    Temporary Cooling


    350kW Cooling 8x 50kw AHU’s

    Temporary Warehouse Cooling

    The Challenge;

    A challenging project…

    A commonly used phrase, but what does it really mean. This project really did present challenges in terms of equipment specification, installation and health and safety issues.

    The client required a cooling system to maintain 8 isles of its warehouse for storage of temperature critical product, including chocolate and creamed coconut.

    Summer temperatures in excess of 23 degrees were causing stored chocolate to bloom- fat bloom appears as a whitish coating on the surface- obviously not desirable for the consumer.

    Creamed coconut squares were starting to melt with oil dripping from packaging.

    The client was under extreme pressure to manage the temperature in these areas to minimise losses of product and maintain contractual obligations.

    A particular problem to overcome for this project were space issues. Restricted floor space, narrow isles and a need for maximum high level air distribution meant that cooling capacities and effective air distribution would not be feasible from floor mounted units.

    Another contractor in the past had positioned AHU’s externally, cutting large holes in the buildings structure to install ducting. The overall results were not effective. Air flow/ cooling capacity were not adequate and reinstating the buildings fabric expensive.

    The Solution;

    After detailed site and structural surveys ACR proposed high level mounting of ACR 110 AHU’s units. The low profile, high capacity and structural integrity of these units suited them to this application where safe lifting and positioning were critical.

    The units were lifted to high level by a specialist lifting team using an electric hoist, and then turned and rested on the racks.

    The top racks were later cleared to maximise air projection.

    The units were fed with 2″ flow and return insulated risers- a total of eight were fed from a 3″ chilled water main. A 350 kw portable chiller was installed with buffer tank and pump.

    Warehouse cooling systems require coolers to be fitted outside the building

    The externally fitted water chiller. This machine cools water that passes through hoses connecting it to the internal air handling units.


    A great install, carried out in a safe and controlled manner. From design, through install and operation, this project was successfully realised.

    The system remained in reliable operation for a total of 20 weeks through the summer months meeting the customers target temperatures. Towards the end of the project it was even mentioned that the warehouse was feeling chilly… music to our ears.


    Cooler for warehouse air conditioning can be fitted onto racking to maintain clear workspace

    The air handling units on this project were fitted at high level to give effective cooling down the complete isle. This also maximised the storage space available.
