A heat transfer fluid filtration system that filters contaminants down to 10 microns specifically developed for hot and warm mix asphalt and associated plants is now available from Liquid Process Systems, Inc. 

  Easy to integrate within a new or existing facility, the patented Vector Series Model VB10C Thermal Fluid Filtration System from Liquid Process Systems continuously filters contaminants on a side stream basis down to 10 microns to keep fluids clean for higher heat transfer and plant efficiency, longer fluid life and minimum maintenance downtime. System flow and pressure available from the plant process is used to re-circulate hot oil or thermal fluid from the pump discharge through the filter. Clean fluid is then returned to the suction side of the pump. 

  The system can withstand up to 150 psig (10.5 bar) of pressure and temperature up to 650°F (345°C). Flow rate and cleaning capacity of the Model VB10C is up to 15 gallons per minute (114 liters per minute) or over 900 gallons per hour (3,405 liters per hour). This is enough cleaning capacity to filter the entire volume of a smaller system several times in a typical day. As a result, the useful life of the hot oil is increased since it is filtered and remains clean to last longer. Fouling and carbon sludge build-up are reduced, unscheduled maintenance is minimized and heat transfer efficiency is increased. With cleaner fluid,
wear on moving parts such as process pump mechanical seals, impellers and valves are significantly reduced. In fact, filtering hot oil normally results in a three fold increase in pump life, according to Liquid Process Systems.

  “Not filtering the hot oil or thermal fluid at your plant could disrupt your operation at the most inconvenient times, for example when a line of asphalt trucks are ready to load and you can’t get up to temperature or working overtime nights and weekends to repair pumps and clean out clogged lines,” noted Judy Shums, President of Liquid Process Systems. “Our system is customized for quick and easy installation in your plant with only a minimum time disruption.  All we have to do is make the two inlet and outlet connections by choosing either threaded, socket weld or flanged. Investment is minimal and payback is quick depending on total volume filtered. Disposable elements are cheap and easy to replace.”
  Shums added that we wouldn’t run our cars without an oil filter so why run your plant without one. Contaminants that can cause havoc to any operation can be easily and efficiently removed to assure a ready supply of asphalt from hot and warm mix asphalt plants for road surfacing, roofing materials, aggregate producers and others.
Vector System Explained

The Vector Series Model VB10C uses economical glass-fiber wound cartridges that have excellent dirt holding capacities, are easy to change and are disposable. Life of the filter element is approximately 6 to 10 weeks, depending on condition of the fluid. Regular filter change outs can also be scheduled if preferred by maintenance and operations personnel.

  As an option, an electronic filter condition monitoring system is available that displays a flashing light or communicates directly with the plant’s computer monitoring system to notify the plant operator when filter cartridge needs replacing or when it is completely clogged. Shums noted that initially more frequent change outs of the filter can be expected because as the fluids become cleaner, change outs become much less frequent.

  Fluid is drawn into the filter unit by tapping the existing piping that diverts a small percentage (usually about 10%) through the filter unit. The fluid is then cleaned and re-introduced down stream or to the suction side of the existing recirculation pumping system.
