STOREX VSA N2 GENERATORS

Nitrogen is used for an accelerated pull down of the oxygen content at the start of CA storage. Breathing is slowed down faster and that is good for preserving the hardness of apples. It is also useful to lower the oxygen content with nitrogen after the cells have been opened in the meantime.

If the oxygen content rises during storage due to (unwanted) leakage, a small amount of high-purity nitrogen is injected into the cell to prevent leakage.

Nitrogen is therefore important to keep the oxygen content low.

Energy efficient - reliable operation - lowest maintenance costs

Energy efficient - reliable operation - lowest maintenance costs

Storex VSA N2 generators produce nitrogen at a low pressure of approx. 1 bar. using an oil-free low-pressure blower and regeneration using vacuum. This technique, originally developed by Storex, has important advantages:

  • Lowest energy consumption for N2 production; Savings up to 30%
  • Lowest maintenance costs
  • VSA is the proven most reliable N2 production system
  • LOWEST TOTAL COST OF OWNERSHIP FOR N2 PRODUCTION

EASY OPERATION:

  • Easy to operate
  • Nitrogen is produced with a low pressure air stream of approx. 1 bar. guaranteed without oil residue
  • Compare this with PSA systems with compressed air at 8 bar with possible oil residues
  • Various models ranging from 10m³ N2 to 100m³ N2/hour (97%N2/ 3% O2)
  • Automatic production of high flow nitrogen with a purity of 97%N2 / 3% oxygen for a fast pull down and nitrogen with a high purity N2 99% / 1% O2 for control of low oxygen targets in the cold store
  • Many models use a maintenance-free blower and a maintenance-free Mink claw compression type vacuum pump (virtually no maintenance)
  • Smart options available for remote control
  • Can operate stand-alone and is controlled by an external operating system

OPERATING PRINCIPLE OF VSA N2 GENERATORS

Storex VSA N2 generators have 2 barrels filled with CMS activated carbon suitable for the production of nitrogen. Outside air is blown through one vessel using an oil-free low-pressure fan at a pressure of approximately 1 bar, where the oxygen is adsorbed and the concentrated nitrogen (99%-97%N2) leaves the generator. On the other vessel, the adsorbed oxygen is removed with a vacuum pump. The process time is approx. 1 minute, after which the processes on the vessels alternate. Thus, nitrogen is continuously produced. Storex developed this VSA technique for fruit cultivation in 1993 and this concept has since become very successful and the standard due to its reliable operation and low costs for the production of nitrogen!!

Options:

  • Supply system via pipe or PVC HP pipes + valves to CA rooms
  • Dual flow for production of 2 purity grades. Arranged automatically     
  • Measurement of purity of nitrogen produced
  • Pressure measurements of both vessels
  • Automatic control of O2 in connected CA rooms
  • Automatic O2/CO2 control for 1 or 2 CA cells
  • Recirculation system for extra energy efficiency
  • Mobile units
