Gas BottlesAn OverviewWhy Use Gas Bottles?A standard hydro-pneumatic accumulatorcan provide approximately 25 to 30% of its fluidcapacity in usable volume (e.g., approx. 38 gallonsof capacity in a piston-type to obtain 10 gallons offluid volume; approx. 42 gallons of capacity in abladder-type to obtain 10 gallons of fluid volume).The size of the accumulator can be reduced,though, by providing additional gas volumeto the accumulator in order to expel a greaterpercentage of usable fluid volume from the unit(e.g., with Piston-type, the addition of approx. 28gallons of pressurized gas capacity will allow thereduction of the necessary accumulator volume to14 gallons and still receive 10 gallons of usable fluidvolume; with Bladder-type, the addition of approx.31 gallons of pressurized gas capacity will allowthe reduction of the necessary accumulator volumeto 11 gallons and still receive 10 gallons of usablefluid volume) Note: above approximations based on3000 PSI max pressure/2000 PSI min pressure.Since gas bottles are simply pressure vessels utilizedto store a quantity of pressurized gas (normallynitrogen) without an internal bladder or piston, theeffective cost per gallon of volume is less than theaccumulator itself, thereby making gas bottles a costeffectivemethod of supplementing fluid volumes.Example of TypicalGas Bottle/Accumulator SystemPLUGGEDPLUGGED27GASBOTTLEGASBOTTLEGASREMOTECHARGINGBLOCKFLUIDMANIFOLD FOR CONNECTIONOF MULTIPLE UNITSTO SYSTEMwww.Tobul.com
