Agrovent Drive Systems
The gearbox is an essential component of ventilation and refrigeration systems in cold storage facilities. It provides automated control of dampers, ensuring precise opening and closing based on temperature, humidity, and CO₂ signals. By guaranteeing airtight sealing, the gearbox reduces energy losses and lowers the load on refrigeration and ventilation equipment. Its design parameters — including torque, control type, and protection level — allow for reliable operation under demanding conditions. As a result, the gearbox helps maintain an optimal microclimate and significantly extends the shelf life of stored produce.
The Role of the Gearbox in Cold Storage Facilities
The gearbox is responsible for automatic valve control — opening and closing dampers based on control system signals such as temperature, humidity, and CO₂ levels. It also ensures airtight sealing and energy efficiency, preventing air leaks and reducing the load on refrigeration and ventilation equipment.
Key Technical Parameters
- Torque: 50–120 Nm (depending on damper size and weight).
- Rotation angle range: 0–90° (smooth or step control).
- Control type:
- ON/OFF (2-position): for simple systems.
- 0–10 V or 4–20 mA (analog): for smooth control.
- Digital (Modbus, BACnet): for integration into smart systems.
- Operating speed: 15–60 seconds per full stroke (to avoid sudden pressure changes and turbulence).
- Power supply: 24 V AC/DC or 220 V AC.
- Operating temperature range: –30…+60 °C (with anti-freeze protection).
- Protection class: IP54 or higher (suitable for dusty and humid storage conditions).
- Spring return function: automatic closing in case of power loss, ensuring emergency protection.
- Service life: at least 60,000–100,000 cycles.
- Automation interface: compatible with climate control systems, sensors, and SCADA platforms.
Conclusion
In summary, the gearbox provides precision, reliability, and energy efficiency in the operation of supply and exhaust dampers. This makes it possible to maintain an optimal microclimate and extend the storage life of produce.
