Refrigeration in retail

The efficiency of refrigeration in retail environments is critical as food retailers make most of their profit from chilled and frozen foods. Air Handling Units (AHU) are typically mounted on the roof of the building so chilled air has to be transported over longer distances, requiring optimal insulation, zero leaks and effective vapour seals.

Spiralite ductwork is ideal for this application as the thermal properties of the ductwork is optimised, resulting in no condensation (unlike metal ducting) and therefore no requirement for vapour seals.

In summary:

  • Now being used in major UK supermarket groups to deliver a complete cooling system which is practically maintenance free
  • The system can hold temperatures below -3 degrees from the AHU, which is typically mounted on the roof of the building, all the way to the chiller cabinets and cold rooms which can be as far as 90 metres away
  • The roof ductwork is made up of 30mm thick pre-insulated Spiralite with a 40mm thick thermal insulation and a 13-ply VentureClad laminate. The internal is 30mm thick pre-insulated Spiralite with a 5-ply VentureClad laminate

The advantages of this for retailers are:

  • Lower capital costs
  • Efficient operation and maintenance
  • Significant energy savings
  • No thermal transfers or condensation
  • Air leaving AHU is similar temperature to that arriving in refrigeration units
