HOTSTART SB Series engine heaters deliver a compact, heavy-duty solution for aftermarket diesel and gas engine preheating. Built with pressure die-cast aluminum tanks, these coolant heaters withstand harsh environments while providing reliable engine temperature control. The SB Series includes a built-in high-limit safety thermostat, an optional flow-through control thermostat, an attached power cord, and multiple voltage and wattage options for true plug-and-play installation.
Installed externally on the engine block, HOTSTART SB thermosiphon heaters use natural convection to circulate heated coolant without a pump. This passive heating design allows easy installation across a wide range of engines without requiring a specific water jacket connection, making the SB Series a versatile and efficient engine heating solution.
By preheating diesel and gas engines, the SB Series ensures faster starts, quicker load acceptance, reduced engine wear, and improved reliability. Industries such as fleet operations, mining, construction, data centers, and hospitals rely on HOTSTART SB engine heaters to protect critical equipment, reduce downtime, and maximize engine performance in cold or standby conditions.
