Integration of AIRSYS Spray Technology with QLOE Dielectric Coolant

This white paper presents the integration of AIRSYS's LiquidRack spray-based liquid cooling solution with Oleon's QLOE dielectric coolant, aimed at enhancing cooling efficiency in high-density IT infrastructures. The document outlines the technical specifications and operational performance of the LiquidRack system, which features ten modular server cassettes capable of supporting up to 17.5 kW per server. It details the cooling capacities achieved with both dry coolers and chillers, emphasizing the use of QLOE 8313, a bio-based synthetic ester dielectric coolant. The paper evaluates the coolant's physical, thermal, and dielectric properties, confirming compliance with relevant standards and specifications. Performance metrics indicate that QLOE 8313 maintains optimal thermal management while ensuring long-term safety and environmental compatibility. The findings underscore the potential of this partnership to advance sustainable cooling solutions in data centers, highlighting the successful operational stability and reliability of the integrated system over a three-month evaluation period.
