How to combine liquid and on-site gas supply

As production costs rise, many businesses are looking for smarter industrial gas solutions.

 

Combining liquid and on-site gas supply is a strategic solution for industries that rely on a steady supply of industrial gases like nitrogen and oxygen. By integrating these two supply methods, businesses can achieve a flexible, cost-effective, and reliable gas supply that maximizes efficiency and reduces operational costs.

Why is integrated liquid and on-site gas supply a strategic choice?

Liquid and on-site gas generation

Traditionally, businesses either depend on bulk liquid gas deliveries or invest in on-site gas generators. Each method has its advantages, but combining the two unlocks an even greater level of efficiency. By integrating liquid nitrogen and liquid oxygen supplies with an on-site PSA generator, you can maximize resource utilization, enhance cost-effectiveness, and ensure uninterrupted gas supply at all times.

Key benefits of integrating liquid and on-site generation

Cost-Effective

On-site generation covers daily needs, while liquid supply acts as a backup for peak demands. Reduces reliance on bulk liquid deliveries and lowers transportation costs.

Reliable

Ensures a continuous gas supply, preventing downtime. Provides fail-safe redundancy so you never run out of gas.

Flexible

Adapts to changing production demands. Ensures optimal gas usage without excess supply or shortage.

Scalable

Easily adjusts gas supply as your business grows. Avoids costly infrastructure overhauls. Making it ideal for industries with variable production demands.

How does the integration work?

  • The on-site generator is configured with a supply pressure slightly higher than that of the evaporated liquid gas.
  • The generator acts as the primary base supply, covering all standard production needs.
  • Whenever demand exceeds the generator’s capacity, the liquid supply automatically steps in, ensuring an uninterrupted flow of gas.
  • If there’s ever an issue with the liquid supply, the on-site generator provides a backup, maintaining production stability. 

This hybrid approach reduces waste, optimizes gas usage, and provides a fail-safe mechanism for industries that cannot afford downtime.

How do I get started?

1. Assess your gas supply needs

To effectively combine liquid and on-site gas supply, it's essential to evaluate your current gas usage and infrastructure.

2. Choose the right on-site generator

When comparing generators, consider the following:

  • Flow rate capacity: Can it meet your production demands?

  • Pressure output: Must be slightly higher than your liquid supply pressure.

For nitrogen supply, determine whether you need a standalone generator or a full nitrogen skid package.
