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.

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.
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.
