Cover Story - Curries’ DVM S – drastically cutting energy costs

This edition’s cover photograph and story is by Fourways Airconditioning and deals with a Curries’ DVM S installation that drastically cuts energy costs in an old building by replacing an old chilled water system.


Renovating an out-of-date HVAC system in a building over 25 years old presents quite a challenge – and one which is multiplied several times over when the building is fully occupied. Not only was renovation of the HVAC system required, but the original chilled water system is being completely replaced with a modern Samsung DVM system with heat recovery for maximum electricity cost-savings, supplied by Fourways Airconditioning.


The building in question is President Place in Rosebank and the tender was awarded to Curries Air. A 220-ton crane was required to hoist the 26 Samsung DVM condensers onto the roof in the space of one day, necessitating a closure of the adjoining street.


The old chilled water system had electric resistance heating, so large energy savings are anticipated once the new heat recovery DVM system is finally commissioned by the end of this year.


Ian Wingrove of Wingrove Consulting Engineers was involved from the start, and through a tender process, Curries Air was awarded the installation. The President Place building consists of two wings, each seven stories, with a central double-volume atrium. Working with Wingrove as well as Sello Ramatswi and Mfundo Ciko of Fourways, it was decided to break the system down into 13 components with an average of 25 ducted indoor units serving the various floors of the two wings.


‘We did this,’ says Currie, ‘to assist in the installation process and to ensure that in the event of one area encountering a problem, the entire system wouldn’t have to be shut down.’

Along with Wingrove Consulting Engineers, the on-site operation was jointly managed by Andrew Currie and Quintin van Wyk of Curries Air. Old chillers, together with the existing chilled water piping, were removed and the central ‘backbone’ of the new DVM system installed.


Fourways Airconditioning – serving the whole of South Africa and beyond

This was just one of the many projects that Fourways Airconditioning are proud to have been involved in. From selling home airconditioning units and spare parts from a small outlet in Kya-Sands, to being involved in big projects in the VRF market from inception to completion upon commissioning, has ultimately become the backbone of Fourways Airconditioning’s business offering.


The growth of Fourways has been meteoric. Since 1999, Fourways Airconditioning has grown to become a national – and international – operation, offering a wide range of airconditioning systems and equipment, as well as domestic and commercial heat pumps. Their new baby, an appliances division to supply home appliances as well as TV and audio equipment for bigger tenders and projects, has also been introduced as part of Fourways’ projects/tenders division offering.


‘We found some of our clients requesting a complete turnkey solution’, says Richard Perry, Managing Director of Fourways Aircon. ‘We started this division to provide a single source of various product ranges when it comes to projects like new-age apartments, hotels and B&B’s requiring not only HVAC systems, but also appliances.’


Today, Fourways has nine branches nationwide, each with its own warehousing and support facilities, as well as a branch in Mauritius. A dedicated export division supplies products into the SADC region and is also involved with projects as far away as the Seychelles, Nigeria and Gabon.


Fourways holds stock and spares in roughly 10 000m² of warehousing, supplying thousands of installers. This has enabled Fourways Airconditioning to rapidly supply products for a wide variety of projects across the length and breadth of South Africa. Some of these include The Nelson Mandela Children’s Hospital; the Department of Education in Braamfontein and Google Head Office with a supply of Alliance water heaters.


The latest and one of the biggest projects Fourways has been involved with is Capitec bank where Jai Air, one of Fourways’ biggest installers, are installing Samsung R410A airconditioners, not only in new Capitec branches around the country, but also upgrading existing branches due to the phasing out of ozone depleting substances such as R22 gas.


Nationwide Fourways technical support

Not only does Fourways Airconditioning provide nationwide supply, it also offers complete after-sales back-up. Technical support – on-site as well as a dedicated engineering team providing assistance with the design of complex DVM systems using AutoCAD – is all part of Fourways’ service. Working with installers, consulting engineers, developers and architects,


Fourways has helped to provide cost- and energyefficient solutions for literally thousands of projects. ‘It’s important not to forget about the basics, I believe that it is because of the after-sales back-up and support we provide our customers with that we have been privileged with our exponential growth. It all comes down to one word: service. We are constantly looking for new ways of improving our service to our customers,’ comments Perry.
