The filtration capacity of TOR-5 is intentionally moderate, because it is designed for continuous conditioning, not bulk oil processing. In typical configurations, the circulation flow rate is on the order of 10-50 liters per hour, depending on the pump and cartridge set used. This low flow is sufficient to control moisture and contaminants over time without disturbing transformer hydraulics. TOR-5 is not meant to replace mobile oil treatment units, but to stabilize oil quality gradually during normal operation.
