Laundry/Surge Channels

29/05/20200

AusPress continues to expand our market penetration by introducing our products into new markets nationally. We have been supplying Laundry and surge channels into South Australian projects for many years, but recently we have been requested to supply these items to other states.

Surge channels are used in laundromats, aged/residential care facilities, laundries in student accommodation and defence facilities.

A surge channel slows down the flow of hot washing water into the drainage system. They have mesh barrier screens, to remove lint, paper etc. and stop it from entering the drainage system. At the end of the unit they can have a silt trap assembly, as a last step to catch any silty soil product in the system.

They are located at the rear of the washing machines, and the discharge enters into the surge channel, behind the screen lint screens. The capacity of the washing machines, determines the size of the unit required for each project.

As with any AusPress Stainless Steel manufactured product; the channels, components and accessories are 100% Australian Made

Find more information on these channels on page 8 of our Technical Catalogue,  contact our technical design department or speak to your local representative.

Stainless Press Profiles

06/02/20200

There is always much discussion about which profile is better, “M” or “V”. At times and for general plumbing installations, the performance criteria are similar, if not the same for these profiles. However, there are differences in the higher end performance for each profile.

Let’s begin with history; The first press system was developed back in the 1950’s, was patented in 1962 and was the “M” profile. At the time, the system was granted a 50 year patent protection making it difficult for any competitors. Many years later, in 1989, the “V” profile was developed and released to market. Later again, in 1997, a slightly different profile, the “SA” profile was developed and released to market.

Why are they referred to as “M”, “V” and “SA”? Well, the first system was “M” profile and developed by Mannesman GmbH, the “V” profile was developed by Viega LLC and the “SA” profile was developed by Sanha GmbH. Clearly, the companies decided to use the first letters of their company names to label the profile they had developed.

What is the difference in the appearance of the fittings? Quite simply, the “V” profile has a “tail” leading from the fitting, whereas the “M” and “SA” profiles profiles do not.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

What is the difference in the performance of the fittings? This has been a debate for many years. However, all we can refer to is the recommendations of the manufacturers of both the fittings and the tooling. Gathering all of the available information and referring to manufacturers recommendations, we have developed the below chart for reference.

Why is there a difference in the maximum allowable working pressure? It all comes down the press profile and the way the force is applied to the fittings when being pressed. As you will see in the above images, the “M” profile fitting allows for 4 press points, while the “V” Profile fitting allows for 3 and “SA” Profile allows for only 2 press points. This has a dramatic effect upon the overall security and pressure rating of the actual joint.

All manufacturers of press fittings use the same raw materials and are certified to the same standards. The biggest difference is the profile of the fittings and the tooling used. Based on all of this information, if you are looking for the maximum safety in any installation, “M” Profile fittings pressed using the appropriately rated tool (minimum 32 kN) and the relevant HP jaws should be used.

So, the next time you have a project and decide to use Stainless Press, ensure you use the right product that is fit for purpose and offers you the greatest security for your workmanship. For expert advice on any installation, please refer to our technical department.

Hygienic Drainage Solutions

18/08/20190

What’s important to your project? High Quality Hygienic Stainless Steel drainage? Watermark approval? HACCP certification? Local design and manufacturing? Experience? Top level customer training and technical support?

All of the above should be a priority. When channels are installed into your project, they are embedded in concrete. This means they cannot be removed easily, without cutting concrete and shutting down your production for a period of time. All of these factors cost money. You want to ensure you are installing a purpose made, high quality product that will last as long as the building with minimal maintenance. That’s why AusPress has been manufacturing custom made channels in Australia for nearly 20 years and is regarded as the market leader.

So, the next time you need a high quality drainage channel in your food and beverage facility, the next time you are looking to invest in your facilities future and save money on maintenance, we can assist you.
