In July, we enhanced our operations by installing a second “Nitrocube” system, boosting our on-site Nitrogen gas production. For those unfamiliar with the industry, here’s why this matters.
Why Nitrogen Gas is Essential Nitrogen gas is a significant expense in laser cutting due to its multiple crucial roles:
- Assist Gas: It blows away molten material, ensuring clean cuts.
- Shielding Gas: Prevents oxidation in stainless steel, avoiding rough, discoloured edges.
- Safety: Unlike Oxygen and compressed air, Nitrogen is inert and does not support combustion.
- Abundance: Comprising 78% of Earth’s atmosphere, Nitrogen is readily available.
Environmental Impact of Liquid Nitrogen Traditionally, Nitrogen is stored as a high-pressure gas or liquid. Using liquid nitrogen involves several environmental downsides:
- Transport Emissions: From production to storage facilities, often internationally.
- Road Damage: Caused by heavy tankers.
- Gas Waste: During transfer and low usage periods.
Our Sustainable Solution Years ago, we stopped using liquid nitrogen. However, due to our growth, we had to reintroduce it as our production couldn’t keep up. With our new energy-efficient equipment, we now have the electrical capacity to further increase on-site nitrogen production and once again eliminate the use of liquid deliveries.
Reliability and Cost Benefits This year, delayed liquid nitrogen deliveries disrupted our production. Our increased on-site generation will enhance reliability. Additionally, rising costs due to energy and transport surcharges have made liquid nitrogen more expensive. By generating more nitrogen on-site, we can avoid these extra costs, allowing us to offer more competitive pricing.
