Compressed air and high purity nitrogen are an important part of the laser cutting process. We have a wide range of high-quality cost-effective solutions to help your process run smoothly.
The industry has seen a shift in recent years away from CO2 laser to fibre lasers. This shift has reduced demand for CO2 but increased nitrogen demand significantly. Fibre lasers use a lot more N2 so some sites have struggled with tank storage space.
As a result, we’ve seen an increase in demand for on-site nitrogen generation systems. These systems are usually delivered pre-assembled on a skid requiring only electrical and pipework connections to be made on site. These systems have their own compressor and use Pressure Swing Absorption (PSA) technology to absorb and expel oxygen to atmosphere. The twin tower design allows a continuous flow of nitrogen as one tower is in operation while the other is regenerating before switching over.
This leaves a mixture of argon and nitrogen with a purity up to 99.999% which is the same as a liquid or bottled supply. That said, we’ve found from our tests that a purity of 99.99% is sufficient for most users without discolouration.
The customer was previously only using CO2 from cylinders for the various brewing processes. A number of these processes can be done using nitrogen which can be generated onsite, reducing the reliance on external suppliers.
The new equipment has given the brewery capacity for growth, while also making the processes a lot faster. They have saved money in the production process, with payback on the new machinery expected in just over a year. Plus, they are now in control of a reliable supply of nitrogen.
" The engineers are competent and responsive, and the company is proactive and supportive whilst being competitive. PPS is also very transparent. If something going wrong, they will come and tell us, there’s no battle on our hands to find out where issues lie. They take the time to look at the configurations, see whether our machines are working efficiently and check for leaks, rather than trying to upsell to us. If any staff leave, there’s very good handover ethics, which makes for a smooth and easy transition and reduces the impact on the customer. "
John Dempsey, Manufacturing Systems/Facility Maintenance Team Leader, Airedale
" We’re extremely happy with the new compressor and the service we received from PPS. The installation was a painless transition, the engineers were very professional and worked around our working hours and the fact that the company is over the road means that we get a very speedy, reactive service. The overall experience was extremely good and has caused me no headaches, which is all you can ask for. "
Andrew Walton, Operations Manager, Alco Valves
" If I need something, I pick up the phone and they jump through hoops to get it to me quickly. Glenn even found an electrician for us when ours was away and we needed urgent help.” “The customer service at PPS is excellent and we’ve got a very good relationship with the company. Glenn is a breath of fresh air, I couldn’t speak more highly of him, but everyone I’ve dealt with at PPS has been really helpful. I would definitely recommend PPS to anyone. "
David Ireland, Engineering Manager, Bond It
" I’m very happy with the service provided by PPS. They are all really professional, from the sales people to the installation engineers. I love their work ethic, they always arrived on time and got on with the job. “I was pleased and impressed with the whole job from start to finish and I’d be happy to recommend their services. "
Richard Coates, Process Engineering Manager at Habasit
" PPS provided extremely good service, the installation went very smoothly and the team were so helpful it felt like we were dealing with one big family. In particular, our main contact at PPS, John Greenwood, is a great ambassador for the company. “As for the service, it’s like going back in time and finding people who really care about doing the job well. At Manzana we appreciate old-fashioned values and we like to think that you can still trust people in business. Good customer service is rare in this day and age, and I can’t believe how helpful the team at PPS were. "
Gill Heleine, Director, Manzana Contracts (UK) Ltd
" The process was no trouble at all and the engineers were very efficient,” says Paul Townend. “There was a five-minute change over period from taking the old compressor out and putting the new one in, so no downtime with loss of production. “We’ve always had a good relationship with the company, the spares and servicing provision is excellent, and any time we’ve had a breakdown they come out straight away for us. We’re certainly happy to keep working with PPS. "
Paul Townend, Sam Weller Ltd
" There were no ifs, no buts – your guys resolved the issue within a few hours, without having to wait five days for a part. The breakdown could have meant a loss of production and sales, but Glenn pulled out all the stops, and that has gone down in my books as one of those key moments. Thanks to Pennine for looking after me yet again – long may the relationship continue. "
Matt Carroll, Engineering Manager, SGL CoPacking
" PPS are first class: professional and reliable. Whatever they say they are going to do, they do – and they do it when they say they are going to do it. They offered a top-notch service throughout and they helped us to keep the business running. We would definitely recommend the company and use them again ourselves. "
Stuart Wood, Director at SW Interiors
" Our experience with Simm Engineering has been extremely positive. Andy and Alan are brilliant and working with them was very refreshing. They know compressed air, they understand the equipment they supply and are technically knowledgeable, which has led to them giving us great advice. We will definitely be happy to continue working with Simm. "
Simon Sheaf, Sustainability Officer, AESSEAL®
" The new machine gives us better efficiency, lower costs and long-term peace of mind.” As usual, the service from Simm was great – very professional. It does what it says on the tin: good quality, good installation and a good product. We would definitely use Simm again. "
Malcolm Hathaway, Purchaser, Elite Shopfitters
" We have a very good relationship with Simm, which is the reason we changed from our previous suppliers. Everything has been super and we haven’t encountered any problems. Without a doubt Simm has done an excellent job, professionally carried out in the time scales given. "
Andy Higgs, Managing Director, Ondrives
" I was very impressed with the whole package; everything ran smoothly from first conversations to the quotation and installation. The people I dealt with were friendly and experienced, and everything brought up in discussions gave me confidence in the process. I’d certainly be happy to recommend the company to others and we’re now buying spares from your pneumatics department as well. "
Mick Beckitt, Production Manager, Paragon
" From the first phone call to Simm regarding our requirements, to the commissioning of the machine, the service offered by Simm was first class. "
