Quasar and HALIAS partner to unlock a new level of efficiency for the mining industry

New York, December 21st, 2021: By leveraging the Quasar platform, HALIAS Technologies can deliver turn-key solutions for its heavy-industry customers. This cooperation enabled HALIAS to deliver fully integrated solutions to, in particular, the mining industry.

Asset health and product quality have always been a critical concern for the mining industry, which needs to optimize its production and constantly minimize asset wear and tear. With intelligent monitoring, it is possible to give powerful insights that deliver a new level of efficiency.

By leveraging Quasar, HALIAS can deliver unlimited data management capabilities from the Edge to the Cloud that grow with the customers' needs. HALIAS turn-key solutions propel customers to the next generation of asset health.

Quasar is a software platform that can capture, store, and extract features from event-driven data. Its capabilities in terms of performance and compression are outmatched.

"Storing and centralizing data is a challenge that QuasarDB solves very well. Thanks to the integration, our customers will benefit from its outstanding technology instead of combining heterogeneous database solutions", says Laurent Testard from HALIAS Technologies. "In addition, QuasarDB gave us all the support needed, making the pilot project very successful. QuasarDB replaces three distinct components we were using, greatly simplifying our architecture and thus lowering maintenance costs".

"Quasar is the universal adapter between raw sensor data and artificial intelligence. Quasar solves all the data engineering challenges related to capturing large volumes of event data. Thanks to our unique compression technology, storage is extremely cost-effective. Last but not least, Quasar enables users to extract features from raw data in real-time, removing the need for custom scripts or third-party tools. The combination  delivers a new level of performance and greatly simplifies software architectures, resulting in tremendous value for the customers." says Edouard Alligand, Founder and CEO of Quasar.

"We are thrilled to partner with HALIAS Technologies. OEM licensing is a key component of our strategy. We understand our partners help us bring the QuasarDB technologies to more users."

In 2021 Quasar adoption grew significantly. Major US-based manufacturing companies have been using Quasar to successfully generate millions of dollars of value. With the OEM licensing, the Quasar technology increases its reach to benefit businesses of all sizes.
