Monnit Remote Monitoring Solutions for Walk-In Coolers

An essential part of many restaurants, cafeterias, and convenience stores is the popular walk-in cooler. Proper maintenance to your walk-in cooler will not only save you money and frustration but may also keep you in business. As you know, your walk-in refrigerator is not like your standard fridge at home. Not only are they larger, but they also manage their temperatures differently and require more maintenance.

Problems Arising From Walk-in Cooler Failure

Restaraunt owners know that having your walk-in cooler fail may not only negatively affect your business but your reputation as well. You can save time and money by performing regular maintenance using a system that automatically monitors your facilities, and you can focus on what matters most: growing and improving your business. Your staff will be confident knowing that their food and resources will be protected from cold damage, spoilage, and will solidify your reputation as a reliable business and individual.

Here are three simple steps to stay up and running, prevent food waste and keep your utility bills low.

  • Cleanliness: Keep your floor and surrounding areas free of debris, and clean up any spills as soon as possible. Turn the fan off and clean with a soft cloth. Overworking your fan will shorten the life of your cooler. To prevent your fan from breaking down or raising your utility bill, you can monitor its energy consumption by using a Monnit Wireless AC Current Meter. Perform quarterly maintenance on evaporator coils and blades, as well, and replace damaged items as needed. Keeping these things clean will also allow proper airflow for your unit.
  • Hinges & Closers: Most kitchen employees are too busy to ensure the cooler doors closes properly. Monnit Wireless Open/Closed Sensor can provide information on the status of a door. This sensor will allow you to know if a door has been left open. 
  • Monitor Temperatures: For the most accurate temperature reading for your cooler we recommend the Monnit Wireless Temperature Sensor with the Glass Bead Temperature Buffer Vial. This wireless sensor will buffer any momentary fluctuations in temperatures that may be caused by standard operations (defrost cycles, the opening of doors, and fans circulating air). This sensor allows more accurate temperature data to be captured and prevent false alarms from being sent.

All Monnit Wireless Sensors can send notifications through text, voice and email with no monthly fees required. Our Local Alert Device is recommended to notify others if temperatures are fluctuating or if the door is ajar too long in your cooler. The local alert system has an LCD display for custom messaging and sensor reading, as well as an audible alarm and flashing LED.

The IoT Solution

The Internet of Things enables you to use sensors to monitor different conditions in any environment, which when paired with your refrigerator/freezer, can potentially save you thousands of dollars in unnecessary damages and product loss. A simple refrigerator monitor can make a big difference. For a long time, the available monitoring systems were too expensive and difficult to use.  This has since changed with Monnit’s affordable remote monitoring system, which makes it easy to monitor all of your walk-in coolers at once, from anywhere, at any time.

Why It Matters

We live in the most competitive market in history. Remote monitoring systems are still relatively new, so most businesses still don’t know about them, or just haven’t implemented them yet (primarily because they haven’t found a cost-effective solution to meet their needs). Because problems coming from machine failure, such as food spoilage can destroy your reputation, protecting walk-in cooler systems are mandatory for maintaining customer trust. As a result, you have the unique opportunity to enhance your competitive advantage and become a leader in your field, with a strong reputation to build on.


The Internet of Things provides an enormous opportunity to protect your facilities, attract customers, increase profits, and scale your business. Now you have a better understanding of how you can use Monnit and the Internet of Things, to be a competitive force in today’s market.

The Monnit Remote Monitoring System is the most intuitive, reliable, and cost-effective solution on the market. For more information, visit our website:
