OMISA WhiteLine - HST 300 Print+ 2.0

The 300 line of welding units represents a product platform of more than 40,000 units sold around the world, which combine compact dimensions with the highest performance. Even electrofusion fittings with a diameter of over 2000 mm don’t meant any issues for this product line.
The OMISA HST 300 Print+ 2.0 is the most recent member of the 300 line. The new model version,
too, makes a difference by its professional welding control characteristics and data traceability management, incl. PDF data transfer via Bluetooth, for an operating range inclusive of fittings of up to 1200mm of diameter.

OMISA Electrofusion Welder - HST–S–315 2.0

OMISA’s all-purpose electrofusion welder HST–S–315 2.0 offers easy, expertly and convenient jointing with PE fittings sized 16 – 315 mm in wastewater and roof draining applications. Controlled by a microcontroller, this next-generation welder is equipped, of course, with a feature compensating temperature by welding duration and with an input voltage and an output voltage monitors. The welder, thereby, is your convenient choice for power supply from a generator on a worksite, too. The welding process is monitored for its full duration, and all relevant information is displayed on the seven-segment screen. Needless to say, the welder ships with all connection adapters, A00, A01, A02, A04, and A0P (for Waviduo 200 – 315 mm).
Furthermore, the standard delivery includes a handheld scraper meant for professional preparation of the pipe for the welding. With its very compact dimensions and its long power supply and welding cables, the welder offers an enormous working radius, turning it into a helper that allows working at even those lines that are awfully hard to reach.

Water Supply Fittings for the Building Technology Sector
Our pressure reducing valves with potable water approvals, both with threaded or flange connections do not only cover all classic areas of the water supply sector: They are often used for applications in sprinkler systems, in water-treatment or desalination plants. The materials of all wetted parts do not only fulfill the stringent national DVGW regulations but also those in France (ACS), the UK (WRAS) and Norway (SINTEF).
Addition Construction Steps
We will work with all project team members to define the logistical requirements for the construction process, such as areas for deliveries, placement of barricades (if required) and hours of operation.
