Themen
We deliver condition monitoring for reactors, pumps, and compressors, real-time monitoring of temperature, pressure, and vibration in process plants, as well as predictive maintenance solutions. The platform processes sensor data from across the entire chemical park and presents it in customized dashboards.
Yes. Via Modbus, OPC-UA, and MQTT, we seamlessly connect existing control systems to the IoT platform. Sensor data from LoRaWAN networks and traditional fieldbus systems are consolidated in a unified interface – without interfering with running processes.
Vibration and temperature sensors continuously capture the condition of critical equipment. Using ThingsBoard rule engines and machine learning models, we detect anomalies early – before unplanned downtime occurs. This significantly reduces outage time and maintenance costs.
We work with ATEX-certified sensors and gateways for Zone 1 and Zone 2 areas. The hardware meets the requirements of the ATEX Directive 2014/34/EU and is approved for use in explosive atmospheres with flammable gases and vapors.
ATEX-certified gas sensors continuously monitor the concentration of critical substances in the ambient air. When defined thresholds are exceeded, immediate alerts are triggered via the IoT platform – via push notification, SMS, and integration with existing safety control centers.
Yes. We coordinate sensor selection and placement with your explosion protection officer and document the integration into the existing zone classification. All installations are performed and documented in compliance with IECEx and ATEX standards.
Yes. Beyond standard dashboards in Grafana and ThingsBoard, we build custom web apps and mobile apps – for example, mobile condition monitoring cockpits, inspection round apps for plant operators, or compliance reporting tools for environmental officers.
Our stack: ChirpStack as the LoRaWAN network server, ThingsBoard for device management and rule engine, Grafana for real-time dashboards, and Node-RED for data flow automation. SCADA integration via Modbus and OPC-UA. Custom apps are built with React, Next.js, and React Native.
Yes. Via ThingsBoard and Node-RED, we integrate LoRaWAN, MQTT, Modbus, and OPC-UA sources into a unified platform. This allows condition monitoring data, gas detection, and environmental values to be analyzed across locations and forwarded to existing control systems.
On GDPR-compliant infrastructure in German data centers. For chemical companies with special security requirements, we also install the platform on-premise at the chemical park – including VPN connectivity for our remote maintenance.
SLA tiers with availability guarantees up to 99.9%. Redundant infrastructure, automatic failover, and 24/7 monitoring ensure uninterrupted operations – essential for safety sensors and process monitoring in the chemical industry.
Yes. We install and harden the entire IoT stack directly in your data center at Chemiepark Marl. Via a VPN-secured connection, we handle proactive monitoring and remote maintenance without process data leaving your network.
Simple monitoring setups can be operational within a few days. More complex projects involving ATEX certification, control system integration, and custom development are planned in phases with clearly defined milestones – typically 4 to 12 weeks to production.
No. Our managed services are cancellable monthly. We rely on strong collaboration and demonstrable results rather than contract lock-in.
Yes. We design multi-tenant platforms for companies with multiple plant areas at the chemical park – whether Evonik, Vestolit, or Ineos. Each area gets its own dashboards, access controls, and alerting profiles. Cross-location analytics are also supported.
