LPG Reducer Model AT09 NORDIC

Reducer for sequential injection systems with integrated filter

The AT09 Nordic reducers, the latest evolution of the AT09 sequential reducers family, has been designed with the aim of further improving the performance compared to the other reducers of the AT09 family, Alaska and Artic, thanks to the improved heating circuit and the higher support engines power, up to 125kW.
This reducer differs on the integral body, the complete separation of the water and gas circuits, the improved gas circuit and the deeper water circuit, which allows a better heat exchange.

LPG Reducer Model AT09 NORDIC XP

Reducer for sequential injection systems with integrated filter

The AT09 Nordic XP reducers, the latest evolution of the AT09 sequential reducers family, has been designed with the aim of further improving the performance compared to the other reducers of the AT09 family, Alaska and Artic, thanks to the improved heating circuit and the higher support engines power, up to 180kW.
This reducer differs on the integral body, the complete separation of the water and gas circuits, the improved gas circuit and the deeper water circuit, which allows a better heat exchange. The model NORDIC XP is equipped with a double membrane system, that allows to get an increase of the LPG outlet pressure when increasing the engine load (Dynamic Pressure Compensation). This system allows to support engines with higher power, giving an higher outlet pressure able to support the good working of the injectors, with an optimal carburation control and the improvement of the calibration process.

LPG Reducer Model AT13 XP

Reducer for sequential injection systems with high performances

EXTRA POWER – EXTRA PRESSURE – EXTRA 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. The 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.

LPG Reducer Model AT09 ALASKA and ARTIC

Reducer 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 verion 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).

LPG Reducer Model AT07

Two stage electronic reducer for traditional systems with integrated inlet filter

Tomasetto LPG pressure reducer, model AT07, is a two stages electronic reducer, suitable for traditional carburated systems. It is homologated in accordance with the European Regulation ECE 67R-01. Model AT07 is equipped with an inlet solenoid valve and an integrated filter unit, to reduce the overall costs and permit an easier and faster installation.
This reducer is equipped with a double regulation system to obtain always the best performances.
Three different versions, suitable for different engines, are available in our range.

LPG Reducer Model AT10

Electronic reducer for 2-wheelers and little vehicles (traditional applications)

LPG reducer model AT10 is a 2 stages electronic reducer, suitably developed for applications on motorbikes and small vehicles, with LPG withdrawal in vapour phase (this reducer is not provided with heating circuit).
The reducer is homologated as per the ECE 67R-01, is really compact and equipped with an integrated solenoid valve, that reduces hindrance, permitting an easier and faster installation.
This reducer is designed exclusively for two-wheeler and small three-wheelers applications. Upon request, it is also available the version with pressure switch (no solenoid).
