The EVRHEAT Series 20 has been designed and built with efficiency, versatility, and reliability in mind. Indicator lights on the operator display show current heater operation and temperature status, so you can be sure your engine is always ready to start. At-a-glance, users can see power is on, the element is energized, and the pump is circulating heated coolant. The integrated controls and sensors monitor the status of the heater and coolant; if an air pocket or other fault is detected, the heater deactivates power allowing for users to safely resolve the fault and reset the heater.
Installation of the EVR20 is simplified with an adjustable 180° swivel inlet hose barb, accommodating plumbing requirements in confined areas and allowing for easier field retrofits. The EVR20 applies heating power precisely, adjusting the output wattage in response to fluid temperature changes as little as 1 °F. This results in more uniform heat to the engine and eliminates nuisance low temperature alarms. When compared to thermosiphon alternatives, the EVR20 is more efficient in its operation, providing up to 45% energy savings over standard thermosiphon heaters.
