Split PAC Hire – Split type units are ideal across a wide range of sectors including; office spaces, conference rooms, data centres, server rooms, shops and commercial spaces.

Split types offer exceptional cooling by lowering the whole room temperature. This is achieved by expelling the heat from the room to the external box; known as a out box or hex box. This box blasts out the hot air via up to 30m of umbilical lines. The unit inside the room blows out cool air whilst removing warm air allowing for a whole room cooling solution to be achieved.

This unit can come with up to 30m of umbilical lines to expel warm air. The outbox can be placed either indoor or outdoors – into a space where warm air can be dispersed. The umbilical lines can come in any length up to 30m; efficiency wise these work best when there is no excess or slack. We have various lengths of lines and can accommodate requirements allowing for the most effective cooling solution for your business.

We highly recommend split air conditioning solutions when it comes to data centres and server rooms. Often with other types of air conditioning such as evaporative cooling moisture is added to the air which over time can be damaging to servers and vital equipment. The split type units however do not add any moisture in their process of cooling. Warm air is simply removed and cool air is replaced; making it ideal for this setting.
