CoolControl Curtain
Inexpensive cold-aisle-containment with
fire retardant curtains
CoolControl Curtain allows the containment of racks of any size along the
cold or hot aisle. The solution consists of an inert and anti-static material that is
also self-extinguishing according to the EN DIN 53382 norm. The curtain fits to any
rack height and width and is easy to install especially in data centres that have
grown over time with racks from different vendors. Cold-aisle-containment with
CoolControl Curtain in the data centre contributes to a reduction of the CRAC power
consumption by up to 30 percent.
Re-circulation of hot air at the IT equipment intake can
lead to increased hardware failures and proves to be
expensive
Active IT hardware takes the cooled air in from the front of the racks and
passes it to the back of the racks. As the cool air travels through the hardware, the
air is heated and pushed out the back. The hot air rises up the rear of the cabinet
and flows over the top or around the side of the rack and re-circulates to the front
of the rack in the cold aisle again. The hot air can also re-circulate through open-
ings between servers or other hardware in the cabinet. As this process repeats,
the temperature in the cold aisle gradually rises creating hot-spots. Traditionally,
the most common way to prevent these hot-spots was to increasing cooling output.
Unfortunately, increasing cooling output increases energy consumption and your
energy bill and does not always solve the problem. It is essential to hermetically
separate the hot air from the cold aisle. This separation can be done reliably with
the CoolControl Curtain. Our measurements show that by installing CoolControl
Curtain the temperature difference between the hot and cold aisle can be as high
as 10-15 degrees Celsius. Depending on the size and environmental specifics
of individual data centres, the cooling requirements and energy costs could be
decreased by as much as 30%.
Play it safe: Test before installing a permanent cold aisle
containment solution
For companies who want to first test the efficiency of cold aisle contain-
ment the CoolControl Curtain is ideal. With the CoolControl Curtain, Facility
Managers and IT Managers can measure the actual savings and efficiency factors
without placing strain on their budgets.
