3500 anticondensation heaters will be used in switchgear panels in the world's tallest building.
Pentagon Electrical Products has received an order for 3500 anticondensation heaters to be used in switchgear panels for the Burj Dubai, which is expected to be the world's tallest building when completed during 2009.
The order has been received from ETA/PCS and represents the largest order the company has received to date for these products for use on a single project.
The Burj Dubai (Dubai Tower) will form part of a development incorporating 30,000 homes, nine hotels, six acres of parkland, 19 residential towers and a 12 hectares man-made lake surrounding the dramatic centre piece Burj Dubai structure.
The triple lobe shaped footprint of the building is based upon a native desert flower and everything about the project is impressive.
With a structure height of 808m, the building contains 162 floors, with the highest residential level on floor 109, and an observation deck on number 124.
The structure sits on 192 piles set to a depth of more than 50m, with 45,000m3 of concrete weighing in excess of 110kt making up the massive foundations.
With daytime temperatures that can exceed 48C, and nighttime as low as 9degC, coupled with relative humidity levels which have reached 98% in Dubai, it is no wonder that Pentagon Electrical exports 35% of its anticondensation heaters to the Middle-East and Far-East regions.
This is complemented by 12% of their power resistor production also being sent to the same markets.
The anticondensation heaters manufactured by Pentagon comprise low voltage vitreous enamelled resistors housed in perforated enclosures.
Good air movement and convection is created, while preventing direct contact with the heating elements.
The heaters can be supplied in nine power ratings from 20 to 120W, with optional input supplies of 110 or 240V AC.
The constant gentle level of background heating provided is ideal for preventing moisture build-up in confined areas such as switchgear panels, where dynamic braking or other power surge heating can dramatically increase localised heat conditions.
