Jet Park plant needed temporary cooling, not downtime
The site was a manufacturing operation in Jet Park, Ekurhuleni, running a temperature-sensitive process line that could not afford a long stop. The client had planned maintenance work on the permanent cooling side and needed a temporary hire solution to cover the gap for the full shutdown period. The main concern was simple, keep product and process temperatures stable while the maintenance team worked through the plant schedule.
Our brief was to supply a temporary water chiller that could be installed quickly, operate reliably over several weeks, and fit into a busy industrial yard with limited space around the plant room. Because the shutdown timing was fixed, the equipment had to arrive ready for connection, with the right hose interfaces, pump capacity and control settings for the load on site.
What the site had to work around
This was not a clean-room type job where everything sits open and easy to reach. Jet Park sites often deal with tight access, forklift movement, dock activity and a mix of old and new pipework. There was also the usual seasonal pressure of Gauteng heat, and the team did not want temperature drift while maintenance was underway.
We also had to account for power availability and the fact that the temporary unit had to run alongside other plant loads. The client wanted a unit that could handle normal production demand, but also give enough headroom for warmer afternoons and short load fluctuations. In practical terms that meant the hire package had to be sized correctly, not just switched on and hoped for the best.
- Tight installation area with limited laydown space
- Existing pipework that needed adaptation on site
- Fixed shutdown dates with no room for delay
- Continuous operation across day and night shifts
Temporary chiller hire and connection details
We supplied a packaged industrial water chiller sized for the application, complete with circulating pump support and the control setup needed for steady process water delivery. The unit was positioned outside the plant room, connected into the existing circuit through temporary pipework, and commissioned to match the site’s required temperature range.
The hire arrangement included startup support, checks on flow rates and return temperatures, and practical guidance for the operators on how to keep the system stable during the maintenance window. We also verified that the hoses, fittings and isolation points were arranged so the maintenance team could work without fighting the temporary system.
- Hire chiller supplied as a ready-to-run package
- Approximate cooling duty: 120 kW
- Process water supply range: 7 to 12 degrees C
- Integrated pump set for stable circulation
- Temporary flexible pipework and connection accessories
- On-site commissioning and operator handover
Timeline from enquiry to running water
The project moved over a short planning window of 2 weeks, which suited the client’s maintenance schedule. The first week covered site assessment, load confirmation and the connection plan. During that stage we checked the available space, inlet and outlet positions, and the most practical route for temporary pipework.
In the second week the hire unit was delivered, set in place and commissioned. Once the system was running and temperatures were steady, the client’s maintenance team could continue with their own shutdown tasks knowing the cooling side was covered. There was no need for stop-start operation or emergency intervention, which was exactly what the site needed during a planned outage.
Results during the maintenance shutdown
The temporary chiller kept production support active throughout the shutdown period and prevented the line from overheating while the permanent equipment was offline. That protected product quality, reduced stress on downstream equipment and gave the maintenance team the time they needed to complete the planned work properly.
The client also benefited from having a supplier who could handle the practical side, not just drop off a machine and leave. We checked operation after startup, confirmed the temperatures held under load, and remained available while the hire unit was in service. For an industrial site in Gauteng, that kind of support matters when downtime costs build up quickly.
- Production support maintained through the shutdown
- Process temperatures held within target range
- Maintenance work completed without cooling-related delays
- Operators had clear guidance during the hire period
What we would repeat on the next Jet Park hire
If we were doing the same type of Jet Park hire again, we would follow the same sequence: load check first, connection plan second, then delivery and commissioning only once the site is ready. That avoids last-minute changes and keeps the installation smooth, especially where access is tight and the shutdown window is fixed.
We would also recommend early discussion about water quality, because temporary systems can still suffer from scale, debris and corrosion if the site water is not checked. A quick water treatment check before startup can save a lot of trouble later, especially on plants running long hours or exposed to warm summer conditions. For sites in Ekurhuleni, it is better to sort that out before the unit goes live, not after a blockage or fouled exchanger appears.
For this Jet Park project, the result was straightforward: the client kept operating, the shutdown work stayed on schedule and the temporary chiller did its job without drama. That is exactly how hire cooling should perform.
