Engine Heaters

Engine heaters keep diesel and gas engines warm and ready to start in cold conditions, maintaining coolant and oil temperature to reduce engine wear, cut warm-up time and lower start-up emissions. This range covers coolant heaters (thermosiphon and forced-circulation), lube-oil and industrial immersion heaters, in-block (core-plug) heaters, battery warmers, and the thermostats and control systems that complete the heating system.
Engineered for standby generators, marine engines, compressors, locomotives and industrial plant, these HOTSTART engine pre-heating products are available in weathertight and hazardous-location models across a wide range of voltages, wattages and fittings to suit almost any application.
