Air-water / air-air heat exchanger as smooth tube heat exchanger up to 1,000 ° C Smooth tube heat exchanger as an air / water heat exchanger In the case of air-water heat exchangers (also called gas-water heat exchangers), a temperature exchange takes place between a gas (usually air) and a liquid. As a rule, the liquid medium flows inside the pipes, while the gaseous medium flows around the pipes outside the pipes. Smooth tube heat exchangers can cover various areas of application: heating, cooling and condensing as well as heat recovery. Smooth tube heat exchanger as air-to-air heat exchanger Smooth tube heat exchangers are also often used as air-to-air heat exchangers. In this application, a gas (e.g. exhaust air or exhaust gases) flows inside the pipes and a gas (e.g. fresh air) outside the pipes around the pipes.

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.

With high-quality filter tubes and PTFE diaphragms. Paint dust filters Wet painting also results in overspray. Overspray is the solid portion of the paint that is not taken up by the workpiece. According to the purpose of use, the overspray is moist and sticky immediately after release. It is captured by the exhaust air stream in the spray booth and fed to a filter. This can be, for example, a baffle plate filter, paper filter, fleece filter, glass fibre filter or also combinations of these. The adhesive effect causes the paint particles to adhere to the contact surfaces of the respective filter medium, as a result of which a good degree of separation is achieved. However, all these filters are storage filters, i.e. the filters clog up more and more during operation and cannot be regenerated. A filter exchange becomes necessary if the exhaust air rate of the spray booth falls below the minimum. This can be very time-consuming under certain circumstances and the work process must be interrupted in order to do it. To make things worse, not only must the filtered and bound paint residues be disposed of, but also the actual filter materials. Such tooling times are not justifiable for automatic, continuous or multi-layer painting processes. Continuous procedures such as automatically cleaned filters are likewise required for this. The humidity and the adhesiveness of the particles to be filtered are thereby the problem. In order to solve this problem, the paint particles should be relieved of their adhesive capability as far as possible whilst still inside the paint booth. Our patented ‘RTS-Rotation’ system is outstandingly well suited for this. The system is comprised of slowly rotating brush rollers, which take up the adhesive paint particles on the surface of the bristles and allow them to dry there. The bristles are automatically regenerated at pre-specified time intervals by combing devices that swing in at the rear of the brush rollers. The dislodged paint residues can then be removed and disposed of either manually during work breaks or automatically during operation. The degree of separation of this system is, however, insufficient to satisfy the environmental protection requirements concerning residual dust content in the exhaust air. A further filter stage is necessary for that. It must be assumed that the paint particles arriving here are to a certain extent still damp and sticky. For this we use special paint dust filters with high-quality filter tubes with PTFE diaphragms. If necessary, precoating agents (auxiliary dust) are used in order to neutralise the adhesive capability of the particles and to keep the dust layer on the filter elements permeable to air. The precoating agent is injected into the raw air pipe by means of special dosing units. The filter tubes are cleaned by means of compressed air impulse cleaning. The use of this technology requires special know-how. We have had the appropriate experience for almost ten years. The implemented plants have capacities ranging from 5,000 to 90,000 m³ /h. Because of the large number of different paint systems, individual experiments are usually necessary in our pilot plant in order to find the correct solution for the individual case.
