Led from Alrode with a hands-on standard
Raynen is based in Alrode, Alberton and the team works with the same focus on every job, whether it is a planned installation in Johannesburg or an urgent breakdown in Durban. The business was founded in 2008 and that experience shows in the way each person understands plant conditions, site access, municipal rules and the pressure that comes with downtime.
MD Riaan van der Merwe sets the pace for the business and keeps the standard practical. He works closely with clients who need reliable cooling for production, and his focus is always on equipment that suits the application, the water quality and the day to day demands of the site.
- Industrial water chillers for lasers, moulds and process lines
- Support across Alberton, Johannesburg, Pretoria, Durban, Cape Town and Rustenburg
- Service planning that takes load-shedding and shift work into account
Operations and project coordination that keep jobs moving
Lerato Mokoena manages operations and keeps the work organised from first enquiry through to handover. She coordinates visits, parts timing and site information so technicians arrive ready, which matters when a line is down and every hour counts. Her approach is calm and practical, especially on multi-site work where access, lifting equipment and shutdown windows all need attention.
Anika Naidoo handles projects coordination and keeps the moving parts together when a chiller install or upgrade involves more than one step. She works with schedules, client updates and job packs, helping to make sure commissioning, pipework and any control changes are lined up properly. On busy weeks, that detail saves a lot of back and forth.
- Job planning for installations, retrofits and temporary cooling
- Co-ordination with production teams and site managers
- Clear handover notes for maintenance and support teams
Technical sales that starts with the application
Pieter Joubert is the Technical Sales Engineer and he spends time understanding what the process actually needs before recommending a unit or modification. He looks at heat load, duty cycle, ambient temperature and how the system will behave in South African conditions, from coastal humidity in Durban to hotter inland sites around Gauteng. That practical approach helps clients choose the right cooling setup first time.
He also advises on cooling audits, operator training and water treatment checks, because a chiller is only part of the picture. If water quality is poor or pipework is undersized, even a good unit can struggle. Pieter works with the service side as well, so the advice is grounded in what can be maintained on site.
- Application-based sizing and selection
- Cooling audits for production stability
- Support for lasers, moulds and process lines
Service support when production cannot wait
Sibusiso Dlamini is a Senior Service Technician with a strong focus on breakdown repairs, refrigeration repairs and pump replacements. He is often the person clients want on site when temperatures start drifting or a fault needs tracing under pressure. He knows that good service is not just about fixing a fault, but about finding the reason it happened and preventing repeat issues.
Nomsa Khumalo leads customer support and keeps communication clear from the first call to the final report. She makes sure clients know what is happening, what parts are needed and when the next step will be. In a busy factory environment, that kind of follow through matters just as much as the repair itself.
- Breakdown response across South Africa
- Refrigeration repairs, pump changes and control checks
- Customer updates that keep maintenance teams informed
Workshop care and on-site reliability
Thabo Maseko supervises the workshop and keeps the smaller details in order, from component testing to prep before a unit goes back out on the road. His work supports everything from preventative maintenance to temporary cooling setups, and it helps ensure equipment leaves the workshop ready for the site conditions it will face. That includes dust, vibration and long running hours.
The workshop team also supports pipework retrofits, control panel upgrades and water treatment checks, especially on older systems that need a better fit for present day production. On many sites a few practical changes can improve uptime more than a full replacement, and Thabo keeps an eye on what can be repaired, what should be upgraded and what must be replaced.
- Workshop testing and preparation
- Support for ageing systems and phased upgrades
- Practical maintenance for industrial plants and factories
A team built for local industry
Raynen’s strength lies in how the team works together across branches and service areas, from Alberton Depot and Germiston Service to Boksburg Service, Pretoria Service and the coastal routes. Everyone understands that a chiller failure can affect output, product quality and deadlines, so the response needs to be steady and well planned.
Whether the work is chiller installation in Cape Town, a temporary cooling requirement in Rustenburg or operator training in Johannesburg, the team brings local knowledge and a practical manner. Clients contact Raynen through the enquiry form on the contact page and the right person follows up from there, no fuss.
- Local support with national reach
- Planned maintenance and emergency response
- Service for factories, moulding plants and laser applications
