The ChemStar is a recent addition to the Calfrac fleet that hauls, handles and transfers bulk chemicals. Its typical application is on larger fracturing jobs where larger volumes of chemistries are required. The ChemStar features three compartments, two with capacity of 1,500 US gallons and one with capacity of 1,000 US gallons. The chemical additive pumps are microprocessor-controlled to ensure very precise chemical balances on-site. The ChemStar is able to transport and handle larger volumes and does not require chemical transfer totes.
