Outstanding purification

Firewall® patented and certified UV technology thoroughly purifies water all the way through to the dispensing nozzle, preventing viruses and bacteria getting into the system.

Remove 99.999% of odour and mould causing bacteria whilst enjoying up to five varieties of water; including large volumes of ice-cold and sparkling water all from one machine.

Continuous protection

For your peace of mind key surfaces of the WL7 Firewall® are infused with BioCote® technology, that continuously restricts microbial growth around the dispensing area.

This helps to reduce degradation of key surfaces and the potential for cross contamination.

Eco-friendly & efficient

When you choose one of our bottle-free drinking water systems, not only will you reduce your plastic waste, but our R600a natural cooling gas also reduces your carbon footprint.

Additionally, the WL7 Firewall® mains-fed water cooler comes with a programmable energy saving sleep mode to significantly reduce power consumption when the unit is not in use.


The system is engineered to deliver an abundance of ice-cold still and sparkling water and can dispense up to 17 litres per hour of water at near-freezing temperatures.

Refreshing water

The WL7 Firewall® uses our unique Ice Bath cooling system; engineered to deliver glass after glass of highly purified ice-cold water to meet the needs of the most demanding workplaces.

Easy to use

Offering the best user experience, the WL7 features a large dispense area, alongside a user friendly screen interface and water selection dial, allowing users to easily choose between 5 water options.
