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.

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.
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.
The machine is used to socket-weld PP, PVDF, PE pipes and fittings of O.D. 20 - 125 mm. Diamond-shaped clamps allow effortless positioning and securing of the fittings and pipes of all sizes. A specially designed fastening system is at the heart of the easy changing of the clamps depending on the job at hand.
The HWT 125 SW 2.0 features a unique reference setpoint pushbutton that enables convenient and professional adjustment of the component butt position. It goes without saying that fusion depth selectors and the corresponding spigots and sockets are available for common component types (DVS type A, DVS type B, ASTM in inches)
The system ships in a rugged, wooden transport and set‑up box (optional).
