Why Clean Fridge Coil Units?
A commercial refrigerator is the heart and backbone of every kitchen. It is the most indispensible unit in a commercial kitchen or restaurant. Keeping a commercial refrigerator up and running is therefore very essential. In turn, proper care must be taken to keep you FDC (Forced Draft Cooler) clean.
The FDC is the evaporator unit of the cool room. It contains the cooling coil and fan unit. The air within the coolroom is continualy circulated through the FDC unit to keep the room cool. Therefore, is it essential that the coils and unit are clean and free of microbiological contaminants, such as bacteria mould and fungi that colonise on the cooling fins creating toxic allergenic organic fragments otherwise known as macromolecular organic dust. This contaminated dust is then distributed throughout the coolroom by the fan. In turn, the quality of the air within the coolroom is compromised and can result in food contamination, costly customer complaints and in some cases can lead to a large range of chronic health complaints, such as headaches, nausea, respiratory complaints and eye and skin irritations.
The biofilm, dust and grime build up on the cooling fins of the FDC can have a detrimental effect to your business. Biofilms will attach themselves to the fins on the cooling coil and etch into the surface to provide a secure holding. In turn, this etching can eat away at the cooling coil and will, over time, degenerate the cooling coils ability to perform efficient heat transfer. Biofilm presence also acts as an insulation media between the cooling coil and the air flowing through the unit. This results in the temperature of the air flowing through the FDC not being reduced enough to keep the coolroom cool in which the compressors run continuously to compensate for the poor temperature transfer. This poor heat transfer results in increased energy consumption and increased cost or running. Lack of efficiency and increased energy consumption can also be attributed to blockages in the coil caused by dust and dirt that gets caught on the biofilm building up over time.
How We Can Help
Dunbar Services' trained technicians inspect the FDC and physically remove the buildup of microbiological contaminants, dust and debris by pressure cleaning the cooling fins from both sides, cleaning the fan units, protective grills and the condensate trays to waste. On completion, we use an advanced sanitiser containing enzymes which target and breakdown any remaining biofilm and microbiological contaminants. This leaves a microscopic layer on the cooling fins which retards the growth of mould and bacteria for up to six months. Regular cleaning of your coolroom FDC units will have the benefits of reduced breakdowns, increased efficiency, decreased energy consumption, increased hygiene, healthier staff and mitigation for OH&S requirements.
