Autonomous monitoring eliminates shrinkage and labor.
Beyond theft Nimbus 9’s Cold Storage Management Solution addresses the other source of shrinkage: spoilage. Equipment failure is the most common cause of spoilage in restaurants. While restaurant staff is required by local health ordinances to check the temperatures of all Freezers and Refrigerators multiple times a day it rarely happens.
The CSM temperature sensors continuously monitor the temperature of refrigerators and freezers logging the temperature no less than every 5 minutes. All temperature reads are automatically sent wirelessly to the CSM platform where they are stored in a time series database.
Nimbus 9’s Cold Storage Monitoring application monitors numerous variables from equipment and the environment in real-time.
TEMPERATURE
Measuring and controlling of temperature is critical. It has been demonstrated that the comfort level of air temperature has measurable impacts on heart rate, respiration, exhaled carbon dioxide concentrations, and mood and sick building syndrome symptoms, as well as work performance.
Detection Range: -35°C to 65°C (32°F to 113°F)
HUMIDITY
The recommended average relative humidity for indoors is 30 to 50%, when the outside temperature is 20°F or more. Indoor relative humidity above 60% creates an ideal environment for mold and mildew. These contaminants pose a threat to the health of building occupants and cost as well as time consuming remediation for building owners.
Detection Range: 30% to 85% non-condensing. RH +/-5%
DOOR CONTACTS
The use of door contacts deliver significant benefits for cold storage monitoring applications. Door contacts not only provide warnings of refrigerator and freezer doors being left open accidentally but can serve to alert management of product leaving out the back door.
POWER METERING
Power metering of refrigeration systems provides key insights for performance and maintenance. The electrical signatures of refrigeration systems are extremely consistent where defrost cycle intervals track like a Swiss watch. By monitoring the electrical signature anomalies indicating failing compressors and other components can be detected and fixed before complete failure.
CARBON DIOXIDE
At room temperature carbon dioxide is a colorless, odorless, faintly acidic-tasting, non-flammable gas. Carbon dioxide at levels that are unusually high indoors may cause occupants to grow drowsy, to get headaches, or to function at lower activity levels. CO2 leaks from cylinders and bulk storage tanks can result in oxygen deprivation and death. The maximum indoor CO2 level considered acceptable is 1000 ppm.
Detection Range: 400 – 5000 ppm
Shrinkage Prevention
THRESHOLD MONITORING
EQM provides managers and facilities personnel the ability to configure Alerts around Min/Max thresholds for each freezer and refrigerator. Overtemp and undertemp conditions are closely monitored and alerts can quickly notify management of failing equipment that can lead to spoilage.
PERMITTED & PROHIBITED TIMES
One of the key features to prevent shrinkage through theft is the monitoring of doors through which product can leave an establishment.
Restaurateurs are able to designate within the EQM solution when the opening of select doors is permitted or prohibited.
EQM uses door contacts to track and log every single time a door is opened or closed. When doors are opened during Prohibited times managers and owners can receive real-time text notifications.
CONFIGURABLE ALERTS
Cold Storage Monitoring can include a 105 decibel Siren that can be configured to sound when doors are opened during Prohibited Times, walk-in doors are left open too long, etc. These features serve to prevent shrinkage through theft by alerting the Management Team either through Siren, Text or a combination of alerts.
“Nimbus 9’s Cold Storage Monitoring application has eliminated over 30 minutes of labor daily per restaurant while ensuring more accurate compliance with health department requirements. Additionally the real-time alerts for overtemp as well as door openings during prohibited times has eliminated costly shrinkage through spoilage and theft.”
