Enclosed Conveyors

Premron CHS

Enclosed Belt Systems (EBS)

Enclosed Belt Systems (EBS) use a 'tear drop' shaped enclosed pouch which ensures 'dust free' conveying of raw materials. In 2019, Logitech Engineering assisted Premron CHS to build, commission and certify a new enclosed underground coal conveyor system in Central Queensland.

The Premron CHS Conveyor is supported by a trolley system mounted on a monorail attached to the ceiling of the underground passage. Each trolley is approximately 3m long and is linked via a hitch and fitted to the monorail beam via girder trolleys. The trolley system allows the enclosed conveyor to automatically tram behind the Continuous Miner using the mono-rail, but can also negotiate tight radius corners to move out of the way of the Continuous Miner when required.

The conveyor's narrow width does not impede ventilation through the tunnel, and service vehicles can pass along the side of the conveyor to access the Continuous Miner. Power and services, including the ventilation duct, can be run along the monorail independent of the Premron CHS, or attached directly to the trolley system, which keeps all service pipes and cables safely off the ground.

Materials Handling

Ship Loaders

Ship Loading and Unloading

In the last 12 years, Logitech Engineering have been directly involved in the construction and commissioning of eight ship loading and unloading Jettys, including:

  • LNG Loading (QCLNG, GLNG, APLNG and Wheatstone)
  • Coal Loading (WICET and GPC)
  • Iron Ore, Chromium and Manganese Loading (Port Hedland)
  • Bauxite Unloading (QAL and Yarwun Alumina Refineries)
  • Cotton Seed and Magnetite Loading (BHP Gladstone)
  • Sugar and Wood Chip Loading (QSL Bundaberg)

Power and Lighting

Power and Lighting

Area Lighting using 3D LUX Modelling

Safe egress lighting and general area lighting is critical to maintaining a safe operating plant for your employees. Logitech Engineering use 3D LUX modeling calculations to ensure appropriate selection and sizing of light fixtures and support structures. We design and install swivel poles, and winch access mechanism for light poles and towers.

3D Modelling

3D Model

Electrical System Modelling

Modelling electrical systems and cable layouts using 3D programs such as SolidWorks ensures that equipment access and support brackets are optimized, and that the capacity of the cable support systems are adequate for the application and future needs.

Logitech Engineering use a combination of 3D modelling and power managment programs such as PowerCAD to verify protection settings and ensure correctly sized hardware and accurate cable lengths.

PLC and SCADA

PLC Automation

PLC Automation and SCADA

Logitech Engineering's largest design team is the Automation and Controls Group (Logitech Controls). With expertise in virtually every brand of PLC / SCADA / DCS control system on the market. Logitech have programmed and commissioned thousands of systems across Australia, South East Asia and Europe - ranging from small packaged equipment with just a few I/O points to full scale distributed control systems exceeding ten thousand I/O points.

Logitech Engineering have partnerships with Schneider, Allen Bradley, Siemens, Honeywell, Yokogawa and Citect - for design, programming and system integration.

Arc Furnace

Arc Furnace

Smelting and Metal Purification

In 2011, Logitech Engineering commissioned the only DC Arc furnace in the world that is connected to Gas Turbines which are not connected to the power grid. This is significant since the DC Arc requires 18MW of instantaneous power to create the Arc, and also dumps this power instantly whenever the Arc is lost. We designed and commissioned a large 11kV / 2.4MW load bank and a very large reactor and capacitor bank to create a system that worked reliably, without tripping the Gas Turbines.

Biogas Clean Energy

Biogas

Biogas and Clean Energy Recovery

In 2015, Logitech Engineering joined forces with Prizm Engineering and Zinfra to design and commission Queenslands newest Biogas energy recovery systems in Rockhampton and Brisbane for Teys Australia. These large scale units convert abattoir discharge effluent from the Teys meat works to generate methane for boiler feed gas. The biogas is burned to create steam for the plant, while the cleaned and phosphate reduced water is safely discharged to the river.

Instrumentation Packages

Instrumentation Packages

Instrumentation and Control Packages

Logitech Engineering can design, fabricate and commission almost any piping package to suit your application, with recent packages including:

  • Burner Management Systems (RioTinto)
  • Glycol Heater Packages (Chemeq)
  • Chlorine and Potassium Dosing (GRC)
  • Waste Treatment Dosing (Googong WTP)
  • Caustic Cleaning (Yarwun Alumina Refinery)
  • Thermal Oxidiser (Queensland Alumina Refinery)

No application is too big or too small. We have a team of Electrical, Mechanical & Piping Engineers available for consultation or on-site support.

Packaged Substations

Packaged Substations

Packaged Substations

Modular Packaged Substations (MPS) save considerable time and cost compared to on-site fabrication. Fully tested Motor Control Centers (MCCs), and Control and Distribution Centers (CDCs) can be fabricated quickly and fully factory tested before delivery to site.
Pre-installed cable raceway sections and drop-boxes attached to the substation support frame also save time on site, and ensure cable routes and bending radius issues are dealt with before cables are pulled.

Helmet Cameras

Helmet Camera

Commissioning Using Helmet Cameras

Travel restrictions due to Covid-19 is making commissioning and factory testing more difficult, so Logitech Engineering are now using high resolution Helmet Cameras to stream live data to clients and vendors. In July 2020, Logitech successfully completed the Factory Test and Commissioning of a new Thermal Oxidiser at Queensland Alumina which was manufactured in Victoria and commissioned in Gladstone QLD.

Hands-free operation (100% voice activated) even in very noisy environments up to 105dB, with no loss of signal strength or performance.
