About the ATP laboratory

COCH refrigeration laboratory

The COCH Laboratory operates in accordance with the requirements of PN-EN ISO/IEC 17025.

The Laboratory of Refrigeration Equipment of the Central Refrigeration Center “COCH” in Cracow Sp. z o.o. performs tests of air-conditioning refrigeration equipment including heat pumps and liquid chillers (chillers). It conducts its activities in accordance with the requirements of PN-EN ISO/IEC 17025, and the tests performed are covered by the accreditation of the Polish system of testing laboratories (accreditation of the Polish Center for Accreditation No. AB 308) and the license to use the international mark ILAC MRA, about mutual recognition of test reports issued by accredited laboratories around the world.

The laboratory has specialized test stands, including several test chambers that provide testing capabilities for equipment with a wide range of performance.
