FISCHER® OZ Ozone Generator |
|
Portable ozone generator for universal laboratory and
industrial uses, suited for oxygen and dried air as feed gas
All technical data are based on use of oxygen with operation pressure at relative 0...0.2 bar. Upon request the generators can also be used in process systems with a pressure over 0.2 bar rel. (max. 1.5 bar rel.). The gas flow is adjustable at the precision neddle valve of the sophisticated flow meter.
For reproducing the ozone production, on a 3 1/2-digit LCD display the actual ozone concentration is shown. The electrical controller allows continuous adjustment of the ozone concentration between 5 and 100%.
The ozone-generating module is made of inert material and is built together with the power supply and the instrumentation into a steel housing with an aluminium front and rear side, air ventilation cooler and carry on handle.

PC-based Control System for Automated Operation
The use of a computer-aided 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. Particular attention was paid to the following points when developing the regulating system for distillation plants:
- optimum separating performance by the individual plant thanks to easy adaptability, including changing distillation tasks
- simple operation through menu control
- withdrawal of further cuts into separate receivers
- intermittend operation for getting an optimum in distillate quality and quantity
Process sequences, regulating concepts and algorythms can be altered via the program without the need to intervene via the hardware. The system for controlling distillation and rectification plants comprises the following components:
- sensors within the plant: resistance thermometers, pressure probes, level probes etc.
- actuators in the plant: solenoid valves, heating elements, liquid and vacuum pumps, motorized regulating units etc.
- personal computer and accessories
- ILUDEST® [DC/MoS]2 unit as an interface between distillation plant and PC

Solvent Recycling Type LM |
|
The introduction of an automized distillation unit, designed by ILUDEST®, is one of the more effective means of improving efficiency. In fact, separations are sometimes so complete that it is often possible to recover solvents whose purity exceeds that of the original, newly-purchased material.
Objections to solvent recycling are usually based on concerns about the adequacy of the recovered product and the expected effort required to complete the distillation. The first concern has been addressed above and we see that, for most clinical applications, very pure materials can be recovered. The work involved in completing a distillation was considerable until the introduction in recent years of automated equipment.
An example of a state-of-the-art distillation apparatus is the ILUDEST® Model LM-6/H Computerised Recycling System.
The instrument has a capacity of 6 litres of solvent mixture with a throughput of up to 1 l/hr (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. Please enquire!
