Mini-Ran

Eskaders fire-tube boilers (Mini-Gnom, Mini-Neptun, Neptun, Mini-Ran, Ran) is designed to suit model steam boats in wich the center of gravity is wanted as low as possible. The boilers has a fire tube in the length direction which is crossed by several tubes. This construction gives a very rapid vaporization. To isolate the boiler a layer of Rock-wool is recommended along with a layer of soft aluminium plate or wood strips and some brass tape to keep the isolation in place. Because the flame is completely surrounded by the boiler, only a thin layer of isolation is required for the hull around the boiler. The Mini-Ran is suitable for steam engines like the 10-V, 10-H, Nr. 8, Nr. 7-A, Beam engine, Victoria, James Coombes steam engine, Williamsons steam engine and can be used in smaller steam boats up to the length of 53 3/16" (135 cm).
