Standard Contained Aisle System

Jellemzők

One of the potential drawbacks with the open Hot/Cold aisle arrangement is the risk of hot air recirculation and hot-spots. With CONTEG Contained Cold Aisle (CCA) or Contained Hot Aisle (CHA) solution, the containment system is used to physically separate cooled air from hot exhaust by forming a cold plenum space and preventing mixing of hot and cold air, thereby eliminating hot-spots. The cold air is supplied into the contained aisle through perforated tiles from the raised floor or produced locally by CoolTeg units which are installed directly in the row of cabinets as an integral part of the aisle. Standard width of CCA/CHA is 1.2m (two perforated tiles) or 1.8m (three perforated tiles) and containment can be deployed with standard swing doors or dual leaf sliding doors. To use Contained Cold Aisle is highly recommended to maximize cooling efficiency and minimize energy consumption of the entire Datacenter.

Doors sections

There are two door solutions – sliding or swing (with hinges) doors. Both types consist of two door wings.

Standard sliding doors are equipped with mechanical opening system (each door wing is independent) and can be equipped by Dual-Synchro system (both door wings moving simultaneously) or automatic system with electronic control.

Standard swing doors are mechanical and they can be equipped with Automatic Door Handle (ADH) system. Using the Automatic Door Handle the Contained Cold Aisle doors can be controlled and opened/closed either locally via push buttons or integrated with your access control system.  The ADH can also be integrated with RAMOS to provide alarms and further increase the flexibility of the system.

A blank panel could be used instead of doors to close one end of contained aisle.

Roof

The roof sections are bolted onto the top of racks to prevent mixing of cooled air and warm exhaust. The frame is made from 1.5mm powder coated steel and is available in 600, 800, 900 & 1100mm widths to suit all deployment options. The vertical sections feature a glass insert panel to allow easy access to the top of installed racks whilst allowing maximum light into the cold aisle. The roof panel is made from 6mm clear polycarbonate to allow easy integration of fire suppression systems into the cold aisle.

Solution available for 42, 45 and 48U racks and for 1000, 1200, 1800 and 2400mm width of the aisle.
