The InSight system provides peace of mind with remote notifications by text or email to help protect irreplaceable samples.
1. Monitor critical parameters
Finding the right monitoring system to better maintain sample integrity in cold storage can be a challenge. The School of Public Health at a large, prestigious research academy had an aging fleet of ultralow temperature (ULT) freezers. Challenges included increased cost of usage, unpredictable maintenance costs, and sample integrity threatened by the risk of equipment failure.
Many factors can affect equipment performance, including frequency of maintenance, usage behavior, power fluctuations, and mechanical stress over time. Based on a diverse set of customers, indications show 30–50 percent of even well-maintained ULTs in the US are operating out-of-spec and exhibiting signs of mechanical stress. An average of 12 percent of ULTs will have a significant alarm condition each year. If the instruments fail to maintain settings accurately, then scientific products are at risk.
In addition to sample risk, stressed ULTs waste significant amounts of energy. A ULT freezer that’s 10 years old or older can consume as much energy as a house: on average, 30 kWh/day. Today’s Thermo Scientific™ ULT freezers with green, hydrocarbon (HC) refrigerants reduce CO2 emissions by over 30 percent* and can save over 50 percent on energy usage and costs. To support a retirement and replacement program, the emergency management director at the academy analyzed their aging install base with a focus on sustainability and asset management. They wanted a better system that offered state-of-the-art monitoring and alarms for temperature fluctuations, power outages and surges, energy consumption, and more.
A monitoring solution for aging ULTs
The Thermo Scientific™ InSight system provided the monitoring solution they needed, with multiple benefits such as wireless monitoring and asset management. The emergency management director’s analysis of operating costs, unplanned maintenance costs, and product and sample loss provided realized value of their return on investment (ROI).
Proactive data analytics
The InSight system assists in managing fleet assets by providing information from multiple sensor parameters. The proactive data analytics allow visibility into equipment that requires service and preventive maintenance.
Details energy usage to support sustainability
This monitoring solution supports sustainability efforts by listing assets according to energy efficiency, calculating energy savings attributed to proactive maintenance, and providing kilowatt-hour (kWh) consumption information.
Notifies the customer remotely when an alarm sounds
InSight ULTs provide peace of mind with remote notification by text and/or email to help protect irreplaceable samples.
By implementing the InSight solution, the customer now has a ULT fleet operating at sustainable levels and the data to support equipment retirement programs with focused fleet identification. Retiring old ULTs can result in energy cost savings of $1,000 per ULT per year, on average. And the hydrocarbon refrigerants, in addition to being better for the environment, promote lower pressures and temperatures in the refrigeration system. This drastically improves the mechanical wear and tear on the refrigeration components, extending the system's life.
