If you’re like most data center operators, you’re under constant pressure to cut cooling costs and increase efficiency without a full-scale rebuild. The rise of AI and other high-density workloads has shifted conversations toward liquid cooling and advanced thermal strategies. But in that rush, a critical truth often gets overlooked: the fact that some of the biggest efficiency gains come from optimizing what’s already in place.
Fundamentals like airflow accessories, containment, and cabinet finishes may not grab headlines—but they often represent the fastest path to measurable efficiency gains. Together, they help you get more from your current cooling investment while setting the stage for advanced strategies like liquid cooling and heat reuse.
By making airflow management and cabinet design fundamentals work harder, operators can:
- Reduce energy costs without adding new CRAC units
- Extend the life of existing equipment
- Unlock stranded capacity to support higher densities
- Build a stronger foundation for advanced cooling strategies like liquid and hybrid cooling
These three steps may seem simple, but together they can transform cooling performance, reduce operating costs, and prepare your facility for what’s next.
1. Fully Equip Your Cabinets to Prevent Bypass Airflow
Many data centers miss out on a simple yet highly effective way to increase cooling efficiency and save money—properly equipping cabinets with thermal management accessories. These accessories are often the "low-hanging fruit" of data center management: easy to implement, inexpensive, and frequently overlooked.
When loads rise, the instinct is often to add more cooling capacity. But without accessories that properly control the airflow path, that extra capacity is largely wasted.
Simple, often deliver the fastest ROI in airflow management. Multiplied across dozens or hundreds of cabinets, the energy savings are substantial.
Practical accessories that deliver immediate results:
- : These block airflow through open rack-mount spaces, keeping hot air at the back of the cabinet.
- : This blocks airflow around the sides and top of the equipment mounting space, ensuring cold air passes directly through equipment while preventing hot air from recirculating.
- These cover cable openings in the equipment mounting rails to block airflow around equipment.
- These allow network, power, or cooling cables to pass through the side of the cabinet while minimizing bypass airflow.
Chatsworth Products’ can be pre-configured with a variety of standard thermal management accessories to ensure airflow optimization from day one.
2. Ensure Your Hot/Cold Aisles Are Fully Contained
Containment is one of the most impactful ways to improve cooling efficiency—but many operators assume containment requires tearing down existing infrastructure or investing in large-scale construction. Others see it as an “all-or-nothing” strategy that only applies to brand-new builds.
The reality is that containment can be incremental, retrofit-friendly, and highly adaptable to different environments. From cabinet-level to row and aisle level - modern containment solutions can be added without disrupting operations—unlocking stranded capacity and improving efficiency right away.
Scalable containment options include:
- (Cabinet Level): Capture hot exhaust at the source and channel it into the overhead plenum—ideal when full aisle containment isn’t feasible.
- (Cabinet/Row Level): Telescoping panels that install quickly with no on-site fabrication—perfect for fast, incremental upgrades.
- Aisle Level): Flexible, field-fabricated systems that can be installed over existing cabinets—even in irregular spaces with obstacles.
3. Choose Cabinet Colors Wisely
When planning a cooling strategy, most operators don’t think twice about cabinet color. It feels like a design preference, not a technical decision. But in practice, finish has a direct impact on efficiency and usability.
Switching to is a simple move with a surprising impact:
- 70% More Reflective: White finishes, like CPI’s Glacier White, reflect more light, brightening aisles without additional fixtures.
- Lower Energy Demand: Reduced lighting needs also lower cooling loads.
- Operational Gains: Improved visibility helps technicians work up to 20% faster, with fewer errors—a critical factor in uptime-focused environments.
Across an entire facility, these improvements compound into significant cost savings and operational efficiency.
