CNG Dispensing Systems

IMW CNG dispensing systems – commonly referred to as dispensers and fill posts – use only high quality materials, fittings, and electronic components to ensure fast and accurate filling of all types of natural gas vehicles (NGVs). These products are proven durable and reliable at some of the world’s largest CNG taxi and bus fleets as well as numerous public fuelling stations. All our dispensing systems are tested and calibrated to meet applicable standards for fuelling accuracy.

Fill Posts

IMW manufactures a variety of fill posts for high-volume trailer filling as well as low volume time-fill systems. These systems come with many of the same features as the IMW 3000 series dispensers but are configured for economy and efficiency in situations where public fuelling is not required, such as bulk transportation systems and centralized fleets. IMW fill posts can be configured with 1, 2 or 4 fill hoses to fit any type of vehicle parking arrangement
