Close control air conditioners

 Dantex informs about starting of a new precision (close control) air conditioners series production.

These devices are designed for the most precise maintenance of the microclimate parameters in rooms where some technological or experimental equipment is situated.

Modern precision air-conditioning systems reliably look after the equipment. Unlike comfort air conditioners, which provide air conditioning for offices, for example, they not only ensure the right temperature, but regulate air humidity and therefore prevent electrostatic charge as well.

Precision air-conditioning systems are designed for failure-free, continuous operation over many years. Compact versions in rack size can fit anywhere. They work away quietly, reliably and exceptionally economically to keep the eqipment available at all times.
Communications network cooling requirements differ from typical commercial or "comfort" requirements, in the following significant ways.

Year-Round Operation

Commercial cooling systems may be required to operate only during summer months and during normal working hours. Communications sites, however, generate heat 24 hours per day, 365 days per year

Temperature Control

As telecom equipment generates large quantities of heat in small areas, six to ten times the heat density of normal office space, the air conditioning system must have more than just enough cooling capacity. It must have the precision to react quickly to a drastic change in heat load and prevent wide temperature fluctuations, which is something a large building system cannot do.

Humidity Control

Telecommunications equipment must be protected from both internal condensation and static electricity discharges. Maintaining the correct humidity level in the computer room is just as important as maintaining proper temperature. Too high a humidity could cause condensation within the telecom equipment and the potential for hardware damage. If humidity is too low, static electricity could disrupt operation or even shut down the telecom system. An ordinary building system cannot normally control the environment within these boundaries.

Air Volume

Telecommunications equipment requires greater air volumes than ordinary air conditioning can provide. The high-density heat load in a relatively small space requires more changes of air than a less dense "comfort" application. While a normal office space requires only two air changes per hour, a telecom room requires up to 30 changes per hour. Without proper air volume, hot spots and temperature fluctuations could develop within the space. Also, greater air volumes provide the higher sensible heat ratios required by telecom equipment.
