What container sizes does CIMIC supply?

Our reefer, dry and insulated lines are available in 10ft, 20ft, 20ft high cube, 40ft and 40ft high cube. Half-height, side open door, roll-up door, open-top, offshore and modular containers are built to project specifications.

Which refrigeration unit brands are available on your reefer containers?

We supply reefer containers fitted with Thermo King, Daikin and Carrier refrigeration units across our new and used ranges. Share your cargo set-point and on-site power supply so our engineers can recommend the right unit.

What certifications do your containers and factory hold?

CIMIC holds an ISO quality management certificate and a BV (Bureau Veritas) shipping certificate. Our offshore dry cargo containers are manufactured in compliance with DNV certification. ISO containers used in international transport should carry a valid CSC safety approval plate, and we confirm the documentation of each unit before shipment.

What is the difference between a reefer container and an insulated container?

A reefer container has an integrated refrigeration unit that actively cools or heats cargo to a set temperature and needs a power supply. An insulated container uses thickened foam walls to slow temperature change passively, with no power required, which suits shorter routes and temperature-sensitive cargo that does not need active freezing.

Are your used containers inspected before sale?

Our second-hand containers are units retired from shipping line fleets and are stored at various ports in China. We share photos and condition details of the specific unit you are buying so you can verify structure, doors, floor and, for reefers, the refrigeration unit before shipment.

Do you accept OEM, ODM and custom container orders?

Yes. We build tailor-made OEM and ODM containers and provide one-to-one engineering support. Stock and used units can usually be ordered in small quantities, while the minimum order quantity for custom builds depends on the specification.

Industry Macro Intelligence

Global Commercial & Industrial Landscape of Reefer Systems

The global refrigerated container fleet has surpassed 3.8 million TEU, transitioning rapidly from traditional insulated boxes into automated, telemetry-driven mobile cold-storage assets capable of maintaining biological integrity across trans-oceanic transit corridors.

Controlled Atmosphere (CA) Dominance

Modern global agro-perishable trade demands hyper-precise balance of oxygen (O₂), carbon dioxide (CO₂), and nitrogen (N₂). Manufacturers integrate dynamic membrane absorption technology to retard ethylene synthesis, extending the shelf-life of high-value commodities such as avocados, berries, and bananas by up to 35 days.

Active ethylene scrubbers with continuous gas monitoring
Leakage minimization via micro-cellular polyurethane foaming
Automated vacuum purging and hyper-low oxygen (1%) stabilization

Pharma & Biological Cold-Chain Compliance

The expansion of biopharmaceutical vaccines, blood plasma, and active pharmaceutical ingredients (APIs) has forced container manufacturing toward GDP (Good Distribution Practice) certification. Modern reefers deploy dual redundant refrigeration circuits and multi-sensor validation grids.

Ultra-low temperature (ULT) capability down to -70°C
NIST-traceable wireless temperature data probes
Integrated uninterruptible power supply (UPS) safety failovers

Intermodal Decarbonization Mandates

Regulatory frameworks such as the EU Emissions Trading System (ETS) and IMO 2030 targets necessitate a structural shift toward variable-speed scroll compressors, low Global Warming Potential (GWP) refrigerants (R-513A, R-1234yf, and natural CO₂ / R-744), reducing aggregate operating emissions by over 40%.

Deployment Paradigms

Localized Commercial Scenarios & Operational Integration

From deep-sea fishing fleets to land-locked Eurasian rail networks, reefer hardware is optimized for harsh field environments, mitigating risks of thermal degradation.

Marine Seafood & Pelagic Processing

Pelagic tuna and sashimi-grade catches require instant core crystallization to halt cellular oxidation. Blast freezing containers operating at -60°C are installed directly at harbor berths and fishing tenders, eliminating the intermediate cold-chain transfer losses common with inland refrigerated warehouses.

Eurasian Trans-Continental Railway Corridors

Traversing the "Belt and Road" railway from China across Central Asia to Western Europe involves extreme ambient fluctuations (-40°C in Siberian winter to +45°C in European summer). Specialized 45ft high-cube railway reefers utilize dual 1000L diesel clip-on gensets and satellite GPS thermal trackers to guarantee 20 days of autonomous uptime.

Remote Offshore Oilfield Rig Logistics

Drilling rigs in the North Sea, Gulf of Guinea, and South China Sea experience intense saline spray and rough handling. DNV 2.7-1 certified offshore containers feature integrated lifting sling sets, marine grade paint systems (>300μm dry film thickness), and explosion-proof Zone 1 / Zone 2 electrical fixtures for food catering and chemical storage.

Frequently Asked Questions on Reefer Container Manufacturing & Sourcing

Comprehensive technical guidance compiled by senior container design engineers and quality assurance specialists.

What container sizes and modified profiles are produced?

Our standard product line spans 10ft, 20ft standard, 20ft high-cube, 40ft standard, and 40ft high-cube refrigerated containers. In addition to ISO standardized envelopes, we build specialized equipment including 45ft high-cube intermodal railway reefers, 10ft/20ft DNV 2.7-1 certified offshore reefers, half-height open-top ore containers, and side-opening door units engineered for rapid warehouse cross-docking.

Which marine refrigeration unit brands are fitted onto your containers?

We partner with leading refrigeration machinery original equipment manufacturers, including Thermo King (Magnum Plus series), Daikin (Zestia series), and Carrier Transicold (PrimeLINE series). Units are custom-configured depending on the target cargo set-point (from ultra-deep -60°C blast freezing to ambient +30°C climate control) and available terminal/vessel electrical supply standards (380V/440V 3-phase 50/60Hz).

What industrial certifications and class society validations are held?

Manufacturing facilities operate under certified ISO 9001 quality management and ISO 14001 environmental frameworks. All export shipping containers hold Bureau Veritas (BV), ABS, or China Classification Society (CCS) type approval, and are fitted with authenticated CSC (Convention for Safe Containers) safety approval plates. Offshore units conform strictly to DNV GL 2.7-1 and EN 12079 structural offshore lifting standards.

What differentiates an active reefer container from a passive insulated container?

An active reefer container contains an integrated thermodynamic condensing/evaporating plant that actively chills or heats the internal envelope via electrical power or diesel gensets. In contrast, a passive insulated container lacks machinery and relies solely on high-density polyurethane wall insulation to minimize thermal bridge heat ingress, making it suitable for short regional drayage or dry cargo sensitive to extreme solar radiation.

What pre-trip inspection (PTI) and quality protocols apply to second-hand containers?

Every second-hand reefer container undergoes an exhaustive Pre-Trip Inspection (PTI) before port release. This includes micro-vacuum decay checks of refrigeration lines, electrical insulation megger testing of compressor windings, visual checks of door gaskets and T-floor airflow integrity, and full photographic documentation sent to the buyer prior to final loading.

Can custom OEM/ODM configurations be fabricated for specialized industrial projects?

Yes. We offer turnkey OEM/ODM custom container engineering. Modifications include internal hanging meat rails with reinforced roof purlins, blast-freezer floor ducting, side full-access bifold doors, explosion-proof Zone 2 electrical refits, and multi-compartment dual-temperature bulkheads for simultaneous frozen and chilled cargo hauling.
