Based on our network of ceramics and electronics suppliers, and with a modern production line with a high degree of automation, our site in Niederndorf produces cost-efficient, large-scale production models as well as exclusive models with sophisticated original materials.

With the new ALO manual welding laser, you can either work manually or with an axis of rotation for circular welding. The working chamber is easily accessible via leather curtains, but the welding itself still takes place in the shielded laser safety area. The spacious working chamber can be loaded quickly through various openings, without opening doors: a large opening at the front ensures easy access to the welding chamber. The slots on the side enable the operator to position longer components in the machining area and to weld them in a laser-safe manner. Another passage on the bottom of the working chamber allows loading from below. The laser safe leather curtain offers certified laser protection so that the laser device can be placed in any work environment. The armrest is extremely comfortable - ensuring relaxed work. A lot of attention was also paid to good ergonomics. A high-quality extraction system with filter is integrated as standard.

The use of a computeraided system is well suited for the control and regulation of distillation and rectification plants the wide range of measurement and regulating tasks, the need for flexibility, ease of operation and a display of the operating parameters make the use of a computer with the relevant software and peripherals appear the ideal solution.

The instrument has a capacity of 6 litres of solvent mixture with a throughput of up to 1 l / hr (e.g. when recovering Xylene). A microcomputer controller holds up to 100 programs as well as monitoring the distillation process for normal and safe operation. Variable reflux ratios and equilibrium times are possible so that the operator has maximum flexibility to design a program for optimal efficiency. Other capacities are available upon request.

Especially the theoretically additional evaluation of the temperature and pressure dependence of phase equilibrium is insufficient very often in daily practice, thus the experimental determination of VLEdata is increasingly requested in the overpressure range, too. ILUDEST®/ iFischer® modified the VLEequipment, since decades sold under the worldknown FISCHER® brand, suitable for the overpressure range up to 50 bar. The VLEequipment is designed for a charge of 50 ml (dynamic mode) and can be operated under vacuum (1...1,013 mbar), atmcondition and overpressure (1...50 bar) as well as temperature up to 250°C. An extended operating range up to 100 bar is possible.

Scientists and chemical engineers still measure phase equilibria despite the significant improvement in theoretical evaluations. Therefore, our phase equilibrium apparatus is part of the standard equipment in chemical engineering laboratories. The vapourliquid equilibrium of binary and multicomponent mixtures constitute an essential basis for the determination of the theoretical plates necessary for the evaluation of separation processes. Although VLEdata are known from literature, there is still an increasing tendency towards redetermining equilibrium data by experiments, because the thermodynamic parameters like pressure, temperature and concentrations are different or inadequate. For designing e.g. extractive distillation processes the evaluation of vapourliquidliquid phase equilibria (VLLEdata) are required. The practical measurement and determination of these data proves difficult with the standardised VLEunits because of the phase formation of the liquids.

Because of the thermal sensitiveness of products, this separation method is applicable. The medium which is to be distilled is exposed only for a very short time to the heating substances because the film, which is created by the wiper, can evaporate very quickly. The residence time of medium on the heating surface is a matter of seconds, thus essentially less than in a reboiler flask, circulating evaporator etc. Evaporators in borosilicate glass 3.3 are available with heat exchange areas 0.02…0.8 m². Alternative design versions in stainless steel for higher throughputs are available upon request. Please equire.

The unit for the liquid/liquid extraction operates in a countercurrent flow and is designed as a pulsed column with sieve trays and packing material alternatively. The working principle of this unit is based on the fact, that the two liquid phases are pressed through the holes of each sieve tray or through the packing respectively, forced by the used pulsation, thus one phase will be dispersed into the other. The large contact surface which will be formed by this specific design, makes the product exchange between the two phases highly efficient. During the return travel of the pulsator, the drops previously dispersed are agglomerating into a homogeneous phase. The light phase will be fed into the system at the lower end of the column, while the heavy phase is entering the tower at the upper end. Due to the gravitation, supported by the said pulsation, both phases are passing the column in countercurrent way and are withdrawn at the opposite ends.

For liquidliquidextraction according to the MixerSettlerprinciple, design acc. to Dr. E. Müller (Lurgi). With screw stirrer for intensive mixing of the phases, especially suited for metallic salt extraction. Pumping capacity and residence times are changed by adjusting the stirrer speed. An additional advantage of the unit is the application for extractions during which reactions of considerable density changes occur. Typical applications for this universal apparatus are metal salt extractions mixtures with low surface tension if the dispersed phase coalesces with difficulty if variation in residence time of the phases occur in the extraction stages if reactions are expected during the extraction process if considerable changes in density are expected as a result of extraction

In petrochemical and chemical process engineering, screw pumps, acting as displacement pumps, offer hydraulic characteristics which make them indispensable for the entire viscosity range. In chemical applications in particular, the high suction force and the gentle handling of the fluids to be pumped are the outstanding features of this type of pump. In general, all of our pumps can be used in this field, but the most common one is the two-rotor pump. Leistritz screw pumps are used to pump clean or slightly abrasive, low and high viscosity fluids with lubricity from poor to good, such as: additives, bitumen, resins, crude oil, greases, benzenes, adhesives, silicates, isocyanates, tar, polyols, asphalt, paints/varnishes, paraffin, polymers, and various other chemical products.
