A refrigerator truck or chiller lorry (also called a reefer), is a van or truck designed to carry perishable freight at low temperatures. Most long-distance refrigerated transport by truck is done in articulated trucks pulling refrigerated hardside (box) semi-trailers , although insulated curtainsiders are common in some countries.
Dry cooling towers (or dry coolers) are closed circuit cooling towers which operate by heat transfer through a heat exchanger that separates the working coolant from ambient air, such as in a radiator, utilizing convective heat transfer. They do not use evaporation and are air-cooled heat exchangers.
The Santa Fe Refrigerator Despatch (SFRD) briefly experimented with dry ice as a cooling agent in 1931. The compound was readily available and seemed like an ideal replacement for frozen water. Dry ice melts at −109 °F or −78.33 °C (versus 32 °F or 0 °C for conventional ice) and was twice as effective thermodynamically.
Whilst refrigerated containers are not common for air transport, total loss dry ice systems are usually used. [3] These containers have a chamber which is loaded with solid carbon dioxide and the temperature is regulated by a thermostatically controlled electric fan, and the air freight versions are intended to maintain temperature for up to ...

Schematic diagram of a cryogen-free, or dry, dilution refrigerator precooled by a two-stage pulse tube refrigerator, indicated by the dotted rectangle. A 3 He/ 4 He dilution refrigerator is a cryogenic device that provides continuous cooling to temperatures as low as 2 mK , with no moving parts in the low-temperature region.
Great Dane, formerly known as Great Dane Trailers, is a Chicago, Illinois based manufacturer of truck dry van, refrigerated van and flatbed semi-trailers.Established in 1900 by J.P. Wheless and T.H. McMillan as the Savannah Blowpipe Company [1] in Savannah, Georgia, it has gone on to become one of the world's largest manufacturers of commercial truck trailers.
When the outside air's dry- and wet-bulb temperatures are low enough, a water-side economizer can use water cooled by a wet cooling tower or a dry cooler (also called a fluid cooler) to cool buildings without operating a chiller. They are historically known as the strainer cycle, but the water-side economizer is not a true thermodynamic cycle.
