Controlled Atmosphere, DCA & Cold Storage Technical Support in Canada

Controlled Atmosphere (CA) storage means measuring and regulating O₂ and CO₂ levels inside sealed storage rooms. By lowering oxygen and managing carbon dioxide, CA slows fruit respiration — extending storage life and preserving firmness and quality well beyond standard refrigeration.

Dynamic Controlled Atmosphere (DCA) dynamically adjusts oxygen levels close to the physiological limit of the fruit, with safety margins. Operating closer to that limit can improve quality retention for premium varieties — but it demands disciplined calibration, monitoring and support, since a poorly maintained DCA system can perform worse than standard CA.

As oxygen is pushed toward the fruit's lower limit, the room approaches the point where anaerobic fermentation can begin. Ethanol detection can help identify early signs of anaerobic fermentation risk — giving operators an input to hold or adjust the O₂ setpoint before quality is affected.

Yes. CO₂ scrubbers help remove excess CO₂ from CA/DCA rooms. Rodrigues CA provides pre-season inspection, performance and capacity testing, component repair and ongoing maintenance for scrubber systems across brands and configurations.

Yes. Gas analyzers and monitoring systems are essential for reliable storage decisions. We support analyzer setup, validation and reading-reliability checks so that the O₂, CO₂ and — where relevant — ethylene data operators depend on stays accurate through the season.

Yes. Rodrigues CA is technology-agnostic and provides technical support, maintenance and troubleshooting for CA systems regardless of brand or configuration — including older or mixed-equipment facilities. Component sourcing or warranty service may require manufacturer involvement for some brands, which we clarify during the assessment.

Yes. Rodrigues CA works with leading technologies in controlled atmosphere, DCA, CO₂ control, gas analysis and cold storage systems. For international technology companies needing a qualified Canadian field partner, we can provide local installation, commissioning and after-sales support. Any commercial arrangements are established through formal written agreements.

Rodrigues CA may work with different controlled atmosphere and post-harvest technologies depending on the project. Any official partnership or manufacturer authorization must be confirmed through formal commercial agreements. We do not claim official partnership or authorization with any manufacturer unless formally agreed in writing.

The Remote Assessment (from CAD 300) is conducted via video call plus review of photos, videos and documentation — effective for initial evaluation or straightforward systems. The On-Site Assessment (from CAD 1,500) involves a hands-on facility inspection, recommended for complex multi-room or DCA operations. Both result in a written report with findings, risk ranking and a priority action list. On-site visits are subject to scope, province and scheduling.

Rodrigues CA is based in Montreal, Quebec. Remote technical support — diagnostics, consultation, DCA data review and operational guidance — is available nationwide. On-site service (installation, commissioning, hands-on maintenance) depends on project scope, province and scheduling. Contact us to discuss your location and what would be feasible.
