CA Equipment & Products
CSDS supplies and integrates the full Controlled Atmosphere equipment stack: oxygen reduction, CO₂ scrubbing, ethylene management, gas analysis, climate control, gas-tight doors, and the data platform that ties them together. Each component is selected and sized against the specific crop, tonnage, and pull-down profile — not off a generic spec sheet.
Activated-carbon scrubbers that hold CO₂ at the product setpoint automatically. Scrubbers draw room air through adsorption beds that regenerate in cycle, so CO₂ stays stable without manual venting. Sized from small CA facilities through to multi-thousand-tonne apple storages.

Vacuum Swing Adsorption nitrogen generators that pull O₂ down from ambient to the CA or ULO setpoint. Output is matched to room volume, pull-down window, and door-opening profile so the atmosphere stays on target during normal operation.

Dynamic Controlled Atmosphere systems that safely run fruit at the lowest practical oxygen setpoint, just above the threshold where anaerobic fermentation begins. Built around room sensing, gas analysis, and fast-response control logic.

Catalytic converters that oxidize ethylene (C₂H₄) to CO₂ and water, protecting ethylene-sensitive crops such as kiwi and pears. Paired with ppb-level ethylene analyzers where the storage program requires it.

Room-level controllers coordinate refrigeration, gas generation, scrubbing, ethylene, humidity, and alarms. Supports CA, ULO, and DCA logic with per-room setpoints and scheduled changeovers through the storage season.

A cloud-oriented data platform that gives owners and service teams real-time visibility into every room, historical trends, alarm logs, and remote setpoint review across the whole site.

A mobile-friendly operator and service interface for live room status, alarm notifications, and quick visibility into key CA conditions while away from the control panel.

Electrochemical, infrared, and photoacoustic analyzers mounted on a multi-room measurement manifold. Accurate, drift-corrected readings are the foundation of every CA and especially DCA program.

Pressure-relief bladders, sampling lines and manifolds, gas-tight penetrations, pressure gauges, condensation management, and the small-items kit that makes the difference between a leaky CA room and a stable one.

Pallet-bag CA for berries — blueberries, red currants, cranberries — delivered as group or individual-pallet systems with a nitrogen generator, CO₂ supply, compressor, and a berry-specific climate controller. Ideal for operators who do not need or cannot justify a full CA room.

Small-scale CA research facilities built around individually controlled 50–500 kg containers for cultivar trials, post-harvest research, and new-program development. Each container runs its own atmosphere, ethylene, and humidity profile.

Insulated metal panel construction with gas-tight joints, sealed floors and ceilings, CA-rated sliding and hinged doors, pressure relief valves, and observation ports. The envelope is tested for leakage before the atmosphere is ever pulled down.

CA rooms fail at the interfaces — the panel joint, the door seal, the analyzer tubing, the scrubber regeneration schedule. We take responsibility for the complete package: selection, sizing, layout, piping, electrical, controls, commissioning, and service.
Tell us the crop, tonnage, number of rooms, and whether you are building new or retrofitting existing cold storage. We will scope the equipment package that fits the operation.
