Cold Chain Equipments

We have high quality cold chain equipments to offer, many of our products are imported by several countries. Cold Chain Equipments are the lifeline for heat-sensitive vaccines and is essential for transportation of these vaccines from the place of manufacturing to the place of field storage and final carriage to the place of immunization. Thus, CFC-free cold chain equipment ensures a pre-determined safe temperature range (-3 to + 10 C) for a particular period known as cold life of the product. The cold life period varies according to the product classifications made by WHO i.e for large equipment like cold boxes, the cold life is high whereas for small equipment like vaccine carriers box the cold life requirement is less. WHO has formulated rigorous test procedures for maintenance of cold life and for overall strength of the equipment and its fittings, to withstand various rough field usage conditions. The equipment has to undergo tests like drop test covering 26 drops (all sides, corners and faces) of the box to ensure compliance with rigid WHO standards and requirements. WHO approval is accorded only after successful clearance of all tests by the test laboratories.
