For cold stores, food and drink distributors and 3PL warehouses
BRCGS Storage and Distribution asks for alarms or recorded checks on every controlled store, mapped temperature distribution, calibrated sensors and time limits outside control. We cover a single cold store or an estate of depots on one record. Nestlé's UK warehouse runs at 99% optimal temperature performance on JTF.

What auditors ask you
Auditors from BRCGS, your customers and the local authority ask the same questions about temperature. Clause numbers are checked against the published standards; the wording is paraphrased.
Temperature-controlled stores with recording equipment and suitable alarms, or recorded manual checks, typically at least every 4 hours.
Read the guideUniformity of temperature in controlled stores established, validated and verified at a frequency based on risk, and re-established after equipment changes (7.3.8).
Read the guideMaximum times product may spend outside temperature control, set for loading, unloading and staging.
Read the guideDevices checked at a set frequency and traceable to a national standard, with action on product, and under S&D the product owner told, when one is found inaccurate.

What we monitor
Over 95% optimal performance across a 25-site food distributor, on one record.
Sensors where the stock sits, with door contacts on the doors that get left open.
Each zone with its own limits, so a summer heatwave or a slow load shows up before a customer complaint does.
Chilled drinks, dairy and multi-temperature stock, each zone to the limit its product specification sets.
Monitored on the same platform as the store, so a load's record runs from dock to drop. See food and beverage transport.
Energy monitoring on compressors, condensers and defrost, beside the cold store temperatures, so a plant working harder shows up early. See energy monitoring and our freezer door monitoring case study.

How JTF helps
Sealed Node+ sensors for cold rooms and freezers, probes for blast freezers and tanks, door sensors, and gateways built for warehouses and yards. Node+ embedded and Node+ PT100 are designed to meet EN 12830:2018, accuracy class 0.2.

Questions
Not in every case. It accepts recording equipment with alarms or recorded manual checks. Auditors and retail customers increasingly expect continuous records, and a manual check can't catch an overnight failure.
Yes. Each site keeps its own limits and alarm routes, and head office sees every site on one record. One 25-site food distributor sees Over 95% optimal performance on JTF, many sites higher.
BRCGS asks for a frequency based on risk and gives no figure. Our recommendation: map each controlled store at commissioning, after any change to layout or refrigeration, and at least every three years. Temperature mapping is a JTF managed service: we plan, run and report the study, then place the monitoring at the hot and cold spots it finds.
Not if the delay is right. We set each store's delay from its own defrost and door recovery data, so a normal defrost is recorded but doesn't page anyone, and a defrost that doesn't finish still does. Our frozen food guidance gives the figures we start from.
Yes, on the same platform as the store, so you can show an auditor or customer the temperature of a load from dispatch to delivery. See food and beverage transport.
