Nathan DeMartino, president of Dexter Biodiesel Solutions in Pearland, Texas, said his company recently sold its first BCC900 Cold Clear unit to Keystone BioFuels, a 20 MMgy facility in Shiremanestown, Pa., and said that it is the largest unit sold "anywhere in the world," and the largest install to date.

The larger models consist of completely different housing and filter systems than the smaller counterparts. They filter 45 gallons per minute of biodiesel fuel and can process 120,000 gallons to 200,000 gallons before the filters need to be changed.

This shows blenders and other high-throughput producers that the unit can handle their loads, DeMartino told Biodiesel Magazine. "I'm really excited about blenders and the market that is there for this system," he said. "This installation at a 20 MMgy per year plant demonstrates to blenders that these larger units can be used to lead to better cloud point, pour point, cold filter plugging point and oxidation stability."

Keystone BioFuels will use the Cold Clear unit as a quality control measure to ensure that the biodiesel they produce is consistently below the ASTM cold soak standard for biodiesel, which will "help them achieve the coveted BQ9000 status," DeMartino said.
