Re-manufacturing an alternator
Trains are fitted with sophisticated heating, ventilation and air conditioning (HVAC) systems to keep temperature and air quality in the passenger coaches optimal. Power for running these systems is supplied by an alternator which converts mechanical energy into electrical energy.
This device is mounted under the train carriage and fulfils its task under heavy circumstances. As alternators are expensive, re-manufacturing at the end of their life time is a good method in getting them in as new condition at significantly lower costs. Manufacturer Elite KL Ltd. from Tamworth (UK) also recognizes an increasing demand from railway operators for re-manufactured alternators which they once supplied new.
