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.
