Temperature Monitoring for Cold Chain Fleets & Cold Stores

Wireless temperature monitoring and EN 12830-compliant recording for fridge vans, trailers and static cold stores — with alerts the moment a unit drifts out of range and delivery-level evidence when a customer disputes a load. Fitted and supported across the UK by one partner.

Definition

What is cold chain temperature monitoring?

Cold chain temperature monitoring continuously records the temperature of refrigerated vehicles, trailers and storage using wireless sensors, and stores that record so you can prove goods were kept within specification from depot to door. Modern systems use battery-powered Bluetooth (BLE) sensors that report through a vehicle tracking device or gateway, generate alerts when temperatures move outside set limits, and produce audit-ready records that support HACCP-style due-diligence documentation.

How it works

How it works

1. Wireless BLE sensors

Placed in the fridge body, trailer compartment or cold room — no cabling into the load space, and multi-year batteries mean fit-and-forget.

2. EN 12830-compliant recording

Captures temperature at set intervals, to the standard expected for temperature recording in transport and storage of temperature-sensitive goods.

3. Live data and alerts

Data flows to the Vision Telematics platform: set thresholds per compartment, and get notified the moment a unit drifts out of range — a door left open, a fridge unit fault, a failed pre-cool.

4. Evidence on demand

Pull the temperature trace for a specific delivery, vehicle and time window — the record that settles a rejected-load dispute in minutes rather than days.

The payback

Why operators fit temperature monitoring

Win rejected-load disputes

When a consignee rejects a pallet “because it arrived warm”, the operator without records pays. A delivery-level temperature trace shows exactly what the load experienced on your watch — often the difference between absorbing a costly claim and closing the dispute same-day.

Catch excursions before they cost you the load

An overnight fridge failure discovered at 6 a.m. is a written-off trailer of stock. Threshold alerts turn it into a 1 a.m. phone call and a saved load.

Audit-ready records without paperwork

Continuous EN 12830-compliant records support HACCP-style due-diligence documentation for food businesses — automatically, instead of drivers writing temperatures on run sheets.

One system, vehicles and buildings

The same sensor estate covers fridge vans, refrigerated trailers and static cold stores — one platform, one set of alerts, one audit trail.

Who it helps

Who benefits

Fleet & Transport Managers

No more chasing run sheets; excursion alerts route to whoever’s on call, and every customer query is answered from the platform.

Owners & CEOs

Protects the contracts — major retailers and food-service customers increasingly expect continuous temperature evidence as a condition of supply.

CFOs

Small per-asset hardware cost against write-offs, rejected loads and insurance claims that each dwarf it; multi-year batteries keep the whole-life cost flat.

Fleet Directors

A single monitoring standard across owned, rented and mixed refrigeration assets, with retrofit fitting that doesn’t take vehicles off the road for long.

In practice

Use cases

Chilled and frozen distribution

Multi-drop fridge vans and dual-compartment trailers, monitored per compartment — see food & beverage fleets.

Static cold stores and prep rooms

The same BLE sensors monitoring buildings, with out-of-hours alerts.

Rented and third-party trailers

Battery sensors travel with the asset — no wiring into someone else’s fridge unit.

Pharmaceutical & high-value goods

Continuous records for temperature-sensitive goods where an excursion means disposal, not discount.

Combined with asset tracking

Know where the trailer is and what temperature it’s running — one device estate, one platform. See the asset tracking range.

Alongside Bluetooth tags

Temperature sensors share the same gateways as Bluetooth asset tags on roll-cages and returnable kit.

Pricing

How pricing works

You’re buying sensors (per compartment or room), a reporting gateway or tracker per vehicle where needed, and a platform subscription — so price follows your asset list, not a generic tier. Tell us how many vehicles, trailers and rooms you need covered and whether you already run our tracking hardware, and we’ll return an itemised quote. Get a quote →

FAQs

Temperature monitoring questions, answered

What is EN 12830 and do I need it?

EN 12830 is the European standard for temperature recorders used in the transport and storage of temperature-sensitive goods. If you carry chilled or frozen food commercially, records from an EN 12830-compliant recorder are what auditors and customers expect.

How do wireless temperature sensors get data out of a sealed fridge body?

The BLE sensors transmit to a gateway or tracking device on the vehicle, which sends readings over the mobile network to the platform — no cables through the fridge wall.

How long do the sensor batteries last?

Multiple years on the fitted battery, depending on reporting interval — designed to be fitted and left in place rather than recharged.

Can I get an alert if a fridge fails overnight?

Yes — set temperature thresholds per compartment or room and alerts are raised the moment readings move out of range, at any hour.

Can it prove the temperature for one specific delivery?

Yes — records are time-stamped and tied to the vehicle or asset, so you can pull the trace for a specific delivery window as evidence in a rejected-load dispute.

Does it work for cold stores as well as vehicles?

The same sensors monitor static cold rooms, prep areas and warehouses, feeding the same platform and alerting rules as your vehicles.

Cover every fridge, trailer and cold room.
