A flywheel mounted in ball bearings is placed in motion by a weight attached to a pulley. The inertia of the flywheel can be determined from the fall time of the weight. Using the basic experiments on uniformly accelerated angular motion can be performed. The unit is intended for wall mounting. Due to the clear, robust construction the unit is excellently suited to student experiments.

Secondary Loss Of Load equipment is suitable for the study of losses and it includes straight sections of piping for the study of primary loss that could occur in the system. All pressure connections have double sealed quick couplings; the system includes also a differential water manometer and a digital differential pressure gauge for measuring the resulting pressure. The equipment includes also other elements such as elbows of different diameters 90 and 45, tees, widening, narrowing, various types of valves (as ball, gate, membrane, backstop) with pressure taps upstream and downstream arranged in order to determine loss load produced with different flow rates.

The Stirling Cycle Hot Air Engine Vertical Cylinders unit is for demonstration of stirling cycle hot air engine principles. Instruments are provided for measurement of input power, and output power. The advantage of this design is the ability to bring the engine to operating condition in a short time.The engine consists of two vertical stainless steel cylinders. The first cylinder is to generate hot air using a heater. Power to the heater can be varied. The second cylinder is to generate a mechanical power using hot air from the first cylinder. Both cylinders are attached to a common shaft, with a suitable flywheel.
Experiments:
Output and efficiency vs speed for a given input power.
Torque vs speed for a given input power.
