Abstract

A used lubricating oil reclamation apparatus in which filters, heat exchangers, a vaporizer unit, pumps and other necessary equipment are all contained in a wheeled cabinet. The oil to be reclaimed is pumped through a warming heat exchanger, a first filter, a vaporizer unit, and further filters, after which appropriate additives are mixed into the decontaminated oil in a mixing tank. A vacuum is maintained on the vaporizer unit to exhaust the vapours from it via the heat exchanger and a condensate tank.
