What Citius Engineering does

Cilyx (operating as Citius Engineering) is a Belgian engineering company based in Herstal that designs and manufactures turnkey production machinery and automation systems, with a primary focus on the life sciences sector — pharmaceutical fill-finish, bioprocessing, syringes/vials/cartridges handling, implants and micro-implants manufacturing — and a secondary focus on general industrial production systems, test and measurement solutions, and mechanical engineering services. Its product portfolio is built around a set of proprietary, named platforms: the PUPSIT automated integrity testing system for sterile filtration, the CALICUT horizontal and VERTICUT vertical precision cutting systems (CALICUT co-developed with Thermo Fisher Scientific), the MICROCUT micro-cutting system, the RN600 automated renester operating at 600 cycles per minute for prefilled syringes, the ADS automated distribution system for single-use bioprocessing, ring welding equipment, and NAGINELS-based serialization solutions for glass containers, complemented by an in-house design office offering mechanical and electrical engineering, sizing and simulation, project management, and after-sales services. The business model is B2B direct sales of custom-engineered equipment to enterprise customers in pharmaceuticals, biotechnology, and aerospace; pricing is quote-based and not publicly disclosed, with each project representing a multi-stage engagement from design through installation and qualification. The company operates primarily in Belgium and Europe, distributes via its own website (cilyx.eu), LinkedIn, and YouTube channels, and has no disclosed external funding, parent company, or acquisition history, operating as an independent private business with 11-50 employees.
