HÜRNER WhiteLine WeldControl 2.0

Request a Brochure

The handling of a WeldControl machine is simply unique and it enables an approach to welding no other system is able to offer. Either the operator makes use of the assistance of the interactively responding hydraulic and control unit. Or the manual mode is selected to make the joint “by hand”. In the WeldControl mode the system walks the operator through the process after the pipe parameters were entered or confirmed. This includes monitoring the operator’s inputs and recording the entire process. WeldControl machines do not only provide presets, though; they facilitate the work, e. g., by reducing the pressure automatically when the automode was enabled. Welding reports have all data required by ISO traceability. In the Manual mode the display screen works as a digital gauge. It displays the welding pressures and heating element temperatures and is a one-stop provider of all data. Industry version: Optionally, the machine chassis (250, 315, 355, 500, 630) are also available in an industry set-up with a modified 3^rd clamp for clamping fittings with a short connecting stub.*⁾ *⁾Retrofit kit for converting existing systems to industry version available upon request!

Modular Protection System

Protect your chemical storage cabinet against unauthorized access, using the Modular Protection System (MPS). This system enables you to physically control the access to resources or hazardous substances in a state-of-the-art approach.

The identification ensures that only authorized persons are given access to the hazardous substances in question. This is implemented in the form of programmable PINs read from a transponder card by RFID technology. The identification can then be paired to the locking or the unlocking of the door of the cabinet. This means that the authorizations of personnel can extend to the storage cabinets as well.

The MPS is an important module to comply with increasingly tight requirements in terms of risk assessment as related to access control. In practical implementation, this may mean for you that work instructions providing for the safe and controlled use of hazardous substances can allow less complex routines, as, e.g., TRGS 526.

A functionality the MPS provides is the possibility to automatically close the door. This means that the cabinet takes care of door closing after the door was manually opened.

Electrofusion Without Report Logging

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.

HWT 125 SW light

All-purpose socket welder for PP, PP-R, PVDF, PB, and PEHD fittings and pipelines in the range of dimensions from O.D. 20 - 125 mm, for professional overhead welding and operations in a confined space, yet also for standard workshop applications.

In its standard delivery, sockets and spigots size O.D. 63 - 125 mm are included, with O.D. 20 - 50 mm as an optional extra. With the HÜRNER quick mounting system, the clamps can be replaced easy as ABC. The clamping chassis can be removed from its steel frame by simply loosening 4 mounting screws and can, therefore, be used in areas that are hard to reach or overhead.

Both clamping the pipe and the fitting and moving the machine carriages are implemented as using ergonomically designed handwheels. Additionally, the motion handwheel can be removed easily, to move the carriages with a common power tool (drill / cordless screwdriver) as its drive. A special mention deserves the heating element seat of the clamping chassis, on which to place the heating element. The feature ensures easy insertion and safe removal of the heater, thereby providing reliable change-over management and convenient use that are unique in this category of welding systems.

Electrofusion With Report Logging

The lighthouse products, HST 300 Pricon 2.0 and HST 300 Print+ 2.0, have an extremely intuitive data download menu enabling also transfer via Bluetooth, which allows downloading all welding and traceability data or a finely tuned selection of them, as an abstract or extended report in the PDF format, as a label tag printed with the optional printer, or as well in the DataWork format for processing on a PC.

HWT 630 CS

HÜRNER's HWT 630 CS servo-operated workshop system is the end-to-end transformation of worksite technology into workshop systems. The system has been developed in compliance with the so-called machinery directive 2006/42/EC as amended and allows making segments, tees, Y pieces and crosspieces in workable dimensions from O.D. 160 through 630 (500) mm | 6" - 24 (20)". The welding system is set on a welded or a screwed-fast, heavy-duty, no-warp support frame and the bearings on which move both the horizontally traveling carriage and the heating element and facing tool assembly, are designed as precision-engineered and heavy load-bearing trapeze-shaped guides with precision-matched runner blocks. It goes without saying that all parameters that are critical for a high-quality and reproducible welded joint are monitored throughout the process and saved to the memory of the system, which can hold up to 10,000 reports. Furthermore, all CNC systems are equipped with a USB interface to enable downloading the welding reports in the PDF format to a USB stick or sending them to the management database in the HÜRNER DataWork Professional format. It is also possible to label a joint immediately for its quality by printing on plastic foil an indelible label tag with the available tag printer that will identify the fitting.

HWT 400 Line

HÜRNER's HWT 400 Line is the end-to-end transformation of worksite technology into workshop systems. As a consequence, the HÜRNER HWT 400 mm workshop line, too, has systems of the versions CNC (HWT 400 CS and HWT 400 CS-S), WeldControl (HWT 400 WeldControl), and Manual Hydraulic (HWT 400 M). All systems have been developed in compliance with the so-called machinery directive 2006/42/EC as amended and allow making segments, tees, Y pieces and crosspieces in workable dimensions from O.D. 90 through 400 mm (3 - 16" IPS). The HWT 400 CS-S is equipped with additional master clamping assemblies designed for sidewall fusion onto the pipe saddle. The control software has been specifically adapted to allow one-sided preheating of the straight pipeline. The welding systems are set on a welded or a screwed-fast, heavy-duty, no-warp support frame and the bearings on which move both the horizontally traveling carriages and the heating element and facing tool assembly, are designed as precision-engineered and heavy load-bearing trapeze-shaped guides with precision-matched runner blocks. For the product versions CNC and WeldControl, it goes without saying that all parameters that are critical for a high-quality and reproducible welded joint are monitored throughout the process and saved to the memory of the system, which can hold up to 10,000 reports. Furthermore, all CNC and WeldControl systems are equipped with a USB interface to enable downloading the welding reports in the PDF format to a USB stick or sending them to the management database in the HÜRNER DataWork Professional format. It is also possible to label a joint immediately for its quality by printing on plastic foil an indelible label tag with the available tag printer that will identify the fitting.

Filter Units with Fan

This filter with fan provides positive extraction and monitoring of chemical storage cabinets, in the form of almost 100% decontamination of the extracted air by molecular adsorption filtering of harmful solvent vapors (hydrocarbons). The filter operation means optimum protection for the user. As a consequence, no additional air extraction outlet is needed, which, in turn, allows the filter unit to be operated immediately next to, or on top of, the storage cabinet. The decontaminated air is released into the ambient air, thereby not consuming any heated or air-conditioned air from the room. A sensor monitors the extraction airflow and triggers a visual and audible alarm when no airflow above the set threshold is detected. The enclosure is made of silver pearl glimmer, powder-coated sheet steel. As an air extraction system, it as of today complies with “green lab” requirements, while offering you full flexibility of position. The multi-stage, grounded filtering system offers dual safety, being composed of: Activated carbon filter with twice as much activated carbon — for up to 100% decontamination Additionally a DIN EN 779-compliant particulate filter The filter alert appliance can be set at the differential pressure meter/switch. The filter elements themselves and the filter enclosure lid are monitored by ATEX-compliant micro-switches. The three-month check and replace interval of the activated carbon filter is verified by a check report the user has to confirm which is paired to a scheduler. The product ships ready for plug-in.
