April 10, 2026 – The three-day China Refrigeration Expo 2026 came to a successful close today at the Beijing · Capital International Exhibition Center. The event featured 1,041 participating companies and institutions from 30 countries and regions, covering a total exhibition area of 115,000 square meters, with over 70 concurrent conferences and activities.
SASWELL participated throughout the expo with professional presentations and enthusiastic service. Its booth (B3-B41) remained highly popular, welcoming more than a thousand professional visitors, system integrators, and HVAC engineers from home and abroad. During the expo, the SASWELL team engaged in deep technical dialogues with industry experts, overseas buyers, and building automation companies, resulting in multiple preliminary cooperation intentions.
1. Expo Conclusion: A Successful Three-Day Event
The 2026 edition of China Refrigeration Expo once again demonstrated its position as a global hub for HVAC&R innovation. With record participation and a strong focus on digital intelligence and carbon neutrality, the event provided an ideal platform for technology exchange and business matching.
2. SASWELL Booth Highlights: Strong Engagement Throughout
SASWELL participated throughout the expo with professional presentations and enthusiastic service. Its booth (B3-B41) remained highly popular, welcoming more than a thousand professional visitors, system integrators, and HVAC engineers from home and abroad. During the expo, the SASWELL team engaged in deep technical dialogues with industry experts, overseas buyers, and building automation companies, resulting in multiple preliminary cooperation intentions.
3. VAV Control Solution: The “Hit” Product at SASWELL’s Booth
Among all the products displayed, the Variable Air Volume (VAV) control solution generated the highest number of inquiries and the strongest customer interest – unanimously recognized by the team and visitors as the “booth hit.” Many building automation integrators and commercial air conditioning contractors expressed clear interest after an in-depth understanding, and some overseas customers even initiated preliminary technical discussions on site.
4. Why SASWELL’s VAV Solution Stood Out
The reason why SASWELL’s VAV solution stood out lies in its precise market positioning and technical differentiation:
- Compared to conventional DDC controllers that require extensive low‑level code programming, long commissioning cycles, and high labor costs, SASWELL’s HDC218 uses parameter‑based pre‑configured logic. It achieves integrated control of temperature, pressure, airflow, and CO₂ without script writing, greatly reducing project delivery difficulty.
- Compared to integrated VMA actuators that have closed functionality, high maintenance costs, and only support simple temperature control, SASWELL decouples the controller and actuator. Any 0‑10 V damper actuator can be connected, avoiding the “lock‑in” risk of a single supplier.
- Moreover, while maintaining the universally accepted BACnet MS/TP transparent communication protocol and industrial‑grade accuracy, the total system cost is only about one‑third that of leading international brands – achieving an excellent balance between performance and cost.
- For demanding environments such as laboratories, cleanrooms, and pharmaceutical plants, SASWELL’s VAV controller can simultaneously manage differential pressure gradients and air change rates, delivering 0.1 Pa‑level pressure differential control accuracy. This capability was highly praised by laboratory engineering contractors and hospital construction experts at the expo.
5. Full Product Portfolio Well Presented
In addition to the VAV control solution, SASWELL also showcased its color touch screen thermostats / wired controllers (2.8‑inch to 10‑inch, covering heat pump, VRF, fresh air, and multi‑split control), the three‑constant/five‑constant premium real estate dew point control solution, the LoRaWAN energy‑efficient retrofit solution, the HEMS home energy management system, as well as proportional valves / balancing valves / thermal actuators, and the air conditioning control series (covering FCU/RTU/AHU terminals). Together, these products demonstrated SASWELL’s complete intelligent control ecosystem – from home energy management to commercial building retrofits, and from premium real estate to critical environment control.
6. Deepened Brand Influence through Technical Exchanges
During the expo, the SASWELL team held in‑depth discussions with several building automation companies and overseas customers on topics such as BACnet and Modbus protocol integration in VAV systems, and energy‑saving control strategies for multi‑zone VAV systems. In addition, SASWELL actively used the AI‑powered “Business Radar” online invitation and negotiation system, which was launched for the first time at this year’s expo, to establish efficient supply‑demand matching channels with many high‑quality customers.
7. Future-oriented HVAC Control Ecosystem
SASWELL remains committed to technology‑driven innovation, deeply cultivating multi‑protocol technologies and intelligent control algorithms including BACnet, Modbus, LoRaWAN, Zigbee, and Matter, striving to provide global users with a complete intelligent control ecosystem – from home energy management to large commercial buildings, and from high‑end real estate to critical environments.
Although China Refrigeration Expo 2026 has concluded, SASWELL’s innovation in high‑precision VAV intelligent control will not stop. We thank every guest and customer who visited the SASWELL booth. We look forward to deeper conversations and cooperation with you, jointly ushering in a new era of green, intelligent HVAC control.
