Cold aisle containment solutions increase your cooling efficiency whilst reducing power consumption.
Cold aisle containment is a method of increasing cooling efficiency, reducing power consumption and is intended to prevent air temperature zones from being mixed together in a data centre.
Cold air is fed through a false floor into a contained cold aisle. This air flows through the front of the server racks, removes the heat from installed equipment and is expelled as hot air through the rear of the cabinet. The hot air is then removed by the data centre air conditioning system.
Having the cold aisle contained means the area requiring cooling is much smaller and therefore less power is required by the C.R.A.C (computer room air conditioner) unit to keep it at the recommended temperature.
Cold aisle containment ensures businesses do not have to increase the cooling capacity within the data centre whilst increasing cooling efficiency and reducing costs.
Features
The main benefits of cold aisle containment are:
Avoids hot air short circuits
Reduces the volume of air that needs to be cooled
Improves efficiency of the cooling system considerably
Energy cost savings
Installing a cold aisle in a workplace improves the working environment for staff, as the room does not need to be kept at a low ambient temperature. Even the cold aisle can often be warmer than that of an uncontained data centre. An uncontained data centre needs to have it’s air conditioning set for the installation that requires the most cooling, where ever that is within the data centre.

SITRANS Probe LU is a 2-wire loop powered ultrasonic transmitter for level, volume and flow monitoring of liquids in open channels, storage vessels and simple process vessels.
The SITRANS Probe LU is ideal for level monitoring in the water and wastewater industry and chemical storage vessels.
The range of SITRANS Probe LU is 6 or 12 m (20 or 40 ft). Using Auto False-Echo Suppression for fixed obstruction avoidance, as well as an improved signal-to-noise ratio and improved accuracy of 0.15% of range or 6 mm (0.25″), the Probe LU provides unmatched reliability.
SITRANS Probe LU includes Sonic Intelligence® signal processing from the field-proven Probe and incorporates new echo processing features and the latest micro-processor and communications technology. The Probe LU offers two communications options: HART or PROFIBUS PA (Profile version 3.0, Class B).
The transducer on the Probe LU is available as ETFE or PVDF to suit the chemical conditions of your application. As well, for applications with varying material and process temperatures, the Probe LU incorporates an internal temperature sensor to compensate for temperature changes.
Key Applications: chemical storage vessels, filter beds, liquid storage vessels.
Supplementary Components are designed to work with most types of instrumentation to provide enhanced functionality such as remote displays and remote monitoring solutions.
Don’t forget that the safest engineered level measurement solution includes switches for back-up, overfill, low level and dry run protection.
