Great Lakes ES Series Lake Effect™ Enclosure

Eliminate Server and Equipment Failure Due to Overheating

Low Price Guarantee


What's special about this server enclosure?

  • Combines the versatility and durability of an ES-Series enclosure with the ultimate cooling power of the Lake Effect™ air circulation system to provide up to 10 KW of heat dissipation for high-density server applications
  • Harnesses and then uses the coldest air above the raised floor to cool equipment, instead of using harmful refrigerants, chilled water, or any other liquids that could cause catastrophic and irreversible damage to servers in the event of contact
  • Eliminates temperature gradients throughout the enclosure by providing a consistent flow of cool air to the front intake fans of  the servers, while pushing the used hot air out of the enclosure's rear mesh door to prevent recirculation

Overheating and poor air circulation are the main causes of equipment failure inside rack mount enclosures. Many companies utilize specialized air conditioners or water-cooled systems to cool hardworking server equipment, but these methods can be very expensive and just as dangerous if failure or leakage ever occurs. The Lake Effect™ Enclosure from Great Lakes offers the ideal solution for preventing server failure, without the aid of refrigerants or liquids. This enclosure utilizes highly sophisticated, high-performance vanaxial fans (originally designed for the aerospace industry) to provide up to 1224 CFM of directional airflow to the front of servers, helping equipment to stay continuously cool and functional.
