The aluminium structure is covered by a painted steel panel.
The unit for impact testing with the Charpy and the Izod pendulums is mounted on an aluminum structure that provides the device great rigidity.
A robust support pillar fixes to a suitable table or bench(not supplied) with a low natural frequency. The pillar holds a cantilever that holds a model four-cylinder engine.
A bench- mounting model four-cylinder engine that shows primary and secondary forces and moments in reciprocating masses and how to balance them. The model engine has a crankshaft, connecting rods, bushes , pistons and a cylinder block. A separate Control and Instrumentation Unit (included) controls a motor that turns the engine crankshaft. This product is an excellent follow-on from the Static and Dynamic Balancing equipment.
Experiments:
Primary and secondary forces and moments for different crank settings.
Comparing calculated forces and moments with actual results.
The effect of adding additional mass to one or more pistons for any chosen crank setting.
Primary and secondary forces and moments in popular engine configurations - one, two and four cylinder.

For the sake of safety, the system normally operates at three-phase 220V. Different line voltages can be adjusted by system transformer.
The system is supported within a stainless steel framework and requires only connection to suitable steam, electrical and water services for operation.
The component parts of the industrial process have been scaled down, feed tank, vapour / liquid separator, condenser, concentrate tank, condensate tank, CIP pump and vacuum pump, all manufactured from hygienic materials such as stainless steel, PTFE and glass. The single tube-in-jacket evaporator replicates industrial units which often contain scores of much longer tubes within the steam space.
Only 0.65m² of floor space is required to install the evaporator and it has been designed to fit easily into a room of standard height.
The Pensky Martens Flash Point Apparatus allows for the determination of the flash point up to 370 °C of drying oils, fuel oils, lube oils, suspensions of solids, solvent-type waxes, liquids that tend to form a surface film and other liquids.

The refrigeration circuitry includes a water cooled condenser complete with isolating valves, manual expansion valve, evaporator, variable area flowmeter for mass flow of refrigerant, filter/drier unit, sight glass and over pressure cut-out for unit protection. The unit is designed to use Tetrafluoroethane as the refrigerant with a twin cylinder reciprocating compressor, belt driven by the variable speed dynamometer.
The evaporator coil is mounted in an electrically stirred water/glycol mixture contained in a thermally insulated, stainless steel tank. The water/ glycol mixture is protected from over temperature conditions by a thermostat should the heater should be left on when the compressor is not circulating refrigerant. Heating of this water/glycol mix is infinitely variable enabling balanced experimental conditions over a wide range of temperatures to be obtained.
