The TCW 3000 AC is now certified according to PQS (Performance, Quality and Safety) guidelines by WHO.
Most of Dometic’s Cold Chain products have been PQS approved since early 2009 when the change from PIS to the really rigorous PQS standard was effected.
Background information :
The PQS system is a guideline for manufacturers of vaccine refrigerators, vaccine freezers and waterpack freezers. The QSS group within WHO’s Department of Immunization, Vaccines and Biologicals (IVB) provides technical advice and support aimed at achieving a reliable high quality cold chain for the world’s immunization programmes and publishes performance specifications and verification protocols for cold chain and other immunization-related equipment and devices. These documents have been developed over the years in consultation with end-users, with industry and with testing laboratories and are based on a long-established and rigorous procedure for evaluating and pre-qualifying suitable equipment.
By selecting from the list of pre-qualified equipment, UN procurement agencies, governments and NGOs can be sure that they are purchasing products that are fit for purpose.
