customer’s requirements, including highest efficiency, zero-defect and shortest delivery time. support, innovative product solutions, reliable delivery times and unvarying high product quality. Our R&D department combines expertise within all sectors of fan technology with highly efficient simulation tools such as CFD (Computational Fluid Dynamics) for flow visualisation and FEM (Finite-Element-Method) to calculate the structure-mechanical characteristics, as well as test ducts and -chambers according to international standard ISO 5801, equipped with the latest measuring technology in order to...

System engineering and CFD analysis CAR PARK VENTILATION: THE PLANNING Natural ventilation in car parks is usually insufficient or even impossible because the building structure is mostly closed. Complex ventilation technology has therefore become industry standard, particularly due to the fact that local requirements have to be taken into account for almost every car park. Most countries have developed a national standard for car park ventilation or have adopted legislation to cover the minimum requirements. Most countries distinguish two functions for the ventilation systems. A base function...

determine if the supply or extract points, jetfans and other system components are positioned and dimensioned correctly and according to the requirements. a well-founded and comprehensive report. It shows all the positional information of the planned components for installation, in order to guarantee customers the best possible performance of the system. Taking all into account, CFD-calculation enables a founded statement about important values like air velocity and temperatures that are expected to be achieved. CFD-simulations by Pollrich DLK Fan Factories are concluded with
