Technicool provides the most efficient solutions possible and in combination with a huge CO2 refrigeration plant for the cold store extension, has provided a matching glycol heating system. Without control the temperature difference between the slab and the soil and the layers of the slab can cause icing and expansion, and the consequent frost heave literally raises the floor – an expensive problem. Technicool’s ingenious solution recovers waste heat from the main CO2 plant and sends it through pipes in the slab, keeping the freezing at bay.
