Moscow‘s HVAC (Heating, Ventilation, and Air Conditioning) market is currently experiencing a rapid transformation. Driven by stringent import substitution policies, a massive housing stock modernization program, and extreme continental weather, the demand for reliable climate control technology has never been higher.
In 2026, the industry calendar is defined by two distinct “seasons”: the massive winter blockbuster February Expo Week (featuring AIRVent and Aquaflame) and the specialized autumn summit Climate World in November.
Here is your essential guide to the most critical HVAC events in Moscow.
The Winter Blockbuster: AIRVent 2027 (February)
Date: February 1–4, 2027
Location: Crocus Expo, Pavilion 3
AIRVent has rapidly established itself as the specialized heavyweight for ventilation, air conditioning, and refrigeration in Russia. Celebrating its fourth edition in 2026, this event is solely dedicated to “climate equipment,” making it the sharpest tool for professionals focused on air treatment and cold supply chains.
The 2026 Verdict: Record Growth
The numbers from the 2026 edition tell a story of a booming market. Despite the geopolitical climate, the show grew aggressively:
- Exhibition Space: 16,400 sqm – a 21% increase from 2025
- Exhibitors: 213 companies from 7 countries – a 33% jump
- New Faces: 104 companies made their debut, including giants like Daichi and TION
- Professional Visitors: 9,666 specialists from 20 countries and 81 Russian regions
What Defined AIRVent 2026?
The exhibition was structured into eight key sections, covering fans, ductwork, central air conditioners, refrigeration units, and building automation. However, the true highlights were in the ancillary programming.
1. The Inaugural AIRVent Awards
In a sign of the industry‘s maturation, the 2026 show hosted its first-ever awards ceremony. The focus was heavily on innovation and energy efficiency—two keywords that are currently driving Russian procurement.
- Top Innovation: VRK Plant won for its “TOPLINE concealed slot ventilation diffuser.”
- Top Energy Efficiency: THERMEX ENERGY won for a chiller with free-cooling capabilities for data centers.
2. The 9th International Ventilation Congress
With 70 speakers and 816 attendees (up 31% from 2025), the Congress addressed the engineer‘s pressing question: how to build a “safe microclimate” using modern technology while navigating sanctions.
3. The Digital Ecosystem (Aquaflame Connect)
A key takeaway from the event was the push for year-round B2B engagement via the Aquaflame Connect platform, allowing buyers and sellers to maintain relationships long after the exhibition halls close.
The Colossus: Aquaflame 2027 (February)
Date: February 1–4, 2027
Location: Crocus Expo (Concurrent with AIRVent)
If AIRVent is the specialist, Aquaflame is the generalist powerhouse. Held concurrently in the adjacent halls of Crocus Expo, Aquaflame is the 30th edition of Russia‘s leading exhibition for heating, water supply, plumbing, and pools.
Massive Scale, Massive Buyers
While AIRVent focuses on air movement, Aquaflame focuses on the pipes, boilers, and pumps that move water and heat. It is notably larger.
- Exhibition Space: 32,500 sqm
- Exhibitors: 587 companies from 12 countries (163 were new)
- Visitors: 23,149 independent professionals
The “Chinese Surge”
A defining trend of the 2026 Aquaflame show was the massive presence of Chinese manufacturers stepping in to fill the void left by Western brands. The Chinese delegation included 250 companies from 16 provinces, with heavy hitters like Xin Jie Pumps, Frog Pumps, and Zhejiang A fo nda showcasing large pavilions.
Hot Products on the Floor
The event served as a launchpad for new engineering solutions tailored to the Russian market:
- Boilers: DKM launched its “Baikal” steam boiler series.
- Pumps: TAIFU introduced new 3GRS circulation pumps.
- Water Treatment: BWT demonstrated a record-breaking 4-second backwash filter.
Buyer Intent: The quality of visitors was extremely high. Organizers reported that 93% of attendees have a role in purchasing decisions, and 70% plan to buy products immediately after the show.
The Industry Veteran: CLIMATE WORLD 2026 (November)
Date: November 10–13, 2026
Location: Crocus Expo, Moscow
If you missed the February rush, or if you are looking to close the year with a major push, Climate World (also known as World of Climate) is your target. This is the “OG” (Original) of Russian HVAC events, run by EURO EXPO and the Russian Refrigeration Association (APIC).
What to Expect in November 2026
Unlike the February events which are a combined mega-week, Climate World stands alone in the autumn. It spans a dedicated 28,000 square meters, expecting over 500 exhibitors and up to 30,000 visitors.
The “Big Brand” Show
Historically, Climate World is where the legacy international giants show up. While the landscape has changed, the 2026 edition is expected to feature the Russian branches of global leaders alongside domestic champions. The exhibitor list from 2025 included names like Emerson, LG, Panasonic, Siemens, Haier, and Schneider Electric.
Strategic Positioning
For many procurement managers, Climate World is the final major event of the calendar year. It is often used to secure equipment for the following year‘s construction season.
- Key Focus Areas: Heating boilers, industrial refrigeration (a massive sector in Russia), and large-scale rooftop HVAC units for commercial buildings.
- The Atmosphere: Expect a heavier focus on industrial solutions and refrigeration warehousing compared to the residential-heavy Aquaflame.
Strategic Overview for Industry Professionals
Moscow offers a bifurcated HVAC calendar: a massive “Winter Week” in February and a specialized “Autumn Summit” in November.
| Event | Date | Location | Key Focus | Target Audience |
|---|---|---|---|---|
