Abstract

There is disclosed a device for supplying a flow of heated air for scavenging the interior of emptied liquid-containing tanks and comprising an electrically driven fan (5, 6), an air filter (11) fitted to an inlet of the fan, ducting (12) connecting an outlet from the fan to an inlet of a heating chamber (14) which houses one of more electrical heating elements (30), ducting (19) connecting an outlet from the heating chamber (14) to an inlet (20) of a hose reel (21), a hose wound on the reel and connected to the hose reel inlet (20), a thermostat (54) in the air path downstream of the heating elements (30), a connection box (40) for the heating elements (30) which is spaced from the heating chamber (14), and guide means in the form of tubes (36, 38) enclosing ends of the heating elements (30) and guiding these from the heating chamber (14) to the connection box (40). A control box (50) houses electrical controls for the fan and the heating elements; and the electric motor (6), the connection box (40), the control box (50) and all the connections thereto are flameproof. A device according to the invention is therefore particularly useful for scavenging fuel tanks which have contained volatile material, so as to deliver air at a temperature which is sufficiently low that there is no danger of ignition of any residual volatile elements, while being sufficiently high to promote evaporation and therefore clearance of less volatile or non-volatile material, such as water.
