Case Study- Temporary Cooling for Chocolate Storage

Temporary cooling for chocolate storage. Without doubt one of the most challenging projects we have ever completed. This emergency cooling installation presented challenges in terms of equipment positioning and safe working practices. However, in the end, and with much persistence, a great result was achieved for this happy client.

350kW Cooling 8x 50kw AHU’s

The Challenge- Temporary Cooling for Chocolate Storage

Indeed, this project was a real challenge in the purest sense. The client required a cooling system to maintain 8 isles of its warehouse for storage of temperature critical product, including chocolate and creamed coconut.


With summer temperatures in excess of 23 degrees the stored chocolate was beginning to bloom- fat bloom appears as a whitish coating on the surface- obviously not desirable for the consumer.


In addition, creamed coconut squares were starting to melt with oil dripping from packaging. All in all, the client was under extreme pressure to manage the situation to minimise losses of product and maintain contractual obligations.


Our first impressions of this project were centred around space issues. As well as restricted floor space, narrow isles and tall racking meant that effective cooling would only be feasible from high level units.


In the past another contractor had positioned AHU’s externally, brutally cutting large holes in the buildings structure to pass ducting through. The overall results were not effective. Air flow/ cooling capacity were not adequate and reinstating the buildings fabric expensive. Overall, a disappointment and a a situation we were determined to avoid for this temporary cooling for chocolate storage project.

The Solution

After detailed site and structural surveys, we proposed high level mounting of ACR LT50 ahu’s units. Crucially, the low profile, high capacity and structural integrity of these units suited them to this application where safe lifting and positioning were of utmost importance.


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


To further maximise air projection, the top racks were later cleared for temporary cooling for food storage.


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.


Summary- Temporary Cooling for Chocolate Storage

A great install, carried out in a safe and controlled manner. From design, through install and operation, this temporary cooling for chocolate storage 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.

    Certainly one of the largest and most challenging temperature control projects we have ever carried out. Measuring at 288,000 sq/mt and at a height of 20 metres, this area was partitioned from the main deep chill warehouse for a 15 degree storage chamber.
