The Watercooler A-Z

The various words and terminology used within the watercooler world can be confusing, but today we’re making it easy as ABC by sharing our watercooler alphabet with you…


Water that is at room temperature, it is neither heated or chilled. The Borg & Overström watercoolers that offer ambient water are; the b2, the b3, the b4, the b5, the u1, and the u2.

Bottled watercooler

A water cooler that is fed by a bottle. The bottle is inverted onto a spike which feeds a reservoir with water. Here at Borg & Overström, we believe that the most efficient, and hygienic watercoolers are point of use watercoolers (we’ll be describing these a little later on), but for those who are unable to install a point of use watercooler, our b2 machine can be converted into a bottled machine with this bottle conversion kit.

Countertop watercooler

A watercooler that sits atop of a surface, such as a kitchen counter. This is often more convenient when space is at a premium, and also when accessibility factors need to be considered. The Borg & Overström b2, b3, and b4 are all available in a countertop configuration.

Direct chill

The direct chill system utilises cooling technology to ensure water is hygienic and fresh. The direct chill system takes water directly from the supply source, and chills it in a coil on its way to the dispenser faucet. This ensures water is fresh, and reduces the impurity levels. The Direct Chill system is used in all of our watercoolers, and you can read why we are so proud of it, here.


From wall brackets and drip trays, to branded glass flip top bottles and ultra violet filter kits, there are plenty of products available to enhance the use of your watercooler. You can find the Borg & Overström accessories range, here.

Floor-standing watercooler

A watercooler that stands on the floor, generally reaching around waist height to allow for easy interaction and usage. This is the most popular configuration for watercoolers, as they can be installed in most locations, and be accessed by many. Borg & Overström offer many floor-standing watercoolers, including; the b2, the b3, the b4, and the b5.


The world of watercoolers can be confusing and complex. That’s why we’ve created a specifier to help you find the right watercooler for you. You can try our specifier, here.

Hot and cold

Just as we change our moods, sometimes we prefer our water at varying temperatures. That’s why Borg & Overström watercoolers offer both a hot and cold water dispense.

Leak detector

A device that can be fitted to Borg & Overström watercoolers. It activates an automatic shut off of the device’s water feed if it detects a leak, providing you with reliability and peace of mind. You can find the leak detector devices here.

Mains fed

(See point of use)

No leaks

When you use a bottle top dispenser, once the contents of the bottle have been used, the bottle requires replacing. On average, these bottles contain between 15 -19 litres of water. When a bottle replacement is required, the bottle must be removed, and the new, full, bottle lifted and fitted in its place. Often during this process, spillages occur with the bottles are swapped over due to the gravitational effect of the heavy weight of the water. With a point of use machine, water comes directly from the source, eliminating risk of leaks. You can read more about this, here.

Optimal configuration

We know that your office or kitchen is unique. Each have different demands and restraints, and you need a watercooler that will meet and overcome these. That’s why our water dispensers are available in various heights, shapes, colours, and sizes, so you can find the optimal watercooler to suit you.

Point of use or plumbed in watercooler

Otherwise known as a ‘POU’ device. This watercooler is plumbed directly into the main source of water, and dispenses it through a tap, ensuring water is fresh, hygienic, and cool. You can read a little more about why Borg & Overström offer point of use watercoolers here.

Quality control

Every Borg & Overström dispenser is checked by hand, and pressure tested up to 15 bars of pressure. We create products that we trust and use ourselves, so we can be sure when recommending them to you.

Reverse osmosis

A water purification technology that uses a semi permeable membrane to remove ions, molecules, and larger particles.

Sparkling water

Also known as ‘carbonated water’. This is water into which has carbon dioxide gas under pressure has been dissolved in it. This provides the same fizz as many soda drinks, but with none of the calories or excessive sugar levels, you can read more about sparkling water here. Many of Borg & Overström’s watercoolers offer sparkling water alongside your chilled and ambient options, including the b3, the b4, the b5, the u1, and the u2.

Trade only

Borg & Overström operate on a 100% trade only basis. This means we sell to stockists, as opposed to end users. We work with our customers to set them up as approved Borg & Overström distributers, providing them with the training, support, and know-how they need to progress their own business.

Under-counter watercooler

Under-counter watercooler devices consist of a water tap situated on a counter, with the Direct Chill system and water dispense technology located in a discreet box under the counter. The Borg & Overström’s u1 and u2 are both under-counter watercooler devices.


Ultra violet rays can be used in water filtration systems in some water coolers. The direct exposure to UV can help to eliminate bacteria. Borg & Overström’s b3 watercooler offers the capability for UV water filtration, when used in conjunction with this Ultra Violet Filter Kit.

Waste kit

Waste kits can be installed when standard drainage is not available for your watercoolers, or to provide a drip tray overflow solution. Several of Borg & Overström’s waste kits also provide a level sensor, which will notify you when the device is at risk of overflowing. You can find our waste kits within our accessory range, here.
