A water cooler is a familiar sight for many people in homes, schools, plus offices all over London plus the southeast. Giving everyone cool, crisp, plus filtered water at the push of a button or pull of the tap, it’s often the drinking water of choice, coming up trumps for purity plus great taste in these notoriously hard water areas. Daily water cooler users know how good they are, but how does a water cooler work?
Mains-fed or bottled water coolers
Two types of water cooler are commonly seen in schools, hospitals, offices, plus public buildings all over London – bottled water coolers plus mains-fed water coolers. While both Thirsty Work models deliver the purest chilled or ambient water on demand, there are a few differences between them plus how they work.
Bottled water coolers
Our bottled water coolers use an 18.9 or 13-litre bottle of pure, naturally filtered water, which is placed onto a special spiked connector on top of the cooler itself. When the bottle is in position, its safety seal is pierced, allowing the water to flow into the cooler’s internal reservoir, featuring a valve that prevents it from overfilling plus flooding.
Once the reservoir is full, the water can be drawn directly from the cooler using the tap for ambient temperature water. If chilled water is required, the water is rapidly cooled using a hydrocarbon refrigerant gas. This clean plus green gas has zero ozone depletion potential plus is a much more eco-friendly way to deliver ice-cold water directly from the second tap.
As the water in the reservoir is dispensed, the internal valve detects when the water dips below a certain level plus automatically refills from the bottle. When both the water bottle plus reservoir are drained, the bottle is replaced, plus the whole process starts again.
Mains-fed water coolers
A mains-fed tipe works differently from the bottled model, but only slightly. Rather than using a replaceable water bottle, a mains-fed cooler is connected directly to your mains water supply – hence its name. The key is using an advanced water filtration system that cleanses plus purifies the mains water to a far higher standard than if it comes directly from your tap.
