  • Heat exchanger air leakage of just 0.1% - one-tenth that of heat wheels
  • Integrated controls with advanced communications and algorithms for self-healing protective routines and multi-unit teamwork efficiency
  • Quick restart options in event of a power outage
  • Low maintenance design and operation
  • Single footprint
  • Optional DX trim for additional capacity

Benefits

Saves You Money

  • World’s most energy efficient heat exchanger, with an operational PUE as low as 1.03
  • Maximum annual hours of dry and wet economization per year, while minimizing annual water usage
  • Low peak power to allow downsizing of backup generator capacity or make more IT power available for sale
  • Increased productivity through advanced controls and monitoring
  • Lowest operating costs for higher profitabilityLowers Your Risks
  • Multiple EC fans and DX circuits to ride through individual component failure
  • Recover unit cooling capacity quickly during power events
  • Rapidly scalable for faster deployment and time to market
  • Ensures complete separation of air streams preventing any contamination and humidity infiltration Makes Management Easier
  • Advanced controls that leverage unit and system monitoring intelligence
  • Built-in routines for optimizing operations based on the cost of water and cost of energy for the most cost-effective performance.
  • Controls algorithms automatically manage unit lead/lag, protect against coil freeze, manage compressor utilization, maximize economization and perform other business-critical functions
  • Reduced maintenance burden through automated economization and having fewer moving parts than other technologies such as heat wheels
