FCH - Piston Accumulator Piston Accumulators Advantages of Using a Piston Accumulator Large pressure differentials are acceptable between maximum and minimum pressures Vessels can be sized to exact volume requirements.
Horizontal orientation is acceptable Aggressive fluids can be considered.
Non catastrophic failure if all the gas is lost. Piston position indicators can be provided if exact location of piston is required. Large volumes of gas back up bottles can be fitted. Capacity is only limited by pressure and available material. FCH Standard range is 1 litre up-to and including 150 litre.
