Improved cool room performance

It is imperative that hygiene be maintained in refrigeration systems throughout the supply chain.

AerisGuard technology, the residual actions of which prevent colonisation of cool room surfaces for extended periods, can help.

A complete remediation and preventive treatment can:

• improve airflow

• reduce cool room energy usage by up to 10%, and

• increase shelf life and reduce spoilage through increased indoor air quality.

Typical refrigeration systems continuously recirculate unfiltered air through the forced draught coolers (FDCs).

This exposes the coil of the FDC to high levels of contamination.

When combined with the natural condensation that forms on the FDC the system becomes contaminated.

This contamination builds up gradually and exists unnoticed deep inside the unit.

Biofilm

A biofilm can be broadly defined as an aggregation of micro-organisms that have established contact with a surface and between each other by expressing polymeric substances.

Micro-organisms commonly go through stages of attachment, growth and dispersal to develop complex structures that have been described as ‘slime cities’.

Biofilms form at many surfaces but one of the most common is where water is in contact with a solid surface, as the two requirements for biofilm growth are the presence of micro-organisms and moisture.

Examples of this are dental plaque or the slippery coating on a rock.

The AerisGuard treatments consist of biocides that are impregnated into slow-release polymers that provide six months of residual protection against continuous microbial growth.

The polymers slowly dissolve in the moisture provided on the surfaces to release a trace amount of biocide.

This biocide actively prevents the formation of biofilm in:

• large scale refrigerated warehouses/ facilities of all shapes and sizes

• refrigerated trucks, and

• refrigerated sea-freight containers.
