Concern:


Eleven years ago, Edwards Engineering Services responded to the growing demand for profile cutting services, leading to the creation of Cut Fold NZ to cater to this specific aspect of the business. Brian Edwards, Director, needed to ensure that a consistent and reliable Nitrogen supply was available onsite for Cut Fold NZ's high-powered laser cutting machine - one of the largest in New Zealand. The concern stemmed from the fact that running out of nitrogen would halt the cutting process and affect operations significantly.


The solution:

To address the need for consistent and reliable Nitrogen supply, Brian opted for a comprehensive solution - a high pressure Pneumatech Nitrogen PPNG Skid 12 HE package for their laser cutting application. This included: The compact and sturdy base frame contains a complete high-pressure nitrogen generation system: a VSD compressor, a high-pressure booster, a premium PSA nitrogen generator, and all necessary air and nitrogen storage and treatment. This turnkey set-up not only ensured a continuous nitrogen supply but also allowed our customer's business to operate 27/5 without worry about interruptions due to oxygen shortages.

The Results:


Installation and commissioning of the containerized solution was achieved and the Pneumatech Nitrogen Skid has been currently operating "flawlessly", currently production between 99.995% and 99.999% purity. 

As a result of this strategic investment Cut Fold NZ has seen a significant saving on costs and energy reduction, and are accompanied by newfound independence from third-party suppliers, providing the customer with full control over their production capacity. Additionally, the switch to an in-house nitrogen supply system led to a reduction in the environmental impact of truck deliveries of liquid nitrogen (LIN). Furthermore, the energy-efficient solution implemented not only contributed to sustainability goals but also resulted in significant savings in production costs overall. This holistic approach not only optimised operational efficiency but also underscored the company's commitment to environmental stewardship and cost-effectiveness.

Pneumatech Nitrogen Generators PPNG: Onsite gas generation tailored to your needs

 Empower your operations with the intelligent choice of producing nitrogen on-site. Opting for an on-site nitrogen generator in New Zealand is a superior, cost-efficient, and sustainable alternative to traditional gas deliveries. Switch from Liquid Nitrogen to On-Site Generation and Cut Your Operating Cost Down.

PSA technology

Utilizing PSA technology, Pressure Swing Adsorption (PSA) effectively isolates nitrogen from compressed air by utilizing adsorbent materials. By passing the air through a vessel containing Carbon Molecular Sieves (CMS), the oxygen is captured, allowing only nitrogen of up to 99.999% purity to exit. PSA generators are well-suited for applications requiring high-flow and high-purity nitrogen.
