CNG Regulators Model AT12 SUPER

Regulator for CNG sequential injection systems

Tomasetto CNG pressure reducer model AT12 is a 2 stages pressure reducer for sequential injection systems.
Compact and very reliable, it is homologated in accordance with ECE R110, approved in accordance with Enargas, Inmetro and other local regulations. The outlet pressure is adjustable from 0.12 to 0.25 MPa to always obtain the best performance.The reducer inlet is provided with an adjustable swivel fitting and the connection for the pressure manometer. In the new version 2019, the main body shape has been modified in order to improve the heating circuit and to allow the use of bigger water fittings d.16 mm (when needed); it is also possible to put water fittings in 2 different layouts (parallel or at 90° like in previous version) with the aim to ease the installation.

AT12 SUPER

Model AT12 super version is equipped with an integrated high pressure solenoid valve at the inlet. This version allows not to use an in-line solenoid valve in the system and gives higher performances, in terms of gas flow.
