Constant Climate

Constant Climate is our state-of-the-art cold chain product, specially designed for precision management of time and temperature sensitive pharmaceutical products. Our approved network of 109 stations are audited against and trained to deliver compliance to Good Distribution Practice (GDP), IATA TCR and product SOPs.  Our LHR hub remains the only air carrier airside facility to be GDP certified and WDA licensed by a national competent authority, the UK’s Medicines & Healthcare Products Regulatory Agency (MHRA). Our DUB hub is certified under the Irish Exporters Association (IEA) GDP Passport programme, and our MAD hub is commencing a GDP certification programme in 2018.
