​City Park - Dallas Parks, TX Siemens Robicon VFD Refurbished

Dallas County Park City MUD serves Highland Park and University Park. There are 14,798 connection points between them and a population of 32030. The project involves replacing two existing 1000HP, 4160V Robicon Perfect Harmony drives, which are in an "end of life" state. We have to overcome many major challenges in this project. First, the customer wants to utilize the existing ducts in the power source and motor load, so we must ensure that the VFD fits the existing space in size. The new VFD is actually smaller than the existing VFD, so we must design and add a vertical section to make the VFD larger to ensure that it covers the existing pipeline. Another major challenge that must be overcome is that the customer wants to exhaust the VFD exhaust pipe from the control system. This is one of the cooling methods provided by Siemens for its MV drive system. By exhausting hot air from the building, the operating cost of the VFD is actually reduced. The customer’s room is large enough and has proper ventilation to provide the appropriate supplemental air needed to flow through the VFD. Together with the contractor and Siemens, we provided a system design that will partially use the existing ductwork and route it to the new VFD. Finally, we are able to provide a highly engineered VFD system delivered after 20 weeks. The use of this VFD allows Dallas Park City MUD to more accurately control the process and keep its water distribution system close to tolerances.

Thank you for your outstanding performance in this work. I feel very honored to work with each of you and I hope to be able to work with you on future projects. Thank you. Sincerely, Brent Jordan
