ColdAssure by DVM Book a conversationBook
Live cold chain monitoring

Every fridge. Every hour. Watched.
And a record that proves it.

ColdAssure watches your cold rooms around the clock, tells someone who can act the moment a real problem starts, and keeps the record an inspector will ask for. No noise, no guesswork.

The industrial IoT team behind monitoring deployments for global manufacturers, airports and food groups, bringing the same rigour to UK kitchens.

The gap

Most temperature problems are found too late

Not because the fault is rare. Because nobody is standing in front of the fridge when it happens.

Overnight

A walk in freezer drifts up a few degrees overnight. The building is empty, so nobody sees it. By morning prep it has been warm for hours, with no record of what happened between close and open.

On paper

The prep fridge ran warm for four hours on a Tuesday. The sheet was filled in before service, the next entry the following morning. Nothing was flagged. The inspection was six weeks later.

Across the estate

In one site you catch it on the next check. Across fifteen, the same freezer can sit out of range for most of a day before anyone notices.

A slip at 2am that surfaces at the next stock check is one conversation with an inspector. A slip you saw the moment it happened is another. ColdAssure closes that gap. Curious what the gap costs? Put your own numbers in.

How it works

Nothing for the kitchen to do

Sensors clip on, readings run themselves, and you only hear what matters.

1

Sensors clip on

Wireless, on every fridge and cold room. No wiring, no app to fill in.

2

Readings run themselves

Every few minutes, to a record that can’t be backfilled.

3

Alerts reach you

The right person, the same night, not at the next audit.

4

Action, not door noise

A door left open told apart from a breach that needs someone.

The 2 am story

A real problem, caught while the building was empty

One overnight event from the Tn1 pilot, from first drift to morning, exactly as the system handled it.

Overnight, building empty

The walk in freezer starts to drift

Target −18°C. The temperature creeps upward, reading by reading. On paper, this moment does not exist. The next manual check is at morning prep.

90 minutes in

Sustained breach confirmed

This is no blip. The temperature has held above the safe line long enough to matter, the kind of event that quietly spoils stock.

Moments later

The alert lands on a phone

WhatsApp, straight to the owner: which unit, how warm, for how long. Someone knows, the same night, while there is still time to act.

Next morning

The team walks in knowing everything

The trace rules out the door. Whether it was new stock going in, a clean down or a failing unit, the team knows when it began and how warm it got. The stock decision is made on data instead of guesswork, and the right question gets asked the same morning.

Ever after

The night is on the record

Every reading is kept in a live record that cannot be backfilled. If an inspector ever asks about that night, the answer is a trace, not a memory.

Times shown as elapsed from first drift. Taken from the ten week Tn1 deployment, where the freezer produced four sustained breaches and the record separated the door driven events from the ones that needed a closer look.

What it does

What changes for you

Built for UK food businesses that need to prove the cold chain held.

Covered overnight

Every cold unit read every few minutes, around the clock, even while the building is empty.

Alerts you’ll actually trust

A door left open told apart from a breach that needs someone now. A system that cries wolf gets switched off, so this one stays worth acting on.

You hear it the same night

The right person, the same night, on the channels you already use. Not at the next audit.

Proof when the inspector asks

A record that can’t be backfilled, evidence that stands up to an inspection.

Every site, without calling round

A whole group on one dashboard. Check any site without a single manual round.

Before it becomes a write off

The slow equipment faults a paper check never reveals, caught before they spoil stock.

“We kept our fridge temperatures on paper for years and assumed everything was fine. In ten weeks ColdAssure showed us exactly when it wasn’t, and told the difference between a real fault and a door someone left open. It gives me peace of mind.” Murat Aşkın, Owner, Tn1 Bar & Kitchen

Built to be left alone

Reliable kit, nothing for staff to mind

The hard part is monitoring you can trust. The hardware just sits there and does its job.

The ColdAssure wireless sensor with stainless probes and its gateway beside a fridge interior

Reliable inside a cold room

The sensors reach the dashboard from deep in a metal cold room, over their own long range network. They do not lean on your kitchen network.

Years on a battery

Each sensor runs for years on a single battery. Fit it once and leave it. No charging, no daily handling.

Food grade sensors

Stainless probes built for cold chain use, rated to sit in a fridge or freezer and keep reading, year after year.

Questions

The things operators ask first

How long does setup take?

Minutes per unit. The sensors arrive ready to work, clip onto a shelf in each fridge or cold room, and start reading. No wiring, no engineer visit, no disruption to service.

Does it need our WiFi?

No. The sensors report over their own long range network, built to reach out from deep inside a metal cold room. Nothing touches your kitchen network or your tills, and there is nothing for your IT to set up or maintain.

What is the contract?

A rolling monthly agreement. No long term lock in, no minimum term hiding in the small print. If it is not earning its keep, you stop.

What if a sensor fails?

We replace it. The hardware stays our problem, not yours, for as long as you run the service.

Will staff drown in alarms?

No, and this is the part we care most about. A door left open has a signature of its own, and the system tells it apart from a breach that needs action. Staff only hear about the events worth acting on, which is why the alerts stay trusted instead of switched off.

Does this replace our HACCP paperwork?

It replaces the manual temperature checks with a continuous record that aligns with your HACCP plan and with FSA guidance on temperature monitoring. We monitor and evidence your cold chain, we do not certify it. The compliance call stays yours, made on far better information. If you are staying on paper for now, take the free temperature log template; it is the format an EHO expects to see.

Who is behind ColdAssure?

ColdAssure is built and run by DVM IOT Solutions Ltd, a company registered in England and Wales, number 15438850. The team behind it has spent a decade building industrial monitoring for global manufacturers, airports and food groups, and ColdAssure brings that same engineering to UK kitchens.
