Selected projects — cleanroom installations, HVAC systems and laser cleaning applications.
Expert consultancy for regulated environments. GMP/cGMP compliant cleanroom solutions and industrial laser cleaning trusted by global pharmaceutical leaders since 2010.
Founded in 2010, EKO HVOK d.o.o. began delivering HVAC design and installation for commercial buildings. Over time, we evolved into a specialist Life Science consultancy — and a pioneer in industrial laser cleaning technology across Europe.
Today we provide ISO 14644-compliant HVAC systems, air filtration consultancy, cleanroom design and build support, facility classification, validation guidance, and pulsed fiber laser cleaning services — all within GMP/cGMP quality frameworks.
We operate across Ireland, Switzerland, Italy and Croatia, working within the quality systems of the world's leading pharmaceutical and biotech companies.
Full compliance with current Good Manufacturing Practices and EU/FDA pharmaceutical regulatory standards. Documentation aligned with 21 CFR Part 11, Annex 1 and EU GMP guidelines across all projects.
Design and advisory for HVAC systems meeting ISO 14644-1/2 cleanroom classification. HEPA/ULPA filtration, unidirectional and turbulent airflow design, differential pressure cascade management.
20+ years applying Last Planner System and lean construction methodology for on-time, on-scope delivery of complex pharmaceutical projects — from Design Qualification through OQ/PQ validation.
Pulsed fiber laser technology for non-contact surface decontamination. Rust, oxide, coating and residue removal without abrasives or solvents. Repeatable, measurable, ISO-traceable results.
Non-contact, non-abrasive pulsed fiber laser cleaning for industrial and pharmaceutical surfaces. Removes rust, oxides, paint, oil, grease and particulate contamination without chemicals, abrasives or secondary waste streams. ISO-compliant, CE-certified, with repeatable and fully auditable results.
End-to-end consultancy for GMP-compliant cleanroom facilities in Life Science and pharma. From URS and concept design through IQ/OQ/PQ validation. ISO 14644 classification, Annex 1 compliance, particle count certification and environmental monitoring strategy.
Comprehensive HVAC system design and air filtration solutions for commercial, industrial and pharmaceutical environments. HEPA/ULPA filter selection, air change rate calculations, differential pressure monitoring, and regulatory compliance documentation.
Our portfolio includes world-leading pharmaceutical, biotechnology and life science organisations across Ireland, Switzerland, Italy and Croatia.
Expert articles on cleanroom technology, industrial laser cleaning, and GMP compliance for Life Science and pharmaceutical facilities.
ISO 14644-1 defines airborne particulate cleanliness classes for cleanrooms and controlled environments. Understanding classification — from ISO Class 1 (ultra-clean semiconductor fabs) to ISO Class 9 — is essential for GMP facility design, regulatory submission and operational qualification. Key parameters: maximum permitted particle concentrations at 0.1 µm, 0.2 µm, 0.3 µm and 5 µm thresholds, measured by laser particle counters under ISO 14644-2 monitoring protocols.
Pulsed fiber laser cleaning delivers a precision alternative to abrasive blasting — no blast media, no chemical residue, no substrate micro-damage. For regulated environments such as pharmaceutical manufacturing or aerospace MRO, non-contact laser ablation eliminates cross-contamination risk and secondary waste streams entirely, while delivering measurable, repeatable surface cleanliness verified by optical profilometry and XRF analysis.
Designing a GMP-compliant cleanroom requires alignment with EU GMP Annex 1 (2022 revision) for sterile manufacturing, ISO 14644 classification, and facility-specific URS documentation. Critical design decisions: airflow regime (unidirectional vs. turbulent), HVAC zoning, differential pressure cascade (+15 Pa minimum between grades), HEPA terminal filter placement, and a comprehensive validation protocol strategy spanning DQ, IQ, OQ and PQ phases.
Industrial laser rust removal uses focused photon energy — typically 1064 nm Nd:YAG or fiber laser wavelength — to ablate iron oxide (Fe₂O₃/Fe₃O₄) layers from steel, cast iron and aluminium alloy substrates without mechanical contact, chemical agents or thermal distortion of the base material. The result: a metallically bright surface (Sa 2.5 equivalent) ready for coating, welding or precision measurement, with cycle times 40% faster than traditional abrasive methods and no hazardous waste disposal.
