Waterproof enclosures with protection grades IP67 or IP68 for outdoor use are not automatically sealed against vapour and humid air. To avoid negative pressure, high humidity and condensation inside the enclosure a continuous Ventilation and pressure equilibrium is necessary. This function can be achieved by using a venting element made by Jacob. Features: - Continuous ventilation and adaptaion on the inner pressure - Hydrophobic and oleophobic PES- membrane - Body from stainless steel 1.4305 - Theoretical air flow through usable surface up to 75 l/h at Delta-p = 0,07 bar - Water entry pressure >= 0,83 bar (dynamic WEP, 30 seconds) - Temperature range -40°C / +100°C - Protection grade IP66 / IP68 - 0,6 bar (60 min.) / IP69

FLL-certified roof protection layer made of soft PVC for installation on non root-proof roofs, for forming a watertight and root-proof basin on green roofs with water accumulation and as water-proof and root-proof lining in planters.

LIPP® offers a wide range of Roofs and Covers for covering liquid, solid or gaseous media. They can be tailored and adjusted to each application. They include both roofs developed by LIPP® and also solutions designed by our partners. There are also simple foil roofs to choose from for gas storage facilities as well as singleskin, doubleskin or double diaphragm roofs. The LIPP® stainless steel diaphragm roof also offers a particularly highquality solution for the storage of volatile or explosive substances while the versatile LIPP® segment roof completes the range of covers.

Optigrun root protection membranes are used on non-root-resistant roof waterproofing under extensive and intensive roof greenings.

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

With its rugged housing and a stainless steel sensor element, the transducer is particularly robust and ideally suited to the harshest environments. This also means that the sensor can be installed anywhere with no effect on the measurement signal. The built-in instrumentation amplifier converts the sensor signals into noise-immune voltage signals or current signals that can be transmitted over relatively long distances. For high viscose materials, a front-level membrane M12 x 1 is available, and with this disruptive dead volumes can be expelled. The sensor has a small protected hole on the rear to allow measurement of atmospheric pressure (measurement type relative). For the absolute measurement option, the applied pressure is measured with respect to an enclosed vacuum. As an electrical connection, a DIN 43650A valve connector or an M12 x 1, 4-pin connection is available.

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.

Separation of dissolved gases with membrane degasification Gaseous components can be removed by conventional technologies, like e.g. percolators columns (for example CO2-percolators). Alternatively, gaseous components in water can be removed with very high retention rates by membrane degasification, which is working with hydrophobic membranes and a partial pressure drop. The advantages of the membrane degasification are low operation costs as well a s compact design.

Membrane filter presses have a great influence on the dryness of the solid by using membrane technology in the filter plates. Compared to conventional filtration processes, it achieves the lowest residual moisture values in the filter cake. This makes the membrane filter press a powerful and the most widely used system. IF TIME AND DEGREE OF DEWATERING ARE CRUCIAL Depending on the degree of dewatering, different dry matter contents ( – percentage by weight of dry material in filter cake) can be achieved in the filter cake by squeezing with membrane plates. The range of achievable dry matter contents extends from 30 to over 80 percent. Membrane filter presses not only offer the advantage of an extremely high degree of dewatering; they also reduce the filtration cycle time by more than 50 percent on average, depending on the suspension. This results in faster cycle and turnaround times, which lead to an increase in productivity.

A third category of membranes is used for degassing liquids. When applying a vacuum to one side of the membrane, the liquid itself is not permeable and there is no loss. One typical application is removing dissolved oxygen from brewing water in order to avoid any oxidation processes.
