Test stands - Import export

HELLER uniPro 90 Machine tools manufactured by HELLER are used around the world in the machining sector. Many of the older processing centres are using the "uniPro 90" controller for which we offer completely reconditioning repairs across the entire product range. In addition we are selling new, replacement and exchange parts. We are also able to test these HELLER controllers on our internally developed test stand and guarantee full functionality following repair. By using original components for every repair, we can also offer you an 24month warranty* on the complete assembly. The product portfolio for the HELLER uniPro 90 product range currently consists of inputs and outputs, plugin cards from the ACPU90 range, control panels, system cards and power modules.

We think the finer details are important, so we have developed a design that we think, not only stands out against the competition, it’ll also stand the test of time. Our CAD team have developed a kitchen cabinet design that runs through our precision CNC to give your birch plywood kitchen units a truly unique feel. Whether you want overlay or inset doors, we’re sure you’ll be blown away with the end result.

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.

We offer you a comprehensive service portfolio around your measurement technology: whether we support you in the complete project or only in sub-areas, is entirely up to you. Starting with the project planning and construction, over the commissioning and support with the CE certification up to the maintenance of your test stand - our offer extends.

Apparatus for pressurizing test pieces We offer burst test benches to test load-bearing elements under pressure for their resilience. The components to be tested are put under pressure until they burst. Depending on the requirements (e.g. depending on the medium, pressure range, static or pulsating tests) we build your customized test stand.

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.
