Tobacco systems
Tobacco curing tunnels for an even cure.
Our flagship system, and the one we used and improved on our own crop before selling it to other farms. Heat and air move evenly through the whole load, so the cure comes out the same end to end, with each lane run at its own temperature.
Why the whole system matters
How well a tunnel cures comes down to the whole system, not one part.
The building, the heat source, the fans, the trolley layout and how you load it all decide how the cure comes out. We work the whole system out together during the farm visit, then supply the drawings and working components that make it cure properly.
- 01
Heat source, fans and airflow matched so the whole load cures evenly.
- 02
Trolley layout and loading planned around how you reap.
- 03
Comes with trolleys, traverses, white PPGI ceiling and two steel decked trailers.

How we think about it
A good cure comes from getting the whole system right.
Tunnel structure
Planned around the selected RS model, loading direction, access and future expansion where applicable.
Airflow package
Fans and air routes are matched to move air through the loaded tobacco rather than around it.
Heat transfer
Heat exchanger choices are made around curing capacity, fuel availability and efficiency.
Trolley handling
Trolleys and Talita clips help reduce loading time and keep the curing process more organised.

Questions worth settling before you buy.
It depends on crop volume, available space, loading method, fuel supply and how much room you want to grow into. As a rough guide, a single ROC site cures around 80 hectares of tobacco, which is the size we recommend. Tell us your numbers and we'll point you to the right model.
Included with every system
Support comes with the system.
Farm visit and sizing
We look at crop, site, fuel, power, buildings and workflow before sizing the system.
Build check-ins
We supply the drawings and check the build at key stages while your builder handles the brickwork.
Season support
Calls, setup help, troubleshooting and practical advice are part of the system.
Related equipment
Often part of the same job.
