 Gas cylinders and dewars are becoming relics thanks to the advent of gas-generation systems. These generators turn compressed gas into nitrogen, and deionized water into hydrogen gas. Over the last several years, advances in technology have significantly increased use of these on-site gas generators. Membranes, specialized adsorbents and catalysts, improved air compressors, and enhanced electronic controls have fueled this wave of progress.Gas generators provide consistent, Ingersoll–RandSs3L3StartUpKitModel97338099 reliable, on-site supplies of gases that are instantly ready for use. and since gas generators eliminate the need to store gases, they also do away with injuries caused by lifting and dropping heavy metal cylinders. doing away with cylinders also eliminates the costs of maintenance, shipping, returning, and storing them. there is also no need to keep hydrogen generators away from oxidizing gases or to locate generators in specially constructed ingersoll–randss3l3startupkitmodel97338099 areas. with the integration of the motor, vsd, and magnetic-bearing system, the capacitors required for the motor and drive can be used as a backup power source for the bearings in the event of a power outage or emergency shutdown.capacity and efficiencyamong the key parameters affecting performance are capacity (tons) and efficiency (kilowatts per ton). the compressor''s capacity ranges from 60 to 90 tons, depending on the operating conditions. plans call for that range to be extended to 150 tons water-cooled and 115 tons air-cooled by the end of 2004 with the use of r-134a refrigerant. an r-22 version ingersoll–randss3l3startupkitmodel97338099 is planned for retrofit applications.efficiency improvements ingersoll–randss3l3startupkitmodel97338099 stem from a combination ingersoll–randss3l3startupkitmodel97338099 of the centrifugal compressor, permanent-magnet motor, and magnetic bearings. within the compressor, efficiency is affected by the compressor isentropic efficiency (the efficiency of the wheels), ingersoll–randss3l3startupkitmodel97338099 the motor, and the bearings. traditional induction motors of this size typically are in the 92-percent efficiency range. this compressor''s permanent-magnet motor has an efficiency of 96 to 97 percent. the motormost hermetic compressors use induction motors cooled by either liquid or suction-gas refrigerant. induction motors have copper windings that, when alternating current is run through them, create the magnetic fields that cause the motor to turn. these copper windings are bulky, adding size and weight to the compressor.two-pole, 60-hz induction motors operate at approximately 3,600 rpm. a higher number of revolutions per minute can be obtained by increasing the frequency. compressors that require higher shaft speeds tend to use gears. while gears are a proven technology, they create noise and vibration, consume power, and require lubrication.the magnet-bearing compressor features a synchronous permanent-magnet brushless dc motor with a completely integrated variable-frequency drive (vfd). the stator windings found on conventional induction motors are replaced with a permanent-magnet rotor. alternating current from the inverter energizes the armature windings. the stator (excitation) and rotor (armature) change places. no commutator brushes are required. the motor and key electronic components are internally refrigerant-cooled, so no special cooling is required for the vfd or the motor.
