The WhiteLine welders cover all areas of application in electrofustion welding of PE, PP, and PVDF pipes with heater coil fittings. There is no challenge for which you will not find a welder of the series able to take it on successfully.
Wherever applicable, HÜRNER’s all-purpose electrofusion welders have been developed in line with the requirements of the most recent version of the ISO standard 12176-2:2000, the DVS standard 2201-1, and the WEEE directive, with Reg. No. DE 74849106.
Whether it is jointing in the safety-sensitive area of gas networks, including accurate recording of geographic data, jointing components with very small diameters (e. g., geothermal or sanitary fitting applications) or very large diameters (e. g., wastewater applications)—the welders will always make a statement by their unyielding reliability that builds on more than 40 years of developing and manufacturing experience

This monitoring unit provides easy airflow monitoring of chemical storage cabinets. A sensor monitors the extraction airflow and triggers a visual and audible alarm when no airflow above the defined minimum is detected. The air monitoring unit without fan ships preassembled to be installed immediately on top of the storage cabinet. The alarm threshold for the airflow velocity is factory-set, but can be customized at the differential pressure meter/switch. The enclosure is made of silver pearl glimmer, powder-coated sheet steel. The airflow sensor monitors the actual extraction velocity and the entire extraction system of the storage cabinet.
Both the volumetric flow and the power supply are sensed by a microcontroller unit. When airflow velocity drops below the set threshold, visual and audible alarms are set off. The system ships with two potential-free (“dry”) contacts (24 V, 2 A) that can be used to send an alarm signal to the control center. An integrated battery cuts in in case of power supply failure, and the monitoring system and the display, including simple error messaging, can run on it for 4 hours. The product ships ready for plug-in.
HÜRNER’s welding data logger SPG 2.0 is made for easy and safe welding process control and report logging pursuant to the ISO 12176 standard.
The report generation system is specifically matched to HÜRNER butt-welding machines of the Manual Hydraulic series, but can of course be used with other systems effortlessly. The SPG 2.0 control software ships ex works with configurations for many third-party systems already installed. Therefore, the logger constitutes an upgrade for manually operated welding machines to achieve ISO-compliant recording, error handling, and welding process control. At every step in the welding process, the SPG 2.0 indicates the nominal and the actual values of the welding pressures and times, to walk the welder operating the hydraulic unit easily and correctly through the process. The unit thereby achieves the optimum welding process, in line with nationally applicable standards, as affecting both heating element temperatures and welding pressures and times.
With the HÜRNER quick mounting system, the clamps can be replaced easy as ABC. The chassis/carriage, without the RH and LH pipe‑aligning clamps, can be removed from its steel frame by simply loosening 4 mounting screws and can then be used in areas that are hard to reach or overhead.
Both the operation of the clamps for the straight pipe and the saddle fitting and the movement of the carriage for the latter are implemented as using ergonomically designed handwheels. Additionally, the motion handwheel can be removed easily, to move the clamping chassis/carriage with a common power tool (cordless drill/screwdriver) as its drive.
A special mention deserve the heating element seat next to the chassis for clamping the saddle fitting, on which to place the heating element, and the two freely adjustable depth setpoints. The easy insertion and safe and swift removal of the heating element, including centering and an auto‑detaching step in the change‑over stage, bring a use as convenient as to be considered unique.
The insertion depth setpoints provide, on the one hand, consistent fusion depth and welding position and, on the other, shorter length of movements, thus faster change-over.
Special octagonal clamps for branch‑off fittings, of various wrench sizes, are also available.
