Contained Hot Aisle

Contained Hot Aisle

In cases where there is no raised floor for cold air delivery or the room dimensions do not support the contained cold aisle deployment, the best solution is to use the Conteg Contained Hot Aisle (CHA) together with CoolTeg units.

Contained hot aisle

With Conteg Contained Hot Aisle (CHA) solution, the containment system is used to physically separate cooled air from hot exhaust by forming a hot plenum space and preventing the mixing of hot and cold air, thereby eliminating hot-spots. Racks are aligned back to back and hot air is collected inside of the containment at the rear of the row of cabinets and is led into the CoolTeg units which are positioned directly in the row of cabinets as an integral part of the aisle. The cold air is blown out of the CoolTeg units and delivered directly to the front of the active IT equipment. Standard width of CHA is 1m, it can also be 1.2 m or 0.8 m wide and containment can be deployed with standard swing doors or dual leaf sliding doors. To use Contained Hot Aisle is highly recommended to maximize the cooling efficiency and minimize the energy consumption of the entire Datacenter.

    The width of the closed cold aisle is 0.8, 1.0 or 1.2 meter.

    The height of the enclosed hot aisle is designed for CONTEG racks 42, 45 and 48U

    Roof sections: Available lengths include 400, 600, 800, 900 and 1100mm. The roof panels are made of clear polycarbonate to ensure sufficient light penetration into the closed aisle. This polycarbonate meets the fire-resistance and flame retardation requirements according to standards appropriate to the locality. The roof panels support the possibility of bringing the fire suppression agents into the space of the closed aisle.

    Side panels with glass view-through

    Entrance to the aisle is ensured at least by one single-wing (for aisle widths 0.8 and 1 m) or double-wing   (for width 1.2 m) sliding or standard door (door opening angle 180°), height 2246 mm. The other end can use a door frame of the same size and a blanking panel - in this case the corridor is not passable. In case of a passable aisle it shall be equipped with single or double-wing doors on both ends. The doors can be equipped with manual or hydraulic door closing system or with an automatic door control system, environmental monitoring and fire alarm system, to ensure that the door is opened or closed automatically when needed.
