Coil Cleaning

The cooling coils are a vital part of the Air Conditioning system. Generally they are an assembly of copper tubes to carry the cooling medium (water or refrigerant) covered with Aluminium Fins which the air passes through.

They transfer heat from the space to the cooling medium which in turns transfers the heat outside. They are constantly wet due to condensation of water from the air returned from the space. While the returning air is filtered there is always a small amount of dust which passes through. Due to this water and dust, the coils are prone to biological growths which affect the efficiency of heat transfer and the quantity of air which is circulated. This obviously can adversely affect the quality of air that we breathe.

Clean-Air has developed a range of techniques, products and equipment to clean a variety of coil types in different states of contamination. Our unique 2 part Foaming Coil Cleaner is the leading product for Coil Cleaning available. We measure and compare air pressure drop readings across the cooling coils to know that we are achieving a positive result. Coils which suffer consistent biological contamination or areas of high level cleanliness such as Hospitals or Aged Care will benefit from Steril-Aire UVC Coil Treatment.

Poor techniques and harsh chemicals can physically damage the coils or even compact the contamination into the centre of the coil. Replacement of Cooling Coils is an extremely expensive business with lengthy disruptions to the systems operation.
