Self-Contained Oxygen Generator

Modular PSA oxygen generators are engineered around the concept of scalability, allowing enterprises to adjust their oxygen production capacity in line with their growth or fluctuating needs. Unlike fixed-size systems, which require full replacement to accommodate increased demand, modular units can be expanded incrementally by adding more modules. This design philosophy ensures that small enterprises are not burdened with oversized equipment, while larger facilities can scale up without disrupting existing operations.

A small-scale food processing plant may start with a single modular unit producing 5Nm³/hr of oxygen for modified atmosphere packaging. As the business expands, it can add a second module to double capacity, avoiding the cost and downtime of replacing the entire system. Conversely, a large metallurgical plant with variable production schedules can temporarily deactivate modules during low-demand periods, reducing energy consumption. This adaptability makes modular PSA generators a cost-effective choice for enterprises of all sizes, balancing immediate needs with long-term growth potential.

A regional hospital can use a NEWTEK modular system to supply oxygen to its wards and operating theaters. During peak periods, it can activate additional modules to meet increased demand, ensuring uninterrupted supply for critical care units. During quieter periods, it can scale back, reducing energy waste.

Large enterprises require high-volume oxygen production with the flexibility to adapt to complex, variable demands. NEWTEK's modular PSA generators meet these needs through robust, customizable systems that deliver consistent performance even at scale.

High-Flow Modules: NEWTEK's industrial-grade modular units can produce up to 300Nm³/hr of oxygen, with the ability to combine multiple modules to reach even higher capacities. This makes them suitable for applications, where oxygen is used in large quantities for combustion enhancement.

Customized Configurations: Large enterprises often have unique requirements. NEWTEK's 3D design services and turnkey solutions allow for customization, ensuring modules fit seamlessly into existing workflows. A gold mining operation can request modules with enhanced corrosion resistance to withstand harsh mining environments.

Redundancy and Reliability: To prevent downtime in critical operations, large-scale modular systems have redundant components and backup modules. If one unit requires maintenance, others can continue operating, ensuring uninterrupted oxygen supply.

A large metallurgical plant can deploy a NEWTEK modular system with multiple interconnected units, producing 300Nm³/hr of oxygen for steel processing. During scheduled maintenance, it can isolate one module without halting production, maintaining efficiency. As the plant expands its production lines, it can add more modules to match increased oxygen demand, avoiding the need for a complete system overhaul.

Modular systems eliminate the need for over-investment in fixed-capacity equipment. Small enterprises pay only for the capacity they need, while larger ones avoid the expense of replacing entire systems when scaling up. This incremental approach to investment aligns with cash flow realities, making oxygen generation accessible to businesses at every stage of growth.

Whether adjusting to seasonal demand, expanding production, or downsizing during slow periods, modular generators allow enterprises to adapt quickly. This flexibility is particularly valuable in industries with variable workflows.

Modular systems operate most efficiently when matched to current demand. By activating only the necessary number of modules, enterprises reduce energy waste-a benefit for sustainability goals and cost management. NEWTEK's variable-speed compressors and smart monitoring further enhance efficiency, ensuring that energy usage scales with production.

As enterprises grow or pivot their operations, modular generators can evolve alongside them. A brewery expanding into canning can add modules to support increased oxygen demand for packaging, while a hospital adding a new wing can scale up its oxygen supply without disrupting existing services. This adaptability ensures that the initial investment in a modular system continues to deliver value over time.

A small aquaculture farm in Southeast Asia uses a NEWTEK modular generator producing 5Nm³/hr of oxygen to aerate fish tanks.
