Maintaining a highly accurate and repeatable dosage, our Chemical Injection Units (CIUs) can deliver a wide range of chemicals either at a fixed pressure or to a required flow rate with closed loop feedback. This can be vital to support contaminant removal, enhanced recovery techniques and hydrocarbon conditioning - helping to protect your assets and improve performance.
