Electric vs. Diesel-Powered Refrigerated Containers:
When choosing a refrigerated container, one key decision is whether to go with an electric-powered model or a diesel-powered one. Both types offer unique benefits and are
Although it requires additional handling compared to the wheeled system, the reefer rack has the advantage of being land effi cient, taking up a footprint of 320 square feet for four 40 foot contain-ers, compared to a 400 square foot per container footprint associated with a wheeled system.
Diesel reefers can also be associated with ineffi ciencies, as a diesel engine is required to be in a constant state of operation in order to keep the container cool. Reefers have two primary cycles of operation: Electric-Powered Trailer Refrigeration Unit Market Study and Technology Assessment. Prepared by Shurepower for NYSERDA. June 2005.
When moving over the road, reefer containers require a mobile power source, or genset. An alternative to a full electric reefer is the hy-brid electric reefer in which a small diesel engine serves as the source of power when electric power is not available.
When stationary at the dock, these units are plugged into grid power at an electrical terminal, and when in motion on a ship, they are powered by a ship's electricity generators. When moving over the road, reefer containers require a mobile power source, or genset.
