Design & Construct
Turnkey CA facility design, engineering, and construction
CSDS designs, engineers, and builds Controlled Atmosphere storage rooms and full keeping complexes as a single coordinated scope — from gas-tight envelope detailing and door selection through refrigeration, CA equipment, controls, and commissioning.
7 Capabilities
What we coordinate under one scope
Strong CA rooms come from decisions that are made together — envelope, doors, refrigeration, CA equipment, and controls. Here is how we break out the work so nothing falls between disciplines.
CA Installation
We design and deliver Controlled Atmosphere installations tailored to the crop, cultivar, storage window, and site constraints. We recommend the right combination of O₂, CO₂, ethylene, and humidity control technology so the room holds its atmosphere predictably over a multi-month campaign.
Gas-Tight Doors
CA rooms are only as tight as their openings. We specify and coordinate gas-tight doors from leading manufacturers, detail the seals, frames, and pressure equalization, and integrate them with the panel system so atmosphere loss stays within the target leak-rate budget.
Gas Tightness & Envelope Sealing
Every panel joint, penetration, wall-to-ceiling transition, and door opening is detailed and sealed for CA performance. We supply and install high-quality sealing materials, flash-tested assemblies, and pressure-relief valves to hold the envelope within spec and pass the pressure-decay test.
Refrigeration Design
Refrigeration is selected and sized for the produce load, pull-down requirement, and long-term holding conditions — not just a nameplate number. We engineer evaporators, suction groups, defrost strategy, and humidity control so temperature and RH stay on target inside a sealed CA room.
Planning a Keeping Complex
For new facilities, we plan the full keeping complex — CA and regular storage, sorting and grading lines, intermediate holding, shipping docks, offices, and staff areas — around your site, access, throughput, and phasing. The goal is a layout that works in year one and still works ten harvests later.
Design & Engineering
We produce detailed specifications and construction-ready drawings for cold store construction, refrigeration selection, gas-tight door schedules, CA equipment integration, and controls. Documentation is prepared for permitting, tendering, and a clean hand-off to the build team.
Turnkey Project Delivery
When you want a single accountable partner, we deliver the project turnkey — planning, design, engineering, construction, CA and refrigeration installation, commissioning, and local service coordination — working with trusted regional partners so maintenance and support stay close to your site.
How we deliver
One coordinated team, one accountable scope
A CA keeping complex is a coordinated operating environment. We keep architectural, civil, refrigeration, CA, controls, and commissioning decisions in one place so they reinforce each other rather than fight each other on site.
- Single point of contact from concept through commissioning and first storage season
- Early gas-tightness and leak-rate targets built into the panel, door, and penetration design
- Refrigeration, humidity, and CA equipment sized together around the actual produce load
- Controls and monitoring designed with the operator in mind — clear alarms, remote visibility, and documented responses
- Phased retrofits on live sites coordinated around harvest windows and existing storage capacity
