Refrigerated truck transport (fresh produce)

Carrier Global Corporation (Palm Beach Gardens FL; NYSE: CARR; ~$22B revenue 2023) is the world's largest manufacturer of transport refrigeration units (TRUs) for trucks and trailers under the Carrier Transicold brand. Carrier Transicold holds an estimated 40% share of the US trailer refrigeration unit (TRU) market. Carrier was separated from United Technologies Corporation (UTC) in April 2020 as a standalone public company. Primary North American TRU manufacturing is at the Carrier Transicold plant in Suwanee GA (and sourcing from Carrier Transicold Shanghai, China). Carrier also acquired Chubb fire and security (divested 2021), Cold Chain Technologies, and Viessmann Climate Solutions (HVAC; Germany) in 2023 for €12B — expanding beyond transport refrigeration into building HVAC. The Carrier Transicold X4 7300 series is the dominant platform in North American reefer trailers. Carrier Transicold's Container division manufactures refrigeration units for ocean-going reefer containers at its Montluel, France facility.

Trane Technologies plc (Dublin Ireland; NYSE: TT; ~$20B revenue 2023) is the parent of Thermo King, the world's second-largest transport refrigeration unit (TRU) manufacturer. Thermo King holds approximately 35% of the US TRU market. Thermo King traces its history to 1938 when Joseph Numero invented the first mechanical refrigeration system for a truck — transforming fresh produce distribution in America. Ingersoll Rand spun off Trane Technologies in 2020 (alongside the sale of its industrial segment). Thermo King's North American manufacturing is centered at its Bloomington MN facility (near Minneapolis). Thermo King also manufactures in Galway, Ireland (European production hub). Thermo King's Advancer reefer trailer unit is the primary competitor to Carrier's X4 platform. Trane Technologies is pursuing an 'Uplifting the World' sustainability strategy that has included switching Thermo King trailer units to CO2 and electric-drive refrigeration systems.

A.P. Møller – Mærsk A/S (Copenhagen Denmark; Nasdaq Copenhagen: MAERSK; ~$51B revenue 2022 peak) is the world's largest container shipping company by fleet capacity (~17% global container market share) and, as a consequence, the world's largest single operator of refrigerated shipping containers (reefer containers). Maersk operates approximately 400,000+ reefer containers — roughly 17% of global reefer container capacity. Maersk's reefer container business is critical for the global fresh produce trade: bananas from Ecuador and Costa Rica, Chilean grapes and blueberries, South African citrus, New Zealand beef and kiwi, Peruvian avocados, and US apples and pears all move in Maersk reefer containers. Maersk has been actively expanding beyond ocean shipping into end-to-end cold chain logistics — acquiring Hudd Distribution Services (US temperature-controlled trucking) and Senator International (air freight) as part of its Logistics & Services strategy. In 2023, Maersk revenue normalized from pandemic highs but reefer container demand remained robust as fresh produce trade growth continued.

Daikin Industries Ltd. (Osaka Japan; Tokyo: 6367; ~¥4.4T revenue 2023) is the world's largest air conditioning manufacturer and a major manufacturer of refrigeration units for ocean shipping containers (reefer container units) through its Daikin Container division. Daikin's reefer container refrigeration units compete with Carrier Transicold container units in the ocean reefer shipping market. Daikin Container's manufacturing is concentrated in Japan and China. Daikin is also the world's largest producer of fluorocarbon refrigerants and fluoropolymers — the chemical feedstocks for HFC refrigerants including the R-452A and R-448A blends that are replacing R-404A in reefer equipment. This creates a unique dual position: Daikin manufactures the reefer equipment AND the refrigerants that run in it, AND the refrigerants' feedstock chemicals. Daikin's acquisition of Goodman (Australia/US HVAC) and McQuay International (US commercial HVAC) makes it the dominant global HVAC manufacturer alongside Carrier and Trane.

CMA CGM Group (Marseille France; privately held by the Saadé family; ~€74B revenue 2022 peak) is the world's third-largest container shipping company and the second-largest operator of reefer (refrigerated) containers globally. CMA CGM operates approximately 280,000 reefer containers — roughly 12% of global reefer container capacity. CMA CGM's reefer business is concentrated in fresh produce from Latin America (bananas from Ecuador, Guatemala, and Honduras; pineapples from Costa Rica; citrus from Peru), Africa (South Africa citrus, West Africa bananas), and Mediterranean/North Africa routes. In 2022, CMA CGM expanded its reefer fleet and acquired CEVA Logistics (cold chain and freight management) to compete with Maersk's end-to-end logistics strategy. CMA CGM's Air division (acquired Air France Cargo partnership) added air reefer capacity for high-value time-sensitive produce (cherries, asparagus, fresh herbs). The Saadé family's majority ownership makes CMA CGM the largest privately-held shipping company in the world.
