Russia’s HVAC (Heating, Ventilation, and Air Conditioning) market is undergoing a fundamental transformation. Driven by massive infrastructure modernization, a harsh climate that demands reliable heating and cooling, and a strategic pivot toward import substitution, the industry is booming. For manufacturers, engineers, and distributors, the most efficient route into this multi-billion dollar market is Russia’s dynamic circuit of HVAC trade shows.
From colossal winter exhibitions featuring hundreds of Chinese manufacturers to landmark mergers that are reshaping the industry calendar, here is the definitive guide to the most important HVAC trade shows in Russia for 2026 and beyond.
Aquaflame: The Undisputed Industry Giant
When discussing HVAC in Russia, the conversation starts with Aquaflame. Formerly known as Aquatherm Moscow, this exhibition successfully completed its rebranding in 2024 and has emerged as the largest and most influential engineering solutions trade show in Russia and the CIS region.
The 30th edition of Aquaflame took place from February 3–6, 2026, at the Crocus Expo International Exhibition Center in Moscow, and the scale was breathtaking. The event covered 32,500 square meters and brought together 587 exhibitors from 12 countries, attracting over 23,000 unique professional visitors.
A Hub for International Collaboration
Aquaflame 2026 demonstrated the truly global nature of Russia’s HVAC market. The event was notable for the massive participation of Chinese manufacturers—250 companies from 16 Chinese provinces exhibited, with nearly 50 of them presenting in high-profile custom-built stands. This strong presence underscores China’s strategic role in supplying critical components, from valves and fittings to advanced pumping solutions, filling gaps in the Russian supply chain.
Beyond China, the exhibition hosted official delegations from Turkey, Armenia, and the Embassy of China, signaling the event’s importance as a platform for international trade. The exhibition floor featured nine distinct product groups, covering everything from heating equipment and water supply systems to pipes, fittings, instrumentation, and a specialized Pool & Spa sector.
Innovation and High-Impact Networking
Aquaflame is more than a static display of products; it is a launchpad for innovation. The 2026 edition saw the premieres of several groundbreaking engineering solutions:
- DKM launched its Baikal series of steam boilers.
- TAIFU introduced a new 3GRS variable frequency circulation pump.
- BWT demonstrated a record-setting filter with a 4-second backwash cycle.
The event also featured 22 high-profile concurrent events, including the “BIM & BEM Technology Conference,” the “Water Treatment & Pool Market Forum,” and the energetic “Aquaflame PRO Installer Championship”. The prestigious AQUAFLAME AWARDS recognized industry leaders, with Rusklimat winning “Product of the Year” for its innovative bimetallic radiator.
The 365-Day Digital Ecosystem
What truly sets Aquaflame apart is its commitment to year-round engagement. The Aquaflame Connect digital business community extends the life of the exhibition far beyond its four-day run. In 2026, the platform facilitated over 43,900 digital lead scans, with 496 companies using the smart matchmaking service. With nearly 60,000 active users, Aquaflame Connect has become a vital market intelligence hub and networking tool for the Russian HVAC industry.
The next edition, Aquaflame 2027, is scheduled for February 1–4, 2027, once again at Crocus Expo.
AIRVent: The Specialist’s Choice for Ventilation & Cooling
While Aquaflame covers the broader engineering spectrum, AIRVent focuses specifically on ventilation, air conditioning, and refrigeration (AC&R). Held concurrently with Aquaflame in February 2026 at Crocus Expo, AIRVent is the dedicated platform for climate control specialists.
The 2026 edition saw impressive growth across all metrics:
- Exhibition area: 16,400 square meters, a 21% increase from 2025.
- Exhibitors: 213 companies from 7 countries, a 33% year-on-year increase, with 104 companies making their debut.
Major global brands like Daichi, Dalgakiran Pumps, and TION chose AIRVent for their Russian market premieres. The event attracted 9,666 specialized visitors from 20 countries and 81 Russian regions, with additional cross-traffic from the Aquaflame show.
A Forum for Technical Excellence
AIRVent is renowned for its high-level technical content. The 2026 event featured 10 major conferences with 70 speakers and 816 attendees. Highlights included the 9th International Ventilation Congress and a plenary session on “Merging Ideas and Technologies for a Safe Indoor Climate”.
The inaugural AIRVent Awards recognized excellence in innovation, energy efficiency, and import substitution. VRK Factory won “Innovative Product of the Year” for its concealed slot ventilation diffuser, while THERMEX ENERGY was honored for its free-cooling chiller for data centers.
Looking ahead, AIRVent 2027 will return to Crocus Expo, running concurrently with Aquaflame from February 1–4, 2027.
Climate World: The New Calendar Challenger
For decades, Climate World (Climate World Moscow Exhibition) was the primary winter alternative to the Aquaflame/AIRVent duo, typically held in February at the Timiryazev Center in Moscow. However, 2026 marks a strategic shift for this long-standing event.
Moving to November: A Strategic Reschedule
Starting in 2026, Climate World is moving from its traditional winter slot to November 10–13, 2026, at the Crocus Expo IEC. This strategic move is designed to align with the purchasing cycles of corporate and government clients, allowing suppliers to present their products at the time when annual budgets for the following year are being finalized.
The MEGAPOLIS EXPO Super-Platform
More significantly, Climate World is merging with two other major industry events—MITEX (International Exhibition of Tools) and UtiliCon (Exhibition for Utilities and Urban Complexes)—to form a unified mega-event called MEGAPOLIS EXPO.
This integration creates a powerful synergy, bringing together climate control professionals with developers, facility management companies, government clients, and construction firms. The 2025 precursor to this format (covering separate but co-located events) occupied 60,000 square meters, featured 993 exhibitors from 8 countries, and attracted 38,600 visitors from 85 Russian regions.
Olga Moiseeva, CEO of the EUROEXPO Group, explained the vision: “Holding MITEX, UtiliCon, and Climate World simultaneously on the same platform provides an opportunity for a comprehensive demonstration of solutions for construction, operation, engineering infrastructure, and the urban environment. This format allows participants to interact with several professional audiences at once and build new business contacts in related industries more quickly”.
The 2026 Climate World will showcase the full spectrum of HVAC/R technology, including air conditioning, ventilation, heating, refrigeration, automation, fire safety solutions, and data center cooling systems. A key focus will be on import substitution, production localization, and energy efficiency.
The Verdict: A Maturing Market with Two Powerhouses
Russia’s HVAC industry now offers two distinct, high-value exhibition experiences for industry professionals:
| Event | Dates for 2027 | Venue | Best For |
|---|---|---|---|
| Aquaflame & AIRVent | Feb 1–4, 2027 | Crocus Expo, Moscow | Broad engineering solutions, international networking, plumbing, heating, pools, ventilation, and cooling. |
| Climate World (part of MEGAPOLIS EXPO) | Nov 10–13, 2026 | Crocus Expo, Moscow | Climate control specialists, aligning with corporate/government procurement cycles, integration with construction and utilities sectors. |
For exhibitors, these events offer an unprecedented opportunity to connect with serious buyers. At Aquaflame 2026, 93% of visitors had key decision-making authority in their companies, and 46% attended no other similar exhibitions. Similarly, exhibitors at AIRVent reported high satisfaction, with 83% satisfied with their participation and 74% finding new customers on-site.
Whether you are a manufacturer of industrial boilers, a supplier of smart ventilation controls, or a distributor of refrigeration components, Russia’s HVAC trade shows offer the most direct route to one of the world’s most demanding and opportunity-rich markets. The industry is consolidating, innovating, and building for the future—and these exhibitions are where the blueprints are unveiled.
