Dr. Paul Lohmann® offers Potassium Acetate as powder, fine granules and granules in food/pharma/chem. pure grade. For pharmaceutical applications, it is used for parenteral nutrition. For biopharmaceutical applications, it is used as pH buffer in purification processes. For food applications, it is used as acid regulator. For industrial applications, it is used as an isomerization catalyst for the production of rigid polyurethane foams. Specific fire extinguishing agents and the modification of catalysts are further areas of application. CAS 127-08-2 EINECS 204-822-2 Dr. Paul Lohmann® carries out product and application development in close cooperation with customers. This includes the adaptation of chemical and physical parameters such as bulk density, wettability, particle size, purity or pH-value.

The term inline filter refers to an expandable, bolted, modular system. Depending on requirements, appropriate filter and air injection sections are connected together in series. The capacity range extends from approx. 10,000–300,000 m³/h. RS / RX filter The RS / RX series are a proven, expandable, modular system with low-pressure purge-air cleaning. Depending on requirements, appropriate filter and air injection sections are connected together in series. The capacity range extends from approx. 20,000–300,000 m³/h. RS / RX filters are suitable only for vacuum and positive pressure operation. The housing parts are usually made of 2 mm thick galvanised sheet steel. A thicker material in a painted execution as well as in stainless steel is also optionally available. The RS / RX series is 2.85 m wide. Filter hose lengths of 3 m (standard) and 4 m are available for this. The RSEC series has been designed for smaller air quantities and for above-roof installation. This series has a housing width of 2.4 m and 2 m-long filter hoses. The filter hoses are manufactured from polyester needle felt; the filtering direction is from the outside inwards. Filter cartridges and filter tubes are alternatively possible. The filter hoses are cleaned off using the material-preserving low-pressure purge-air system. The purging trolley inside the clean air compartment drives over the hose openings either continuously or controlled by pressure. In the direction of movement the first filter hose row is neutralised, while the second row is flushed from the clean air side. The third row is likewise neutralised. This results in a draught delay, which is necessary in order to allow the dislodged dust to fall into the discharge. The dust is discharged by a tried-and-tested drag conveyor with a downstream cellular wheel sluice. The return air pipes are provided with fire protection flaps and switching devices for exhaust air operation. The filter housing has been tested for resistance to pressure surges. Standard safety devices include likewise tested explosion pressure relief devices, fire extinguishing systems, mechanical and thermal monitoring systems as well as pressure-surge-resistant and flameproof cellular wheel sluices. The transport fan is arranged on the clean air side and is not exposed to swarf and dust. Hence, the conditions of a dust explosion zone do not prevail in the transport fan. RSV/RXV filter This series essentially differs from the RS/RX series in that its fans are arranged on the clean air side. RSV/RXV filters are suitable only for vacuum pressure operation. The capacity range extends from approx. 20,000 - 300,000 m³/h. The filter hoses are likewise cleaned off using the material-preserving low-pressure purge-air system.

The mini MACE is suited for, for example, the cutting and opening of pipe bombs, hand grenades or potentially hazardous objects such as unconventional explosive devices in the form of fire extinguishers and cases. mini MACE combines an abrasive mixing unit and a high-pressure pump in a single casing. The working pressure of the unit, which is driven by an internal combustion engine, is 6525 PSI (450 bar). The mini MACE was developed as a mobile penetration and cutting tool. An autarkic complete system equipped with internal combustion engine, abrasive mixing unit (AMU) and high pressure pump for accessing and deactivating IEDD (Improvised Explosive Device Disposal). It could be also used in the industrial sector for e.g. opening tanks.

The FPDR type of conduit made of specially modified Polyamide 12 provides self-extinguishing fire characteristics and excellent fatigue strength against continuous dynamic flexing movements. Especially suitable for heavy duty robotic applications. These conduits also offers good mechanical strength such as chafing resistance as well as very high chemical resistance. Therefore this product perfectly matches for most demanding application requirements. Application: Robotics

The SANHA®-Therm installation system consists of tried and trusted SANHA®-Therm press fittings from carbon steel (c-steel) with a black sealing ring from EPDM (ethylene propylene dien rubber monomere) and SANHA®-Therm carbon steel pipes according to EN 10305-3. The carefully manufactured installation systen and its components offer an economically attractive solution for closed heating installations. At the same time, SANHA®-Therm ist especially well suited for pressurised air and fire extinguishing systems according to EN 10346 (DZ version). The variant "Contiflo" also offers galvanized system pipes which are characterized by being easy to bend. Our C-steel system is furthermore available as a LABS*-free version (series 27000).

We have developed an extensive range of high-quality extinguishing agents in the course of decades of research and practical experience. RÜHL fire extinguishing agents are available for universal use (in several fire classes) or for specific applications (in only one fire class). Our products are approved according to current standards. ABC powders can also be used against metal fires as well as in the presence of voltage. Please observe the corresponding national regulations.

GFK Systems PUR Systems Fire Extinguishing Agents Cleaning + Disinfection Infothek About us Contact Products Polyester Foam Resins Polyester Resins Applications Service Quality Newsletter Contact, Glass Fibre Reinforced Plastics Polyester Foam Resins Compared to conventional matrix systems for fibre-reinforced products, UP foam resins offer material and weight reductions of up to 30 % thanks to their micro-cellular foam structure. In simple sealed moulds, glass fibre reinforced plastic components that are smooth on both sides are produced cost-effectively under a vacuum in comparatively short cycle times. The production of sandwich components resistant to bending, with a foam core, and the direct integration of metal reinforcements and threaded elements – for example for large vehicle components – has also proven itself. Typical properties Dense matrix / composite of approximately 0.6–0.7 g/cm³ / 0.7–1.2 g/cm³ Fibre content 20-50% of total weight Moulded part mass per unit area of 3000–5000 g/m² Flexural modulus of elasticity 3000–8000 MPa Bending resistance of 35–185 MPa Impact resistance of 35–65 KJ/m² (with 20–35% glass content) Reinforcing materials: Continuous glass fibre mats Composite glass fibre and fleece mats Natural fibre mats Special formulations and versions Systems with long processing times for very large components Foam resin formulations with elevated dimensional stability under heat Systems for fibre-reinforced components with a high level of characteristics Coordination with gel coat / top coat for surface refinement Flame protection formulations Electrical industry: UL 94 V0 Rail vehicle construction: DIN 5510 (S4, SR1, ST2)
