A site survey was quickly organised to confirm the required equipment as well as the install method and accessibility to the site.  Once on site the Sales Engineer determined that the best setup for the equipment would be to locate the 300kW air cooled chiller in the car park at ground level and run the pipework up the side of the building to the existing plant on the roof.

The three storey building meant a vertical climb of 18 metres for the pipework. It was agreed that the FM company would provide scaffolding at the side of the building whilst All Seasons Hire would position and secure the pipework. The pipework was installed by first affixing single flow and return lengths to the bottom of the scaffolding. Six lengths of hose were then carried up the scaffolding to the roof where they were assembled into two lengths and connected to the buildings existing system. The connected pipework lengths were then lowered down the scaffolding and connected to the already secured pipework at the bottom.

The fully installed pipework was then fully secured in place at both the top of the building and all the way down the scaffolding. Safety measures were also put in place to close the pathway in order to eliminate and trip hazard. The existing power supply was also utilized for the temporary chiller.
