KOOLZONE: Real-time refrigeration temperature monitoring
Uninterrupted data connectivity for refrigeration monitoring
Koolzone enhances smart refrigeration monitoring with M2M Intelligence connectivity
Roaming SIM card solution provides failsafe connectivity for firm’s global client base
KoolZone provides real-time refrigeration monitoring technology for a global hospitality, pharmaceutical and healthcare customer base. From restaurants and bars keeping food and drinks at the right temperature, to the strict storage of medicines and laboratory stocks within strict safety parameters, KoolZone ensures a consistent stream of real-time temperature data.
Sensors placed inside refrigeration and freezer units take automatic temperature readings up to 250 times every day, with the resulting data stored securely in the cloud and accessible from any smartphone or tablet. Instant alerts are triggered via SMS or email if temperatures fluctuate beyond a predefined range, optimising reaction and remedy times.
The company was founded by Steve Miller, who first had the idea to develop the technology when manually managing the storage of refrigerated insulin at home for his young son, who was diagnosed with type 1 diabetes aged two.
We now use M2M SIM cards across all of our new deployments. The connectivity has been so reliable that we’ve stopped worrying about the potential for any interruptions in temperature data streaming. We put the card in our gateway confident that the roaming SIM will keep the information flowing. The M2M team also provides a personal service and is quick to respond to queries. They frequently work with us to reduce and optimize our data costs, which is important as we move into new markets, such as environmental monitoring.
KoolZone's sensors operate using a high-powered wireless signal (up to 20km range) to communicate with a local gateway outside the refrigerator, which streams temperature data to the cloud. As well as ensuring high quality food and drink for customers, hospitality businesses use evidence from archived temperature logs to remain compliant with food safety legislation.
For many healthcare applications accurate, real-time temperature information is crucial to safeguard patient welfare, as well as protect against significant cost. Steve Miller, Managing Director of KoolZone explains: "Many of our pharmaceutical and healthcare customers need to store medicines at a constant and exact temperature for them to remain safe and effective – sometimes many degrees below zero. Even seemingly tiny temperature fluctuations can damage sensitive medicines and chemicals, rendering them useless very quickly.
In addition, these medicines are often very expensive, so it's possible to waste a million pounds worth of stock in a single fridge through poor temperature management."
Originally, KoolZone used wireless connectivity to transfer temperature data from gateway to cloud but wanted to add SIM card technology to increase installation flexibility and streaming reliability. It needed the right partner to deliver this additional connectivity.
KoolZone invited a handful of top IoT connectivity specialists to tender for the project, with M2M Intelligence emerging as the winner – proposing a tailored roaming SIM card solution, backed up by significant support and service.
After a successful trial, KoolZone ordered SIM cards to be used across its global estate of connected gateways – all controlled through the M2M Insight management platform.
Roaming SIM cards from M2M Intelligence have delivered a second layer of reliability and extra installation flexibility for KoolZone. "Having roaming SIM cards inside our gateways gives us several benefits," explains Miller. "Firstly, we can activate connectivity instantly, even before the additional ethernet connection is established. This is particularly useful in awkward, remote or hard-to-access deployment scenarios.
"Secondly, combining roaming SIM cards – which automatically use the best possible network signal available – with wired ethernet means our customers benefit from almost uninterruptable connectivity. Data is accurate and available 24/7.
"Hospitality businesses can ensure food and ingredients are the right temperature for customers and automate food safety compliance processes, while healthcare professionals have peace-of-mind that stored medicines are at a safe temperature and will work as expected."
This extra layer of connectivity protection is especially important for KoolZone customers who need to provide temperature logs for safety audits and regulatory compliance purposes. M2M's roaming SIM solution also helps KoolZone provide increased assurance to customers with vehicle-based refrigeration requirements, as the card automatically finds and uses the best available signal for mobile temperature monitoring and geolocation information.
The team also uses the intuitive M2M Insight platform, to manage its SIM estate. Individual cards can be grouped by tariff, tagged with extra contextual information, and monitored for data and performance. KoolZone engineers can use the platform to activate new cards, change tariffs and suspend SIMs as needed. This remote maintenance and service provision saves KoolZone time and reduces cost.
Steve concludes: “We now use M2M SIM cards across all of our new deployments. The connectivity has been so reliable that we’ve stopped worrying about the potential for any interruptions in temperature data streaming. We put the card in our gateway confident that the roaming SIM will keep the information flowing.
