REPLACE YOUR OBSOLESCENT HEATERS WITH A
​WATLOW SOLUTION FROM NUSOURCE, LLC 

JACKET WATER HEATER
This immersion heater is mounted in the standpipe or separate heating tank.  When the engine is in standby mode, the thermostatically controlled heater is energized. The heated coolant flows through the engine warming the cylinders, cylinder heads, and other water-cooled engine components to minimize the high stress and increased wear when the engine is cold.

​LUBE OIL HEATER (IMMERSION)
This thermostatically controlled immersion heater is placed either in the lube oil sump or in a bypass tank. The heater maintains the lubricating oil at or near the generator’s normal operating temperature. 
NuSource can prepare a new Certified Design Specification and supporting ASME Code Evaluations that justify Watlow heaters to replace your obsolete heaters.
