Great Lakes Water Cooled Data Cabinets- Great Lakes Water Cooled Data Racks- 8kW Cooled cabinets, 4kw Cooled Cabinets,

Welcome to Data Center Power and Data Cabinet Cooling for the Future

Great Lakes Water Cooled Cabinets-Great Lakes Closed Loop Data Cabinets

This after-market product uses liquid cooling technology to provide a solution without the use of any fans. Coolcentric™ recently approached Great Lakes Case & Cabinet Co., Inc. expressing a desire to be able to offer a “Great Lakes” solution as part of its product portfolio. Great Lakes has worked with Coolcentric™ and today, the Coolcentric™ RD18WXS-07 includes a rear door heat exchanger and an adapter frame
which is designed to fit the Great Lakes GL840ES-3042 enclosure. If a chilled water supply is readily available, the LiquiCool door can be easily installed on a “working” enclosure already deployed as an “on-site upgrade”.

With no fans or moving parts and weighing only 60 pounds, this solution adds only 5.6 inches to the depth of the GL840ES-3042 enclosure. The Coolcentric™ LiquiCool door holds 1.5 gallons of cooled water and without major adjustment to existing cabinet deployment, it allows for an easy addition to offset the heat generated by a high density environment. Quick-connect couplings allow for fast and easy installation.

If a CDU is required, the Coolcentric™ Coolant Distribution Unit can support 10-12 LiquiCool doors.

The Coolcentric™ solution offers a maximum cooling performance of 30 kW with nominal load estimated at 20 kW and redundant cooling at 15 kW

1. Chilled water passes through a coolant distribution unit (CDU) and enters the heat exchanger.
2. Conditioned air at consistent pressure is directed through a plenum chamber.
3. Conditioned air passes through rack mounted equipment.
4. Quiet (65 dB) high efficiency variable speed exhaust fans remove hot air.
5. Hot air passes across the heat exchanger.
6. Water then leaves the heat exchanger coil to begin a return trip to the chiller.

This enclosure design is specifically designed to provide maximum, state-of-the-art data center cooling. Great Lakes offers a fully-configured enclosure (CLWCE) or a kit to convert any 42" or deeper ES Series enclosure from an air cooled unit to a water-based, liquid cooled unit. This allows the data center manager ultimate flexibility to upgrade to high density at any time.

The CLWCE is a 38 rack mount unit, 19" EIA enclosure with an integrated closed loop cooling system. The CLWCE cooling system uses low pressure chilled water to remove the heat generated by the servers.

The CLWCE/kit includes:
An 8 RMU heat exchanger, developed in conjunction with Lytron Inc., an American company with over 50 years of experience in developing liquid cooling systems. A custom control unit to manage and monitor the system 2 doors, fans in the rear door and a plenum in the front door.

Maximizing “up time” and fault tolerance has been considered in all aspects of this liquid cooling system:
•The cabinet contains N+1 fans.
•A fan can be replaced while the system is running.
•If the temperature in the cabinet exceeds a user-defined threshold, the doors will automatically open, the fans will shut down, an alarm will be sent, and the system will use room air to cool until the problem is resolved.
• Using a Coolant Distribution Unit (CDU) with redundant pumps will ensure the coolant is delivered at a consistent temperature and consistent flow rate.
• The CDU is typically set to a temperature above the dew point so the risk of condensation is eliminated.
• A liquid manifold is available.
• The enclosure (and Lytron’s CDU) can accommodate redundant power sources and have leak detection systems.

Cool air is delivered to the front of the cabinet. This air flows through the servers picking up heat, using the same concept as an open air cooled cabinet. However instead of flowing out the back of the enclosure into the hot aisle, three fans located in the backdoor direct the hot air down to the bottom of the cabinet where it passes through a heat exchanger. In the heat exchanger, heat is transferred from the air to the coolant flowing through the heat exchanger. The temperature of air exiting the heat exchanger has been reduced and the air is now ready to begin the path again.

A typical liquid cooling configuration would be a cluster of five enclosures, supported by a single CDU, such as Lytron’s LCS50. Lytron™ offers proprietary, interactive software which can help determine your data center’s liquid cooling needs.

When working within a defined space which can not be structurally altered, containment becomes a viable avenue to the future growth of a mature data center.

One of the most challenging aspects of emerging technology is the inability to predict how that technology will grow, evolve and adapt to meet changing data center conditions. Many of today’s data centers are facing tremendous challenges in power and cooling which can not be met simply by expanding the current infrastructure or simply adding additional CRAC units.

Today’s data center manager must often find new ways to grow the facility in its existing “footprint,” adding server density within existing enclosures, while using a “containment” strategy to capture as much conditioned air as possible or to isolate and exhaust as much hot air as possible within the data center space.

Great Lakes has taken two approaches in support of this need.

The first is the development of products which can close off the aisle via sliding or hinged doors, which attach easily to the existing enclosures. Our engineers will listen to your needs and will develop an economical approach to meet them, providing a highly affordable and yet custom solution.

For those situations which require the installation of containment curtains mounted above the enclosures themselves, we have developed a strategic alliance with Polargy, Inc., for the installation of the company’s line of Polar Plex™ containment systems which consist of structural aluminum framing and either vinyl curtains or thermoplastic panels, to create the desired environmental conditions.

The goal of Future-Proofing via the Great Lakes ES Series enclosure is very easy; however, to have the best opportunities to easily "upgrade" the enclosure, you do have to include some prior planning.

We have designed the air manager, the Lake Effect blower and the CLWC heat exchanger to occupy the bottom area of the enclsoure. If the cabinet is to progress from low to high density in its lifetime, we suggest that you use filler panels to block the bottom 8 RMU of the enclosure. In this approach, the cooling options available may be easily employed and upgraded without ever taking the enclosure out of service!

As the arises, you can improve the cooling and exhaust capabilities of the ES from the air manager and chimney, all from a single enclosure platform! It's simple and it's rocket science, both at the same time. We're talking about one enclosure platform with a lifespan beyond that of the data center itself!

Shown is a cluster of twenty GL840ES-2442 enclosures with adjustable chimneys to accomodate
varying ceiling heights in this section of teh data center space. These enclosures are located in the
H5 Colocation Center in Dallas, Texas. the H5 Colocation Center is a purpose-built facility
for data center/colocation, disaster recovery, and flexible lab/office space.

Whether you need 20 enclosures for your existing space, or 2,000 enclsoures for a new data center, Great Lakes Case & Cabinet Co., Inc. has the expertise, experience and world class customer service to meet your needs, on-time and on-budget.

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.
