Kontax KS90 Aluminium Stirling Engine Kit in Black
The original and best Low Temperature Stirling Engine in Kit Form, MADE IN UK
The Kontax KS90 Low Temperature Stirling Engine features anodised aluminium chamber plates, super-lightweight flywheel spokes and a solid brass rim, all styled in an elegant and efficient manner. The engine is designed in a gamma configuration, with the power piston and displacer disc connected at a 90° offset on either end of the central axle. Often copied but never equalled, the classic KS90 has remained at the top of Low Temperature Stirling Engine tree for over 15 years.
How does it work?
Stirling engines work by cyclically heating and cooling the air inside the main chamber. As the air heats up it expands, and as it cools down it contracts. This expansion and contraction drives a small piston which in turn drives the flywheel. The clever thing about Stirling engines is that the mechanism for cycling the heating and cooling of the air is built into the engine in the form of the displacer, which is driven by the flywheel and crank arrangement and moves the air from the warm side to the cool side and back again over and over.
The Stirling engine is named after its inventor, Rev. Robert Stirling, who patented his idea in 1816.
