An agreement has been signed between ACTOM Mechanical Equipment and its main international technological principal, Fläkt Woods, in which the local company has been appointed the sole agent in Southern Africa for Fläkt Woods’ world-class modular heating, ventilation and air-conditioning (HVAC) systems.

ACTOM Mechanical Equipment has a longstanding association with Fläkt Woods of Europe extending over many years involving use of its advanced fan technologies and manufacture and sale of its axial flow and centrifugal fans for industrial and mining ventilation applications.

The new agreement is the first in which ACTOM Mechanical Equipment has linked up with Fläkt Woods in the field of HVAC technology and equipment.

“The agency agreement with Fläkt Woods’ Climate Control division, which came into effect in May this year, is for their cutting-edge air handling units for HVAC applications. The product is manufactured and assembled in Sweden and in terms of the agreement we provide all the sales and marketing services into the local market, plus after-sales service support on the product, incorporating spares, repairs and maintenance,” said Nuno Pereira, ACTOM Mechanical Equipment’s Product Manager, HVAC.

The Fläkt Woods modular air-handling units, already well-proven worldwide, offer significant advantages over the traditional HVAC technologies by enabling quick and easy assembly and interchangeability of the various components.

“The modular design means that the components – consisting of fan, filters, silencer, humidifier and heat recovery system – are self-contained, so that during the original design and assembly phase the ready-made modules of the required capacity for the particular application are selected and assembled quickly and efficiently. The same applies to repair and replacement of components, with only the module requiring attention being dealt with without any of its companion components having to be interfered with,” Pereira explained.

The Fläkt Woods air-handling units are also highly heat- and energy-efficient and hygienic. Among their various superior features are an advanced energy-efficient heat recovery system, use of direct-drive plug fans, in preference to the conventional belt-driven fans, and of electronically commutated motors, in preference to synchronous motors, to ensure more accurate and speedier responsiveness. “Eighty-five per cent of the life-cycle cost of an air-handling unit is energy, so the gains offered by the Fläkt Woods system are massive,” Pereira pointed out.

ACTOM Mechanical Equipment and Fläkt Woods’ Climate Control division have already landed their first local contract – for the supply of 60 air-handling units for the University of Botswana’s 450-bed new Academic Hospital currently under construction in Gaborone, Botswana, for which deliveries are will start later this year and completed in February next year.

The contract was awarded by the joint venture contractor, comprising Enviroware Construction of Midrand, Gauteng, and Pipework Services of Botswana.

Paul Norton, Chief Mechanical Engineer of the consulting engineers on the project, Gaborone-based North Atlantic Engineering Consultants, said: “We specified use of Fläkt Woods air-handling units as our design required a tried-and-tested quality product that would combine high levels of energy recovery in 100% outdoor air systems, which serve most areas of the hospital. This requirement is met by the predominant use of the innovative Econet system.

“The Econet system provides heat/coolth air-to-water recovery between the supply and exhaust air streams, along with the facility to simultaneously add further heating and cooling. All these features are integrated into a packaged common circuit as compact heating/cooling coils, variable speed pumps, insulation and control system, etc. The result is a shorter and more compact air-handling unit.

“Furthermore, the Econet system contributes to achieving high chilled water system design operating temperature differences of up to 11 degrees C, which significantly reduces water flow rates, with subsequent savings in pumping energy and distribution pipe sizes. The Econet performance is further enhanced by use of direct evaporative cooling in the exhaust air-stream of the air-handling unit,” Norton concluded.

ACTOM (Pty) Ltd is the largest manufacturer and distributor of electrical equipment in South Africa, employing about 6 000 people and with an annual order intake in excess of R5bn. It is a black empowered company with 33 operating units, 27 production facilities and 28 distribution centres throughout South Africa.

ACTOM partners Alstom France for environmental equipment and in serving the maintenance, upgrade and retrofit market for larger boilers, as well as for railway transport activities.

ACTOM holds exclusive distribution, technology and representation rights for Alstom Grid (formerly the Transmission business of Areva T&D) in Southern Africa and maintains management, technical and commercial links to Alstom Grid business units in Europe.

Following the acquisition by Schneider Electric of the global Distribution business of Areva T&D, the distribution, technology and representation agreements that existed between ACTOM and Areva will remain in place until such time as a new agreement has been concluded.

ACTOM formerly traded under the name Alstom South Africa and re-branded to ACTOM in September 2009.
