We have several different models in our fleet of temporary mobile air conditioners to suit most applications.
They come in a variety of styles and capacities which can be tailored to your specific situation.
Although all portable air conditioning works on the same basic principle our mobile units can be split into two distinct groups.

Monoblock Air to Air.
Split Portable Air to Air.

A monoblock Air Conditioner uses an exhaust hose (similar to that used on a tumble drier) to discharge hot air.
The split portable Air Conditioners use a condenser box connected via an umbilical cord containing flexible refrigerant lines to dispose of the hot air.

The capacity of an Air Conditioning unit is often measured in BTU's.
BTU's or British Thermal Units are a measure of heat energy. (You may have noticed it on your gas bill.)

Our monoblock Air Con units are available with outputs ranging from 5800 BTU's up to 8000 BTU's.
The split portable AC are available from 9665 BTU's up to 14200 BTU's.

If you want to calculate roughly how many BTU's your work place will require, here is a simple calculation.

Multiply the length x width x height of the area you want to cool down using feet.

This is the size of your area in cubic feet, now multiply this number by (a factor of) 5 which will give you the amount of cooling required in BTU's.

Using a factor of 5 covers a typical office where there is no excess of personnel or heat generating equipment.

If it helps you to understand the amount of cooling required you can divide the BTU's by 3412 and the result is in Kilowatts.

Most of us know what a 3 Kilowatt (10236 BTU's) heater feels like, well you would get the reverse, 3 Kilowatts of cold air.

Remember that it may be better to use a number of smaller units in a large area to achieve a more even distribution of chilled air.
