This kit will equip a JD4045 generator (John Deere 4045 engine) with the Ventech LHG Thermal Load Management System (TLMS). The LHG-TLMS exercises the engine by automatically applying a mechanical load to maintain the ideal operating load and temperature when the electrical load drops below a predetermined threshold for a protracted period. This better protects both the engine and the exhaust after-treatment system.


The LHGTLMS is available as part of an installation kit tailored for each specific generator application.
