At a glance, users can monitor the current status of the heater through indicator lights, ensuring engines remain within their optimal temperature range for smooth startups and reduced emissions.

Troubleshooting is simplified with the EVRHEAT Series 20. In case of a fault, the system promptly detects and deactivates to prevent any damage, minimizing heater downtime, repair expenses, and warranty claims. Clear fault indicators on the display assist users in swiftly identifying and resolving issues in the field.

The EVRHEAT Series 20 features quick response controls, employing solid-state technology to react to fluid temperature changes as small as 1 °F. This ensures enhanced temperature consistency and eliminates bothersome low-temperature alarms.

Installation becomes effortless with the EVR20, thanks to its adjustable 180° swivel inlet hose barb. This design accommodates plumbing requirements in tight spaces, allowing for easier field retrofits.

The combination of solid-state temperature controls and a debris-resistant forced circulation pump results in an exceptionally durable engine heating solution. It boasts up to 45% greater efficiency compared to standard thermosiphon (TPS) heaters, leading to a lower total cost of ownership.

Efficiency and performance are critical in engine heating systems. While delivering essential benefits to organizations relying on onsite power generation, inefficient solutions can drain resources through excessive electrical costs and frequent repairs. Comparing the Hotstart EVRHEAT Series 20 to other models such as TPS, CB, and CTM can provide valuable insights into optimizing efficiency and performance.
