Knelson has broken ground on a 15000ftІ (1100mІ) plant expansion at their Langley B.C. manufacturing facility. Once complete, this expansion will increase total plant, office and research laboratory space to in excess of 35,000ftІ (3200mІ). Justification for the expansion was driven by strong demand for existing Knelson products in addition to two new products the company plans to launch during the year. This includes a new line of patented continuous variable-discharge (CVD) concentrators.
