Chemical Dosing Systems from 3D Models – The Quality Way

Designed first digitally and built from the 3D model

Know what you’ll get, before it’s built

When you buy a car, you can see it in the showroom before you buy it. When it arrives, it is exactly as you had envisioned and there are no (nasty) surprises. With Dioxide Pacific, it’s the same with everything we build. It may be a standard product like our Electricide® chlorine/chlorine dioxide generators or a bespoke chemical dosing skid. Either way, we always produce a 3D model of the system using Autodesk Inventor, which becomes the template for our staff to build the item. Generally, we don’t produce 2D fabrication drawings as we find the 3D model is easier and more accurate to build from. When you order a system, you’ll be provided with the 3D model and the ability to view the model from different angles; parts transparent or hidden and measurement tools. You can ask for changes to be made at that time until you are happy with the layout. The built system will be exactly the same as the 3D model you have approved. It will fit in the space you have allocated and connect to services exactly as promised.

Sodium Hypochlorite Dosing Skid for Water Authority

Dioxide Pacific recently designed and built a chemical dosing skid for sodium hypochlorite for an odour scrubber. The dosing skid is a powder coated stainless steel frame with Fiberstrut base, HDPE sides and a polycarbonate splash screen. Metering pumps ProMinent Sigma/3. All accessories including actuated ball valves, mag flow meter, pressure gauge and pulsaton dampener are fixed to the HDPE back using Fiberstrut bolts and pipe clamps.

The 3D model was developed from the P&ID and approved by the customer prior to fabrication.

When complete, the skid was tested at our works and delivered to site. Time frame from approval of the 3D model to delivery was 4 weeks. This short time frame was critical to the customer.

Fiberstrut for Dosing Pump Stand and Skid – 100% Chemical Resistance

Posted on by Paul

Fiberstrut vinylester channel, fasteners and brackets are ideal for construction of chemical dosing skid frames where 100% chemical resistance is desired. For chemicals like sodium hypochlorite, hydrochloric acid, sulphuric acid, fluorosilicic acid (FSA) ferric chloride and chlorine gas, dosing skids have traditionally been constructed from gal steel or stainless steel and subsequently epoxy painted. Of course, the painted steel looks good for the first few weeks. Eventually, the base metal corrodes either from a chemical spill or from chemical fumes. The result is an ugly plant room, costly removal of equipment and replacement of channel and fixings some months down the track.

One of our customers recently provided chemical dosing skids for a water authority to replace existing skids that had corroded and failed. They chose to use Fiberstrut channel to mount dosing boards to the wall and for fabrication of pump stands. The stands were assembled from cut pieces of Fiberstrut vinylester channel, angle brackets, bolts, nuts and post bases. One key feature is chemical resistance. The dosing pumps will require maintenance and when disconnected, some chemical may drip onto the pump stands. If this happens, the chemical can be washed off and no corrosion will occur.
