Systema spa has got a Division for the production of gas ovens for heating, drying and dehumidification using its own exclusive technology with the gas burner BAF used with special heat exchangers in special steel: this Division is called Comex Group.
This new range of ovens offers great advantages because they can be designed on measure and on specific request of the client.
Ovens have been produced for the sectors of foundry, varnishing, food industry, wine production, dairy farming .
Our handling and varnishing systems with automatic control of the density, drying and handling of the materials have the advantage to guarantee a high quality and continuous cycle of the production.
With this new technology of ovens with gas heat exchangers there is also the advantage of a prompt investment return, because the thermal KW produced by the gas is economically more convient than the electric thermal KW, and with less problems of energy supply.
In fact, the natural gas or LPG is everywhere in quantity at a convenient price while the electric energy, in addition to be more expensive is difficult to be found in quantity for industrial productions.
Contact us to take advantage of this new technology.

CF and CDF High Temperature Infrared Furnaces for Firing & Drying
The new Despatch CF and CDF Series infrared furnaces are ideal for process applications that require rapid ramp-up and cool-down rates as well as provide consistent qualityas required in photovoltaic cell production.
Very fast ramp rates optimize contact formation on silicon wafers with shallow emitters and silicon nitride coating. Rapid heating and cooling allows firing the contact through the silicon nitrate while rapid cooling prevents damage to the junction. The rapid heating and cooling requires faster belt speeds which enhances throughput as a secondary benefit.
All models feature the most advanced ergonomic designs available, to speed maintenance and minimize downtime. With the push of a button, the entire chamber lowers for easy accessibilityno disassembly or expensive service calls for cleaning and maintenance. All electronic components are situated at eye level for easy and safe access.

The use of induction furnaces for heating material that must undergo subsequent deformation by hot pressing, is now a consolidated practice that offers great advantages with respect to traditional heating systems such as gas furnaces, resistance or radiant panels furnaces, etc.
The great advantage in the pressing sector, where the heating process for work material is required continuously, is the total absence of pre and post operation downtimes. Other advantages include rapid reaction times to any temperature variation, rigorous reproducibility of operation parameters, easy automation of the entire line, easy adaptability to the different production needs of presses, hammers, forging machines, etc.
The electrical power required by the induction system depends on production needs, on the temperature, and on the cross-section and the type of material being heated. With regards to this last aspect, we would like to emphasize that furnaces can be built for any metallic material ( ferrous or non ferrous ) and of any cross-section ( circular, squared, tubular, flat, etc. ).

Depending on the type of charge loading and workpiece geometry, there may be dead zones around the charge not seeing any flow or surfaces exposed to most of the cooling gas. To solve this problem, Ipsen has designed a rotary hearth for vertical furnaces whose speed of rotation can be adjusted in line with cooling requirements. This eliminates uneven gas flow distribution.
