Single vs three phase power supply
3 Phase refrigerated containers
3 Phase refrigerated containers come in 10, 20 and 40 foot sizes. They require a 3 phase 32 amp power supply. There are different types of 3-phase plugs, so when choosing a 3 phase refrigerated container, it is important to let us know what type of power outlet you have on your site.
The temperature range is from +18°C to -40°C.
Commercial and industrial facilities usually operate using a three-phase power supply.
Three-phase power supplies tend to accommodate higher loads, and delivers power at a steady, constant rate. However, do note that operating costs for three-phase reefers can be substantially more than single-phase refrigerated shipping containers.
Single phase refrigerated containers
Single phase refrigerated containers come in 20ft only.
These cold storage shipping containers use a 15 amp 240v power supply. The operating temperature range is + 10°C to -20°C. These units are very power efficient, providing savings of up to 60% when compared with the three phase option. The single phase reefer comes with internal lighting, personnel door, emergency release door as standard fittings.
Residential homes usually come with single-phase power supply systems.
