Moving medicines and vaccines in Dubai: the 2 to 8 degree run

Refrigerated medicines sit in a band of 2 to 8 °C. That is not a maximum with room underneath it. It is a window six degrees wide, and a driver who pushes the dial down to be safe is as likely to write off the load as one who leaves the doors open. Vaccines, insulin and a long list of biological products are freeze-sensitive: once they have been below zero, the damage is done and it is not visible through the packaging.

On a medicine round, the question at handover is not “is it cold?” but “has it stayed between two and eight the whole way?” The answer has to come from a record, not from a hand on a carton.

There are two other bands worth naming, because they get confused with this one. Frozen pharmaceutical products sit at −18 °C or below, which is a different setting and a different run. And a great many medicines are labelled for controlled room temperature, usually 15 to 25 °C, which sounds like it needs no vehicle at all until a Dubai afternoon puts a parked load well past thirty. Our refrigerated bodies will run anywhere from −18 °C up to +5 °C, but only at one setting at a time, so a 15 to 25 °C load is a separate conversation rather than a chiller booking.

The 1-Ton Chiller Van does most of this work in Dubai, and the reason is access rather than volume. A pharmacy round is fifteen or twenty short stops in Karama, Deira, Al Barsha and Jumeirah, where the van that pulls up at the shop front wins over anything parked fifty metres down the road. It is also the only refrigerated vehicle we run that an ordinary car licence covers, which matters when the person delivering is a pharmacy assistant rather than a professional driver.

A 3-Ton Chiller Van is the step up for a wholesaler replenishing its own branches: a 4.2 m insulated body, loaded with roll cages or stacked totes rather than pallets. It needs a heavy licence, or one of our drivers at AED 250 for a nine-hour day. Above that, movements between an importer at Jebel Ali and a distributor’s cold store are pallet work and belong on a refrigerated truck; the bodies and pallet counts are set out in the chiller truck sizes guide.

One sizing note that catches people out: the constraint on a medicine round is almost never weight. Twenty totes of boxed product weigh very little against any of these payloads. What runs out is stable floor space where cartons will not slide, and the number of door openings the route can absorb.

The unit display is a live reading, not a record. It tells the driver what is happening now and keeps nothing you can show afterwards. If your procedures require evidence for each delivery, that evidence comes from a data logger travelling with the goods, and the logger belongs to the consignment rather than to the vehicle. Put it with the product, not on the bulkhead, and not in the cab.

Loggers come in two useful shapes for this work. A single-use logger goes in the box, is read at the destination and gives you a straight answer for that shipment. A reusable logger is downloaded at the end of the round and covers the whole run, which is cheaper across a daily route but only proves the vehicle, not each carton. Whichever you use, decide in advance who reads it, where the file is stored and who is told when it shows a problem.

Ask us for what we hold rather than for what we cannot produce. We can confirm the vehicle, the refrigeration unit, that it went out pre-cooled, and the collection and return times. Tell us at booking if the run has to be documented and who reads the data, and we will say plainly what we can supply and what has to travel with your goods.

The same applies to the delivery note. Batch numbers, quantities and the receiving pharmacist’s signature belong at the door, not in the van afterwards; a note written from memory at the end of a round is the one that fails an inspection.

Every door opening on a summer round is a heat load the unit has to remove before the next one. On a pharmacy route with twenty stops, those openings add up faster than the driving does, and the body arrives at the last drop with less margin than it had at the first. The fix is not a colder set point. It is fewer and shorter openings: everything for one stop picked before the door opens, one person at the doors, and the load organised in delivery order so nothing is hunted for with the doors wide.

Route order carries more of the answer than people expect. Put the most heat-sensitive consignments first, keep the long motorway legs for when the body has recovered, and build the round so the vehicle is not standing in direct sun with the engine off. A van parked for twenty minutes outside a clinic in Al Quoz gains heat through the roof whatever the unit is doing.

Insulated boxes with conditioned gel packs earn their place on the last leg, between the van and the counter. That walk across a car park, through a mall service corridor and up to a pharmacy is where a load that has been perfectly handled for two hours can be spoiled in four minutes. Condition the packs properly and keep them off direct contact with the product, or you have simply moved the freezing risk from the van to the box.

Timing helps as well. Early runs are cooler, traffic is lighter and the service entrances at hospitals and malls are quieter. Where a truck is doing the movement rather than a van, the city’s road access windows come into it too, and those are set out in Dubai truck timings.
