Prüflabor Wärmepumpen at ILK Dresden


Dr.-Ing. Matthias Böhm


Test Fluid-Energy Machines and Components

The laboratory for testing heat pumps at ILK Dresden - Prueflabor Waermepumpen - PLWP has conducted the reaccreditation in 09/2016. Since september 2016 we are reaccredited until 2022. The testing fields "Determination of the heating and cooling capacity of fluid energy machines and refrigeration components" as well as acoustic determinations on fluid energy machines and refrigeration components were verified.

Our two testing fields include especially measurements of heat pumps, refrigerant compressors, condensing units and heat exchangers (test standards EN 14511, EN 14825, EN 16147; EN 13771-1, EN 13771-2; EN 327, EN 328; DIN EN ISO 3741; DIN EN ISO 9614 and DIN EN 12102). 

In the result a test report is created (DAkkS checking-seal), that is internationally acknowledged within the framework of the ILAC-agreement.
