The Airgas539 Series IntelliSwitchFullyAutomatic Switchover System provides a continuoussupply of high purity, non-corrosive gas, non-flammable gas from either cryogenic liquid or high pres-sure cylinder sources. Microprocessor control lowers the yearly gas cost by eliminating liquid cylindervent loss and excess residual return when using cryo-genic liquid cylinders as a gas source. Electronic source controls allow change from high pressure to anypressure liquid cylinders at the push of a button. Lowloss and electronic economizer functions ensure troublefree use and real gas consumption savings with fully automatic switchover controls. NEMA 12 enclosure standard, NEMA 4 optional enclosures provide LED displays of inlet and outlet pressures as well as complete system functions. Field adjustable switchover pressure and keypad lockout are some of the manyunique functions standard with this system. The pigtailsare flexible stainless steel for easy cylinder connection
