Low Noise Psa Nitrogen Generation Equipment

LDH's PSA generators can produce nitrogen with purity ranging from 95% up to 99.9995% (5 ppm oxygen) depending on the model and configuration. For applications requiring ultra-high purity (e.g. electronics manufacturing), optional purifiers can further polish the nitrogen to 99.9999% or higher. LDH also offers liquid nitrogen generators that produce liquid nitrogen typically above 99% purity.

Yes. The nitrogen produced by LDH generators meets food-grade specifications when equipped with appropriate filters. Food-grade nitrogen must be clean, dry, and free of contaminants. LDH systems ensure oil-free air input and can include particulate and hydrocarbon filters, resulting in nitrogen that meets standards like E941 (food-grade nitrogen). Many food companies use LDH generators for MAP (modified atmosphere packaging) to safely preserve foods.

The main operating cost is electricity for running the air compressor and refrigeration (for liquid N2 units). Otherwise, there are minor costs for filter replacements and occasional maintenance. On-site generation is far cheaper than buying nitrogen in cylinders - typically, the cost per cubic meter of generated nitrogen is a fraction of the cost of delivered nitrogen. Over time, users often see an 80% reduction in nitrogen expenses. LDH can provide a cost analysis for your specific usage to es

PSA nitrogen generators produce nitrogen almost immediately. After startup, you can expect to have usable nitrogen within 15-30 minutes as the system pressurizes and the molecular sieve beds stabilize. Liquid nitrogen generators take longer to reach operating temperature (typically a few hours for initial cool-down), but once running they continuously produce liquid nitrogen.

LDH generators are designed for minimal maintenance. Routine maintenance includes checking and replacing air and coalescing filters periodically (usually every 6-12 months depending on usage), and ensuring the air compressor (if included) is serviced per manufacturer guidelines. The carbon molecular sieve has a long life (many years) under proper operating conditions. LDH provides a maintenance schedule and can offer service contracts. Generally, daily checks are limited to monitoring gauges and
