Ammonia dissociators

Dissociated ammonia has applications similar to those of pure hydrogen. However, compared to it, it is less expensive; therefore, it is used for the “white” solubilization of low carbon steels, including stainless steels. It cannot be used in those cases where the nitriding of stainless steels containing titanium and molybdenum can occur.

These applications are possible as the anhydrous ammonia at a temperature of 900 ° thanks to the passage on a catalyst bed, where it dissociates into its gaseous components consisting of 75% H2 and 25% N2.

Dissociated ammonia dryers

The dryers allow to obtain the almost complete absence of humidity in hydrogen-rich atmospheres, using molecular sieves positioned in regenerable absorption columns. The two towers can be heated electrically and independently by resistors and work alternately, cold for drying and hot for the regeneration of the dehydrating substance.
