Glycol Filtration

Heat transfer fluids, such as propylene glycol, ethylene glycol and triethylene glycol (TEG) often become contaminated with particles.  Particulate contamination is detrimental to glycol systems.  It is important to maintain these fluids.  Particulate contamination in glycol systems accelerates component wear and reduces the heat transfer capability thus reducing system efficiency.  Hard particles moving at high velocities cause excessive wear on pumps, seals and other components.  These high velocity wear particles create new particles growing the problem exponentially.  Soft particles and/or semi-solid particles plate out on pipe walls and heat exchangers reducing their efficiency.

With the continuous creation of new particles from the existing particle contaminants, the problem can grow exponentially. These contaminants or debris in the heat transfer fluid loop can clog the heat exchanger and pipes requiring replacement of capital equipment.

We can offer inline and side stream (kidney loop) filtration that can filter down 10 nanometers.  Our high-capacity filters will help maintain the health of the heat transfer fluids and increase the service life of the system. We offer filters with various material of construction, pressure rating and flow rate capabilities.

We offer fluid testing with different filters and custom design filtration solutions to customer specification. We  design and build filter skids with multilevel filtration, gauges, and valves.
