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.

The thermal conductivity can be calculated from the temperature difference between the hot and cold end and the heating capacity. The housing contains the vacuum pump and the digital displays. The measured values can be read on digital displays. In this experimental unit, a metal test bar is clamped between a heater and a Peltier element as the cooler. In this way errors due to convection can be ignored and all the heat must flow through the test bar. The complete arrangement is under an evacuated bell jar. At the same time, the measured values can also be transmitted directly to a PC via USB. The data acquisition software is included.

The mechanism able to transform circular movement into reciprocating movement. The unit is assembled in an anodized aluminum profile structure, with steel painted panel. It is made of aluminium and consists of a rotary element (graduated disk), called crank, connected to a rigid bar, called connecting rod. The rotation motion of a crank or crankshaft causes a rectilinear reciprocating motion of a piston or plunger. When rotating the crank, the connecting rod moves back and forward.
It is a reversible system through which the connecting rod can be displaced by turning the crank and the other way round. If the connecting rod generates the input motion (as a piston in a car's engine does), the crank is obliged to rotate.
This mechanism is a combination of an inversion of the slider-crank chain and slider block.
They have the curved shape, of an arch, which can be circular or parabolic. Arches are the structures, which look somewhat different from the columns and beam.

A set of thirteen graduated tubes show the oil pressure across and along the film under the pad. The bench-mounting unit has an aluminium plate (pad) mounted above a continuous loop flat belt. This creates a pressurised film of oil between the pad and the belt. The belt runs in an oil reservoir to provide a continuous supply of oil under the pad.
Students vary the belt speed to find the relationship between sliding speed, oil viscosity and pressure distribution. Included is a variable speed control to control the speed of the motor that turns the belt.
Experiments:
Pressure distributions in a tilting pad bearing.
The relationship between pressure and the film thickness at the trailing edge of the pad.
Influence of sliding speed and viscosity on the pressure distribution in the bearing and comparison with calculations based on Reynolds equation.
