Hotstart’s New Engine Heater

Hotstart unveiled its newest engine heater at PowerGen International 2019. The new EVRHEAT Series 20 forced circulation engine heater targets generator set applications in the United States and Canada.

The EVR20 is designed to preheat and maintain engine temperature in generators up to 20 L displacement while in standby mode. A new, at-a-glance operator display shows current status of the heater and users can see that power is on, the element is energized, and the pump is circulating heated coolant. Integrated controls and sensors monitor the status of the heater and coolant and if an air pocket or other fault is detected, the heater shuts down, allowing the user to resolve the fault and reset the heater.

Installation is simplified with an adjustable 180° swivel inlet hose barb, accommodating plumbing requirements in confined areas and allowing for easier field retrofits, the company said. The EVR20 is engineered to apply heating power precisely, adjusting the output wattage in response to fluid temperature changes as little as 1 °F. This, the company said, results in more uniform heat to the engine and eliminates nuisance low temperature alarms. In addition, its efficient operation, provides up to 45% energy savings over standard thermosiphon heaters, the company said.

Hotstart said it will start taking pre-orders for the EVRHEAT Series 20 starting Dec. 1 and will ship product to customers in the US and Canada starting in January 2020.
