Food, Cold Storage & Retail
Keep the cold chain unbroken
Continuous temperature and humidity monitoring for food production, cold rooms, chilled and frozen display and retail environments, helping you protect stock, evidence HACCP compliance and act the moment conditions drift.
Eltek has monitored regulated, temperature-controlled storage across the UK for over 40 years.
Why Eltek
Monitoring built for cold rooms, chilled display and retail estates
From cold rooms and walk-in chillers to chilled display cabinets, retail stockrooms and distribution cold stores, Eltek monitors temperature and humidity continuously, wired or wireless, on one connected platform. Battery-powered GenII transmitters go where cabling is impractical across a busy shop floor or a multi-site estate, alarms escalate a breach the moment it happens, and time-stamped records keep HACCP evidence to hand, backed by over 40 years monitoring temperature-controlled storage.
How do you monitor temperature in food cold storage and retail environments?
Food cold storage and retail monitoring uses calibrated sensors to track temperature and humidity continuously across cold rooms, chillers, freezers and chilled display, rather than by manual spot checks. Eltek’s wired and wireless system alarms a breach by SMS and email and keeps time-stamped, audit-ready records that evidence HACCP compliance and protect stock.
Continuous cold room, chiller and freezer monitoring
Monitor cold rooms, walk-in chillers, freezers and chilled display cabinets continuously rather than by manual spot checks, so a drift is caught as it happens, not at the next round.
HACCP audit-ready records
Secure, time-stamped records and scheduled reports keep audit-ready HACCP evidence to hand, so inspections and due-diligence checks take less effort.
Real-time alarms on a breach
Instant SMS and email alarms escalate an out-of-tolerance reading, a door left open or a failing compressor to the right person, day or night, so stock is protected before it is lost.
Wireless flexibility for shop floors and stockrooms
Battery-powered GenII transmitters deploy across shop floors, stockrooms and cold stores without disruptive cabling, with repeaters to extend range across large or obstructed sites. Wired probes are available where a permanent connection suits.
One platform across a multi-site estate
Consolidate every store, depot and distribution cold store onto one connected Darca platform, with secure dashboards, trends and reports from anywhere.
The platform
The Darca Solutions Suite
One connected platform, wired and wireless, for monitoring food production, cold storage and retail environments.
Darca Collect
Wireless GenII transmitters, RH/T sensors and repeaters placed across cold rooms, chillers, freezers and chilled display, plus wired probes where a permanent connection suits, the sensing layer for food storage and retail.
Explore
Darca Connect
The SRV450 hub keeps data flowing and SMS450 alarms notify the right person the moment a cold room, freezer or display cabinet drifts out of range.
Explore
Darca Command
Dashboards, trend analysis and audit-ready HACCP reporting so food-safety and facilities teams see every site at a glance, from anywhere.
ExploreProven in cold storage
Watching the cold chain, from the cold store to the shelf
Eltek has monitored temperature-controlled storage across the UK for over 40 years, from chilled and frozen stores to laboratory cold rooms. The same GenII loggers and connected Darca platform that alarm a breach in the moment also keep the time-stamped records that evidence a cold room, freezer or chilled cabinet held its conditions, the proof a food-safety audit or a stock-loss investigation depends on.

ExploreFrequently asked questions
How do you monitor a cold room or walk-in chiller for food safety?
Cold room and chiller monitoring places calibrated sensors inside each unit and logs temperature, and humidity where it matters, continuously rather than by manual spot checks. Eltek monitors cold rooms, walk-in chillers and freezers 24/7 with wired or wireless GenII sensors, holds high and low alarm thresholds aligned to your limits, and escalates a breach by SMS and email, so a drifting unit is caught before stock is affected.
What happens if a cold room door is left open or a compressor fails?
A door left open or a failing compressor is one of the most common causes of a cold-storage excursion, and often goes unnoticed until stock is already at risk. Eltek monitors continuously, so a rising temperature is detected the moment it starts, and alarms escalate to the right person by SMS and email, day or night, with time-delayed alerts to cut nuisance alarms. Every reading is stored as a time-stamped record, so you can both respond in the moment and evidence what happened afterwards.
Can you monitor temperature across a multi-site retail or food-retail estate from one dashboard?
Yes. Eltek consolidates a whole estate onto one connected Darca platform: wireless GenII transmitters and wired sensors collect readings at each store, depot and distribution cold store, hubs and SMS450 alarms escalate any excursion to the right team, and Darca Command gives secure cloud dashboards, trends and reports from anywhere, so a multi-site estate is monitored in one place rather than store by store.
How does continuous monitoring help with HACCP records and due diligence?
Under HACCP, chilled and frozen storage temperatures must be kept within defined limits and recorded, and a food business needs to be able to show it. Eltek monitors these points continuously rather than by occasional checks, alarms the moment a limit is breached, and stores secure, time-stamped records with scheduled reports, so the audit-ready evidence for HACCP and due-diligence reviews is always to hand rather than reconstructed after the fact.
Can you monitor chilled and frozen display cabinets in a store?
Yes. Chilled and frozen display cabinets on a shop floor can be monitored with wireless GenII transmitters, which deploy without disruptive cabling and use repeaters to hold range across a large or obstructed floorplate. Eltek logs cabinet temperatures continuously, alarms an out-of-tolerance reading by SMS and email, and keeps time-stamped records, so display stock is protected and the evidence for a food-safety audit is captured automatically.
