ABSTRACT:
Separating device for separating the liquid components of a liquid mixture comprising an annular coalescing medium (84) for causing the liquid component to be removed from the mixture to coalesce into droplets, and a conical separating medium (102) tapering toward a liquid collecting sump (98). A heating element (46) heats the liquid mixture when the temperature of the mixture is below a predetermined temperature. An open, fibrous batt of filtering material (100) circumscribes the coalescing medium (84) to collect wax crystals which form during cold temperature conditions. A relief valve (108) permits liquid to bypass the separating medium (102) when the pressure differential across the separating medium (102) exceeds a predetermined amount. Accordingly, initial flow through the separating device is established, permitting the heater to heat the liquid to a temperature above that at which wax crystals form.
