Ground tank units for gas filling stations (GFS)

ПА units are intended to receive, store and produce liquefied petroleum gas at the automobile gas filling stations and points with operating temperatures not lower than minus 40 and not higher than 50°C and with operating pressure not higher than 1.6 MPa, the installation method is of ground type in the areas with seismicity not more than 6 M.

Possible equipment:

  • level gauge of УПП, УПП2, УПЭ1, УПЭ2, УБ-П types;
  • manometer of МТП type;
  • top-level indicator of СУС-16-ПП06-И-1 type;
  • safety valve of СПППК 4-40;
  • three-way valve of КТРП-100-25 type.
