Data Center Cooling - Armstrong | Korea

Achieve more effective, dependable cooling and precise control of relative humidity with EvaPack™ from Armstrong International.

Boost your efficiency and lower your PUE with EvaPack™, Armstrong’s best-in-class data center cooling and humidification solution. Our dependable, low-maintenance evaporative pad humidifier ensures effective cooling and precise control of relative humidity in your data center, while reducing energy use for substantial cost savings.

EvaPack™ is Simple, Smart and Adaptable

  • Installation is quick and easy
  • Works with various types of water, including: potable, reverse osmosis or soft
  • Compact design has a maximum footprint of 236.2 in [600 mm]
  • 23.6 in [60 cm] depth including droplet separator
  • No absorption distance
  • Water connections are on the side
  • Draining and overflow connections: 1.5 in [40 mm]

Energy Savings and Efficiency

  • Designed to maximize efficiency and minimize pressure drop.

Example: For a 294,288.8 CFM [500 000 m3/h] airflow, a pressure drop difference of 0.2”WC [50 Pa] represents a saving of 67,500 kWh per year ($7,630.88 [6,750€]/year at $.01 [0,01€]/kWh).

  • EvaPack™ uses heat present in the air for humidifying and cooling, resulting in lower energy consumption
  • Optimized to provide the highest air/water contact surface—up to 12% more than traditional evaporative pads

The Optimized Water Contact Surface Helps Achieve a Low PUE

Designed for Flexibility and Customization

  • Size and configuration can be tailored for your requirements
  • Available for AHU, duct, fan wall, direct or recirculated water applications
  • From approximately 3.8 ft2 to 96.8 ft2 [0.36 mÇ to 9.00 mÇ] in one piece assembly. 
  • Low-maintenance, Easy to Clean and Service
  • Cassettes are accessible from the side, or from the front for larger sizes, which reduces the requested replacement space. Cassette maintenance can be finished within seconds.
  • Water pump, water level detector, and manual gate valves are accessible on the service side for simplified maintenance. Elements are easy to disassemble, clean, and reassemble.

Safe, Hygienic and Efficient

  • No glue or hazardous substances
  • No fiber loss
  • Encrusted silver ions prevent bacterial proliferation
  • Fireproof
  • High moisture absorptive capability
  • Minimum pressure drop

Precise Control and Water Savings

In direct water configuration with a reverse osmosis (RO) water supply, EvaPack™, used in conjunction with Armstrong’s wide rangeability water valves, allows proportional control of humidification by injecting the exact quantity of water needed for the cooling process—with no wastewater.
