Test systems - Import export

Building an effective measuring and test equipment management system can be challenging, e.g. for companies in the early stages or in need to rebuild their system from scratch. However, good planning and implementation of the set-up are crucial to ensure that measuring and testing equipment works reliably and precisely and thus the quality of your products or services is assured. We support you in implementing an effective system right from the start. We work closely with you to understand your requirements and goals and then develop a bespoke concept tailored to your specific needs. Our experienced team supports you in the selection and procurement of suitable measuring and testing equipment and takes care of the complete documentation of the entire process. We ensure that your system complies with applicable standards and that your employees can use and maintain the system effectively. That ensures reliable and accurate measurements, thus helping to improve your product quality.

With the purge air method, heat recovery for balanced air mass flows can be determined for alternating, decentralised ventilation units. The uncertainties of the direct measuring method used so far due to inhomogeneous velocity and temperature profiles at the outlet of the ventilation units are circumvented by the scavenging air method and the measuring accuracy is higher. With the optional humidity conditioning the moisture recovery can also be determined. Further thermal performance indicators are the air volume flow in alternating operation and the balance, which can also be determined with the test bench. The test stand is equipped with an auxiliary fan so that continuously operating ventilation units can also be measured with the direct measuring method.

With our HPT heat pump test bench you can simulate humidity as well as temperature. The test stand is used for functional testing of air-to-water heat pumps according to DIN EN 14511. Current test systems on the market, which are used to test e.g. air-to-water heat pumps, are climatic chambers with a cooling, heating and humidification unit fixed to the roof. The disadvantage of this concept is that it is not possible to set a homogeneous temperature and humidity distribution in the cube-shaped room. Based on test engineering concepts in the automotive industry, EP-E developed a concept in which the air flows in a closed loop (loop design). The HPT heat pump test stand is a closed-loop test stand for functional testing of air-to-water heat pumps according to DIN EN 14511. The advantageous closed-loop design uses an insulated chamber with conditioning units for temperature and humidity outside the chamber.
