With the convection reflow soldering system MaxiReflow, which won the "Global Technology Award 2006", SEHO has set a further milestone in soldering technology. The reflow oven is equipped with a revolutionary, thermally invisible conveyor system and a new, high-functional process gas cleaning.
Provided with the established fan technology of the product family FDS MaxiPower, the MaxiReflow yields excellent and repeatable soldering results. A very homogeneous heat distribution combined with moderate gas velocities are ensured by a large volume of ventilated process gas and especially adapted slot nozzles. Thus, a very good heat transfer coefficient is realized so that the set temperatures of the oven can remain on lower level.

- 4 Zone control
- PCB width up to 365mm
- Glass Top Design
- Built-inTemperature profile
- WComputer Control
Autotronik BS3020 is a high performance full hot air convection reflow soldering system
with computers control which can handle boards up to 365mm width with less than +/-2 centigrade degree temperatures gradient.

SEHO PowerReflow is an innovative convection reflow soldering system which is featured with low investment and operation costs, and: it is the "little sister" of SEHO MaxiReflow which won the Global Technology Award 2006.
A special innovative feature of the PowerReflow is the new transport system "LowMassConveyor". Here, the conveyor rails are carried by stainless steel ropes which are tensioned throughout the entire machine. All mechanical parts inside the process area, therefore, are reduced to a minimum as the parallelism of the conveyor exclusively is achieved with the controlled tensioning mechanism. This new and innovative concept allows very slim conveyor rails and center support which are "thermally invisible".

These high performance ovens offer industry leading production ratings and consistent high quality carbon fiber. Despatch Industries patented center to ends design yields tight temperature uniformity where you need it. Customized solutions optimize cost of ownership, power consumption and safety.
-Design forces air to move completely parallel to the flow of the fibers
-This design allows carbon fiber ovens to operate at consistently higher
temperatures without reaching uncontrolled exotherm
-The result of this technology is that manufacturers achieve 20% higher yields
with uniform density

Microwave heating and drying cabinet,
type VHM HEPHAISTOS
The newly developed microwave system, VHM HEPHAISTOS, is an internationally patented system and characterised by a very high field homogeneity.
The high field homogeneity allows for the manufacture of high-quality CFC aircraft structures, for instance.
Advantages:
Reduction of production costs due to shorter heating, process and cooling times compared to conventional methods. Use of metal parts (e.g. metal tools and charging systems) possible in the microwave field
Specific volumetric heating of products; the furnace chamber itself is not heated
Sizes from laboratory up to large scale (e.g. aircraft industry) are available (working chamber volume of the shown systems 750 and 4200 ltr); other sizes upon request
Broad spectrum of use
Technical Data
Nominal temperature: 400 °C
Heating: microwave
Control system: S!MCON/32-Net

model VA-200: Vaporizer for solid sample
Plastics, rubber, foods, pharmaceuticals, inorganic slats and other powders and solid samples.
The moisture vaporization method is used to measure samples of solids that cannot be dissolved in dehydrated solvents or electrolytes, or samples that include interfering substances. The moisture content is vaporized by heating the sample in a flow of dried nitrogen gas. It is then captured in a dehydrated solvent or electrolyte and subjected to Karl Fischer titration.
Either coulometric or volumetric titration is used.
This method is commonly used with natural substances, such as minerals and rocks, and with macromolecules such as polymers and rubber. New areas of use include electronic materials, including printed circuit boards and wafers, and printing materials, such as toners. This method is also useful for petroleum products containing additives, such as lubricants.
Convenient moisture vaporization systems are available commercially to suit various purposes. They can be connected to either volumetric or coulometric titration systems and used to measure moisture content.

860 KF Thermoprep
Simple, safe, precise
Thermal sample preparation in Karl Fischer titration.
The Karl Fischer oven method
For various reasons many substances are not suitable for a direct Karl Fischer titration:
– They release their water only slowly
– The water is released at high temperatures only
– The substances are poorly soluble in alcohols
– They undergo side reactions with KF reagents
– They contaminate the titration cell or the electrodes
By using the KF oven method the above-mentioned problems can be avoided. The substance under investigation is heated in a hermetically sealed vial in the oven. The water vapor released is transferred to the titration cell by a carrier gas. This means that no noxious solubilizers have to be used, side reactions as well as matrix effects are absent and the contamination of the titration cell is avoided.
Depending on the sample’s water content, the determination can be carried out either by coulometric or volumetric Karl Fischer titration.
Precise results
Identical analysis conditions for all samples guarantee results of the highest precision. Thanks to the heated outlet tubing the released moisture is transferred quantitatively to the titration cell.
Sample vessels of different sizes
As an option, there is the possibility to modify the oven of the 860 KF Thermoprep in such a way that you can use not only the Metrohm standard sample vials but also those used in your production plant.
