Performance Features

High-Efficiency Refrigeration & Energy Saving

Integrating air-cooled condensers, expansion valves, and variable frequency drives, this system automatically adapts to grain stack heights while reducing power load and preventing thermal air backflow.

Specially Designed Air Delivery System

Built with air filters, centrifugal fans, and plenum chambers, the system prevents saturated humid air from entering grain heaps to preserve grain quality without moisture loss.

Smart PLC Control & Digital Customization

Features PLC programming, remote communication interfaces, and auto loading/unloading protections, alongside reservation timers and non-standard custom options tailored to client storage requirements.

FAQ

How do I select the right Grain Cooling System model for my silo?

Model selection depends on total grain capacity, target chilling temperature, and ambient conditions. Our product line ranges from YGLA-50 (56 kW cooling capacity) to YGLA-150 (145 kW), with airflow options spanning 4,000 m³/h to 13,500 m³/h (2,354 to 7,946 CFM) to accommodate diverse bin dimensions.

Can this system completely replace chemical fumigation during grain storage?

Yes. By lowering and maintaining grain pile temperatures consistently below 15°C (low-temperature) or 20°C (quasi-low-temperature), insect breeding and microbial respiration are suppressed naturally, achieving eco-friendly green storage without chemical residues.

How is the unit moved and installed at the site?

The system features an integrated mobile chassis with heavy-duty wheels and louvered protective panels. The complete machine is shipped fully assembled; site installation only requires connecting the 380V 50Hz power supply and attaching the air duct to your silo inlet.

Does the system support customized specifications and digital remote control?

Yes. All models come equipped with a PLC smart control cabinet featuring RS485/remote communication interfaces and reservation timer functions. Non-standard custom options can also be provided based on unique operational requirements.
