Washbay Pressure in a Busy Benoni Workshop
The client was a heavy workshop in Benoni handling equipment that came in with grease, dust and road grime after long shifts on the East Rand. Their washbay had become a bottleneck. When hot water ran short or temperatures dipped too low, operators had to slow down cleaning, which pushed out handover times and left the next job waiting.
The brief was plain enough: supply a hot water plant that could keep the washbay ready through a full working day, cope with morning peaks and recover quickly after back to back washes. The system also had to suit Gauteng power interruptions, fit neatly into an existing plant area and be serviceable without long downtime. In practical terms, that meant a reliable hot water solution with proper controls, safe access, and enough reserve to keep cleaning moving even when the site was under pressure.
What Held the Job Back
The washbay sat in a busy yard where space was tight and movement was constant. Any new plant had to fit around existing pipe routes, drainage and access for forklifts and service vehicles. The area also saw a fair amount of spray and humidity, so corrosion protection and sensible component placement mattered. Benoni sites can also be unforgiving on maintenance schedules, because if the washbay stops, the whole workshop queue starts to stack up.
There was another issue as well. The client needed a solution that would not become a nuisance during load-shedding or after voltage dips. We therefore planned the installation with restart stability in mind, plus controls that let the operators keep a close eye on water temperature, burner status and circulation without needing a technician every time.
- Tight plant room footprint with limited access for lifting gear
- Need for steady hot water during peak wash periods
- Power interruptions and start-stop conditions
- Corrosion exposure from washbay moisture and cleaning chemicals
Plant Supplied and Installed
We supplied a hot water plant built around an efficient commercial heating package sized for the washbay duty. The installation included a high recovery heat source, insulated storage, circulation hardware, safety controls and the necessary pipe connections to the washbay points. Where the old arrangement had been patched together over time, we replaced it with a proper layout that made maintenance simpler and reduced the chance of unnecessary heat loss.
Key works included a new control set for temperature management, isolation valves for easier servicing, a safe flue arrangement, and improved pipe support and lagging. We also checked the water side for scale risk and set the plant up so the client could keep water quality under control from the start. That matters on Gauteng systems because untreated water can cause faster fouling and poorer heat transfer, especially on equipment working daily.
- Hot water generation plant sized for washbay demand
- Insulated storage and circulation components
- Temperature and safety control set
- Lagged pipework and tidier plant layout
Installation and Commissioning Over Three Weeks
The project ran over three weeks from site assessment to handover. Week one covered measurements, service checks and final layout confirmation. Week two was the supply and preparation stage, where we fabricated the support work, prepped the pipe connections and coordinated shutdown windows so the client would not lose more time than necessary. Week three was installation, pressure testing, burner setup, combustion tuning and final commissioning.
During commissioning we checked water temperature rise, recovery time and system stability under repeated draw-off. We also trained the site team on the daily checks that matter most, such as pressure, temperature, leaks and basic visual inspection. The result was a plant that could be handed over with clear operating steps and a practical maintenance plan, not a mystery box that only one person understood.
Results at the Washbay
Once the plant was online, the washbay could keep up with the workshop pace much better. Water stayed hot enough for quicker breakdown of grease and dirt, which improved cleaning quality and cut the time spent reworking difficult jobs. The workshop team could move vehicles and equipment through the bay with fewer pauses, so turnaround improved and the bay became a proper support point instead of a hold-up.
There was also a maintenance benefit. Because the new system was planned as a single managed plant rather than a collection of mixed parts, servicing became easier to schedule and easier to explain to the site team. The operators reported steadier performance through the day, including during periods when the power supply was less predictable.
- Improved washbay readiness throughout the shift
- Shorter cleaning and turnaround times
- More consistent hot water temperature at point of use
- Cleaner maintenance access and easier daily checks
What We Would Repeat on a Similar Site
If we were starting a similar washbay job again in Benoni or anywhere else on the East Rand, we would follow the same approach: confirm the duty pattern first, design for actual peak use, and build in enough recovery to handle back to back washing without frustration. We would also keep the controls straightforward, because a workshop floor needs equipment that is easy to run at 6 am, after a power dip, or when the foreman is juggling three other jobs.
We would keep treating water quality as part of the project, not an afterthought. In this part of Gauteng, scale and heat loss can creep in quickly if the plant is left to run hard on untreated water. For coastal work we would specify stronger corrosion protection, but even inland sites benefit from sensible lagging, neat pipework and a maintenance schedule that is actually followed.
