The Malaysian Engineering Exhibition and Conference (Engineer) and Air-Conditioning, Refrigeration and Ventilation Expo (Marvex) 2026 took place from Sept 22 to 25, 2026, at the Kuala Lumpur Convention Centre (KLCC), showcasing cutting-edge digital, HVAC&R (heating, ventilating, air-conditioning and refrigeration) and clean energy technologies.
The engineering showcase put the latest tech behind AI-ready cooling systems, smart building automation and advanced energy management infrastructure on display to tackle rising ambient server heat.
Jointly organised by the Institution of Engineers Malaysia (IEM), the Malaysian Air-Conditioning & Refrigeration Association (MACRA), and C.I.S Network Sdn Bhd, the four-day confex platform brought together industry professionals, technology providers and decision-makers across the engineering and HVAC&R value chain.
The exhibition featured more than 260 local and international brands, showcasing over 1,000 M&E (mechanical/electrical) and HVAC&R solutions, alongside the co-located DCX Asia (Data Centre Exhibition Asia) under the theme Powering Asia’s Digital Backbone, across five exhibition halls spanning 9,700 sq metres.
Speaking at the opening ceremony of the Engineer & Marvex 2026 on Sept 22, the Deputy Minister of Energy Transition and Water Transformation Dato’ Sri Abdul Rahman Mohamad said Malaysia aims to lead the regional energy transition by growing its renewable energy capacity and developing the ASEAN Power Grid.
“As the ASEAN Power Grid takes shape and our renewable energy capacity grows, we have an opportunity to develop and supply clean energy solutions across the region.
“Over the coming decade, Malaysia has an opportunity to lead the energy transition. Its success will depend on the engineers and industry partners who turn policy into working projects,” he said.
Three live showcases covering Data Centre Infrastructure, Battery Energy Storage Systems (BESS), and HVAC Innovation for Smart & Green Building brought engineering applications into a live environment.
Led by chief curators Ir Lee Cheng Pay, Ir Alex Looi Tink Huey and Ir Au Chong Hun, the live exhibit demonstrated how technologies are being applied to address real-world infrastructure and building challenges.
The breadth of solutions on display reflected the rapid evolution of the M&E, HVAC&R and data centre sectors, driven largely by rising digital demand, sustainable building practices and the energy transition.
From critical power and cooling systems to automation, energy management, battery storage, building controls and data centre infrastructure, the exhibition provided a cross-section of technologies supporting the performance and resilience of modern buildings and digital infrastructure.
Engineer & Marvex serves as a working trade environment designed to bridge the gap between technology providers and the professionals who handle engineering and M&E systems.
By bringing together the people who design systems with the people who manufacture and buy them, it streamlines every stage of the project lifecycle from product discovery and technical evaluation to specification, sourcing, business matching and project development.
This commercial focus also provides businesses with insight into emerging demand and new applications across Malaysia and the wider regional market.
CIS Network president Dato’ Vincent Lim said the ASEAN region is currently experiencing a massive wave of significant investment in energy, infrastructure, data centres, manufacturing and the built environment.
“The opportunity is there to connect the people building what ASEAN will need next. That is why we are putting the spotlight on where the future is taking shape.
“Engineer & Marvex brings the exhibition and conference together as a confex platform, connecting the industry through technology, knowledge and expertise – and creating the space for those connections to turn into business opportunities.”
IEM president Ir Yau Chau Fong said that Engineer & Marvex and the concurrent IEM Convention successfully merge two critical sides of the industry ecosystem into a single unified platform.
“The exhibition brings the technology, products and solutions, while the convention brings the knowledge, expertise and professional exchange.
“Put them together, and we have a platform where the profession and industry can come together, exchange knowledge, explore opportunities and turn conversations into action,” he said.
MACRA president Gan Chok Ser said the industry-led platform is intentionally designed to move beyond traditional product showcases by bringing professionals together to drive the industry forward.
“When we bring all these elements together, we create a stronger environment for the HVAC&R industry to connect, learn and grow,” he said.
Beyond the exhibition floor, the conference programmes featured over 100 hours of sessions and more than 150 local and international speakers, across the Kuala Lumpur Engineering Forum, Marvex Forum, A.C.E Conference, Future Ready Green Data Centre Symposium, Urban Engineering Symposium and Engineer & Marvex Power Talks.
Professionals who attended across all four days of the Engineer & Marvex 2026 event can earn up to 32 Board of Engineers Malaysia (BEM) Continuing Professional Development (CPD) hours.
The event also provided exhibitors an additional platform to showcase their latest engineering and HVAC&R innovations.
The Marvex Air-Conditioning & Refrigeration Skills Competition showcased the technical capabilities of HVAC&R professionals, while the IEM Ideas Competition and Career Matching Day, organised by the IEM Young Engineers Section, offered huge benefits for both emerging engineers and the wider industry.
