COLD STORES
First in – last ordered
Building an industrial scale cold store is no mean feat and requires a huge amount of consulting, planning, designing, project management and installation effort – not to mention money – just to build. Jason King, operations manager at Thermatek, explains.
A
cold store will be in operation for many years so must be designed to stay at the right temperature whilst being constantly
used and abused.
The designer will have taken fire requirements into account as well as the insulating properties of the walls and ceilings, performance of the freezer condensers, lighting, power requirements, racking positioning, and entry and exit points. There is one other vital part of the freezer design that is crucial

to the long-term stability of the freezer. A part which, if overlooked, could cause months of very costly downtime.
A good design will also incorporate measures for
Frost Heave Prevention. Without an efficient frost heave prevention solution in place, the floor of the freezer will, over time, suffer serious degradation, potentially leading to lost revenues while the freezer is shut down to have the floor removed and replaced or, at very least, significantly repaired.
Prevention is always better than the cure. When compared with the possible results (and costs) of frost heave damage, the cost of a sub-floor heating system is negligible and ensures continuous long service and reliability. Frost Heave occurs when the refrigeration
process acts to remove heat from below the freezer. This heat transfer through the floor insulation becomes significant with time and eventually removes enough heat from the sub-soil
