The AQUACHEM LCM 320 (pocket press membrane) is ideal for mobile deployment on site on a suitable trolley and can be operated with up to 15 bar loading and 15 bar membrane squeezing. This machine can also be used as a testing filter press in the case in order to decide on the right fabric or to check the filterability of the suspension. Fully equipped, this compact press can manually implement functions that our fully automatic machines can do. The AQUACHEM LC 320 (pocket press chamber) is identical in design to the LCM 320 and differs only in its function as a chamber filter press (without membrane). The LC 470 is the more affordable, low-cost version of the EC-series. Main feature is the restriction of the feeding pressure to 7 bar. All other features are the same as the EC-series. This series is built in a compact design with a feeding pump and discharge manifold.

The AF filter presses from AQUACHEM are a further development of conventional chamber filter presses, which have been tried and tested in the industry for over a century. However, due to the degree of automation required and the increase in efficiency necessary nowadays, the technology we have had up until now is often no longer up to date. The design of the AF filter presses is based on the optimum interplay of the ?? individual assemblies of the filter press to ensure reliable, efficient and permanent operation without personnel being present. The automated flexibility of the product enables autonomous adjustment to changing conditions, such as concentration or even specific filter properties. We guarantee these properties and also availability. This is only possible because AQUACHEM and the AF-series possess the knowledge, an intelligent control system and the technology for maximum flexibility. Yes, this is a product with unique selling points – test it out yourself.

High-precision pressure sensors from the 8201 series provide exact measurements while exhibiting very little sensitivity to mechanical stresses. Their application therefore goes well beyond research and development laboratories. They are also outstandingly suited to industrial use in quality assurance or for measurement and control tasks in production. Their robust mechanical and electrical construction guarantees good long-term stability and high reliability, while being resistant to aggressive media – which can be measured in liquid or gaseous states. The structure of the sensors includes no mechanical moving parts, which is why they show so little sensitivity to impact and vibration. The pressure sensors can be configured with options to suit the user. Standard types are available ex-stock, and customized customer versions can also be provided. Aeras of application are: —Research and developmemt —Test rigs —Mechanical engineering —Plant control and monitoring

Model number 8201 precision pressure sensors are robust, economical, and are available in standard measuring ranges. Their good technical specification and high reliability make them optimum for measuring pressure in all fields of machine construction, process technology, as well as in measurement and control technology. The pressure transducers are easy to handle and immune to shock loads and vibrations as they are designed without moving parts. All pressure transducers without an internal amplifier have a standardized output signal of 1.0 mV/V. This enables the user to change a transducer in a measuring chain as liked without following readjustment of the electronic. Customized designs are available on request. Aeras of application are: —Hydraulic or pneumatic machines —Mechanical engineering —Plant control and monitoring The measuring element of the precision pressure transducer consists of a diaphragm.

In addition to filtration, compressed-air drying contributes significantly to an increase in process reliability. Humidity in compressed-air systems causes corrosion, and promotes the growth of micro-organisms. In individual cases, condensate emerges at the point of use - an ongoing danger for the operational flow, for example because of failing pneumatic controls, increased wear and tear or because of other disturbances in the production process. With considerably enhanced process reliability, the DRYPOINT dryer technology offers decisive advantages for every field of application. The BEKO TECHNOLOGIES portfolio comprises application-optimised refrigeration, adsorption and membrane dryers for volumes up to 1,500 m³/h. This range of dryers is completed by heat-regenerated EVERDRY adsorption dryers which are designed for large volume flows up to 20,000 m³/h.
