Reefer and cooling units on the AP-7 at Granollers

Reefer and cooling units

When the fridge stops with meat, fish or pharmaceuticals inside, the clock is running against you. We handle unit start failures, belts and pulleys, temperature sensors, pressure switches and gas loss, plus Thermo King and Carrier Transicold alarm codes. These jobs go to the front of the queue, because the load does not wait.

When a refrigeration unit fails it is not just a truck that stops: it is an entire load. Most thermal breakdowns on the road are electrical (connectors, blower motors, auxiliary batteries) or refrigerant-side (slow leaks in stone-pelted condensers), and both families allow a good share of roadside repair.

Before opening anything, read the unit display: Carrier and Thermo King alarm codes say a lot (low voltage, high discharge pressure, start failure). With the code in hand the intervention narrows and saves half an hour of blind testing.

What never to do

Do not open the box to check the load
Do not reset the unit repeatedly — it wipes the fault history
Do not wait until the cold chain is already broken to call

Temperature alarm. The display reports deviation from setpoint: act before the load climbs out of chain.

How it works

Read the alarm code, check supply voltages and earths, inspect condenser and evaporator visually. Electrical faults get repaired from portable stock; refrigerant leaks are traced with an electronic detector and recharged with exactly the gas and charge stated on the unit plate, leaving a temperature log for the receiver.

Service

24 h reefer callout. Diagnosis + electrical or leak repair + temperature report.

Blow the condenser clean with compressed air weekly in hot weather and check the unit's belt tensioner: a dirty condenser spikes pressures and kills expensive compressors.

Questions about this stretch

Can you come into my warehouse or estate if I can exit the motorway?

Yes — that's the preferred option around Granollers: we attend inside estates and yards whenever the truck can still move a few kilometres. Leaving the motorway also saves waiting time on the shoulder.

How does Vallès traffic affect your arrival time?

Rush hours (7–9:30 and 17–20) add genuine delay. You get an honest window on the call and, if you're near an exit, we propose the exact spot to meet.

Do you cover the C-60 towards Mataró and the C-17 towards Vic?

Yes, both axes start from our exits. Tell us the road and kilometre marker in the first message so we can plan the van's route properly.
