D21: Elegant Beauty in Red and Black
The D21 steam engine is a double-acting fixed brass cylinder power engine.
The technical specifications are similar to those of the D 20, but the special color scheme gives this machine a particularly elegant finish:
All metal parts are painted in black and red. The flywheel has also been painted red. This special machine is rounded off by highly polished brass parts.
A technical feature is the built-in feed water pump, which is only found in the D21 steam engine within the Wilesco range.
Water pump allows refilling during operation
This water pump allows the boiler to be refilled with water during the ongoing operation of the steam engine. The condensate is discharged into a condensate water basin below the chimney and causes the chimney to steam. The steam exit can be manually controlled by means of a steam stop valve in the D21. The power engine is driven by our dry fuel Witabs, one charge of Witabs is enough for about 10-15 minutes of steam fun.
It takes about 5 minutes from the first lighting of the steam engine for sufficient steam pressure to build up and the engine to be set in motion. The D21 then has enough power to drive several drive models. So you can follow the conversion of heat into motion energy in a very visual way. It is also especially fun to generate electricity and light by connecting the separately available parts Dynamo M66 or Dynamo with Lamp M66/2!
