Client’s Needs

This factory in Victoria sports a number of activities and machinery including plasma cutting and welding services.

The company contacted Solar Whiz needing increased ventilation as well as additional fume and heat extraction. The 4 existing commercial-grade whirlybirds that they already had installed on the roof were not meeting their requirements.

 

Our Solution

We replaced the old existing commercial whirlybirds with 4 of our own SW-AU-C-10000 units. Fortunately, we were able to retrofit our own flashings onto the holes left by the whirlybirds. This meant that we were able to make use of the existing holes in the roof and significantly reduce the installation costs because it wasn’t necessary to replace the sheets where the whirlybirds had been installed.

The units were installed above the large industrial plasma cutter and are well-placed to extract the fumes that it generates.

 

The system works by extracting the fumes generated by the plasma cutter and replacing them with outdoor air. This replacement air is clean and cool, helping to maintain a healthy and comfortable work environment. The system has also been backed up by a night operations kit so that the units can operate at full capacity (if required) overnight or in overcast conditions. This works by attaching the units to mains power. The units only ever take the energy that they need to top up operations and a maximum of 24 watts can be drawn. This is an incredibly cheap and efficient use of energy to ensure that the fans are operating at their highest performance level.

 

Results

Because this installation was done in parts we could monitor the difference in performance at each stage. After we installed the first unit we were able to determine that a single SW-AU-C-10000 unit was having more of an impact than all 4 of the original whirlybirds combined. This really shows how powerful and effective our units are.

The improvement in airflow and gas extraction from the plasma cutter was remarkable. The speed at which air was moved in and out of the building was incredibly impressive and had immediate positive impacts. The indoor environment is much more comfortable and the air quality is significantly better.
