Airedale by Modine, a brand of Modine (NYSE: MOD), announced the TurboChill 3+MW, a new high-capacity hybrid air-cooled chiller designed to support rising cooling demands in GPU-powered AI data centers. The system expands the company’s TurboChill platform with more than 3 MW of heat-rejection capacity and an extended free-cooling operating range to reduce mechanical cooling hours and overall energy consumption.
The TurboChill 3+MW targets next-generation facilities facing higher rack densities and mixed thermal requirements. It operates across a wide range of facility water temperatures, enabling operators to maximize free cooling where climate conditions allow while maintaining precise control for temperature-sensitive accelerators. Modine positions the system as a practical alternative to architectures that rely solely on dry coolers or elevated liquid supply temperatures.
According to the company, global AI deployments require resilient cooling designs that can handle heat waves, air recirculation, and partial conversions to high-density racks within existing data halls. By combining free cooling with refrigerant-based mechanical cooling, TurboChill 3+MW aims to provide predictable return water temperatures, helping operators manage peak loads while maintaining data center water usage effectiveness (WUE) and power usage effectiveness (PUE).
- Hybrid air-cooled chiller with 3+MW heat-rejection capacity
- Expanded free-cooling range to reduce compressor runtime
- Designed for mixed rack densities and varied facility water temperatures
- Supports global deployments facing ambient variability and peak thermal events
“There is speculation that chillers may no longer be required as next-generation chips are designed to operate at higher temperatures,” said Art Laszlo, Group Vice President of Global Data Centers at Modine. “However, customers continue to demand proven cooling and reliability to protect their investments, especially when high performance compute is installed on site. Airedale by Modine’s TurboChill platform delivers an ideal hybrid solution by maximizing free cooling where conditions allow, while deploying mechanical cooling to manage peak heat loads and the reliability customers expect.”
🌐 Analysis
Hybrid cooling architectures continue to gain traction as AI data centers balance aggressive density targets with operational risk. Modine’s TurboChill expansion aligns with broader industry moves toward combining liquid cooling at the rack with resilient facility-level heat rejection, rather than eliminating chillers altogether. Competitors across the cooling ecosystem are also emphasizing hybrid and scalable approaches as operators plan global AI rollouts that must perform consistently across diverse climates and retrofit scenarios.
