One key part of bestTate has partnered with Upsite Technologies the makers ofpractice design for raised floor data centers includes theKOLDLOK to bring you the most advanced wire & cableelimination of bypass air. Bypass air is any air delivered into thepenetration air sealing grommet available. This partnership wasdata center that is not consumed by the equipment andforged from the common understanding that the raised floorexhausted as waste heat. Common practices to reduce bypassdesign is the most cost-effective and flexible way to future proofair include the use of containment systems, blanking panels,a data center. With raised floors a data center can handle largeangular or directional air delivery, and air sealing grommets for allvolumes of wires, cables and other services, while efficientlywire and cable penetrations in the floor.cooling the heat loads of modern and next generation designs.Advantages of a Raised Floor Easily adapt to technological and client changes over the datacenter’s life-cycle at low cost. Reduced operating costs and lower facility and maintenancecosts through accessible, flexible, and adaptable services. Offers the best overall solution for distributing water and otherliquid cooling agents to row and rack based equipment. Underfloor service distribution space keeps the interior spaceclean and neat for proper air migration in-and-out of equipment. Water distribution lines placed under a raised floor pose lessthreat in the event of water leaks or condensation due tosystem failure. Raised floors provide the platform for future scalability. Ability to accommodate a range of cooling solutions whileincreasing efficiency and heat load capacities. Provides the ability to separate water, power and cable. Flexibility to incorporate the most energy efficient designopportunities for cooling data centers. Ability to terminate cables wherever you need them withcomplete flexibility, accessibility, and unlimited capacity.3
