Engine Saver® - Model 550
Providing Protection for Thousands of Engines Worldwide Since 1980
This is Engine Protection that works! Thousands in service worldwide, fully supported with on-site installation, spare parts and test equipment.
The Engine Saver® monitors a combination of pressure, temperature and RPM on 8, 12 and 16 cylinder diesel or gas engines, and detects the early signs of trouble before damage occurs - long before an attentive operator could detect it on the gauges - and without false alarms. Most common faults go undetected until they cause consequential damage or engine destruction
