Mains Fed Water Coolers

Sediment and chemical impurities can cause unpleasant tastes and odours and can also contribute to the formation of limescale in drinking water.

Mains Fed Water Coolers

3M can improve the quality of water by removing chlorine and bacteria which improves the taste and odour, removing cysts which can be very harmful to your health, and reducing limescale formation which can shorten the life of your mains fed water coolers.

3M's new range of AP2 filters are designed to provide the best quality water at a lower cost to your business and to the environment. 3M's miniturisation technology achieves a higher flow, with longer life, in a smaller filter. Our carbon block technology enables the 3M™ AP2-G range to produce the same high quality filter with the same great tasting filtered water. Filters from our AP1 and AP3 ranges also offer bacterial protection.

Chlorine Taste and Odour Removal in Mains Fed Water Coolers

One of the most common complaints of taste and odour of tap water is chlorine. Activated carbon provides a simple and effective means to reduce chlorine from mains fed water so you can enjoy fresh, clean tasting water straight from the water cooler. Activated carbon also can be effective at removing other water taints such as taste and odours caused by trace levels of organics in the water, which can cause for example earthy, chemical taints.

All activated carbons are not the same and 3M offers a range of high performance carbon based systems for chlorine, taste and odour reduction: try the 3M AP2 range, specifically designed for mains fed water coolers. Either through the use of novel, unique carbon block technology or linked with our pharmaceutical membranes they provide market leading performance for the reduction of chlorine, taste and odour, sediment, cyst and bacteria.

3M offers chlorine taste and odour removal in all products for mains fed water coolers, postmix and ice machines, Coffee, Vending machines and steamers as well as for water filtration in the home.

Scale Inhibition

Scale build up in hard water areas can cause your water cooler to breakdown prematurely, reduced efficiency, and both water level and temperature controls can be affected. 3M estimates that 3mm of scale build up can cause 25% energy loss in addition to unwanted and costly service calls.

For hard water areas we have polyphos based scale inhibition filters that dose polyphosphate into the water to coat areas where scale may form. This provides high-quality water while inhibiting scale growth in the cooler system and unnecessary downtime and service calls.

For further information on Scale Inhibition see our Scale Prevention Application section.

Bacterial Reduction

3M has added sterilising grade membranes to a number of product lines and can offer different levels of bacteria removal. This new technology offers high level protection and can be applied in all applications such as on mains fed water coolers.
