Large Stirling Engine Black (ASSEMBLED)



           


The Kontax Low Temperature Differential Stirling Engine shows with one spin of the flywheel a clean and simple way of converting thermal energy into motion.

This engine will operate from many heat sources, including hot water, computer monitor, TV and the human hand. As long as there is a small difference in temperature between the upper and lower plates this engine will run.

Every engine has been tested to run from the heat of a hand.

This engine has been meticulously engineered. As any Stirling Engine enthusiast knows, friction is a major problem with small low temperature differential engines, therefore all potential sources of friction in this engine have been eliminated. Another common problem with LTD Stirlings is heat transfer directly between the plates. Again, all possible routes for heat to transfer directly between the plates have been eliminated.

Based on the pioneering work done by Dr Senft at the University of Wisconsin, this model has been designed, manufactured and hand built in England.

A large number of schools and universities have bought our engines for educational use, the transparent chamber wall and cylinder make it easy to explain the Stirling cycle to students. Many of our engines have been kept running for years on top of coffee machines, computers, fax machines, etc. in shops, kitchens and offices all over the world. Many customers take great delight in running our engines on a bowl of ice or snow, where the engine happily runs, but backwards.

Engine features:-

  • Low-profile heat insulated chamber pillars, giving a flat underside and therefore good contact with your heat source
  • Both connecting rods are positively located using low friction PEEK and stainless steel screws
  • All airtight seals are made with high strength precision screw threads and nitrile O rings
  • Ultra low friction demagnetised and de-greased bearings, NO lubrication required
  • Fully CNC machined, giving crisp, clean and tidy edges all over
  • Engine parts ultrasonically cleaned before hand assembly

Engine materials:-

  • Stainless steel connecting rods and ball-race bearings
  • Micron precision Borosilicate glass cylinder
  • Micron precision Graphite power piston
  • Aluminium main pillar, hub and spokes
  • Brass chamber pillars and flywheel rim
  • Brass gland and cylinder holder

Engine dimensions:-

  • Chamber plates - 167mm diameter, 2.5mm thick
  • Displacer - 130mm diameter, 12mm thick
  • Flywheel - 140mm diameter, 4mm thick
  • Power piston - 18mm diameter
