Isolcell Unveils NIMOS PSA New Edition 2026 for More Efficient Nitrogen Generation in CA Storage
Isolcell's NIMOS PSA New Edition 2026 is a pressure-swing-adsorption nitrogen generator for controlled atmosphere storage that, according to company tests, can reduce the compressed-air-to-nitrogen ratio by up to 66% versus the previous generation. The system features a redesigned pneumatic circuit and optimized adsorption-cycle management for more stable flow and purity.
Isolcell has introduced NIMOS PSA New Edition 2026, a pressure-swing-adsorption (PSA) nitrogen generator aimed at cutting the compressed-air demand of controlled atmosphere (CA) storage installations. The unit produces high-purity nitrogen at 10 ppm and is designed to lower the energy footprint of the air-separation step that underpins CA fruit storage.
What changes in the new generation
The core efficiency metric in a PSA installation is the ratio between the average volume of compressed air consumed and the volume of nitrogen delivered at a target purity. A lower ratio means the compressor runs fewer hours for each cubic metre of nitrogen produced, directly reducing electricity use.
The 2026 edition targets that ratio through several hardware and control upgrades:
- a new pneumatic circuit,
- advanced management of adsorption cycles,
- improved control of flow and pressure transfers,
- optimized sizing of the process tanks.
Together these changes let the adsorbent material work more effectively, yielding more nitrogen per unit of compressed air. The system also delivers more stable output in both flow rate and purity and can operate across a range of supply pressures.
Performance data
Depending on generator size and residual oxygen concentration, tests carried out by Isolcell show reductions in the air-to-nitrogen ratio of up to 66% compared with the previous generation. The company notes that the gains are particularly pronounced when high purity levels are required.
Fewer equivalent operating hours and lower compressed-air demand translate into reduced operating costs and a smaller carbon footprint associated with nitrogen generation.
Broader context
Isolcell has long built its product line around the principle of achieving better results with fewer resources. The company's earlier work on dynamic CA technologies using fluorescence sensors slowed fruit metabolism and adapted storage conditions to actual needs, cutting running hours for CO₂ scrubbers, refrigeration systems and other equipment. NIMOS PSA New Edition 2026 extends that same efficiency logic to the nitrogen-generation stage of CA installations.
