Refrigerated van is a general term for any vehicle with an active cooling unit – it’s not the type that applies, but the category. There are two types of chiller vans within that category, with the chiller van being insulated and powered to operate at 2°C to 8°C, and the freezer van with a heavier-duty compressor and thicker insulation for operation at -18°C or below. For temperature-sensitive medicines and pharmaceutical products, Pharma Cold Transport requires the vehicle and temperature range to match the cargo’s specific requirements. These are not interchangeable, and this is the biggest mistake we get from first time renters searching for a refrigerated van.
