Evolution from “Test Laboratory for Heat Pumps” to “Test Center PLWP”

Test services on the highest level

In 2008, the Institute of Air Handling and Refrigeration’s test laboratory for heat pumps received the test procedure-compliant responsibility for the “determination of heat and refrigeration performance on water/water as well as brine/water heat pumps” for the first time by the German Accreditation System for Testing Ltd. (DAP) as part of the accreditation process according to DIN EN ISO/IEC 17025.

Since then, we have constantly extended and flexibilized our range of offers and tasks. Normative tests of air/water heat pumps, cryogenic condensing units, refrigerant compressors, ventilators and heat exchangers have been integrated into the service portfolio of the PLWP – besides the analysis of brine/water heat pumps.

The standard DIN EN ISO/IEC 17025 – established in 2005 and underlying the accreditation – was fundamentally revised and updated by the International Organization for Standardization (ISO) in 2017. This amendment led to the complete reorganization and modernization of the PLWP’s management system.

The evolution of our laboratory by the clearly extended service portfolio – compared to its first accreditation in 2008 – as well as by the adjustment to current accreditation requirements according to DIN EN ISO/IEC 17025:2018 shall be made clear to the professional world by the change of the laboratory’s name as well as the amplification regarding its content.

Since 1 January 2020, our laboratory has been operating under the name Test Centre PLWP at the Institute of Air Handling and Refrigeration (ILK) with the German Accreditation Body (DAkkS) registration number D-PL-11043-01.

The current certificate of the German Accreditation Body (DAkkS) proves the PLWP’s responsibility for the

  • determination of heat and refrigeration capacity (testing field 1) as well as
  • acoustic analyses (testing field 2)

in fluid energy machines and cryogenic components.
