Controlled atmosphere (CA)
Goods that often get infected with pests may be best treated in airtight chambers. Controlled atmospheres are airtight chambers or containers that can get products such as nuts, corn, rice, cocoa, coffee, spices, dried fruit, seeds, legumes, tobacco, soya wheat and barley pest free—quickly and efficiently. This technique is approved by various organic schemes and is often applied in conventional supply chains as well due to increasing safety and cost considerations.
Clean and safe
Go for non-toxic fumigation
Controlled atmosphere fumigation is applied to control pests in dry commodities and food supplies and is extremely suitable for both preventive and curative treatments. This technique is based on the creation of a low-oxygen regime/content in a specially constructed gastight treatment chamber or container.
Foolproof and bioproof
No resistance
Mortality rate of 100% of all live stages, such as eggs larvae, purpae and adults
No toxic chemicals
CA uses in-situ nitrogen from the ambient air, which does not require any toxic chemicals
No degassing concerns
CA chambers use ambient air to produce Nitrogen. removing complex logistics in N2 supplies
No harm to (organic) products
Permitted in organic production programs such as EU-Organic, USDA-NOP, Japan JAS and Bio Suisse
No harm for the environment
Treatment facility safe for workers, consumers and the environment.
Chamber and container installations
Our Controlled atmospheres are available in 2 main formats: Tailor made chamber installation at your facility, or in a container for solutions requiring less space.
CA Chamber installation
The Control Union Controlled Atmosphere system enables the establishment of ideal, oxygen-free treatment environments within hermetic chambers, eliminating any possibility of insect survival (eggs, larvae, pupae, or adults).
Our Controlled Atmosphere chambers are customizable to accommodate small or large quantities of products requiring treatment, tailored to your logistical requirements.
Due to their capacity to accommodate high volumes of goods simultaneously, these chambers represent one of the most convenient and effective airtight spaces for fumigation. They can be installed in any desired location and are offered in a range of sizes.
CA Container installation
Fitted containers provide an ideal solution, especially in space-constrained environments. These airtight containers can be conveniently placed either within or outside your facility, offering flexibility in placement.
Similar to our Controlled Atmosphere chambers, the CA Container installation service caters to varying volume requirements. Each container is capable of fumigating up to 15 metric tons of goods per 40-feet container, providing an effective solution for treating large quantities of products.
The machine room: design and options
Controlled Atmosphere Chambers require a separate machine room, distinct from the treatment chamber, to perform treatments effectively. These can be set up either in a separate machine room or within a containerized mobile machine room.
Each Controlled Atmosphere setup includes the following essential elements: GA Atlas
Copco®,Compressor with integrated dryer,
• Nitrogen generator
• Compressed air components
• Temperature humidity and o2 sensors
• Control Union software equipped in English
• Power supplies from (CA) an (MA) switchboxes to all components
CE standard material incl.
Buffertank
Every Controlled Atmosphere includes an Atlas Copco GA Compressor®
Every treatment from Control Union is backed by Atlas Copco GA Compressors®, ensuring reliable and efficient treatments every single time. With their robust design and advanced engineering, they ensure maximum uptime and energy efficiency, resulting in significant cost savings.
One machine can handle multiple Chambers simultaneously
One machine room is able to hande multiple CA chamber at once. Our systems are designed to maintain the quality of perishable goods over extended periods. The system consists of several large, interconnected storage units, each equipped with a temperature probe, an oxygen measuring unit, and an over/under pressure valve to ensure optimal conditions within. These units are connected through a series of air pipes and valves to a central machine room housed in a container. This room contains a low-oxygen converter, crucial for maintaining an atmosphere with less than 1.5% oxygen content.
24/7 monitoring solutions
Our cloud-based software solution is accessible on all mobile devices, including smartphones and tablets, as well as through cloud services, enabling both on-site and remote monitoring of the heat treatment process. The platform is easy to use by design, making non-experts able to easily monitor the progress of heat treatments. Our solution guarantees results, with built-in functionality to confirm the successful conclusion of treatments, ensuring both energy cost and treatment duration are minimized for efficiency and savings.
