Please take a look at our “Portables Calculator” just above the FAQ section. As long as you know the length and width of you space in metres the calculator will provide an instant cooling load and suggested model. To hire this unit please call us to arrange. In some cases, if the area in Metres is too large for a portable unit / large cooling load you will be directed to give us a call. This isn’t because we don’t have a solution but that we will require a little more information (possible site survey) to look at multiple portable units or a chiller/air handling unit/fan coil combination. In both cases the team will be pleased to help on 0800 840 4210.
