Hydronic Heater Autoterm Flow 14D-12 (-24)


Hydronic Heater Autoterm Flow 14D can be installed in commercial trucks, boats up to 50′, heavy equipment and school buses.

Pre-start engine coolant heaters work independently from the engine. They heat up the engine coolant to provide an easy start at low temperatures. At the same time, they can supply hot air to the passenger cabin/compartment keeping it warm and dry.

Hydronic Heater Autoterm Flow 14D comes with a programmable controller PU-27 or PU-28 with timers and automatic temperature control.

There are two modifications available: 12 V and 24 V
