Modular Protection System

Request a Brochure

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.

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.

The design of the machine is such that pipes, segments O.D. 50 – 250 mm / 1½"– 8" with any SDR ratio up to SDR 11 can be processed. The system was developed under the machinery directive 2006/42/EC as amended, as far as applicable, and is set on a welded and bolted, totally heavy-duty support frame resistant to warping by design. Both the movable carriage of the system and the console carrying the heating element and the facing tool travel on precision-engineered, heavy load-bearing shafts and trapeze-shaped guides constructed with smoothly travelling runner blocks. Inserting the PTFE-coated heating element and the facing tool manually is as convenient as it is effortless. The swiveling master clamps on both sides can be rotated by up to 2 x 15 deg. (∢30 deg.) and also feature horizontal adjustability, to allow for compensating any misalignments. Heating element temperature control and facing tool operation are managed on the front panel. The practical wooden transport case serves both as a operating platform and as secure storage for the machine, the reducers, and the accessories.

Fluid Media Management System

This fluid media management system with a programmable control terminal and numerous functional modules ensures highest levels of occupational safety. One control terminal can be used to control several chemical storage cabinets and can be set up with various modules. In its standard model version, the system allows selecting the components needed for a planned system from the following modules: Identification module which makes sure that only authorized persons are given access to the hazardous substances in question. In active storage mode, the media are released only subsequent to proper identification. This is implemented in the form of the input of a programmable PIN. The identification can also be implemented, upon request, with transponder keys or biometrical readers. Air extraction monitoring module which monitors the air extractions and triggers alarms as appropriate. The air extraction has to be always operating on cabinets that can go into active storage mode. When it is, it must constantly verify that there is a flow of extracted air and must alert to the problem whenever the airflow should fail. The air extraction monitoring module is a way to comply with this requirement, i.e. when extraction airflow fails, an alarm is triggered and a signal is sent, e.g., to the control center. Dosing module which enables exact filling. The dosing module turns the release of very small quantities of fluid media from large storage units into a process that it just as easy as it is safe. The ideal add-on to a COMPLEX Line drum station, there is the possibility, besides dosing, to ensure continuous analyses of consumed and remaining quantities. Level sensing module which alerts to the risk of overflowing storage units. The level sensor drastically reduces any risk of bringing too much media into a storage unit, and the safety of both the user and the environment increases accordingly. The level sensing module is the part that completes the perfect solution, DISPOSAL Line. Combining the DISPOSAL Line and the COMPLEX Line brings you the ideal preconditions to ensure easy and safe media management. Door opening module which opens the door when switched on at the keypad. When the command was entered and confirmed, an audible signal alerts the user to the door being opened. The control by compressed air does not have any electrical or electronic component, which makes it perfectly suited for explosive atmospheres. Door locking module which enables pairing door locking and door unlocking to user identification, thereby restricting access to the fluid media to those persons authorized to use them. In other words, access control for personnel can extend to the access to the chemical storage cabinets.

Extraction Monitor without Fan

Request a Brochure

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.
