Ritmo electrofusion welding machines for pressure pipe and drainage

What decides is the welding voltage of the fitting, not the pipe diameter. Electrofusion fittings for pressure pipelines work at 8 – 48 V and carry an ISO 13950 barcode. That is what the Elektra line is for.

HDPE building drainage – soil and waste – is welded with machines that work directly off the 230 V mains; the parameters come from the brand-specific welding cable. That is what the Mustang 160 V2 and Universal 315 V1 are for. The two worlds cannot be served by the same machine.

Yes. What matters is not the make but the fitting itself: if it works at 8 – 48 V welding voltage and carries an ISO 13950 barcode, the machine reads the parameters and welds. That applies to the common electrofusion fittings for pressure pipelines.

The supplied universal adapter 90° Ø 4.0 / 4.7 mm fits the usual terminal pins. Brand-specific adapter sets are not needed with the Elektra line.

Elektra Light and Elektra S: 3.5 – 4 kVA.
Elektra M and Elektra 315: 5.5 – 6 kVA, frequency-stable – large fittings draw considerably more at start-up.
Elektra XL: 6.5 – 7 kVA.
Mustang 160 V2 and Universal 315 V1: Ritmo states no generator recommendation for the drainage line; both run off a normal 230 V socket.

As a rule: better one size up than tightly sized. A generator that dips will break off the welding cycle with it.

Elektra Light: 325 cycles · Elektra 315: 500 · Elektra S, M and XL: 8,000 each. In the drainage line the Universal 315 V1 stores 350 reports; the Mustang 160 V2 does not produce any as standard.

Export is as PDF or BIN. On the Elektra Light the optional DB9M-USB cable is required for this.

With the Universal 315 V1, five cables are supplied: A00 (yellow, Ø 32–160 mm), A00+ (black, Ø 200–315 mm), A01 (blue), A02 (red) and A04 (white), each for Ø 200–315 mm. Cable A05 (brown, Ø 20–63 mm, PP-R) is available on request.

With the Mustang 160 V2, Ritmo states that one welding cable with 90° pins is supplied. Which make your cable needs to cover is something we clarify before ordering — give us a call.

With GPS, every weld gets its coordinate in the report. On network sites with hundreds of joints this makes it possible to prove later which connection lies where – without a separate survey.

Surcharge: Elektra M + GPS 1,889.00 € instead of 1,729.00 €, Elektra XL + GPS 2,449.00 € instead of 2,299.00 € (net).

Electrofusion welding is covered by DVS 2207-1 (PE) and DVS 2207-11 (PP). Automatic parameter transfer follows ISO 13950, traceability of the components ISO 12176-4 and that of the fusion operator ISO 12176-3.

These standards do not replace the processing instructions of the fitting manufacturer. For gas and drinking water mains a valid qualification of the operator is additionally required; the DVGW code of practice GW 330 serves as proof of this.

Yes. Cooling time is part of electrofusion welding just as it is part of butt fusion – it is simply less obvious. In butt fusion the pipe stays under joining pressure in the machine; here the joint cools without pressure, and nothing holds up the sequence.

The fitting manufacturer specifies two times. The first is given as CT on the barcode label and states when the joint may be moved – until then it is neither pulled nor backfilled. The second is considerably longer and states when the line may be put under test or operating pressure.

Both values depend on the diameter and design of the fitting and are given in the processing instructions of the respective make. The Elektra machines display the cooling time and count it down. Before commissioning there is the pressure test anyway, to EN 805, EN 12007 or DVGW G 469 and W 400.

Yes, for part of the range: we rent out Elektra Light, Elektra M, Elektra XL and Universal 315 V1. Elektra M and XL each in the basic version – the versions with GPS/Glonass are not available for rent.
