The industrially-standard items are clearly laid out, screw-fitted into an aluminium panel. The symbols on the panel show the correct graphical representation as well as the DIN and standard designations of the items concerned. This instructional kit is used for demonstration and information purposes. No provision is made for conducting exercises or experiments. The kit is clearly laid out on a plastic tray. The well-structured instructional material enhances the informational value of the kit.

The heat and light sources, instruments, filters and plates are mounted on an aluminium track with graduated scale, which is designed to stand on the benchtop and connect to the Heat Transfer Service Unit without the need for tools.
A heat source with radiometer and a light source with light meter are used where appropriate to demonstrate the principles.
A small-scale accessory designed to introduce students to the basic laws of radiant heat transfer and radiant heat exchange.
The light source consists of a 40 Watt light bulb (operating at 24V DC maximum) mounted inside a housing with a glass diffuser.
The heat source consists of a flat circular plate 100mm in diameter which incorporates a 216 Watt electric heating element (operating at at 24V DC maximum).
A comprehensive instruction manual is supplied.
The unit consists of four different types of pumps namely-centrifugal, turbine, reciprocating and axial flow pump, a common storage tank, and measuring instruments. Each pump is driven by a motor dynamometer for measuring TRUE pump input power. Multi Pump Test Set, Motor Dynamometer is a self contained set for studying the characteristics for various types of pumps. Speed control is by an inverter. The unit is floor standing with removeable supports. By manipulating flow control valves and a selector switch, each pump can be operated individually.

Pasteurising temperatures and holding times are easily adjusted, allowing the effectiveness of the product treatment to be investigated. When correctly operated, cleaned and sterilised can produce a correctly treated and pasteurised product. However it is not intended that this apparatus be used to manufacture products for human consumption. Although primarily designed for use with milk, other food liquids can be pasteurised providing that their solids content is not too high.
The Laboratory Pasteuriser accurately reproduces in miniature the industrial High Temperature Short Time process. Nominal throughput is only 10 litres/ hour.
The three stage plate heat exchanger of the achieves these parameters by
Transfers heat from the treated product to the feed liquid. Full instrumentation and controls are provided to regulate heating water temperature and also feed pump speed which in turn regulates holding time. This provides dual benefits in reducing the energy required to reach the pasteurising temperature and in reducing the cooling required. An optional Chilled Water Circulator is available.
Heating the process liquid with hot water prior to its entry into the holding tube and then by
Cooling with cold water to storage temperature. An intermediate heat exchanger.
Mahler Calorimeter For Determining Heat Of Combustion allows to measure the heat from combustion of several substances such as both liquid and solid hydrocarbon fuels with low and high volatility.

The air is next passed through a filter of the type used in commercial systems and then cooled by the evaporation of refrigerant in a built-in condensing refrigeration unit. A variable delivery fan supplies metered air to a pre-treatment plenum chamber where it can be heated and humidified to a variable and measured extent. Any moisture condensed from the air at this stage is collected in a measuring cylinder. The refrigerant compressor is a single cylinder unit driven by an AC motor. The air then passes through a reheating chamber with a measurable heat input facility before discharge to atmosphere. The design of the unit is such as to ensure that all readings provided by the instrument relate to a proper homogeneous air flow.
Special Features:
The refrigerator condenser is adequate for use under tropical conditions, i.e. with cooling water up to 32ºC (90ºF).
Temperature readings from a total of 16 remote reading thermocouple instruments are provided by the Cussons multi-point, multi-range, thermometer. Safety in use Interlocked controls make it impossible to generate steam from the humidifier or to run either the air flow preheater or the air reheater without first turning on the air flow blower. However, water in the steam generator can be heated to 90ºC before starting the blower, in order to save class time. The level of water in the steam generator is shown by a sight glass.
The temperature reading point operative at any one time is shown by an indicator light on the mimic diagram.
The transmissioncan be turned easily both from the drive and also from the output side. With the 5th generation of automatic transmissions, the following is achieved: high shifting comfort, light weight construction, fuel savings and increased driving enjoyment.
The following are visible:
All 7 hydraulic couplings
Range selector can be shifted
Solenoid valves and many small construction parts
Parking lock
