High pressure cylinder filling ramp or filling manifold is used for filling cylinders with gases at pressures up to 450 bar.
This ramp is an example of custom made filling ramp, which includes control system, two pressure gauges, two temperature gauges and two safety valves. Filling manifold has 20 flexible hoses for filling oxygen cylinders of various connections. In this case 10 connections CGA540 and 10 connections CGA870. The filling pump is controlled by the control panel, which is equipped by oxygen safety valve, thermometer, pressure gauge and pressure switch. Alarms on pressure and temperature switches block the operation of the liquid oxygen pump, while it can be started again after all conditions are in safe zone.
