Cold Room Failing at Night? Know Before the Food Is Lost

Short answer

Saudi restaurant requirements, built on SFDA food rules, say chilled food must be stored at 0 to 4 °C, frozen food below -18 °C, and chilled food held above 4 °C for more than two hours during a power cut must be thrown away. Continuous sensors with alerts catch a failure inside that window, when a twice-daily paper log cannot.

Key takeaways

The 2025 restaurant requirements from the Ministry of Municipalities and Housing set chilled storage at 0 to 4 °C, frozen storage below -18 °C, and ambient stores at 15 to 25 °C with 60 to 65% humidity.
During a power cut, chilled food that stayed above 4 °C for more than two hours must be discarded, so the useful question is how fast someone learns that the cold room is warming.
Monitor every cold room, freezer and dry store, place the sensor away from the door and the evaporator fan, and add a short hold time so door openings do not trigger false alarms.
Readings logged every few minutes give the inspection record the requirements ask for at receiving, and a full history for any night the cold room failed.
ENTEK delivers Temperature and Humidity as a project: sensors come through the ENTEK marketplace or an RFQ, and alerts go by email, SMS or WhatsApp within about a minute.

01What the Saudi rules ask of a restaurant cold room

The clearest reference for a Saudi restaurant is the Restaurant Requirements document issued by the Ministry of Municipalities and Housing in 2025. Its food safety section says it follows the laws and technical regulations of the Saudi Food and Drug Authority (SFDA). For storage, it sets three bands. Chilled food is kept at 0 to 4 °C. Frozen food is kept below -18 °C. Food stored at room temperature is kept between 15 and 25 °C, and the humidity in those dry stores should stay between 60 and 65%. At receiving, frozen deliveries must not be warmer than -18 °C and chilled deliveries must not exceed 4 °C, or the restaurant should refuse them. Chilled food should not stay out of the fridge for more than 20 minutes while it is moved to storage. The same section points to two SFDA technical regulations for chilled and frozen food, SFDA.FD/GSO 323 and SFDA.FD/GSO 2504.

02The two-hour rule and why a paper log misses it

One clause changes how a kitchen should think about monitoring. During a power cut, the requirements say not to open fridge and freezer doors, and to discard all chilled food that was held above 4 °C for more than two hours. Displayed chilled food must also be used within two hours of leaving the fridge. So the real limit is time above 4 °C, not a single reading. A paper log filled at opening and closing cannot show that time. Take an example: a cold room holds SAR 15,000 of meat, poultry and dairy. The compressor stops at 11:30 pm and the next check is at 7 am. By then the room has been warm for hours, nobody knows when it crossed 4 °C, and the safe decision is to throw the stock away. With a sensor and an alert, the duty manager hears about it within minutes and still has most of the two hours to move the food to another fridge.

03What to monitor and where to place the sensors

Start with a list of every cold space, not only the walk-in cold room. A typical restaurant has a chilled cold room, a freezer room or chest freezers, reach-in fridges on the line, a display fridge, and a dry store. Each one gets its own sensor and its own limits, because one average for the whole kitchen hides the unit that is failing. Measure temperature everywhere, and humidity in the dry store, where the requirements set 60 to 65%. Placement matters as much as the sensor. Keep it away from the door, where every delivery causes a short spike, and away from the cold air coming out of the evaporator fan, which reads colder than the food. Mount it at shelf height in the middle of the room, where most stock sits. In a catering kitchen that cooks for events, add a sensor to the blast chiller or cooling fridge, since cooked food must drop below 10 °C within two hours and then be held at 4 °C.

04Alert settings that catch failures without false alarms

An alert that fires every time a chef opens the door will be ignored within a week. The fix is a hold time: the reading must stay outside the limit for a set number of minutes before anyone is told. For a chilled cold room, a warning after 15 minutes above 4 °C covers a long delivery, and a critical alert after 60 minutes still leaves an hour inside the two-hour rule. Freezers need a longer hold, because defrost cycles and door openings lift the air temperature for a short time. Add a low limit too: a chilled room below 0 °C can freeze produce and dairy. Add a no-signal rule, because a sensor that stops reporting is a problem you should hear about. Send the warning to the kitchen supervisor and the critical alert to the manager. The table below gives example settings to start from; adjust them after two weeks of real readings from your own rooms.

05Records for inspections and for your own decisions

The restaurant requirements ask the kitchen to check the temperature of high-risk food at receiving, record it, and keep the documents that prove it. The SFDA guide for food transport goes further for vehicles: refrigerator and freezer readings must be recorded continuously and kept long enough to serve as a reference, and chilled meat and poultry must travel at no more than 5 °C. A sensor that logs every few minutes gives you that kind of history for every room, without anyone writing it down. It also answers questions a paper log cannot: when did the freezer start warming, how long was the cold room above 4 °C last Thursday night, and which fridge drifts every afternoon in summer. Keep the report simple. For each zone, show the limits, the minimum, maximum and average for the period, and every time the zone left its range, with the start time, end time and who acknowledged the alert.

06How ENTEK delivers cold room monitoring

At ENTEK, Temperature and Humidity is delivered as a project, not as a ready subscription. ENTEK reviews your kitchen, lists the cold rooms, freezers and stores to cover, and scopes the sensors for each one. The hardware is supplied through the ENTEK marketplace or an RFQ at entek.ai, where verified Saudi suppliers quote for the sensors and installation. Insulated metal walls can weaken a wireless signal, so the survey checks that every sensor can reach the network before the order is placed. Once connected, readings arrive within seconds, each zone gets its own high, low, humidity and no-signal limits, and the rules are checked every 30 seconds. Alerts reach the people you name by email, SMS or WhatsApp, in Arabic or English, within about a minute. You can view the history and download a report for any period. ENTEK does not certify food safety compliance; the records support your own checks and inspections.

Questions

What temperature should a restaurant cold room be in Saudi Arabia?

The 2025 restaurant requirements from the Ministry of Municipalities and Housing set 0 to 4 °C for chilled food and below -18 °C for frozen food. Food kept at room temperature should be between 15 and 25 °C.

The power went off at night. Do I have to throw the food away?

The requirements say to discard chilled food that was held above 4 °C for more than two hours, and to use thawed frozen food right away or discard it. Without a temperature history you cannot show how long the food was warm, which is why continuous logging helps.

Will the alarm go off every time someone opens the cold room door?

Not if you set a hold time. The reading must stay above the limit for a set number of minutes, for example 15 minutes for a chilled room, before a warning is sent. A normal delivery does not trigger it.

How fast will I know if the cold room fails?

With ENTEK, rules are checked every 30 seconds and alerts reach the named people by email, SMS or WhatsApp within about a minute after the hold time you chose has passed.

Does ENTEK make my restaurant compliant with SFDA or municipality rules?

No. ENTEK does not certify compliance. It logs temperatures, sends alerts and produces reports for a chosen period, which support your own checks. Compliance stays with the restaurant and the inspecting authority.

Where do I buy the sensors?

Temperature and Humidity is delivered as a project. ENTEK scopes the sensors for each room, and you get them through the ENTEK marketplace or an RFQ at entek.ai, where verified Saudi suppliers quote for hardware and installation.
