Spantech engineers revamps psa nitrogen generators and air dryers of any make or type which are not being used due to variety of reasons. A nitrogen generator is generally taken out of service due to mechanical malfunctioning [eg, valves not operating, control system not working] or for not delivering nitrogen at the rated capacity and/or purity. Revamping of a nitrogen generator involves operations such as cleaning and testing of adsorption towers, filters, receivers, piping etc; cleaning/repairing/replacing including pressure and operational testing of each valve separately; repairing/replacing and testing of timer and other control elements such as pressure and temperature switches/indicators, pressure gauges, reassembly and pressure testing of the generator as well as operational testing of the valves and control system; and replacement of cms, filter elements, catalyst, as required and final testing and purging with nitrogen prior to dispatch.
