Tecnair Develops Liquid Cooling CDU for High Density AI and HPC Data Centres

Tecnair, a Panasonic company, has launched its new high‑performance Coolant Distribution Units (CDUs). These new units address the rising thermal demands created by AI and high‑performance computing. As AI and HPC densities push traditional air‑cooling systems beyond their limits, the new CDU portfolio delivers a robust, efficient, and scalable liquid‑cooling platform that integrates seamlessly with existing infrastructure, supporting data centre operators and hyperscalers in their transition to sustainable, high‑density operations. 

With decades of precision cooling expertise, the CDU’s tackle one of the most urgent challenges facing data centre operators today: how to efficiently cool rack densities that now routinely exceed 50 kW and are climbing towards 100 kW and beyond. The CDU range supports both direct-to-chip and immersion cooling architectures, delivering reliable liquid cooling with the monitoring, redundancy, and scalability required for mission-critical 24/7 operations.  

The launch of the new CDU range reinforces Panasonic’s commitment to equipping data‑centre operators, engineers and partners with the advanced thermal‑management technologies required to enable the sector’s rapid transition toward high‑density, low‑carbon infrastructure. 

Designed for Efficiency and Reliability 

The range delivers a range of features, designed to protect sensitive IT equipment while maximizing energy efficiency.

Features

• Industry-leading efficiency: Achieves pPUE as low as 1.02 through advanced free‑cooling coils and micro‑channel heat‑exchanger (MCHE) technology, significantly reducing energy consumption versus traditional air‑cooled designs. 

• Flexible, scalable, and highly reliable, the CDU is available in 400 and  800 kW with modular networking to support deployments ranging from edge environments to hyperscale data centres. Designed for continuous 24/7 operation, its fully redundant architecture includes pumps, power supplies, sensors, and a failover system to ensure uninterrupted cooling during maintenance or component failure. 

• Intelligent monitoring and diagnostics: Integrated Modbus BMS control with embedded sensors provides real‑time monitoring of temperature, pressure, flow rate, water level, leak detection, and system alarms, all accessible via a wide intuitive touchscreen interface for seamless local and remote management. 

A Complete System Approach with Seamless Integration 

Recognising that liquid cooling extends beyond the CDU itself, Panasonic offers an integrated system solution incorporating a Panasonic free‑cooling chiller using R1234ze, a refrigerant with a low GWP of 1,37 (AR6) [1], and fast‑restart capability that further enhances suitability for edge environments.  
These models feature a free‑cooling function, which generates chilled water using low outdoor temperatures (down to –10°C), delivering high energy efficiency. 

Availability and Next Steps 

The CDU range will be available across European markets from Autumn 2026.
