New York City Approves the Polar Cap 2 Retractable Roof
In a Buildings Bulletin dated October 19, 2016, NYC Buildings Department establishes acceptance criteria for retractable-type horizontal cold aisle containment systems installed in information technology equipment areas.
The installation of a retractable-type horizontal cold aisle containment system installed in information technology equipment areas (horizontal cold aisle containment system) is used to minimize the consumption of energy by providing an overhead thermal containment barrier used to create a cold aisle. However, the overhead containment barrier may obstruct the performance of code-required fire suppression systems (BC Chapter 9). This bulletin establishes acceptance criteria for horizontal cold aisle containment compliance with the NYC Construction Codes.
The Subzero Polar Cap 2 is a fully electric roof system that retracts into a metal housing when the fire suppression system is alarmed. Having a pre-action system that reacts to a smoke detector will ensure that the containment roof is fully retracted long before the fire suppression system is discharged. Additionally, the roof material meets the stringent flame and smoke requirements of ASTM E-84 Class A Rating. The Polar Cap 2 can also be manually opened and closed when maintenance is required above the containment space.
This game changing roof system ensures that the containment roof obstruction is fully removed electronically when a smoke detector is alarmed. Additional benefits include the ability to wirelessly open the roof for maintenance above the containment, modular design allowing for increase or decrease of size, ease of deployment, and the sleek look of the roof is easy on the eyes. This is the ultimate containment roof system.
Polar Cap Retractable Roof Available Fall of 2014!
The patented Subzero Engineering Polar Cap is the first fully NFPA compliant containment roof system that attaches to the top of the racks and forms a ceiling that prevents hot and cold air from mixing.
Most data center containment systems rely on the heat generated from a fire related incident to release the containment system, as it can pose an obstacle to the fire suppression agent. The NFPA has determined that it is important to have a faster response time and more importantly, a testable system.
The updated Subzero Polar Cap retractable roof system is now a fully electric roof system that retracts into a metal housing when the fire suppression system is alarmed. Having a pre-action system that reacts to a smoke detector will ensure that the containment roof is fully retracted long before the fire suppression system is discharged. Additionally, the roof material is made with the highest fire resistant standard of ASTM E-84 Class A rating.
The Polar Cap can also be opened and closed when maintenance is required above the containment space.
The new roof system is fully customizable in both length (up to 30’) and width (up to 5’). The aluminum profile is less than 6” high and thus it presents no problem with obstructions above the cabinets.
