Nitrogen generation is more reliable then bottled gas as purity levels tend to vary in bottled gas. Also when returning gas bottles to the supplier, remaining small quantities in the bottles are wasted. And bottled gas is reliant upon operators ordering it regularly, causing downtime if an order is missed or if the supplier is slow to deliver.
SMP supplied a complete nitrogen generation system that was able to meet their nitrogen gas usage requirement. The system consisted of an Avelair EVO compressor, oil/water separator, air receiver, desiccant dryer, Nano Gen2 nitrogen generator, Coltri 36 high pressure nitrogen booster, and high-pressure air storage banks.
The system is on a 5-year lease and the client has a maintenance contract with SMP. The nitrogen generator is expected to save the client around £1,000 a week on nitrogen gas. Once the 5 year lease is over, that saving increases.
