CNG Reducers Model AT12


Tomasetto CNG AT12 pressure reducers is avaiable in two versions: STANDARD and SUPER. In this range it is also included an LNG version for special applications on liquid natural gas systems.

AT12 STANDARD
Model AT12 Standard version is a 2 stages reducer, equipped with a low pressure solenoid valve (to be used with in-line cng cut-off valve).


AT12 SUPER
Model AT12 super version is a 2 stages reducer, equipped with an integrated high pressure solenoid valve at the inlet. This version allow not to use a line solenoid valve in the system, and it also gives higher performances.


AT12 LNG
Model AT12 LNG version, is a single stage reducer for special applications on liquid natural gas systems, equipped with a low pressure solenoid valve. Also avaiable without solenoid valve.
