Introduction
The 810 is designed to train students in the operation, fault finding, maintenance and repair of automotive air conditioning systems.
It comprises a complete automotive air conditioning system on an alloy frame suitable for bench mounting. The unit operates on R134a refrigerant used in most current vehicle air conditioning systems and connections are provided to allow the use of standard R134a manifold gauges.
Description
Model 810 is one of a range of trainers designed to provide practical training in the fields of Refrigeration and Air Conditioning.
Each trainer has been carefully designed to provide instruction in specific topic areas that trainees are required to study as part of most Refrigeration and Air Conditioning courses.
The compressor is driven by a synchronous AC electric motor and the complete unit has an internal Residual Current Device for additional operator safety. Apart from the drive motor all other controls are 12V as used in automotive air conditioning systems.
Temperature control is by an adjustable electronic thermostat and the evaporator has three fan speeds to show the effect of air velocity and varying load on the system
Four common faults can be demonstrated –
Blocked Thermostatic Expansion Valve
Blocked Drier
Compressor Fault
Poor Condensing
A standard Student Tool Kit and Test and Service Equipment Package are available as optional items.
Further details available on request.
