CAREL & Conela develop cooling units for seed storage

CAREL and Conela Refrigeração have collaborated on the development of the DEMETRA line, a range of cooling units designed for climate-controlled seed storage in agricultural environments.

The solution targets applications where maintaining stable environmental conditions is critical to preserving seed viability, particularly in high-volume agricultural markets.

Environmental control requirements in seed storage
Seed storage requires controlled temperature, humidity, and air quality to maintain germination capacity and biological stability over time. Deviations in these parameters can lead to moisture imbalance, metabolic degradation, and reduced seed performance.

The DEMETRA cooling units are designed to maintain stable storage conditions, supporting long-term preservation and reducing losses linked to environmental variability.

Integrated cooling and control architecture
The system combines variable-speed BLDC compressors, Power+ inverters, and electronic expansion valves (ExV), all managed by a programmable control platform. This configuration enables continuous adjustment of cooling capacity based on real-time storage conditions.

Variable-speed compressors reduce energy consumption by matching output to demand, while electronic expansion valves provide accurate refrigerant flow control, improving system stability and response time.

Remote monitoring and system supervision
The units are equipped with a supervisory system that enables remote monitoring of operating parameters such as temperature, humidity, and system performance. This allows operators to adjust settings and detect deviations without on-site intervention.

Continuous monitoring supports preventive maintenance and long-term optimization of system performance.

Operational performance and reliability
The integration of cooling, control, and monitoring technologies improves reliability and consistency in storage conditions. Stable operation reduces the risk of environmental fluctuations that can affect seed quality.

Enhanced system design and control precision have also enabled extended warranty coverage, reflecting improved durability and predictable performance.

Application in agricultural infrastructure
The DEMETRA line is intended for use in seed storage facilities where environmental control directly influences agricultural productivity. By combining advanced cooling units with digital control systems, the solution supports modernization of storage infrastructure and more consistent seed preservation outcomes.

The collaboration between CAREL and Conela Refrigeração demonstrates how integrated cooling units can be applied to maintain controlled storage environments and support efficiency in agricultural supply chains.
