If you looked at the cost of on-site nitrogen generation years ago and found that your ROI was not there, it may be time to look again. Large nitrogen suppliers have had price increases every year just to satisfy shareholders. Has your nitrogen supplier lowered their delivery cost to you this year? Gasoline costs were given as the reason for the high delivery charges. Gasoline is at the lowest price it has been in years, yet there has been no reduction in delivery charges. During this same time, nitrogen generator pricing has remained stable. Nitrogen generators have also become more efficient (air/ nitrogen ratio) due to recent technological advancements.
Feel free to contact a CGT nitrogen generator specialist to discuss if a nitrogen generator is right for you.
