Abstract

A mobile dehydration system that is operable to remove water from a supply of fluid, such as hydraulic fluid. The mobile dehydration system includes a fluid pump that draws the supply of hydraulic fluid from a storage tank. The flow of hydraulic fluid passes through a fluid heater that elevates the temperature of the hydraulic fluid. The fluid heater includes at least one flow restricting orifice that reduces the pressure of the flow of hydraulic fluid, thereby elevating the temperature of the hydraulic fluid. The outlet of the fluid heater is connected to a dehydrator that removes water from the flow of hydraulic fluid. A fluid feedback line is connected between the outlet of the fluid heater and the inlet of the fluid pump to return a portion of the hydraulic fluid flow when the flow rate through the dehydrator is less than the flow rate from the fluid pump.
