I have no knowledge of what these devices do or where they're used for but by name it ranks up there with evaporative condenser.

I clicked on a few of them. They don't know what they do either.

The Racor ECHTM Engine Coolant Heater Series benefits your engine all year long. Regardless of ambient temperature, pre-heating prolongs the life of your engine. The fact is, 90 percent of engine wear is due to low water jacket temperature. Racor ECHTM heaters reduce maintenance and service demands by reducing wear and lengthening the time between oil changes. That can mean more time between overhauls. Pre-heating the coolant keeps the engine at operating temperatures. It eliminates needless idling and reduces noise and air pollution.

Racor ECHTM tank-type coolant heaters maintain an engine's operating temperature during down-time and serve as an excellent cold weather starting aid. From small, 500 watt durable plastic tank-type coolant heaters to large capacity tank-type coolant systems of 5,000 watts.

The Racor ECHTM tank-type coolant heaters operate using the thermo siphon circulation principle. Heated coolant is returned to the engine as colder coolant is drawn into the heater.

By utilizing standard alternating current (AC) from the customer-supplied source, they heat and maintain the engine coolant at a pre-determined temperature range. This warm coolant helps keep the engine ready for instant operation. Racor ECHTM tanktype coolant heaters are mounted off the engine for long life and increased wattage output.

Racor ECH Tank-tupe coolant heaters can meet all diesel generator heating requirements regardless of engine size.

Weather-tight construction.
All ECH components carry the CSA (Canadian Standards Association) approval and CE (European Union) mark.
Thermostatic controls ensure proper and efficient operation of the ECHTM tank-type coolant heaters.


NOTE: Not for use as fuel heaters.
