The Solution

The Karis Technologies Thermal Management is the only product available that meets all the challenges of cooling high density IT equipment presented above.

1 – Effectively Provide Constant Temperature Air Throughout the Rack, Bottom to Top

To solve the problem one must understand that the computer supply fans are not strong enough to pull air from the cold aisle through mesh doors to cool higher density enclosures. The cabinet must create a Usable Air Environment. That is, the right temperature at the right volume at the right velocity at the right pressure delivered at the air intakes of the servers. The patented air delivery system, delivers air through a pressurized plenum directly to the air intakes of servers. Utilizing a pressured plenum allows for control of the large quantity of air being delivered. Without that control, the lower servers in the rack would be starved for air. Further, the enclosure’s air intake location assures the air delivered to the servers comes from the coolest air in the room (near the floor). The air delivered is a constant temperature since there is no additional mixing with ambient room air; the solid acrylic cabinet door panel prevents this (and provides additional security over open mesh front door designs). Tests confirm that the top server in the rack is cooled with the same temperature air as the lowest server. The temperature of the air delivered is from above the floor reducing risk of condensation from the approximately 55 degree F air below the floor.

2 – Work Within Existing Data Center Constraints So As Not To Cause Disruption To Existing IT Equipment

The Thermal Management Enclosure requires no infrastructure changes to implement. There is no additional piping, duct work or floor modifications as some high density cabinet systems require. Static pressure of under floor air systems is not reduced by new openings in the floor. No additional water or refrigerants are introduced to the data processing environment, thereby reducing risks of leaks from these systems. It can be placed on an existing data center floor, configured with servers and be operational immediately.

3 – Maximize Use Of Existing Air Conditioning Infrastructure

Cooling air directed to the equipment intakes via the pressurized plenum prevents bypass air flow, maximizes heat transfer and returns the highest temperature air to the CRAC units allowing them to operate at design capacity. The Karis Thermal Management Enclosure does not add additional air conditioning capacity with its associated high capital and operating costs but makes efficient use of A/C unit capacity, whether in an existing or new facility.

4 – Eliminate Air Flow Restrictions Within the Cabinet

Air is delivered where it is required as the IT equipment manufacturer’s intended. There is no blockage of the air associated with under cabinet cut outs. Air is taken from the cold aisle and delivered directly to the equipment air intakes of individual racked components. The Thermal Management Enclosure also allows users to effectively manage cabling. Standard features include easily accessible vertical wiring troughs for inter-cabinet connections plus side panel knockouts for cabinet to cabinet connections with brush style air restrictors further reducing cooling air leakage to where it is not needed and inefficiently wasted. With no cabling blocking air flow from equipment exhaust, it operates cooler and reduces failure rates.

5 – Be of High Quality but Affordable and Simple To Implement For All Levels of Users of IT Equipment

Our latest innovation of the Thermal Management Enclosure adds to our long line of computer enclosure advancements in cable management, numbered rails for “U” identification, integral ground lugs, welded 1 gauge steel enclosure with the ability to support 2000 lbs of rack equipment. The Thermal Management Enclosure uses high quality long life fans. Air flow adjustment does not depend on complex and expensive variable frequency drives. It is simply the most effective and best value solution to implementing high density computer equipment loads in existing or new data center applications. It requires no infrastructure additions/modifications. The Thermal Management Enclosure can reduce operating costs by less equipment failures and improved performance of data room air conditioning systems. The simplicity built in allows Karis Technologies to compete very favorably with other high density solutions on cabinet cosy alone even discounting the infrastructure modifications required by other manufacturers’ enclosures and systems.
