HOTSTART’s HOTflowTM heating system (CTM model) is a complete coolant preheater with thermostat, pump and all required controls. The CSM model heats engines ranging in size from 15L-100L displacement. Forced circulation of the coolant delivers uniform heating throughout the entire engine, extends element life and offers a significant reduction in electrical consumption.
HOTflowTM model CSM was developed to preheat diesel and gas engines for stationary land power, marine, large mining and construction equipment.
