Abrégé

A mobile letdown station for regulating a supply of natural gas includes a wheeled trailer and a regulating system onboard the trailer. The regulating system includes a flow path with a pilot operated pressure regulator, a heat exchanger for transferring heat from a heater to the natural gas, an electronic thermostatic controller for controlling the heat output of the heater, and a thermopile for converting heat from the heater to electrical power for the thermostatic controller, such that the regulating system is operable without any external electrical power. The regulating system has a pair of parallel flow paths, each having a pressure regulator, for redundancy in the regulating system. The flow path of the regulating system is disposed in an enclosed compartment of the trailer, along a periphery of a floor of the compartment such that a central portion of the floor is unoccupied by the flow path.
