Zhejiang Diya Shines at the 2025 China Refrigeration Exhibition, Innovative Technology Leads the Industry's Future

On April 27-29, 2025, Zhejiang Diya showcased multiple heavyweight products at the "2025 China Refrigeration Exhibition" and had in-depth exchanges with industry partners. Not only did they discuss cooperation with old customers, but they also made many new friends. At this exhibition, Diya showcased its "high-efficiency cascade refrigeration unit", "full range of stainless steel products", and "intelligent energy-saving refrigeration system", becoming one of the highlights of the entire event.  

Core products and technological highlights

1. All stainless steel corrosion-resistant solution

Diya launches "all stainless steel cold storage equipment", including:

All stainless steel air cooler ": made of SUS304/316 stainless steel material (pipe, fins, shell, motor bracket), completely solves the corrosion problem in salt spray and high humidity environment, suitable for harsh working conditions such as seafood processing and chemical cold chain.   

-Stainless steel U-shaped/V-shaped condenser: Optimized fluid design, improves heat transfer efficiency by 15%, and has super strong corrosion resistance, with a lifespan more than twice that of ordinary copper tube units.   

-Stainless steel integrated refrigeration unit: The whole machine is designed with rust prevention and high protection level, suitable for long-term stable operation in coastal and high humidity areas.   

2. Intelligent EC speed regulation energy-saving system

The highly anticipated feature of this exhibition is Diya's independently developed "EC Motor Intelligent Speed Control Refrigeration Unit", which has technical advantages including:

Adaptive variable frequency control ": Real time monitoring of the working conditions inside the warehouse through high-precision temperature sensors. When the temperature approaches the set value, the EC motor automatically operates at a reduced frequency (20%~100% stepless speed regulation), saving 30%~50% energy compared to traditional fixed frequency units.   

-Visual Energy Efficiency Feedback: The unit is equipped with an RGB status indicator light, which displays the current energy efficiency level through color changes (green → yellow → red) and allows real-time energy-saving data to be viewed through a mobile app.   

Internet of Things Integration: Supports Modbus RTU communication protocol, can be connected to the customer's central management system, and achieve remote start stop, fault warning, and energy efficiency analysis.

Industry application scenarios

-Cold chain logistics: The intelligent speed regulation function of the EC unit is perfectly adapted to refrigerated trucks and distribution centers that frequently open doors.   

-Pharmaceutical warehousing: meeting the demand for precise temperature regulation

-Food processing: Stainless steel series products are very suitable for the food cold storage industry

Zhejiang Diya will continue to promote the efficient, energy-saving, and intelligent development of the refrigeration industry with innovative technology!
