View service detailsVentilation design & specialist systems
Ventilation system design support—from site investigation and airflow requirements through concepts, retrofit planning and coordination. Professional engineering is provided through qualified engineering partners where required, including for complex nuclear and high-risk ventilation systems.
HEPA filtration & clean environments
HEPA filter installation and replacement, integrity testing, and particle-count checks for cleanrooms, laboratories, healthcare and other sensitive spaces.
Fume hood testing & IAQ
Fume hood airflow and performance testing, plus indoor air quality assessments and particle monitoring with clear field reporting.
Facility performance
HVAC equipment inspection and practical maintenance recommendations that support reliable operation and long-term asset care.
A practical approach
Good engineering starts with seeing what the system is actually doing.
We bring hands-on measurement and specialist ventilation experience to each project. The aim is simple: understand current performance, explain what the readings mean, and give your team useful next steps.
“Clear measurements. Useful answers. Better-informed decisions.”
