The Hiresta – UX measuring device is used to measure semiconductors or non – conductors (insulators). Measuring range of 10^3 – 10^14 Ω . The Hiresta UX is specialised in measuring the resistance, the surface and volume resistivity of various substances and materials of all shapes and sizes in the high-resistance measuring range. For measurements related to the ASTM D257 / ISO 2951 / JIS K 6911 standard of: antistatic materials flooring materials paper, packaging materials paints, pastes, paints fibers, clothes, fabrics adhesives, greases glass, concrete, ceramics plastics, film materials, foils etc. Up to 2000 measurement results can be exported to USB memory stick The conductivity meter impresses with its compact design, a color 7.5 “TFT touch display and user-friendly menu navigation.

Our all-ceramic bearings are characterised by their high corrosion resistance to seawater and various chemicals. They are therefore used, for example, in the chemical industry, in the food and beverage industry, in shipping and in chlorine systems. We can manufacture our full ceramic ball bearings with rings and balls made of zirconium oxide (ZrO2) or silicon nitride (Si3N4), depending on the application. They are available with full balls or with cages made of PEEK or PTFE. The runout accuracies common with precision steel bearings cannot be achieved with all-ceramic bearings, so speed values have to be reduced. Ceramic materials are harder than steel, but also more brittle. Silicon nitride in particular has a low elongation at break and tends to break under tensile stress without prior plastic deformation. We take this into account when selecting the optimum bearing solution for your specific requirements.

The regenerative thermal oxidizer from Venjakob Umwelttechnik with its low consumption of primary energy is particulary well suited to the removal of low to medium concentrations of solvend based pollutants (VOC). This machine is characterized by: The regenerative thermal oxidizer (RTO for short) embodies the state of the art technology for cleaning organic pollutants from exhaust gases (including VOCs). The systems ordinarily feature three alternately supplied heat exchanger chambers equipped with ceramic honeycombs. This material is suitable for absorbing, storing, and transferring very high amounts of heat. This allows a heat exchanger efficiency of over 95% to be achieved, so that the process temperature above 800 °C, which is required for the pollutant conversion, can be reached with a minimum of additional energy. Consequently, depending on the combustion heat of the pollutants to be cleaned, autothermal operation can be accomplished for most applications without the need for additional fuel. With careful planning, the excess heat of combustion can be effectively utilized so that the overall system can be viewed as an energy source rather than as an energy consumer. We can offer a variety of special solutions depending on the application:
