Collection: CTM Engine Heaters
Despite its small footprint, efficient forced circulation allows the HOTflow® CTM system to heat engines up to 20 liters in displacement, allowing for a wide variety of weather-protected small engine applications. Multiple options are available, including UL/C-US listed and CE-compliant models.
The CTM’s inlet and outlet may be reoriented at 90° increments to accommodate heater plumbing. The included mounting kit is ideal for most installations; an optional vibration isolation kit is also available. Forced circulation provides uniform heat throughout the engine, reducing component maintenance and offering significant energy savings - resulting in end-user utility cost reductions up to 35% (savings are dependent on local utility rates and installation variables).
