8 kW Cooling options make the most of the core elements included in each Great Lakes ES Series Enclosure

A Medium (8 KW) cooling solution can also be easily implemented

The Ultimate Cooling Enclosure - No Refrigerants, Liquids, or Modifications Required-

Thermal patented technology makes the Great Lakes Lake Effect Enclosure your solution for all your networking needs. This Enclosure eliminates the use of refrigerants or coolants in your data center environment. The use of vanaxial fans originally designed for the aerospace industry allows this enclosure to create a usable air environment which can satisfy up to a 10KW of computer load. A consistent 65 degree temperature in the front plenum chamber is maintained from top to bottom, there by protecting your equipment from hardware failure due to overheating.  It contains a 44 RMU rack space, and all the same features as our Great Lakes Enhanced Series Enclosures.


What's special about these thermal enclosures?

  • Lake Effect base unit with two (2) pair of power coated 19” universal M6 rails and M6 hardware, shipping pallet, and two (2) sets of power strip brackets
  • Plexiglas front door and mesh rear door

In order to increase the cooling effect within the enclosure, the goal remains to direct conditioned air and to restrict the possibility of hot air recirculation. At the same time, any proposed solution must also allow for any desired cable management in the front of an enclosure.

The use of the Great Lakes Brush Grommet Kit, designed to mount to the proprietary Flexible Mounting Profile* found in each Great Lakes rail, helps to prevent bypass air flow and to keep conditioned air in the front of the enclosure. While brush grommet prevents hot air recirculation and prevents conditioned air from passing by the equipment mounted within the enclosure, it still allows for any desired cable management within the enclosure.

A Medium Cooling solution could also include optional fans in the front mesh door in order to accelerate the intake of conditioned air into the front of the cabinet, as well as its movement through the equipment mounted within. The employment of split fan rear doors can assist in the removal of hot air from the enclosure. This solution can be further enhanced by the installation of an optional fixed/adjustable ducted chimney to channel the natural upward movement of hot air, removing it from the enclosure through an upper rear opening to which the chimney may be attached. Heat removal may be further activated by the addition of an exhaust fan, to be mounted within the chimney.

This Medium Cooling Solution is targeted at the delivery of 8 kW through the use of some simple enclosure options and accessories. Actual cooling shall be based on the options, accessories and techniques employed, as well as the conditions and efficiency of the computer room air conditioning system employed in the data center.

*The Flexible Mounting Profile (FMP) is a series of holes along each rail, installed at one-RMU increments, and located outside the standard pattern for all EIA rail-mounted equipment. From copper bus bars to cable rings, cable managment posts and other accessories, the design and manufacture of Great Lakes rails is so strong that virtually nothing mounted to the FMP will take away from the dimensional stability of the rail itself.

The rails in Great Lakes’ ES series enclosure are #12 gauge steel, formed three times for
added strength. An ES enclosure can support more than 2,000 pounds of mounted equipment.

The water cooled data cabinet or water cooled rack in a data center or equipment closet is now being classified as the most efficient means of transferring heat away from expensive equipment that may cost tens of thousands to replace if damaged. American Tech Supply as a leading rack supplier now carries a complete line of water cooled data cabinets and water cooled racks and carries the revolutionary water cooled data rack from Knurr and Emerson Network power for the ultimate in cooling and thermal temperature management for data cabinets and data centers with high temeperature requirements. The advantages of the simple and safe water cooled data cabinet and water cooled rack previously outweigh the disadvantage of the low heat transfer potential of gaseous coolants. In the meantime, the heat load in high-performance servers has exceeded the options of cost-effective cooling with air. The CoolTherm® range of 'water-cooled server cabinets or water cooled data cabinets' can provide a great advance in data cabinet thermal management, reducing computer room costs, while improving operational performance and reducing facility operating costs. Typical, high quantity conventional server cabinet layouts can effectively dissipate around 3.6kW each.


Knürr CoolTherm® water cooled racks and water cooled data cabinets are completely sealed off from the room air. The dissipation of the total power loss is made via an air-to-water heat exchanger in the base area or door of the rack, which is connected to the cold water system in the building. Redundant high-performance fans drive a closed cold air circulation in the rack’s interior. The built-in servers are supplied from the front with air that is brought to the right temperature of about 20–25°C (68 °F to 77 °F). The warmed air is collected at the rear topside in the rack, pushed down by the heat exchanger and back to the front, to the server front panels. There are no requirements for room thermal management; the rack system is fully independent from the room air. Knürr AG with its global front position in thermal management research and development once again sets the high technology standard. The company consequently already provides a water-cooled server rack in series production today – the Miracel CoolTherm. This highly efficient system does not divert any heat loads to the surrounding environment. Instead, the entire energy is routed via the cold water system of the building infrastructure. The computer units in the server rack are supplied with cooled air from the heat exchanger. Trade standard servers can consequently be used and simultaneously combine the advantages of water cooling with low space requirements and high heat transport. With the optimised heat exchanger and air guidance systems, the CoolTherm attains up to 20,000 watts cooling power.

A single CoolTherm® 19" data cabinet or data rack will manage a 22kW heat load, enabling an 80% reduction in present, typical conventional cabinet numbers within large data centers. Resultant floor space savings of significantly reduce the take-up of large areas of expensive computer room floor, as server power levels skyrocket.
Cabinet installation costs can also be halved and enormous year-on-year operational savings made in associated reductions in CRAC install and running costs.
