EVERCOOL Cooling Solution for Mission Critical Projects


A solution for rapid deployment in mission-critical cooling applications, Design Envelope EVERCOOL offers pre-engineered, feature-rich options that can be configured on-site. The platform meets the stringent requirements of the Uptime Institute for Tier III data centers while avoiding the traditional requirements of extensive site programming and customization. EVERCOOL reduces site commissioning time by up to 30% and reduces overall energy consumption, coordinating cooling system operation to reduce energy costs by as much as 40%.


EVERCOOL uses an innovative design with internal redundancy and a hot-standby controller for continuous uptime. This design approach ensures seamless transfer (in less than 200 milliseconds) between controllers in the event of a failure.


  • Eliminates the need for on-site programming
  • Proven sequence of operation reduces site commissioning time
  • Built-in redundancy eliminates the need for additional wiring and the installation of relays
  • Demand-based control
  • Feedforward optimization
  • Patented Parallel Control optimization
  • Energy and water usage are reduced by optimizing the operation of the entire cooling plant
  • Enables Condition-Based Maintenance
  • CBM approach is documented to save 25% of the equipment life cycle cost
  • Improves equipment life span
  • Applications: Air-cooled or water-cooled chilled water system automation for data centers
  • Description: The Armstrong Design Envelope EVERCOOL system is an integrated automation and optimization solution for data center chiller plants. Designed to meet the Uptime Institute requirements for all Tiers of data centers, this mission-critical platform has also been standardized for speed to market and quick deployment.
  • Configuration: Integrates with all brands of chillers, pumps, and automation systems. Installs directly with chiller plant equipment. If preferred, the EVERCOOL connects with any data center information management (DCIM) system or central building automation system (BAS).
  • Performance range: Standardized solution controls up to six chillers, six cooling towers, six chilled water pumps, six condenser water pumps (when applicable), and redundant sensors and valves. Project-specific requirements may include free-cooling, water-side economizer, chilled water storage tanks, etc. No limitations in plant size and cooling capacity.
