Abstract
The invention consists of an outer jacket surrounding and spaced from an inner tank to create an insulated space therebetween. The inner tank closely conforms to the outer jacket such that the insulation chamber is substantially uniform and the capacity of the inner tank is increased. An insulated support assembly that extends into the inner tank allows communication between the exterior of the vessel and the inner tank for pipes, pressure gauges and the like. The support assembly allows for a long insulated path without reducing the capacity of the tank to the same extent as the prior art devices.
