Regulator for sequential injection systems with integrated filter
Tomasetto LPG pressure reducer, model AT09, is an electronic single stage reducer, suitable for sequential injection systems, homologated in accordance with the ECE 67R-01 and 10R-03.
This reducer is equipped with a solenoid valve and an integrated filter unit at its inlet, in order to reduce the overall costs and permit an easier and faster installation.
Outlet pressure is adjustable from 0.9 to 1.8 bar (pressures calculated with the reducer disconnected from the engine).
Model AT09 is available in three different versions:
AT09 ALASKA
Model AT09 ALASKA version is the most popular version of AT09 family; it is equipped with an additional post-heating stage, suitable for medium-sized engines (up to about 90 KW).
AT09 ALASKA SUPER
Model AT09 ALASKA is also available in SUPER version, with bigger internal passages and piloted solenoid valve, that provides an higher flow and extends the power range up to about 100 kW.
AT09 ARTIC
Model AT09 ARTIC version is equipped with a pre-heating stage at the inlet and it is particularly appropriate for cold weather conditions, and suitable for medium-big-sized engines (up to about 110 KW). This reducer is out of production since July 2022, but the maintenance kit RGAT2091 stay available.
