Today’s faster and increasingly powerful computing hardware generates significant heat. Heat can cause rapid failure of essential components. To resolve that issue, data centers rely on cooling the environment. Unfortunately, cooling data centers can be very expensive. Therefore, reducing cooling costs has become a major concern for data center managers and have created a demand for products providing improved performance and cost-efficiency. 

In the past, many centers relied on the use of wall and floor foam compounds used around cables to prevent the escape of cool air. Recently, data center managers have determined that such foams do not effectively prevent cool air from escaping. Roxtec sealing systems are a solution to that problem.


Roxtec’s cable entry sealing system for walls and floor is more than a firestop— it prevents cool air from escaping. Plus, it provides a dust and moisture tight seal. Roxtec frames can be cast, welded and bolted onto the structure to create a clean pass through for the cables. Round sealing solutions are also available for cables running through core drilled holes and conduit. One of the biggest benefit of Roxtec’s sealing systems—- they are re-enterable—data center managers can easily add future capacity.

Roxtec also has designed a simple cable sealing system called EZEntry™.  EZEntry™ enables users to route and seal around multiple pre-terminated cables into data center cabinets of different sizes in one single frame opening.

EZEntry™ is constructed of a lightweight composite material and is a single-sided application for easier installations. It is delivered as a complete kit-solution, including a lightweight non-metallic frame, an integrated compression unit and adaptable sealing modules for cables of different dimensions. In addition, EZEntry™ is certified for IP 66/67, UL/NEMA 4, 4x, 12, 13 protection. EZEntry™ is a great solution for managing cable and for keeping dust and moisture out of your equipment.

In addition, engineers can reduce overall cabinet size through Roxtec’s compact design and save major labor costs by eliminating the need to cut and re-attach connectors.  This design also allows for cost-effective maintenance and future expansion with easy re-entry into the system.  Data Center designers can avoid the liabilities of product and systems’ failure and will have fewer warranty claims.
