The blast freezer and fluid bed sections are contained, along with the fan and evaporator, inside an insulated cabinet. Inside the cabinet, a fan with adjustable impeller transports air from the interior of the cabinet into the freezer ducting and through the evaporator tube bank where it transfers heat to the refrigerant. Access doors to both sections are fitted with observation windows and an electrically heated surround to prevent the doors from freezing in the closed position.
The blast freezer section contains 5 trays on to which the food samples to be frozen are placed. The air, now reduced in temperature, passes trought he tray section which can be observed through a removeable perspex panel. It then changes direction and passes vertically up through the fluid bed section, back into the cabinet space where it is again circulated by the fan.
There is a facility for a suitable anemometer to be inserted into the ducting to allow the air speed to be measured. There is a facility for thermocouple sensor leads to pass into the ducting and through the cabinet wall so that freezing temperatures and rates can be monitored externally.
The system includes a dynamometer with a control and instrumentation panel. On the test bed, an engine selected among the engines in widespread use is mounted. Computerized Automotive Engine Test Bed allows to carry out a vast selection of tests on petrol and diesel engines, with a power output of up to 80 kW. Other engines not listed in this catalogue can be supplied on request. The system is supplied with manuals, which describe all parts of the trainer, the installation and utilization procedures, as well as many exercises with the relative results.

The experimental unit generates cold and hot air with the aid of ordinary compressed air. A vortex cooling device does not have any moving parts, is maintenance-free and immediately ready for operation. The vortex cooling device is used for the convective cooling of high-speed tools, the air conditioning of protection suits and the cooling of switch cabinets. The central element of the experimental unit is a vortex cooling device also known as a vortex tube. In the vortex tube the tangentially incoming compressed air is moved in rapid rotation. It is particularly suited for use in explosive environments. One benefit here is that the vortex cooling device does not require an electric power supply. This creates a cold and hot air flow in the vortex tube which leaves the vortex tube at opposite ends.

ASR then shifts from differential brake controlto engine control to reduce engine power. The ASR activates the differential brake valveto control the brake cylinder, and the engines driving torque is applied to the braked wheel. The ECU activates the ASR when the wheels rotation exceeds the slip threshold.
