262-367-4299

Mounted to reservoir designed for bi-directional air flow during fill cycle (filtered inlet air).

Unique interface mounts only with Hartmann DEF Receiver preventing introduction of the Ammonia based DEF into other fast fill systems.

The Hartmann Receiver is uniquely designed to compensate for expansion due to fluid freezing and is the fill point for ground level fill.  It is compatible only with the Hartmann DEF Nozzle.  The non-standard interface prevents cross contamination with fuel, coolant, etc.  

 

Optional Heated Receiver

Prevents overfilling of DEF tank and also communicates with the filling nozzle, allowing disconnection under pressure.

DEF compatible heaters for in-tank and component applications.

Mounted to reservoir designed to exhaust air during fill cycle.
