Fresh Provisions. Clean Air. The Whole Voyage.
A sealed cold room ripens its own cargo: the ethylene that ripening produce gives off builds up and ages the entire store at once - so fruit and vegetables land in the bin halfway through the passage. SepcoTech's Onboard Air & Provisions category brings chemical-free air treatment to the spaces where the crew stores, cooks and lives. No chemicals. No filters. Made in Denmark.
What's actually going wrong on board?
Four complaints that come back from ships again and again - and where each one is answered.
Ethylene removal in the provision cold room breaks the ripening cycle that ages the whole store at once. Crews report roughly a week's extra shelf life, and a visible drop in spoiled goods.
The cold-store case →The MAC500s mounts high on a bulkhead and plugs in - no build-in, no downtime. For a new-build or refit with the deckhead open, the flush-ceiling MAC500c does the same job invisibly.
MAC500 Series →A few hours of ozone in a closed, empty space clears the smell from air, surfaces and fabrics - once the source has been cleaned out. For refuse rooms, emptied stores and cabins after smoke or spoilage.
OZ Series →The same contained UV-C runs safely 24/7 in cabins, mess rooms and the ship's hospital - a continuous reduction of airborne bacteria, viruses and mould supporting the cleaning routine already in place.
Where it earns its keep →Provisioning is a cost line, and a welfare line
Every crate of produce that spoils before it is eaten was bought, loaded, refrigerated and then thrown away - and on a long passage there is no restocking it. The same sealed spaces that ruin food also concentrate mould, bacteria and odour in the places the crew cannot avoid: the galley, the mess, the cabins, the hospital. Contained UV-C treats both problems at once, with no chemical stores to carry, no filters to buy and no consumable but a lamp. It is a small, cheap piece of equipment that shows up in the catering budget, in food waste, and in how well a crew eats and stays healthy at sea.
Two technologies, two jobs
Continuous, people-safe treatment of a space the crew is working in - and a periodic deep-clean of one they can leave.
Continuous UV-C - MAC500 Series
Runs 24/7 in occupied cold rooms, stores and accommodation. Strips ethylene, cuts bacteria, viruses, mould and odour - low-level ozone, no NOx, no filters. Three builds, four finishes, 230/115/120 V. Live: JIMCO.

Ozone Deep-Clean - OZ Series
Portable UV-C ozone units that reset a closed, empty space - odour from air, surfaces and fabrics in garbage rooms, emptied stores and cabins. Three sizes, recommended for 125–250 m³ of odour treatment, stainless or coated. Live: JIMCO.
Explore the OZ Series →Warning: ozone safety. The OZ series works by flooding a space with ozone - people and animals must not be present during a treatment cycle, and the space must be ventilated before re-entry. Aboard, treat that as an enclosed-space operation: ozone is heavier than air and pools in low spaces. The MAC500 Series makes low-level ozone by design, kept below CARB's 0.050 ppm limit on the certified UL build, and is safe for continuous use with the crew present. It does not flood the room the way the OZ series does. Before you run one, read what ozone does and doesn't kill, and when crew can go back in.

JIMCO - UV-C & Ozone Air Purification
JIMCO's MAC500 Series mounts in a ship's provision cold room and removes the ethylene gas that ripens produce, while cutting airborne bacteria, mould and odour. Crews aboard Mærsk container ships report fruit & vegetables lasting roughly a week longer, with units paying for themselves in saved waste within two voyages. Chemical-free, filter-free, Made in Denmark - supplied and supported by SepcoTech.
- ~1 week longer provision shelf life at sea, reported by Mærsk crews (JIMCO cites up to 14 days in an unnamed storeroom study)
- Airborne virus (MS2) down 99.9% after 3 hours; airborne bacteria and fungi down roughly three-quarters within 45 minutes in a separate test; no chemicals, no filters, no NOx
- Documented by the Danish Technological Institute and Analytical Laboratories, Singapore
- Building UV-C air treatment since 1993 - for Marriott, Hilton, Hyatt, Radisson, KFC and many McDonald's kitchens
- EU Environmental Award for Cleaner Technology (2000) for the photolytic oxidation process

Send us your room volumes - we'll do the sizing
One unit covers up to 60 m³, so the quote needs one number you already have: the m³ of each space you want treated. Tell us the spaces and we'll come back with the unit count and the right variant per room.
