Viega Raxofix - Now Available!

The simple and quick assembly is a particular strength of Raxofix. Only three work steps are necessary for permanent, twist-proof connections: cut the pipe, mount the connector and check the insertion, press raxially - done. In contrast to other systems, the pipes do not have to be calibrated, chamfered or expanded. Time savings of up to 30% are possible.

In contrast to conventional systems on the market, Raxofix pipes and connectors can be effortlessly set up and adapted before they are pressed. Another advantage: accidentally forgotten crimps are reliably detected during a leak test thanks to the Viega Smart Connect Feature. This ensures the highest level of security.

As new as the axial crimping is, it does not require any new tools. The proven Viega Pressguns can continue to be used. All that is required is new press jaws. The combination of hinged adapter jaw and press ring, which Viega is now also offering for the plastics sector, is recommended for work in hard-to-reach areas. The Raxofix range includes press rings from 16 to 63 mm. Depending on the size, these are pressed with the Pressgun Picco (up to 40 mm) or with the Pressgun 5 (up to 63 mm).

All Raxofix pipes have a well thought-out pipe structure that withstands the highest demands in operation thanks to the thick-walled inliner. During processing, it reliably ensures kink resistance and dimensional stability. This means that all Raxofix pipes up to 32 mm can be easily bent by hand and installed at right angles on the wall at the same time. When using the bending tool with the dimensions 16 mm, the minimum bending radius is also reduced to 2xD.

Ensuring the required minimum flow when several fixtures are in use is the primary goal when installing a potable-water system, ideally using the smallest possible inner diameters. The press connectors in our Raxofix range are made by means of a sand casting process, and the internal barb do not feature O-rings, meaning cross-sections are only minimally restricted. This achieves the lowest loss of pressure of any press system for 100% PEX or multi-layer composite piping on the market. This will help you achieve the smallest possible inner diameter.

In practice, this provides many advantages in terms of dimensions compared to standard press systems for multi-layer composite piping. This leads to improved economy and easier installation because there is less disparity in dimensions between the floor distribution piping and the pipe work connecting to the fixtures.

There are significant advantages in operating the system as well: lower stagnant volumes mean better standards of hygiene for the drinking water. This also reduces delays, i.e. the wait for warm water to arrive at the tap.

The Raxofix system shows its advantages over standard systems: The low pressure losses of the press connectors guarantee a higher flow pressure with the same dimensions. In order to achieve the same flow rates with conventional systems, the pipes would have to be dimensioned larger - and that in turn increases the waiting time for hot water and the operating costs.

Drinking water is key to life. It is so important that we use this resource responsibly. Viega drinking-water systems have long been doing just that. They have been issued the WaterMark Certification, are food-safe, hygienic and meet all legal requirements. Raxofix is a clear continuation of this tradition – with minimal pressure loss and system volume.

The Raxofix range is extensive and ideal for flexible installations within a
bathroom and kitchen. Transition from the Propress pipe riser with copper piping with parts that insert directly into the T-joint or simply transition to each fixture. Directly connect a tap using a Raxofix connector, install a simple connection for a wash basin using a 19BP fitting. All of these items are available with a connection for individual feeder pipes or with two connections in order to hygienically connect each fixture into a loop-andseries system.

Series piping is a sensible way to protect the quality of your drinking water. The order of fixtures can make an effective contribution to technical hygiene assurance. Series piping is hygienic if the fixture in most frequent use is found at the end of the series. That way, when this fixture is used, the water content is refreshed at each upstream fixture.

Regardless of the order of fixtures, the total water content of the looped installation will be refreshed whenever a fixture is used. The volume flows are distributed, slowing flow speed and thereby significantly reducing loss of pressure. In comparison to T-joints and series installations, this hugely increases reach, allowing you to connect several bathrooms in a hotel or hospital, for example. Water is regularly refreshed, even if only one room is connected.
