ENGINEER & MARVEX 2026 is back with a bang, taking engineering out from behind the scenes and onto the exhibition floor to create one powerful meeting ground for the people, technologies and ideas.
From 22 to 25 September, the Kuala Lumpur Convention Centre will host ENGINEER & MARVEX 2026, bringing together more than 1,000 solutions across 9,700sqm and five exhibition halls. Be here to witness the transformation of how we build, power and operate the future, alongside 150+ industry expert speakers and over 100 hours of knowledge sessions.
Now in their fifth editions, ENGINEER, the Engineering Exhibition & Conference, and MARVEX, the Air-Conditioning, Refrigeration & Ventilation Exhibition, are jointly organised respectively by IEM and C.I.S, and MACRA and C.I.S.
See how technology works
This year, we’ve stacked up the tech to bring you three Live Showcases that pull apart the infrastructure shaping what comes next. See what it actually takes to keep the digital economy alive at the Data Centre Infrastructure Live Showcase. Follow energy from renewable generation through storage, management and distribution at the Battery Energy Storage System (BESS) Live Showcase. Then step inside the HVAC Innovation for Smart & Green Building Live Showcase, where airflow, energy efficiency and real-time building intelligence converge. See the technologies transforming HVAC&R from conventional cooling to the intelligent backbone of smarter, greener, healthier and higher-performing buildings.
The industry’s biggest questions, answered
ENGINEER & MARVEX brings the industry’s key technical and strategic conversations together through the Kuala Lumpur Engineering Forum 2026 (KLEF), Future Ready Green Data Centre Symposium, Urban Engineering Symposium 2026, ASEAN-China-Europe HVAC&R Forum and A.C.E Conference 2026. On the floor, Power Talk: Industry and Power Talk: Business get down to what matters, how new technologies work, where the industry is heading and where the opportunities are. And for engineers, there is another compelling reason to be here: up to 32 BEM CPD hours across four days.
Making its debut is the co-located Data Centre Exhibition Asia (DCX Asia), sharpening the spotlight on the mission-critical electrical, mechanical, HVAC&R and power infrastructure supporting Asia’s rapidly expanding digital economy.
Across the four days, visitors can also catch the Air-Conditioning & Refrigeration Installation, Testing & Commissioning Skills Competition, and the ENGINEER & MARVEX Excellence Awards, recognising products and solutions pushing performance, design and sustainability forward.
Come to see the technology, and stay to understand it. Meet the people behind the projects. Find your next supplier, partner, solution, client or idea. Because this is where the industry connects, knowledge moves, business gets done and hands shake. If engineering, HVAC&R, energy, data centres or the future of buildings is your business, KLCC is where you need to be.
