``Shelf``-CNG Dispensers
CNG dispensers of the “Shelf”-CNG series are designed for dispensing compressed natural gas at gas stations for vehicles. “Shelf”-CNG can be one-sided or two-sided with one or two hoses and are equipped with mass meters of our own production. “Shelf”-CNG gas dispensers work both in manual mode (i.e. offline mode) and in automatic mode, where the device is cis linked with the kiosk control system and the data concerning volume, sum and price are transmitted to POS. It is possible to increase the standard productivity of each sleeve (30 kg/min) to 80 kg/min. The high security of the speaker’s electronics against unauthorized interference allows the operation of the equipment, excluding the illegal actions of the station staff and service services, and the well-thought-out design of the speakers allows for maintenance with minimal time costs, while having an excellent appearance.

Assignment of the priority panel
To fill the battery Gas Accumulator Block section by section between the compressor and the GAB, it is necessary to use the priority panel (hereinafter PP). The use of PP ensures the optimization of refueling of motor vehicles under the conditions of a large flow at the CNG gas station. PPs are produced in two- or three-line versions.
Below is a diagram of a three-line PP. Gas flows from the compressor through the check valve(CV) to the high-pressure section 1. When a pressure value of 210-220 bar is reached in section 1, the priority valve PV1 opens and the gas enters the medium-pressure section 2. Then, when the pressure in section 2 reaches a value of 210-220 bar , PV2 opens and the gas flows into the low-pressure section 3. After the pressure in section 3 reaches 210-220 bar, the pressure rises in all three sections simultaneously and, upon reaching 250 bar, in the absence of gas distribution to customers, the compressor stops. PPs with a smaller or larger number of lines work similarly.
