LPG Reducers Model AT13 XP

Reducer for sequential injection systems with high performances


The LPG reducer model AT13 XP is the new version of the AT13 family, designed for highest power engines reaching 275 kW in cold weather conditions.

New AT13 XP has been designed with the Dynamic Pressure Compensation System (like Nordic XP): the special double membrane system allows an increase of the LPG outlet pressure while increasing the engine load. Thanks to a special additional plate and redesigning water and gas circuits, this model has the highest heat exchange and gas flow in our LPG reducers’ range.

The reducer has a double gas outlet, allowing the direct connections of 2 injectors. This feature allows to reduce pressure drops on the circuit, making it suitable for higher power engines.

AT13 XP is fitted with internal discharging system of safety valve overpressure through MAP connection, hence there is no need to connect an additional pipe.

New AT13 XP will take the place of previous version "Antartic Super".
