As the name suggests, portable air conditioners can be moved from one place to another on castors. Their size can be as large as window units, but they can be easily moved. Portable air conditioners are mostly used in industries, warehouses, temporary businesses etc.

Often, industrial warehouses are so big that a central cooling system cannot keep them cool. This is where portable air conditioners are required. The air conditioner can be moved according to the cooling needs of the workers and machines. Even some of the machines need spot cooling for their optimum use.

Designed especially for industrial use, some portable air conditioners have higher capacities than the usual ones ranging from 3.5 to 60 tons. Air conditioners with Freon as well as evaporation technology can be hired. However, air conditioners which works on evaporation technology are expensive than those with Freon technology.

Organizers of functions and events such as weddings, live performances, football matches, and more also rent portable air conditioners. They are placed in strategic positions so that they cool throughout the venue. After the program the air conditioner can just be wheeled away to the next location.

Sometimes, vehicles on the move rent portable air conditioners. Ships carrying perishable foods often have to rent a portable air conditioner. The water transport vehicles like boats and ships often use portable air conditioners.

Portable air conditioners can be hired on both a long term and a short-term basis. Factories require long-term rentals that can vary from a couple of months to even years. However, social events rent portable air conditioners for just a couple of days. The rent depends on the type of air conditioner rented and the duration for which it is rented.
