We are proud to announce that our test lab has been assessed and found to comply with the applicable requirements of ISO/IEC 17025 in accordance with UL’s Data Acceptance Program (DAP) and has been qualified as a DAP participant in the Client Test Data Program (CTDP) for the testing and certification of special purpose air conditioning systems.

CTDP certification is awarded to companies that demonstrate the highest levels of quality management, laboratory testing capability, technical expertise and knowledge of industry standards. UL reassesses CTDP certification annually.

The CTDP certificate enables Pfannenberg to perform testing in its own laboratory, equivalent to the testing that UL performs. UL thoroughly reviews all data submitted by the Pfannenberg lab before issuing the UL Mark certification. CTDP certification significantly shortens the turnaround time for UL Mark certification, improving the speed to market for Pfannenberg new products and enhancements.

The Pfannenberg lab performs a wide range of tests critical to analyzing the performance and safety of air conditioning systems, including Computational Fluid Dynamics Analysis (CFD), as well as environmental simulations, a climatic chamber, and IP protection class tests. The lab also performs transport and vibration tests and EMC / noise emission tests.
