Condensing boiler technology

Laboratory equipmentWe have the research and development expertise needed for continuousimprovement in today‘s world: Dedicated, intelligent engineers andtechnicians who work to further develop products, co-operating withour customers‘ development teams. The range of analyses is not limitedto harmful emissions. We also analyse and optimise EMC and noiseemissions.We support our customers in the development of applications from thevery beginning. Only when all of the necessary characteristics are presentdoes the product go into production. The tests required for this purposeinclude both inspections for complying with legal mandates and specificcustomer requirements. Numerous measuring devices are availabledirectly at the Landshut location for this purpose.For example, we also test for design effects, such as changes to thegas-air manifold, check valves or the venturi. All of these factors caninfluence the efficiency – as well as the noise level and function – of acondensing boiler and must be taken into account when matching theindividual components to each other.Gas laboratoryebm-papst Landshut has a gas laboratory with state-of-the art measuringdevices. The laboratory can also take into account country-specificdifferences, as each country has its own legislation for the compositionof the gases and the minimum and maximum supply pressure. The inletpressure in the supply line can be varied to show the effects of varioussupply networks. In addition, all testing and limit gases commonly used inEurope, America and Asia are available.We carry out exhaust gas measurements (CO 2, CO, lambda) andmeasurements with variable aerodynamic parameters (venturi pressure,modulation range, mass flow). The climate chamber also allows bothshort-term and endurance testing of external variables such as temperatureand humidity. Wind and turbulence can also be simulated.The volume of condensate produced by the condensing effect can bedetermined to measure the efficiency of the system.Air performance test rigMultiple air performance test rigs are available. They test the operatingperformance of the blowers and plot the air performance curves.Spectrum analyserThe spectrum analyser can be used to measure line-bound interference.Since our devices are used for further processing in expert industrialcompanies, we are not actually required to test their electromagneticcompatibility (EMC measurement). Nevertheless, we would like to offerthis service to our customers. This tests whether the motors fulfill therequirements of EN-55014-1, thus ensuring that there is no interferencewith devices in the environment.Climate chamberMultiple climate chambers are available in various sizes. They enableendurance tests to be carried out in a variety of ambient conditions(temperature, humidity, air pressure). This also makes it possible todetermine the service life of the devices.Noise measurement laboratoryThe noise behaviour of our blowers and systems is tested in oursoundproof noise measurement laboratory featuring state-of-the-art,high-precision sound measuring systems. By the way, these are the samereal-world conditions in which they are built into our customers‘ products.Additional equipmentOur equipment also includes a high-resolution 3D microscope and a 3Dplotter for rapid prototyping, which can be used to fabricate plastic partsfor tests on short notice.We can also carry out vibration tests to simulate mechanical loads, suchas those that occur during transport of the blowers. Equipment for testingthe type of protection is also available. They allow ambient influences tobe tested based on DIN EN 60529.8 9
