Data Centre – cold / hot aisle containment

In the era of globalised business process information, appropriate protection against business and operating risks is vital to secure company’s uninterrupted operation. Unlimited and complete 24/7/365 access to information is currently becoming one of the most valuable business resource.
In many cases, data stored in corporate data centres represent the most precious assets of the enterprise. Hence, important data require a suitable level of protection and security. A server room with adequate power systems, cooling systems, access control and detection of various types of threats ensures comfort and safety of operation and the right level of corporate data security.

Increasing capacities of data centers generate demand for efficient energy performance in HVAC systems. The greatest challenge in designing data centers is to ensure an optimum operating temperature of IT equipment located in server cabinets along with protection against thermal damage.
The correct temperature in a server room can be achieved by preventing cooling air from mixing with hot air generated by the active equipment running in server cabinets. An easy and efficient remedy to such problems is placing cabinet rows parallel to one another. Opposite cabinets should face one another. Cold air is delivered via the access floor and blown directly in front of server cabinets to create the so-called “cold air zone”.

 In order to ensure proper air circulation inside the cabinet, the front and rear doors should be provided with perforation with clearance of 80%, as well as with additional accessories that prevent air from being dissipated within the cabinet i.e.: blanking plates, vertical masking panels, horizontal brush strips.

Slide door system for Data Box aisle.

A Data Box can be accessed through a double-wing sliding door. Mounted on one or both sides of the Data Box aisle, they ensure safety and physical separation of cold/hot air flows. Slide door is available in three versions: without lock, with single-point lock, and with single-point lock + electronic access control. The door is fitted with glass panes for improved control over Data Box interior events.
Material – Sheet steel powder painted, mineral safety glass.

Data Box aisle panel

Aisle panel can be mounted on the end of Data Box aisle instead sliding door.
Material: Sheet steel powder painted, mineral safety glass.

Data Box aisle roof

Available in modular design. Roof modules are available in four widths, matching the width of server cabinets and row heat exchangers or management cabinets. The roof modules are fixed directly to the top plate of the cabinet.
Material – Sheet steel powder painted, mineral safety glass.



Evolving data center technologies lead to a wider use of blade servers and other high power density systems. High energy demand is in almost direct relation to the volume of heat produced by server rooms, and results in the formation of the so-called “hot-spots”. With varied level of generated
heat, uniform cooling distribution systems are incapable of providing sufficient performance.
As an alternative, cold air distribution systems are used and their cooling capacity adjusted to the load of a given server cabinet. Side heat exchangers are perfect for such applications. Installed to the side of a server cabinet, they ensure air circulation and deliver cold air directly in front of the active device.

 Recommended server cabinet configurations for applications with the use of side heat exchangers:
In order to ensure proper air circulation inside the cabinet, the front and rear door should be provided without perforation and with all the accessories that prevent air from being directed to certain areas within the cabinet i.e.: blanking plates, vertical masking panels, horizontal brush strips



With increasing power densities of data centers, air flow management in server cabinets is gaining importance. Cooling IT equipment consists in feeding cold air into a cabinet, supplying it to active devices and discharging it out of the cabinet. If hot air being discharged is drawnin and mixed with cold air at device inlets, the cooling air becomes warmer. As a result, overheatingrelated damage in computer devices may potentially occur. To prevent such issues, it is recommended to use proper blanking plates, masking panels, brush strips and air flow facilitation items.

Air flow guides

Given their design and configuration options, active devices with lateral air flow require special approach in terms of the cool air flow. Special design of elements directing air flow and server racks adapted to the technical specifications of active devices and the manufacturer’s instructions ensure optimum
working environment.
Once we have the specification of network devices with lateral air flow to be installed in our cabinet, we will provide you with the best solution.

Horizontal brush strips

The horizontal brushes are fitted under and over the working surface of the mounting profiles. They are intended for limiting cold air circulation outside the working zone of the mounting profiles and preventing recirculation of hot air into the cold air inlet.
Material – plastic.

Vertical masking panels

The vertical masking panels are intended for sealing the space between the mounting profiles and the side panel. They prevent hot air from being fed back into the cold air inlet.
For cabinets wide 800 mm:
1. Vertical masking panels with cable entries and openings for fixing cable clamps.
2. Vertical solid masking panels with openings for fixing cable clamps.
For cabinets wide 600 mm:
3. Vertical solid masking panels.
The cable entries in masking panels for 800 mm cabinets are covered with a brush and their edges are protected with an edge seal. All three masking panels types are provided with a brush that, once assembled to the cabinet, fits tight to the side wall.
Material – sheet steel powder painted, plastic.

Air flow guide vane

Located at the back of a cabinet, it facilitates the natural flow of hot air generated by an active device towards the top of the cabinet. The vane should be used with “a vertical hot air duct” located on the top plate of the cabinet in order to feed hot air out of the cabinet (via a separate duct) to the air conditioning unit.
Material – sheet steel powder painted.

Vertical hot air duct

Located on the top plate of the cabinet. It forms a channel for hot air flowing between the cabinet and the hot zone. Its modular design allows for height adjustments within a range of 750-1360 mm.
Material – Sheet steel powder painted.

Cold air deflector

The deflector is located on the bottom plate of the cabinet in a spot where cold air is fed from the access floor. It directs the cold air stream towards the front of the cabinet (an area between the front door and the front of active devices). It is suitable for use with cabinets of 600 mm or 800 mm in width and 1000 mm or 1200 mm in depth.
Material – Sheet steel powder painted.
