Meeting the Direct Liquid Cooling Challenge: Donaldson’s Answer for Cooling Loops
Hyperscale data centers are redefining cooling standards—making filtration a critical component of the process.
Data Center Coolant Filtration Skid
As direct-to-chip (D2C) liquid cooling becomes mainstream, operators and contractors face an emerging requirement: maintain coolant cleanliness to help protect high-value hardware.
Traditional bag filters, long trusted for coarse filtration, often fall short in this demanding application, struggling with seal integrity, service complexity, particle retention and oversized footprints.
Donaldson’s data center coolant filtration skid was engineered to address these challenges head-on, delivering a compact, scalable and service-friendly solution purpose-built for coolant distribution units (CDUs) and technology cooling systems (TCS).
Why Traditional Bag Filters Often Fall Short
- Seal integrity: Imperfect interfaces may allow fluid bypass, leading to downstream fouling
- Serviceability: Cumbersome changeouts extend maintenance windows
- Footprint pressure: Multi-bag housings consume precious floor space
- Cost & availability: High capital expenditure and slow deliveries can delay project schedules
At the core of Donaldson’s solution is the PP100-HF high-flow pleated filter, designed to provide greater surface area, flow capacity and dirt‑holding performance to help provide improved protection of critical cooling loops over standard size 2 bag filters.
The data below indicates how Donaldson’s PP100-HF filters compare to a common size 2 bag filter based on internal testing under controlled conditions.
- 14.6x larger surface area per element
- 1.4x higher recommended flow rate per element
- 3.5x greater dirt holding capacity (DHC)
- Significantly higher particle retention efficiency
Together, these advantages can help protect your system.
