Easy to Operate
Espar heaters operate as miniature furnaces independent of the engine, utilizing the units own diesel fuel and batteries to produce heat.
Efficient
Hydronic units heat the coolant, then circulate it to warm the engine and heat exchangers to near operating temp and can be sized to provide auxiliary heat for other critical fluids. Espar air heaters heat air directly and circulate air to applicable compartments.
E-Work HYDRONIC air heaters can provide ample heat to the cab, mobile work stations, crew shelters, all without idling the engine.
Productive
Using timer controls, heaters can be switched on to begin engine pre-heating at preset intervals, allowing operators to go directly to work upon arrival.
