Why a Nitrogen Generator Might Not be the Right Choice for Your Laser Cutting Operation

Onsite nitrogen generators are gaining popularity as a cost-effective means of producing nitrogen gas on demand. However, despite the apparent financial benefits, onsite nitrogen generation is far from an all-around solution. In this article, we review the reasons why purchasing a nitrogen gas generator might not be the best decision for your business.

Why nitrogen generation might not be the right choice for your laser cutting operation.

Regular maintenance means regular downtime

Regular maintenance—planned or not—can halt laser operations. A backup gas supply, like rented cylinder packs, is essential.

For quality of finish, laser grade bulk nitrogen is a cut above

Higher gas purity improves cutting but raises energy and filter costs. Traditional supply ensures consistent purity without added expense.

Capital expenditure regardless of gas use

Even with reduced gas use, companies must keep paying for their generator investment—money that might be better spent elsewhere.

The cost and effort of generator maintenance and management

Filter replacements can cost up to 50% of the initial investment. Managing generators adds complexity compared to simpler bulk or cylinder options.

Gas generators take up production space

Generators take up valuable floor space. External bulk tanks free up production areas.

The environmental impact of gas generators

Generators often run continuously, increasing power use and hindering sustainability goals.

Gas generators can impact your ability to grow

Generators produce a fixed amount of gas (with a small tolerance). Spikes in demand can put a strain on performance and reliability.

Energy prices and the impact on running costs

Compressors consume significant power, impacting profitability, which is often overlooked in purchase decisions.

Reduced noise pollution factor and improved safety

Generators can be loud, posing safety risks. External bulk systems are quieter and safer for indoor staff.

Why not consider liquid laser gas supply?

Available in our compact CryoEase® service or our bulk tank solutions for larger volume demand: a cost-effective, flexible and convenient laser gas supply.

Your high-performance laser cutting system is a significant investment requiring highly skilled operators and state-of- art technology. So it’s important to consider all the options available to find the best and most reliable assist gas supply system for your business.

Why tank supply is a cut above gas generation.

Eliminate downtime

Our tanks can be refilled at high pressure by our unique tankers, allowing you to keep your machines running, eliminating any loss in production downtime.

Save space

Gas tanks must be sited externally and gas is piped to the laser machine meaning no valuable production floor space being used to store laser gas.

Save money

There is minimal upfront investment with Cryoease® service tanks. Bulk tanks do require capital investment but once the tanks are installed, costs are lower and with full transparency.

Regular deliveries

Advanced telemetry mounted on the tanks constantly measure tank levels and ensures timely refills, saving you the hassle of raising orders and waiting for deliveries.

Save time and improve safety

With either system, there’s no more handling or changing over cylinders – and no risk of running out of gas.

More flexibility in tank sizes

As well as offering cylinders and packs, we have a range of tank sizes from 950 litres up to 60,000 litres that offer the purity, flow rate and high pressures required by laser gas operations.

Drive operational efficiencies

Both the CryoEase® service and bulk tanks offer you a constant on-stream supply. Our trucks deliver nitrogen at high pressure, straight into your tank, reducing the need to vent off gas and lose precious production time.

Sustainability considerations

Unlike gas generators which are ‘always on’, with the CryoEase® and bulk tanks you only use the gas you need, with no additional energy required – making it easier to meet your sustainability targets.
