From April 27 to 29, 2025, the 36th China Refrigeration Exhibition will grandly open at the Shanghai New International Expo Center. As a leading indicator for the global HVAC and refrigeration industry, this year’s exhibition is themed “Intelligent Connectivity for Heating and Cooling—Sharing a Sustainable Future.”

As a leading brand in HVAC and refrigeration drive-control systems, STEP made a stunning debut at the event, showcasing a wide range of HVAC solutions as well as its star products—including the AS800G4 series, AS710M, AS530S, and the E6 series—demonstrating in full force its innovative achievements in energy-saving, consumption-reducing, and intelligent control. Through technical exchange sessions, the launch of the new AS800G4 series, and numerous media interviews, STEP became the center of attention, fully highlighting the company’s technological leadership and innovative vitality in the fields of HVAC and industrial control.

Unlock the “Traffic Code” | Five Major Thematic Activities

Centered around the theme of “Smart-Driven + Scenario-Based Interaction,” the exhibition booth featured five key thematic activities: interactive check-in events, interviews with industry leaders, technical exchange sessions, fixed-location raffles, and premieres of new products. By combining dynamic and static displays with interactive experience zones, the booth created an immersive exhibition experience. The event showcased application achievements of variable-frequency drive technology in scenarios such as supercomputing centers, heat pumps, high-speed systems, and high-voltage applications. Over the three-day period, the booth attracted more than 3,000 professional visitors who stopped by to engage in discussions and consultations. The consultation and negotiation area was packed, drawing intense attention from design institutes, engineering contractors, equipment manufacturers, investors, and industry media alike. As a result, the booth has become one of the most popular “technology traffic hubs” within the exhibition hall.

In fact, the Invertek Variable Frequency Drive Systems Division has also delivered exceptionally strong performance in the market. Despite the economic downturn and a sluggish market environment, the division bucked the trend in the first quarter of 2025, achieving substantial growth. In an interview, Mr. Li Xiaoyong, General Manager of the Variable Frequency Drive Systems Division, emphasized that enterprises must burn continuously like a flame, sustaining their vitality through self-disruption. Intelligent variable frequency drive technology is precisely the crucial spark that ignites this “living fire.” It is not only the heart of the equipment but also the “neural center” where data, algorithms, and application scenarios converge—driving the industry’s leap from “mechanical execution” to “intelligent evolution.” Upholding “technological innovation” and “customer value” as its twin driving forces, Invertek has consistently achieved numerous breakthroughs, establishing comprehensive technological barriers across the entire value chain—from underlying algorithms to specific application scenarios.

Insights into Trends | Jointly Exploring Paths for Low-Carbon Transformation

On the afternoon of April 27, the STEPeng Technical Exchange Conference, themed “Miniaturization of General-Purpose Drive Products and Strategies for Coping with Harsh Environments in the Era of Smart Heating and Cooling Trends,” attracted nearly a hundred industry experts, customer representatives, and media personnel. The event featured technical presentations by Shu Zhenqiang and Xie Haifeng, technical experts from STEP Variable-Frequency Drive Systems Division, and also included in-depth discussions with several senior engineers and partners. During the exchange conference, numerous customer representatives shared their practical needs based on their own experiences. The lively scene of industry collaboration and ecosystem co-creation vividly demonstrated the mutual value of technology empowerment and scenario-based implementation.

New Product Launch | Pioneering New Frontiers in Inverter Technology

On the afternoon of April 28, amid keen anticipation from a large audience, everyone witnessed another remarkable milestone for STEP in the field of high-voltage variable-frequency technology—the debut of the AS800 Series G4 high-voltage inverter! Mr. Liang Rui, President of STEP Group, and Mr. Li Xiaoyong, General Manager of the Variable-Frequency Drive Systems Division, personally unveiled this product that “redefines the technological boundaries of high-voltage inverters!” Following the unveiling, Xie Haifeng, a technical expert from STEP’ Variable-Frequency Drive Systems Division, provided a detailed introduction to the new product. After the press conference, Mr. Li Xinghe, Deputy General Manager of the Variable-Frequency Drive Systems Division, granted an exclusive interview to Industrial Control Network, revealing for the first time the technical challenges behind the development of the G4 model and how cross-disciplinary collaboration is helping China’s industrial sector transform from a “major energy consumer” into a “benchmark for green intelligent manufacturing.”
