It is fast, effective and exceptionally low risk, using significantly less water than many other techniques.
Our Ice Pigging™ equipment enables a customer to clean their pipework at a touch of a button, always ready within their facility, be that in a factory, at the dockside or within their production plant.
Our dedicated team of Ice Pigging™ specialists, engineers and the operations teams are based in Bristol. This facility houses our testing lab and the manufacturing centre for our Ice Pigging™ machines that are distributed worldwide.
Each installation of Ice Pigging™ equipment is unique. The Ice Pigging™ engineers start with a feasibility assessment and site survey to understand the pipeline processes. Often the team will conduct product trials in our Bristol testing facility using the clients products and simulated pipe properties.
The Ice Pigging™ system will be specified. A suitable Ice Pig™ additive will be selected to act as a freezing point depressant that suits the situation. This may be salt, sugars, alcohol or acids. In addition the ice quality will be customized to suit the product, process and hygiene requirements.
A plant integration plan will be developed that identifies the Ice Pig™ injection locations, the process line modifications, component specifications and the factory machine communication.
As the Ice Pigging™ machine is commissioned, the Ice Pigging™ engineers will provide installation support and training. The team can also provide further support to expand the Ice Pigging™ application and to optimise Ice Pigging™ performance following factory changes.
The AQL500 is our most commonly installed Ice Pigging™ machine. The AQL500 is a patented, factory ready and fully automated machine that operates on a continuous basis, capable of delivering ‘always-ready’ ice for the purpose of Ice Pigging™ enclosed pipes.
The machine manufactures a two-phase ice slurry using potable water and a selected additive as a freezing point depressant. The purpose of the freezing point depressant is to control the structure of the ice slurry and to prevent the ice from forming large crystal sizes. Salt is often used, but sugars, alcohols, acids and many other commonly found base ingredients can be used to suit the product or materials being cleaned out and operating requirements.
A complete Ice Pigging™ system enclosed within steel panels, the machine combines ice production, ice storage, maintenance and Ice Pig™delivery all in one unit.
The AQL200 works in conjunction with the AQL500 as a portable Ice Pig™ carrier and delivery unit. It takes the ice made in the AQL500 to other parts of the production facility or plant that isn’t directly attached to the AQL500. It is most suitable for those facilities where a line needs less frequent cleans.
On some occasions an alternative Ice Pigging™ solution has been required to suit location situations and so Ice Pigging™ machines have been customised for those particular client circumstances.
With two patents for the technology, Ice Pigging™ requires a level of expertise and skill that cannot be found outside of SUEZ. Involved with Ice Pigging™ from its commercial beginnings and with over 90 years of Ice Pigging™ experience between them, our team of Ice Pigging™ operating specialists and engineers have unparalleled expertise in cleaning pipes with ice.
We thought this pipe was uncleanable, in part because it was so inaccessible, but Ice Pigging™ worked. We are really impressed with the standard of work, level of professionalism and all round well done for the job
The Ice Pigging™ approach has significantly improved the speed and standard of clean. The customer has now adopted this for their hardware cleaning programme and purchasing two customised machines to be installed at their facility.
As an engineer myself I was very interested and involved in the project and could see the benefits of Ice Pigging™ straight away compared to traditional pigging systems. Ice Pigging™ technology has great potential.
SUEZ did a great job in allowing us to deliver our project on time. The Ice Pigging™ equipment was new to us, SUEZ recognised this and made our project run smoothly by explaining at the right level of detail at each stage, from equipment specification right the way through to shipping and delivery. Communications with the SUEZ team were always open and easy, they listened to our requirements, enabling them to understand the detailed specifications and timelines that were required. I look forward to working with SUEZ and Ice Pigging™ again on the next project
The ease of the operation and the way the team went about it and how efficient you were was really impressive and it was nice to see some thought going into the whole process rather than just sending the ice down and hoping for the best.
Ice Pigging™ is a brilliant concept of special pipe cleaning problems. Not only removing sediment but also removing the bio-film! After Ice Pigging™, the PVC pipes we had pigged looked like new inside
A 100% improvement in flow rates due to a build-up of abattoir waste on the pipe wall. Ice Pigging™ saved £2000 a day in contracted waste tankers.
The pipe was cleaned over two nights with the main isolated for only 6 hours in total, resulting in no customer disruption and over 323kg of material removed from the two sections. Ice Pigging™ has allowed the company to reverse flows in a pipe which previously, would have been impossible at such short notice.
We were delighted and relieved that Ice Pigging™ very successfully removed biofilm from our ultra-pure water loops
Ice Pigging™ has proved to be a ‘game changer’ for us. Ice Pigging™ has now been adopted for other production sites
