Enhancing Data Center Resilience with TES & EcoCAT™ SCR Technology
(White Paper Summary)
Modern data centers face growing challenges: higher power densities, stricter environmental regulations, and zero-tolerance for downtime. R.F. MacDonald Co. helps address these needs through two complementary technologies:
- Thermal Energy Storage (TES) for instant emergency cooling
- EcoCAT™ SCR systems for clean, compliant emergency generator operation
Together, these systems deliver unmatched thermal resilience, emissions compliance, and energy savings.
1. The Importance of Emergency Cooling
Even a short cooling interruption can cause equipment failure, data loss, and significant downtime costs. Cooling is at risk from:
- Power outages
- Chiller or pump failures
- Environmental events (wildfire, heat waves, seismic events)
- Operational or maintenance errors
TES provides an immediate buffer of cooling capacity when mechanical systems or power fail—supporting continuous operation until backup systems stabilize.
2. How Thermal Energy Storage (TES) Works
TES systems store cooling energy (chilled water or ice) during low-demand periods and release it when needed—especially during outages, transitions to generator power, or peak-load reductions.
TES Types
- Chilled Water Tanks – Delivers immediate cooling during outages
- Stratified Tanks – Optimize thermal layering and system efficiency
- Ice Storage Systems – High-density, long-duration cooling
TES Benefits
- Instant cooling during emergencies
- Lower peak utility costs
- Enhances renewable energy integration
- Reduces load on emergency generators
- Supports CA & NV energy resiliency goals
R.F. MacDonald integrates TES with leading pump and chiller systems from Camus, Cleaver-Brooks, and Taco for new and retrofit installations.
3. EcoCAT™ SCR Technology: Clean Emergency Generator Operation
When generators power the data center during outages, emissions spike. EcoCAT™ SCR systems reduce NOₓ emissions by up to 95%, meeting strict CARB and local AQMD standards.
How EcoCAT Works
- Injects a urea/ammonia reagent into generator exhaust
- Converts NOₓ into harmless nitrogen + water vapor
- Automatically adjusts dosing based on generator load and temperature
System Features
- Modular designs for 200 kW–3 MW generators
- Integrated controls and monitoring
- Custom housings for site-specific configurations
- Field service and regulatory support
EcoCAT Benefits
- Meets Tier 4 Final NOₓ requirements
- Allows extended generator run times
- Reduces visible emissions and community impact
- Improves ESG performance
4. TES + EcoCAT: A Unified Resilience Strategy
| Function | Technology | Outcome |
|---|---|---|
| Emergency Cooling | TES | Maintains temperature through failures & transitions |
| Clean Power | EcoCAT SCR | Reduces NOₓ emissions during generator operation |
| Seamless Integration | Combined Controls | Coordinates cooling + backup power |
| Sustainability | Dual Approach | Lower emissions + lower energy cost |
This integrated approach provides full thermal + electrical resilience for modern data centers.
5. Design & Implementation Considerations
- Correct TES tank sizing for IT load and backup runtimes
- Redundant heat exchangers and pumps for reliability
- Above-ground and below-grade tank options
- SCR control integration with the generator PLC and BMS systems
- Maintenance programs for catalysts, pumps, and sensors
6. R.F. MacDonald Co. Capabilities
- Full engineering, design, and installation of TES and SCR systems
- Integration with chillers, boilers, pumps, and generators
- Emissions testing & compliance support
- 24/7 service and maintenance programs
- OEM partnerships with Camus, Cleaver-Brooks, Taco, and others
In Conclusion
As data centers expand and reliability expectations rise, TES and EcoCAT™ SCR technology deliver the cooling continuity and clean backup power needed to stay online—no matter the event.
R.F. MacDonald Co. provides the engineering expertise, field support, and regulatory knowledge to help operators build resilient, efficient, and sustainable data center infrastructure.
