 IWC is among the industry heavyweights at Power-Gen Africa 2014

IWC, South African leaders in cooling towers and cooling solutions, is currently constructing two towers for Eskom and is among more than 2,000 industry heavyweights that will be present at Power-Gen Africa 2014 later this month.

It is building two four-cell mechanical induced-draft concrete cooling towers for Eskom’s Kusile Power Station in Witbank, South Africa.

These cooling towers form part of the auxiliary cooling system, which will supply cooling water primarily for the turbine and boiler plant auxiliaries as well as compressor cooling and certain other items of the plant.

Each of the cooling towers is designed for a flow rate of 12 000 m³/h and has a heat rejection of 90 MW.

IWC is currently in the throes of commissioning the auxiliary cooling system for the Medupi Power Station outside of Lephelale in Limpopo province.

Here IWC has not only designed and constructed the cooling towers but has also designed and supplied the process equipment needed for the auxiliary cooling requirements.

When completed the Medupi power plant will have six units and require a total of approximately 26,500 000 l/h of auxiliary cooling water for the turbine and boiler auxiliaries as well as some other consumers in the station.

 When asked what IWC can offer power generation companies, company Managing Director Roger Rusch said IWC specialises in making the cooling systems in power plants more efficient, which means lower condensing temperatures, which in turn results in an improvement in the thermodynamic cycle of the power plant.

He said: “We are experts in cooling tower refurbishment that can extend the operating life of power plant cooling towers for another 25-plus years and with properly designed thermal upgrades improve efficiencies resulting in power plants being able to produce more power for less coal.” 

 But this comes with its own challenges as when undertaking refurbishment work on operational power plants cooling towers cannot be taken out of service without major production losses. To address this IWC has patented its own on-line refurbishment technology.

Rusch said IWC has successfully used this technology in a number of natural draught cooling tower refurbishment projects – including projects for SASOL in Secunda and EnergyAustralia in Australia.

In the case of the SASOL refurbishment, this meant that only a small area of the cooling tower could be isolated at any given time, around 10 percent, in order to ensure that there was no significant thermal performance deterioration, which would affect SASOL’S production.

 Explaining the process, Rusch said: “All you are really doing is isolating a relatively small portion of the cooling tower at a given time, finishing that section of it and moving on.

“As you move on through the tower you improve the efficiency with each piece that you’ve worked on so eventually you get to a point where you have very little negative effect on the cooling tower and that allows you to complete the work, improving the performance of it as you go along.”

Looking to the future, Rusch said IWC has recently launched a fibreglass production facility. This facility is capable of constructing large diameter tanks and pipes as ducting of all vital components in the process of Flue Gas Desulfurization or FGD.

This gives IWC the ability to assist existing clients as well as any future partners with the construction of the necessary equipment needed to meet Environmental requirements as outlined in the Air Quality Act No 39 of 2004.

 “We are currently able to assist power plant operators with the servicing and cleaning of plate heat exchangers and are expanding this service to include other forms of heat exchange equipment such as air cooled heat exchangers and condensers,” said Rusch.

As to the reasons for attending this year’s conference, Rusch said the event is the ideal meeting place for those companies involved in the power generation industry.  

“With more than 2,000 high-level professionals from across the industry attending this provides the perfect opportunity to make contact with our existing clients and potential future partners.”

The event will take place in Cape Town from March 17-19.

5 minutes with... Janthana Kaenprakhamroy, CEO, Tapoly

Heading up Europe’s first on-demand insurance platform for the gig economy, Janthana Kaenprakhamroy is winning awards and leading with diversity

Founder and CEO of award-winning insurtech firm Tapoly, Janthana Kaenprakhamroy heads up Europe’s first on-demand insurance platform for the gig economy, winning industry awards, innovating in the digital insurance space, and leading with inclusivity.

Here, Business Chief talks to Janthana about her leadership style and skills. 

What do you do, in a nutshell?

I’m founder and CEO of Tapoly, a digital MGA providing a full stack of commercial lines insurance specifically for SMEs and freelancers, as well as a SaaS solution to connect insurers with their distribution partners. We build bespoke, end-to-end platforms encompassing the whole customer journey, but can also integrate our APIs within existing systems. We were proud to win Insurance Provider of the Year at the British Small Business Awards 2018 and receive silver in the Insurtech category at the Efma & Accenture Innovation in Insurance Awards 2019.

How would you describe your leadership style?

I try to be as inclusive a leader as possible. I’m committed to creating space for everyone to shine. Many of the roles at Tapoly are performed by women and I speak at industry events to encourage more people to get involved in insurance/insurtech. Similarly, I always try to maintain a growth mindset. I think it’s important to retain values to support learning and development, like reliability, working hard and punctuality.

What’s the best leadership advice you’ve received?

Build your network and seek advice. As a leader, you need smart people around you to help you grow your business. It’s not about personally being the best, but being able to find resources and get help where needed.

How do you see leadership changing in a COVID world?

I think the pandemic has proven the importance of inclusive leadership so that everyone feels supported and valued. It’s also shown the importance of being flexible as a leader. We’ve had to remain adaptable to continue delivering high levels of customer service. This flexibility has also been important when supporting employees as everyone has had individual pressures to deal with during this time. Leaders should continue to embed this flexibility within their organisations moving forward.

They say ‘from every crisis comes opportunity’, what opportunities do you see?

The past year has been challenging, but it has also proven the importance of digital transformation in insurance. When working from home was required, it was much harder for insurers to adjust who had not embedded technology within their operating processes because they did not have data stored in the cloud and it caused communication delays with concerned customers at a time when this communication should have been a priority, which ultimately impacts the level of customer satisfaction. This demonstrates the importance of what we are trying to achieve at Tapoly in driving digitalisation in insurance and making communication between insurers and distribution partners seamless. 

What advice would you give to your younger self just starting out in the industry?

Start sooner, don’t be afraid to take (calculated) risks and make sure you raise enough money to get you through the initial seed stage.
