NH3

Loading arms for flexible and safe LPG and NH3 transfers

Loading arms are great applications to ensure a safe transfer system of pressurised gasses like LPG and NH3 from one tank to another. The loading arms are frequently used for stationary tank loading/unloading of railway tanks and trucks.

Product description

The loading arms come in single or dual arm loading systems. Dual arm systems are designed for handling both the liquid and the vapour phase of the gasses at loading stations. The single arms serve a better purpose in closed circuit transfers.
