Combining decades of industry expertise with modern automation technology, the modular platform delivers precise odourant dosing while improving safety, operational transparency, and long-term reliability, as well as simplifying operation, maintenance, and future system expansion.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Gas odourisation is a safety-critical process that requires accurate, dependable control to ensure gas leaks can be detected quickly. The new OCM has been developed specifically for these demanding applications and forms part of LEWA&#8217;s fully integrated odourisation solution, where all critical components, from the diaphragm metering pump and low-flow measurement to the odourisation nozzle and control system, are engineered to work seamlessly together. By developing and integrating these core technologies in-house, Lewa provides customers with a single-source solution that ensures system compatibility, simplifies project execution and commissioning, and delivers a single point of responsibility for long-term performance, service, and support.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At the heart of the OCM is an open, modular automation platform based on industry-standard PLC and HMI technology. The system provides precise, gas-flow-dependent control of odourant dosing, helping operators achieve safe, reproducible odourisation while meeting today&#8217;s operational and regulatory requirements.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Designed for both new installations and retrofit projects, the OCM can control up to two independent odourisation lines from a single platform, reducing engineering effort, cost, and installation complexity. It is also backward compatible with existing Lewa 19-inch systems, simplifying modernisation projects and protecting previous investments. Its modular hardware architecture allows systems to be configured for a wide range of applications while enabling straightforward future expansion.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A key feature is the new graphical Human Machine Interface (HMI) display, which provides operators with an intuitive process flow diagram, plain-language status and alarm messages, guided parameter setup, and role-based user access. This visualisation makes even complex odourisation processes easy to understand, giving operators an immediate overview of system status, improving operational transparency, reducing training requirements, and minimising the risk of human error.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The modular design also improves serviceability. Plug-in, front-access hardware modules enable rapid replacement and maintenance, reducing downtime and allowing many service tasks to be completed without specialist PLC expertise.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Built on widely available industrial-standard components, the OCM provides long-term hardware availability and investment protection while supporting modern communication interfaces, including Profinet and Modbus RTU. The platform is designed to meet current and emerging regulatory requirements, including compliance with CE, EMC, RoHS, ATEX, relevant DVGW regulations, and the Cyber Resilience Act (CRA).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The OCM is suitable for gas distribution networks, transfer and pressure regulation stations, redundant odourisation systems, modernisation projects, and new installations with advanced automation requirements. It provides a scalable platform that supports the complete lifecycle of an odourisation system, from planning and commissioning through operation, maintenance, and future expansion.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Lewa GmbH has unveiled its new Odor Control Module (OCM), the seventh generation of its proven odourisation control technology.
